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. An example of a user request is adding an item to a shopping cart or performing the checkout process in an e-commerce system. The contents of a trace log can be the result of textual data that's written by the application or binary data that's created as the result of a trace event (if the application is using Event Tracing for Windows--ETW). The selection can be time-based (once every n seconds), or frequency-based (once every n requests). You may have to wait for enough data points to come in before you stop seeing false positives. An analyst must be able to trace the sequence of business operations that users are performing so that you can reconstruct users' actions. Nonrepudiation is an important factor in many e-business systems to help maintain trust be between a customer and the organization that's responsible for the application or service. That means that they specifically designed it to take the least resources possible. ManageEngine Applications Manager provides basic application monitoring tool. Deep SQL metrics and profiling available out of the box. This is called warm analysis. For example: If so, one remedial action that might reduce the load might be to shard the data over more servers. Additionally, your code and/or the underlying infrastructure might raise events at critical points. They can also be generated from system logs that record events arising from parts of the infrastructure, such as a web server. At some points, especially when a system has been newly deployed or is experiencing problems, it might be necessary to gather extended data on a more frequent basis. To address these issues, you can implement queuing, as shown in Figure 4. 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. For example, instrumentation data that includes the same correlation information such as an activity ID can be amalgamated. A disk that's exhibiting normal usage can be displayed in green. These external systems might provide their own performance counters or other features for requesting performance data. For example, emit information in a self-describing format such as JSON, MessagePack, or Protobuf rather than ETL/ETW. Application Discovery and Dependency Mapping (ADDM) is a core requirement for application monitoring. This information can assist in determining whether there are any location-specific hotspots. (Do services start to fail at a particular time of day that corresponds to peak processing hours?). Top-level dashboards can give an overall view of each aspect of the system but enable an operator to drill down to the details. Funnel analysis of multi-step transactions linking directly back to page content data. SLA configurations, alerting, and reporting capabilities. 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. Security issues might occur at any point in the system. A minute is considered unavailable if all continuous HTTP requests to Build Service to perform customer-initiated operations throughout the minute either result in an error code or do not return a response. For scalability, you can run multiple instances of the storage writing service. Stackify Retrace. 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. Figure 1 highlights how the data for monitoring and diagnostics can come from a variety of data sources. Precise is no different, leveraging the deep Database structure IDERA has expanded Precise into true APM solution. You can then quickly filter log messages by reading from the appropriate log rather than having to process a single lengthy file. You can make meaningful decisions about the performance and health of a system only if you first capture the data that enables you to make these decisions. All faults, exceptions, and warnings should be captured with sufficient data for correlating them with the requests that caused them. This might include some form of activity ID that identifies a specific instance of a request. An operator should be able to drill into the reasons for the health event by examining the data from the warm path. The schema might also include domain fields that are relevant to a particular scenario that's common across different applications. Monitors chained API transactions where the APIs need to be invoked in sequence, and contextual data needs to be passed from one call to the next. The application code can generate its own monitoring data at notable points during the lifecycle of a client request. Capturing this information is simply a matter of providing a means to retrieve and store it where it can be processed and analyzed. Determine whether the system, or some part of the system, is under attack from outside or inside. The monitoring agent that runs alongside each instance copies the specified data to Azure Storage. Make sure that logging is extensible and does not have any direct dependencies on a concrete target. App Monitoring Options. Once you start using them, they will become part of your standard tool-chain. The issue-tracking system should associate common reports. You can calculate availability for a service by using the technique described in the section Analyzing availability data. 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. In all cases, the gathered data must enable an administrator to determine the nature of any attack and take the appropriate countermeasures. This data cube can allow complex ad hoc querying and analysis of the performance information. Log information might also be held in more structured storage, such as rows in a table. Data presentation can take several forms, including visualization by using dashboards, alerting, and reporting. Tracing operations and debugging software releases. See “High(er) Availability Is a Hoax” for more background on … It's useful to store historical data so you can spot long-term trends. Synthetic user monitoring. Differences in Data. There is a wide range of application performance management and application monitoring (APM) tools on the market available for developers, DevOps teams, and traditional IT operations. A telemetry system is typically independent of any specific application or technology, but it expects information to follow a specific format that's usually defined by a schema. 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. This information must be sufficient to enable an analyst to diagnose the root cause of any problems. All timeouts, network connectivity failures, and connection retry attempts must be recorded. SmartBear is poised to expand this product creating a major player in the Application Performance Management vendors. Requirements will be broken down based on hardware and software monitoring. You can obtain this information by: For metering purposes, you also need to be able to identify which users are responsible for performing which operations, and the resources that these operations use. This process is called root cause analysis. Robot Monitor is comprehensive performance and application monitoring software for your Power Systems server. Does not work for non web apps without major code changes. Quest creates a good baseline for the APM requirements, but the interface can be somewhat confusing and clunky to find the details you are looking for. Multiple Riverbed components are required to get the same in-depth results that come from other singular solutions. This information can be captured as a result of trace statements embedded into the application code, as well as retrieving information from the event logs of any services that the system references. Ideally, an operator should be able to correlate failures with specific activities: what was happening when the system failed? For example, in an e-commerce system, the business functionality that enables a customer to place orders might depend on the repository where order details are stored and the payment system that handles the monetary transactions for paying for these orders. The raw data that's required to support health monitoring can be generated as a result of: The primary focus of health monitoring is to quickly indicate whether the system is running. Want to write better code? And it can generate reports, graphs, and charts to provide a historical view of the data that can help identify long-term trends. For example, at the application framework level, a task might be identified by a thread ID. To examine system usage, an operator typically needs to see information that includes: An operator should also be able to generate graphs. Note that in some cases, the raw instrumentation data can be provided to the alerting system. If you save captured data, store it securely. Remember that any number of devices might raise events, so the schema should not depend on the device type. (It fails to respond to a consecutive series of pings, for example.) APM is a big part of the DevOps movement. Record and capture the details of exceptions carefully. This might involve parsing logs that third-party services have generated. System health can be highlighted through a traffic-light system: A comprehensive health-monitoring system enables an operator to drill down through the system to view the health status of subsystems and components. To provide application specific monitoring events requires extreme detailed understanding how the application is working, this knowledge is usually only available to the application vendor and to application support staff at customers site. Dashboards can be organized hierarchically. 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. In a system that spans multiple datacenters, it might be useful to first collect, consolidate, and store data on a region-by-region basis, and then aggregate the regional data into a single central system. If there is a high volume of events, you can use an event hub to dispatch the data to different compute resources for processing and storage. The SteelCentral AppResponse, AppInternals and Portal are all required to get a holistic view that you get through many other products. Much of the analysis work consists of aggregating performance data by user request type and/or the subsystem or service to which each request is sent. Usage tracking can be performed at a relatively high level. Nastel provides another out of the box solution for deep APM analytics and discovery. Diagnosis requires the ability to determine the cause of faults or unexpected behavior, including performing root cause analysis. 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. A disk with an I/O rate that's approaching its maximum capacity over an extended period (a hot disk) can be highlighted in red.
