Apache Tomcat is an open-source usage of the Java Servlet, JavaServer Pages, Java Expression Language and WebSocket innovations. Tomcat gives a "unadulterated Java" HTTP web worker climate in which Java code can run.

 

Step 1: Enable Tomcat Plugin in Telegraf


By default telegraf we have got the telegraf.d directory on /etc/telegraf/telegraf.d in this path, You need to create a tomcat.conf configuration file and add the following nginx plugin syntax by following the given command.

 

©sudo vim /etc/telegraf/telegraf.d/tomcat.conf

Paste the given code to enable the tomcat plugin in telegraf.

# Gather metrics from the Tomcat server status page.
[[inputs.tomcat]]
  ## URL of the Tomcat server status
  # url = "http://127.0.0.1:8080/manager/status/all?XML=true"

  ## HTTP Basic Auth Credentials
  # username = "tomcat"
  # password = "s3cret"

  ## Request timeout
  # timeout = "5s"

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

Here you can uncomments the other parameter to use the username and password for Tomcat monitoring user as per your requirement, Save and exit from the vim text editor.


Step 2: Restart the Telegraf


You need to restart the Telegraf service to get new changes for Tomcat metric in prometheus, Use the following command for the same.

©©©sudo systemctl restart telegraf


Conclusion

We have successfully integrate tomcat with Telegraf in our Ubuntu 18.04 server.
