Elastic APM Tool for Application Performance Monitoring

#Introduction

Elastic APM helps you monitor overall application health and performance. It is part of the Elastic Stack, which includes Elasticsearch, Logstash, and Kibana.

Elastic APM allows you to track and analyze the performance metrics of your applications, identify bottlenecks, and troubleshoot issues.

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.
