Apache Tomcat monitoring with Netdata

Presents memory utilization of tomcat containers.

Charts:

    • accesses

  2. Volume in KB/s

    • volume

  3. Threads

    • current
    • busy

  4. JVM Free Memory in MB

    • jvm

Configuration

Edit the python.d/tomcat.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/tomcat.conf

localhost:
  name : 'local'
  url  : 'http://127.0.0.1:8080/manager/status?XML=true'
  user : 'tomcat_username'
  pass : 'secret_tomcat_password'

Without configuration, module attempts to connect to http://localhost:8080/manager/status?XML=true, without any credentials. So it will probably fail.
