This template collects server resource information from an Apache Tomcat server by retrieving status information from the Tomcat status page.
Credentials: User with manager role:
Tomcat users and roles can be configured in tomcat-users.xml file. Example: <role rolename="manager"/> <user username="user" password="pass" roles="manager"/>
Note:You need to set thresholds for counters according to your environment. It is recommended to monitor counters for some length of time to understand potential value ranges and then set the thresholds accordingly. For more information, seehttp://knowledgebase.solarwinds.com/kb/questions/2415.
Note: By default all components use port 8080. If your Tomcat server uses another port, you should manually change the Port Number field in all components.
This monitor returns the total amount of memory currently allocated to the Java Virtual Machine heap space. This value should be as low as possible. You should set thresholds according to yourTomcat Max Memory value. If the returned value is near the Tomcat Max Memory value or you received OutOfMemoryErrorerrors, you may need to increase the heap size. More information can be found here: http://javarevisited.blogspot.com/2011/05/java-heap-space-memory-size-jvm.html.
