Weblogicbeat - Weblogic Monitoring with ELK

I had a previous entry about the configuration of logstash to capture the diagnostic, out, log, access, and garbage collector logs http://carlgira.blogspot.com/2017/09/logstash-configuration-for-weblogic.html . The idea of this entry is to explain a tool i just build to monitor a weblogic server using a custom beat of ELK (elasticsearh, logstash, kibana)

The tool is able to capture information about:

• Server state and health
• Memory use
• Threads status
• Datasource health and statistics
• Applications health and statistics

This information is sent to elasticsearch and kibana for metric visualization.

Configuration

- Download the tool from the releases link https://github.com/carlgira/weblogicbeat/releases

- Edit the file weblogicbeat.yml with your configuration.

Sample configuration file

weblogicbeat:
  period: 60s
  host: http://localhost:7001
  username: weblogic
  password: welcome1
  servername: server1
  datasources: ["EssDS", "EDNDataSource"]
  applications: ["ESSAPP", "sample-app"]

• period: How often an event is sent to the output
• host: Admin host and port
• username: Weblogic admin user
• password: Weblogic admin password
• servernam: Name of the server to monitor
• datasources: Array of datasources to monitor
• applications: Array of applications to monitor

- Run the tool

./weblogicbeat

Kibana

After starting weblogicbeat all the information should be arriving to kibana (remember to create an index with the name "weblogicbeat*") I create a set of visualizations and one dashboard to show all the metrics about weblogic. 

You can download the file https://github.com/carlgira/weblogicbeat/blob/master/kibana-weblogic-dashboard-export.json and import it to kibana. (follow instructions here https://www.elastic.co/guide/en/kibana/current/managing-saved-objects.html

Compilation

If you prefer to compile your own version you can go to the github repo and follow the README instructions. (or change it as you want). https://github.com/carlgira/weblogicbeat
