Tomcat Monitoring & Management


Apache Tomcat is the servlet container that is used in the official reference implementation of the Java Servlet and JavaServer Pages technologies. It is widely deployed by customers looking for a scalable open source Java application server.

The Hyperic engineering team has been actively working with Apache Tomcat both as end-users and developers since early 2000. The team has used this experience to help build a Tomcat management solution which helps organizations to safely deploy it into production without worrying about how they can manage it effectively. Hyperic is currently in use to manage, monitor and control some of the world's largest production Tomcat deployments.

Hyperic's extensive experience with high-performance Tomcat monitoring is derived from its use of Tomcat as a core component the Hyperic server. Throughout its involvement in the Tomcat community, Hyperic has worked with its customers and the community to ensure that HQ provides the most complete Tomcat management features available from any solution on the market.

Hyperic's Tomcat management plugin provides detailed information about the health and performance of the server as well as every webapp and connector deployed in it. This capability allows customers to gain a level of visibility into the resource consumption of both the server as well as every webapp without requiring instrumentation of your Tomcat or JVM.

Hyperic's SIGAR monitoring technology provides users with information on JVM performance which offers measurements of the Tomcat server from the operating system's point of view. The additional Tomcat monitoring capabilities provided by SIGAR have helped Hyperic customers gain the upper hand in managing large scale Tomcat implementations.

Hyperic's Tomcat management technology allows you to answer questions without any instrumentation of your environment such as:

  • Which of my webapps is consuming the most amount of CPU?
  • How much memory is the Tomcat JVM process actually taking up?

Hyperic's web based portal allows you to build personalized views of monitoring data which compare things like CPU consumption for your tomcat instance, the response time of every webapp, and the load average of the machine hosting the Tomcat server. These easy to use views provide insight into Tomcat performance which help identify problems and do capacity planning for large environments. Hyperic also provides real per-URL request response time monitoring which displays real performance data for each request serviced by your Tomcat webapps.

Hyperic also provides complete event management capabilities for all versions of Tomcat. Administrators can use Hyperic to collect information from Tomcat's logs and use it to generate alerts as well as track any exceptions reported to the log. Hyperic can also track Tomcat's configuration, allowing you to audit any changes into Tomcat's configurations and measure their impact on performance and availability.

Hyperic's Tomcat control capability is built to help operations teams perform corrective action on large clusters of Tomcat servers from a single web based interface. The Tomcat control feature allows you to perform immediate, scheduled, or alert-driven control operations on the server. It also allows users to perform per webapp control actions such as reload, deploy, and undeploy without affecting the availability of the server.
