If any deadlocked threads are found, you will see a new Deadlock tab with more information about what is causing the deadlocks. To see real-time data related to the Tomcat metrics you are monitoring, you can view the Catalina and java.

Like Tomcat Manager, JConsole collects data from the MBean server, but provides a simpler interface for finding the metrics you need. However, it does not include support for graphing Tomcat metrics. JavaMelody is an open source monitoring platform that offers more fine-grained timeseries visualizations for Tomcat and JVM metrics. You can change the time period for all graphs, and select an individual graph to get a more detailed look into any server, virtual machine, or database activity metric.

If you click on any chart, you will be able to see the mean, maximum, and 95th percentile values for the chosen metric. The monitoring page also includes information about system and HTTP request errors. JavaMelody aggregates similar errors together so you can see how many of each type are generated.

For the selected time frame, you can see the percentage of CPU time spent generating each type of error. In the example above, the Tomcat server generated errors with a HTTP response code Internal Server Error 99 percent of the time it was running over the past week. By default, Tomcat access logs use the Common Log Format , and record all requests processed by the server. This pattern code logs the time taken to process the request in milliseconds—an important metric to track for understanding how well Tomcat processes individual requests.

Tomcat also generates server logs by default, and uses its own implementation of the java. Server logs show information related to the Tomcat JVM and Catalina server, including out-of-memory OOM errors and deployment activity, as seen in the example below:. Tomcat writes server logs to the console and to a Catalina log file e.

Handlers are Java components that process incoming log messages and format their output, with formatters for logging to a file FileHandler or to your console ConsoleHandler. While handler properties manage your Tomcat logs overall, facility properties enable you to manage configurations for each deployed application, including Tomcat Manager.

For example, to adjust the log levels for Tomcat Manager, you can edit the following handler and facility properties:. Tomcat also provides low-level diagnostic information about requests and server activity in its access and server logs. Each of these platforms offers different capabilities for monitoring Tomcat, but none of them enable you to see the full picture when an issue occurs.

Monitoring ID: monitoring. Author : Emeric Vernat evernat at free. Release notes Since 1. If that's not enough, some RRD files of graphs for http requests will now be automatically deleted everyday at midnight to limit the disk space used by RRD files under 20 MB. You may configure that limit with the javamelody parameter max-rrd-disk-usage-mb 20 by default.

And old statistics and graphs are automatically deleted like before. See doc. Look further to display the remote user in the current requests. And the real case 3 on the investigation of why dozen of users are working extra-hours and of other issues. Note that the link on "Monitoring of memory, cpu, http requests and more in Jenkins master.

And the link on "You can also view the monitoring of builds, build queue and Jenkins nodes. In this article. Azure Metrics Explorer. A free tool in the Azure portal to help you monitor the performance and health of your Azure Analysis Services servers.

Azure Diagnostics. Use Azure diagnostic logs to monitor and log Azure Analysis Services server performance. SQL Server Profiler. Tracks engine process events. They also have a unique alerting system that escalates internal awareness as unanswered problems prolong. RapidSpike, another monitoring tool that monitors API endpoints.

Australian-based Agilityworks provides a platform for continuous API testing. In addition to verifying API behavior, their reporting provides insights into important metrics.

Agilityworks appears to be more designed to aid continuous deployment than as a constant heart rate monitor. Checkly is another service that performs full API monitoring, including configurable requests, assertions, and importers for cURL and Swagger. They also provide site transaction monitoring. Bearer is an API monitoring tool that can be directly embedded into applications, to provide automated tailored monitoring and alerting.

Bearer is available for Node. Site Docs Sandbox. Lightstep delivers unified observability, with visibility across multi-layered architectures, enabling teams to detect and resolve regressions quickly, regardless of system scale or complexity. They help companies like InVision, Lyft, and Digital Ocean gain complete visibility into their complex systems. Lightstep was founded by the creator of Dapper and co-founder of OpenTracing and OpenTelemetry, and currently, helping thousands of developers improve how they build and operate microservices at scale.

The plug-and-play solutions are great for many circumstances, but larger enterprises may prefer more holistic IT management monitoring and alert systems. For example, solutions offered by PagerDuty , Site24x7 , Catchpoint , and many others provide a means to track API endpoints in addition to websites, web services, and servers. Capterra has done our work in comparing 10 of those here. In a post on the Runscope blog , Twain Taylor acknowledges that the modern software monitoring toolkit is extremely multi-faced.

Not only must QA practitioners consider monitoring their APIs, but infrastructure, application performance analysis, log analysis, container specific metrics, and more must be tracked and analyzed. Other organizations may prefer a more DIY approach to API monitoring; using open-source tooling and greenfield development could reduce overhead.

Monitoring is just part of the many aspects that make up quality API practice. Instilling an API monitoring strategy can help avoid downtime and ensure teams respond well to issues.
