Elastic APM Tool for Application Performance Monitoring

#Introduction

Elastic APM helps you monitor overall application health and performance.

Prerequisites

• Host OS: Ubuntu 21.04
• Installed Docker and Docker-compose
• elastic-apm-agent Java agent can be downloaded from here.

Elastic APM Tool

How to integrate the application with APM tool: elasticsearch, kibana, and apm-server

We will create a docker-compose file with the content below:

nano docker-compose.yml

The content file as below:

version: '3'
services:
      elasticsearch:
        image: docker.elastic.co/elasticsearch/elasticsearch:6.6.1
        ports:
          - "9200:9200"
      kibana:
        image: docker.elastic.co/kibana/kibana:6.6.1
        ports:
          - "5601:5601"
        depends_on:
          - elasticsearch
      apm-server:
          image: docker.elastic.co/apm/apm-server:6.6.1
          environment:
            - output.elasticsearch.hosts=["elasticsearch:9200"]
          ports:
            - "8200:8200"
          depends_on:
            - elasticsearch

Save and close that file.

Running the APM tool

docker-compose up -d

The result is the picture below:

Now, We will start the application with the javaagent and point to apm-server URL

java -javaagent:/<path-to-jar>/elastic-apm-agent-<version>.jar \
     -Delastic.apm.service_name=my-application \
     -Delastic.apm.server_url=http://localhost:8200 \
     -Delastic.apm.secret_token= \
     -Delastic.apm.application_packages=<base package> \
     -jar <jar name>.jar

Note: apm.application_packages → package where the main class is present

Configuration steps on Kibana

• Goto: http://localhost:5601 (http://localhost:5601/)
• Click on Add APM
• Scroll down and click on Check APM Server Status
• Scroll down and click on Check agent status
• Click on Load Kibana objects
• Launch APM

APM is now ready and integrated with the service.
