Monitoring Performance Tool for Manager Health

JetPatch is always ready to show the latest performance monitoring and previous data on 3rd party library JetPatch utilizes -  Java Melody. This module provides health graphs on various KPI: CPU, memory.

  1. Login to JetPatch
  2. Go to: <SERVER-URL>/vmanage-server/monitoring  

  3. Select Week / Month to check performance and monitoring statistics:

  4. Checked used Memory: Memory allocation behaviour should be 'chainsaw' pattern- memory increases and reduces on a timely manner.

  5. Check CPU (‘CPU %’)  graph, validate the overall CPU shoulnd not be constantly above 70%mceclip1.png

  6.  Check threads (‘Active Threads’) graph, make sure that the thread allocation graph shows increase and decrease in the active threads (ranges should be between 40-160) mceclip2.png

  7. Check threads (‘Active jdbc connection’) graph,  make sure the graph is not constantly trending-up without any connections deallocations. (ranges should be between 20-50) mceclip3.png

Configuring a Custom HPROF (Java Heap Dump) Location

  1. Set the Custom Path

    • Open /usr/share/tomcat/default/conf/intigua.properties.
    • Add or update the line:
       
      jvm.heap.dump.location=/javaheap/log
    • Make sure /javaheap is an existing mount point. The /javaheap/log directory will be automatically created if it doesn’t exist.

  2. Verify Disk Space

    • Confirm that the partition hosting /javaheap/log has ample space (at least twice the server’s total memory).

  3. Restart Tomcat

    • Apply the changes by restarting the Tomcat service:
       
      service tomcat restart

Tip: The default installation directory for logs is /usr/share/tomcat/default. Always ensure sufficient disk space for large heap dumps. Also, make sure you grant read permissions so non-root accounts can download the heap file:

chmod a+r /javaheap/log/tomcat-java-heap.hprof
