Step 1 – Install Datadog Agent in Centos OR Ubuntu OR Windows

Step 2 – Install Apache HTTPD server in Ubuntu OR Centos/Redhat OR Windows

Step 3 – Click on the Integrations using Left bar Navigations as shown below

Step 4 – Enable mod_status & ExtendedStatus in Apache

Step 5 – Enable Datadog Apache Integration configuration to start collecting your Apache metrics.

$ cd /etc/datadog-agent/conf.d/apache.d/
$ sudo cp conf.yaml.example conf.yaml
$ sudo vi conf.yaml (CHECK IMAGE BELOW)
$ sudo service datadog-agent restart [UBUNTU]
$ sudo systemctl restart datadog-agent [Centos and Ubuntu]

$ watch curl http://65.1.107.190/ [ GENERATE FAKE LOAD ON APACHE SERVER ]

Step 6 – How to make sure if Datadog Agent is monitoring Apache

$ datadog-agent configcheck | grep apache -A 5 -B 5

=== apache check ===
Configuration provider: file
Configuration source: file:/etc/datadog-agent/conf.d/apache.d/conf.yaml
Config for instance ID: apache:9ad92079e09f96b4
apache_status_url: http://localhost/server-status?auto
disable_generic_tags: true
~

$ datadog-agent status | grep apache -B 5 -A 15
