application monitoring requirements

But some forms of monitoring require the analysis and diagnostics stage in the monitoring pipeline to correlate the data that's retrieved from several sources. Within an application, the same work might be associated with the user ID for the user who is performing that task. The ongoing results should be reported in near real time to help detect immediate issues. Apply to Monitoring Specialist, Support Specialist, Customer Service Representative and more! SLA configurations, alerting, and reporting capabilities. All sign-in attempts, whether they fail or succeed. Also to get intuitive dashboards either significant effort or 3rd party plugins are required. Using the previous example: Note that for a dashboard system to work effectively, it must have the raw data to work with. This strategy uses internal sources within the application, application frameworks, operating system, and infrastructure. Data gathered for metering and billing customers might need to be saved indefinitely. IDERA has made its name through deep SQL Monitoring capabilities. As an example, rather than saving minute-by-minute performance indicators, you can consolidate data that's more than a month old to form an hour-by-hour view. Collecting ambient performance information, such as background CPU utilization or I/O (including network) activity. Automatic transaction traces and a unified end-user view into transactions, including mobile app and synthetic or web-based applications. Considering the elastic nature of the cloud, and to avoid the necessity of manually retrieving telemetry data from every node in the system, you should arrange for the data to be transferred to a central location and consolidated. The instrumentation data-collection subsystem can actively retrieve instrumentation data from the various logs and other sources for each instance of the application (the pull model). Using a monitoring agent is ideally suited to capturing instrumentation data that's naturally pulled from a data source. Don't write all trace data to a single log, but use separate logs to record the trace output from different operational aspects of the system. Retrace Overview | January 6th at 10am CST. No transaction tracing view. Ideally, all the phases should be dynamically configurable. Hot analysis of the immediate data can trigger an alert if a critical component is detected as unhealthy. This will help you more easily trace sequences of events. They are great at answering that question of “What did my code just do?”, Read more: Using developer APM tools to find bugs before they get to production. Most all of them target large enterprises and IT operations. For example, an entry to a method can emit a trace message that specifies the name of the method, the current time, the value of each parameter, and any other pertinent information. Capturing data at this level of detail can impose an additional load on the system and should be a temporary process. Dashboards can be organized hierarchically. Tracing execution of user requests. For Azure applications and services, Azure Diagnostics provides one possible solution for capturing data. Monitoring APIs continually throughout the CI cycle and detecting and fixing issues early on contributes to continuous deployment and. APM is the IT discipline that focuses on application monitoring and management. Azure Diagnostics gathers data from the following sources for each compute node, aggregates it, and then uploads it to Azure Storage: For more information, see the article Azure: Telemetry Basics and Troubleshooting. High-traffic elements might benefit from functional partitioning or even replication to spread the load more evenly. An example of a user request is adding an item to a shopping cart or performing the checkout process in an e-commerce system. You can then use this information to make decisions about whether the system is functioning acceptably or not, and determine what can be done to improve the quality of the system. You can implement the storage writing service by using a separate worker role. SmartBear is poised to expand this product creating a major player in the Application Performance Management vendors. (It must be recorded in its original format.) A single instance of a metric is usually not useful in isolation. In a system that requires users to be authenticated, you should record: Monitoring might be able to help detect attacks on the system. Determine which features are heavily used and determine any potential hotspots in the system. Alerting is the process of analyzing the monitoring and instrumentation data and generating a notification if a significant event is detected. Instrumentation can generate considerable volumes of data. The raw data that's required to support SLA monitoring is similar to the raw data that's required for performance monitoring, together with some aspects of health and availability monitoring. The instrumentation data must be aggregated and correlated to support the following types of analysis: You can calculate the percentage availability of a service over a period of time by using the following formula: This is useful for SLA purposes. Implementing Application Monitoring Proactively. Profiling. The volume of data storage that each user occupies. The date and time when the error occurred, together with any other environmental information such as the user's location. IDERA is known for having an intuitive dashboard and allow for quick insights, Precise uses these dashboards to make it one of the best APM Monitoring Tools available today. You can then analyze this data to determine which parts of the application might cause performance problems. A crash dump (if the application includes a component that runs on the user's desktop). Robot Monitor is comprehensive performance and application monitoring software for your Power Systems server. This information can also be useful in determining whether to repartition an application or the data that it uses. This data is also sensitive and might need to be encrypted or otherwise protected to prevent tampering. AppDynamics caters to larger enterprises and offers a SaaS APM option as well as an on-premise option. Audit information is highly sensitive. The operator can then take the appropriate corrective action. You can track the performance of the test client to help determine the state of the system. This allows administrators to see the percentage of CPU engaged on each VM or the fluctuation of network traffic requests by bandwidth and IP addresses over time. An APM solution is like the black box of an airplane. In many cases, an analyst will need to dig through the chronology of the underlying operations to establish the root cause of the problem. For scalability, you can run multiple instances of the storage writing service. The typical requirements of this scenario. Provide sufficient context to enable a developer or administrator to determine the source of each request. 7 Requirements for Monitoring Cloud Apps and Infrastructure 1. If a user reports an issue that has a known solution in the issue-tracking system, the operator should be able to inform the user of the solution immediately. Typically when you think of APM tools, you think of running them on production servers, but there are also APM tools that developers can use on their workstation while writing and testing their code. We would call it “APM light”. Apart from the simplest of cases (such as detecting a large number of failed sign-ins, or repeated attempts to gain unauthorized access to critical resources), it might not be possible to perform any complex automated processing of security data. System uptime needs to be defined carefully. Capturing this information is simply a matter of providing a means to retrieve and store it where it can be processed and analyzed. Each of the scenarios described in the previous section should not necessarily be considered in isolation. The data that's required to track availability might depend on a number of lower-level factors. Usage tracking can be performed at a relatively high level. Don't mix log messages with different security requirements in the same log file. As described in the section Information for correlating data, you must ensure that the raw instrumentation data includes sufficient context and activity ID information to support the required aggregations for correlating events. What you need to do is to break down the business process of the application and then have the software emit events at major business components. Record all requests, and the locations or regions from which these requests are made. The SteelCentral AppResponse, AppInternals and Portal are all required to get a holistic view that you get through many other products. Visualizes application topology, deployments and environment changes in real-time. (For example, an alert can be triggered if the CPU utilization for a node has exceeded 90 percent over the last 10 minutes). The schema should be generalized to allow for data arriving from a range of platforms and devices. For example, Azure blob and table storage have some similarities in the way in which they're accessed. The resources that each user is accessing. This sets DynaTrace apart as an application performance tool. Data that's required for these purposes must be quickly available and structured for efficient processing. For example, rather than writing information by using System.Diagnostics.Trace, define an abstract interface (such as ILogger) that exposes logging methods and that can be implemented through any appropriate means. This document focuses on these scenarios as the most common situations for performing monitoring. It should also be capable of quickly alerting an operator when one or more services fail or when users can't connect to services. An example is that all help-desk requests will elicit a response within five minutes, and that 99 percent of all problems will be fully addressed within 1 working day. Monitoring applications to detect and respond to problems - before an end user is even aware that a problem exists - is a common systems requirement, especially for revenue-generating production … This data can help reduce the possibility that false-positive events will trip an alert. For example, instrumentation data that includes the same correlation information such as an activity ID can be amalgamated. The data from a series of events should provide a more reliable picture of system performance. But it might be useful to allow the system to raise an alert for the number of connectivity failures to a specified subsystem that occur during a specific period. When a user ends a session and signs out. Transaction tracking shows where the issues are occurring. Detect (possibly indirectly) user satisfaction with the performance or functionality of the system. Stackify Retrace. This data cube can allow complex ad hoc querying and analysis of the performance information. Components of a complete application performance management solution: Read our guide on What is APM to learn more. Designed to be less impactful from other solutions, reducing noise and false positives. Operating system errors (such as the failure to open a file correctly) might also be reported. No reporting across apps. You might be able to dynamically adjust the level of detail for the data that the performance monitoring process gathers. Make logs easy to read and easy to parse. Determine the overall availability of the system as a percentage of uptime for any specific period. Use the same time zone and format for all timestamps. You can also use the data to identify elements where the system slows down, possibly due to hotspots in the application or some other form of bottleneck. Endpoint monitoring. System uptime as presented by health monitoring should indicate the aggregate uptime of each element and not necessarily whether the system has actually halted. If your application uses other external services, such as a web server or database management system, these services might publish their own trace information, logs, and performance counters. Data presentation can take several forms, including visualization by using dashboards, alerting, and reporting. Note that in some cases, the raw instrumentation data can be provided to the alerting system. Database Deep Dive | December 2nd at 10am CST, Traces: Retrace’s Troubleshooting Roadmap | December 9th at 10am CST, Centralized Logging 101 | December 16th at 10am CST. Ideally, your solution should incorporate a degree of redundancy to reduce the risks of losing important monitoring information (such as auditing or billing data) if part of the system fails. SLA monitoring is closely related to performance monitoring. For example: You can implement an additional service that periodically retrieves the data from shared storage, partitions and filters the data according to its purpose, and then writes it to an appropriate set of data stores as shown in Figure 6. Log all critical exceptions, but enable the administrator to turn logging on and off for lower levels of exceptions and warnings. The initial data source for issue-tracking data is the user who reported the issue in the first place. This context provides valuable information about the application state at the time that the monitoring data was captured. This might involve running the system under a simulated load in a test environment and gathering the appropriate data before deploying the system to a production environment. The gathered information should be detailed enough to enable accurate billing. Figure 1 highlights how the data for monitoring and diagnostics can come from a variety of data sources. Cost*: $1323 – $3607 / Azure Offering Prices vary on Licensing Agreements (*See Microsoft Licensing for details as this per Core Costs). Figure 3 - Using a monitoring agent to pull information and write to shared storage. A disk that's exhibiting normal usage can be displayed in green. Predictive Analytics show possible issues before they occur. The key requirement is that the data is stored safely after it has been captured. Monitoring the performance and status of every CI; Every time the configuration of the IT estate changed I needed to know the impact that this would have on the business service; Historically, in an ideal world. For example, an operator might determine the response times for 99 percent of requests, 95 percent of requests, and 70 percent of requests. (SLA monitoring is described in more detail later in this guidance.) The system might also make guarantees for the rate at which requests are processed. In some cases, an alert can also be used to trigger an automated process that attempts to take corrective actions, such as autoscaling. In the event of a transient failure in sending information to a data sink, the monitoring agent or data-collection service should be prepared to reorder telemetry data so that the newest information is sent first. For example, your application code might generate trace log files and generate application event log data, whereas performance counters that monitor key aspects of the infrastructure that your application uses can be captured through other technologies. For example, in an e-commerce site, you can record the statistical information about the number of transactions and the volume of customers that are responsible for them. A cloud application will likely comprise a number of subsystems and components. Multiple Riverbed components are required to get the same in-depth results that come from other singular solutions. As a result, a large degree of manual intervention is often required to interpret the data, establish the cause of problems, and recommend an appropriate strategy to correct them. It can display information in near real time by using a series of dashboards. It might be appropriate simply to store a copy of this information in its original format and make it available for cold analysis by an expert. Analyzing and reformatting data for visualization, reporting, and alerting purposes can be a complex process that consumes its own set of resources. This information must be sufficient to enable an analyst to diagnose the root cause of any problems. Reporting is used to generate an overall view of the system. Self-described as an application intelligence platform, AppDynamics monitors application performance and then derives insights into how application performance is impacting business operations. This process is called root cause analysis. The deepest level allows for Database, Code level Stack Traces, and automatic Hung Transaction Resolution. Protecting the privacy and security of the system, users, and their data. Languages: .NET, Java, AJAX, IBM WebSphere WQ. Robot Monitor provides real-time system and application monitoring, one-click … For this reason, audit information will most likely take the form of reports that are available only to trusted analysts rather than as an interactive system that supports drill-down of graphical operations. Is it the result of a large number of database operations? This monitoring might require retrieving and parsing health data that these services supply. An important part of the monitoring and diagnostics process is analyzing the gathered data to obtain a picture of the overall well-being of the system. Information that's used for more considered analysis, for reporting, and for spotting historical trends is less urgent and can be stored in a manner that supports data mining and ad hoc queries. Logging exceptions, faults, and warnings. All commercial systems that include sensitive data must implement a security structure. Retrace is focused on being simple to use and affordable for developer teams of all sizes. Application monitoring tools ensure that developers are not flying blind! The different formats and level of detail often require complex analysis of the captured data to tie it together into a coherent thread of information. In reality, it can make sense to store the different types of information by using technologies that are most appropriate to the way in which each type is likely to be used. The article Enabling Diagnostics in Azure Cloud Services and Virtual Machines provides more details on this process. Track performance by application, user, transactions, business division, and location, Languages: .NET, Java, Expandable with custom/3rd party Management Packs. The application code can generate its own monitoring data at notable points during the lifecycle of a client request. Different endpoints can focus on various aspects of the functionality. Aside from the requirement to generate common audit reports, the tools for analyzing this data are likely to be specialized and kept external to the system. But from an availability monitoring perspective, it's necessary to gather as much information as possible about such failures to determine the cause and take corrective actions to prevent them from recurring. Additionally, regulatory requirements might dictate that information collected for auditing and security purposes also needs to be archived and saved. They are also being used more and more by developers and not just IT operations for application performance monitoring. This information can then be used to determine whether (and how) to spread the load more evenly across devices, and whether the system would perform better if more devices were added. The average processing time for requests. An unexpected surge in requests might be the result of a distributed denial-of-service (DDoS) attack. This is called cold analysis. Obtain information about the operational events of the system under normal use. Rather than saving old data in its entirety, it might be possible to down-sample the data to reduce its resolution and save storage costs. An exception in one level often triggers another fault in the level above. To address these issues, you can implement queuing, as shown in Figure 4. Figure 2 illustrates an example of this architecture, highlighting the instrumentation data-collection subsystem. If you are building your own dashboard system, or using a dashboard developed by another organization, you must understand which instrumentation data you need to collect, at what levels of granularity, and how it should be formatted for the dashboard to consume. What has caused an intense I/O loading at the system level at a specific time? You can use monitoring to gain an insight into how well a system is functioning. Some types of monitoring generate more long-term data. Azure: Telemetry Basics and Troubleshooting, Enabling Diagnostics in Azure Cloud Services and Virtual Machines, Monitor, diagnose, and troubleshoot Microsoft Azure Storage, View service health notifications by using the Azure portal, Performance diagnostics for Azure virtual machines, Download and install SQL Server Data Tools (SSDT) for Visual Studio. DynaTrace, previously known as Compuware APM, is touted as the first self-learning Application Performance Monitoring tool. If information indicates that a KPI is likely to exceed acceptable bounds, this stage can also trigger an alert to an operator. In this architecture, the local monitoring agent (if it can be configured appropriately) or custom data-collection service (if not) posts data to a queue. (The technique for generating and including activity IDs in trace information depends on the technology that's used to capture the trace data.). An operator can use the gathered data to: 1. Record and capture the details of exceptions carefully. The rates at which business transactions are being completed. Or, the system can deliver detailed step-by-step information as selected operations progress. Server monitoring—and monitoring computers in general—both involve enough telemetry that it needs to be a core focus. Gather data from key performance counters, such as the volume of I/O being performed, network utilization, number of requests, memory use, and CPU utilization. An alert might also include an indication of how critical a situation is. Each factor is typically measured through key performance indicators (KPIs), such as the number of database transactions per second or the volume of network requests that are successfully serviced in a specified time frame. The Internet Information Services (IIS) log is another useful source. Many of these factors might be specific to the application, system, and environment. They can also be generated from system logs that record events arising from parts of the infrastructure, such as a web server. Is this reflected in the database response times, the number of transactions per second, and application response times at the same juncture? The most critical aspects of security monitoring should enable an operator to quickly: To support these requirements, an operator should be notified if: The information that's provided to an operator should include the host address of the source for each request. You must be prepared to monitor all requests to all resources regardless of the source of these requests. Cost: $15 per month per server + data charges. The purpose of health monitoring is to generate a snapshot of the current health of the system so that you can verify that all components of the system are functioning as expected. Requirements will be broken down based on hardware and software monitoring. At other times, it should be possible to revert to capturing a base level of essential information to verify that the system is functioning properly. Real-time monitoring with sub-second analytics, Pre-built processing rules and dashboards, Complex Event Processing (CEP) engine for advanced application analytics and rules, Intuitive, easily defined dashboards provide insights at a glance. This information can also be used to help configure time-based autoscaling. Availability monitoring is closely related to health monitoring. A feature of security monitoring is the variety of sources from which the data arises. It has done no less with its APM solution as well. Enforce quotas. All faults, exceptions, and warnings should be captured with sufficient data for correlating them with the requests that caused them. For example, an organization might guarantee that the system will be available for 99.9 percent of the time. In the last few years, APM tools have become affordable and a must have for all businesses. The security system that manages user authentication. Remember that any number of devices might raise events, so the schema should not depend on the device type. A key feature to consider in this solution is the ability to support multiple protocol analytics (e.g., XML, SQL, PHP) since most companies have more than just web-based applications to support. An operator should be able to drill into the reasons for the health event by examining the data from the warm path. This approach enables an operator to filter data and focus on those thresholds or combinations of values that are of interest. The primary sources of information for auditing can include: The format of the audit data and the way in which it's stored might be driven by regulatory requirements. The following list summarizes best practices for instrumenting a distributed application running in the cloud. Access to the repository where it's held must be protected to prevent tampering. Many modern frameworks automatically publish performance and trace events. Analysis over time might lead to a refinement as you discard measures that aren't relevant, enabling you to more precisely focus on the data that you need while minimizing background noise. A developer can then make the necessary modifications to prevent them from recurring. And if not, the operator should be able to drill down and examine the underlying factors to determine the reasons for substandard performance. For example, reports might list all users' activities occurring during a specified time frame, detail the chronology of activity for a single user, or list the sequence of operations performed against one or more resources. Security monitoring can incorporate data from tools that are not part of your application. You may have to wait for enough data points to come in before you stop seeing false positives. (In an e-commerce system, a failure in the system might prevent a customer from placing orders, but the customer might still be able to browse the product catalog.). This is called warm analysis. It's also important to understand how the data that's captured in different metrics and log files is correlated, because this information can be key to tracking a sequence of events and help diagnose problems that arise.
