How to enable process monitoring in data-dog agent

Open the datadog.yaml and uncomment the process_config section under that process_collection should be enabled as true

## @param process_collection - custom object - optional
## Specifies settings for collecting processes.
## @param enabled - boolean - optional - default: false
## Enables collection of information about running processes.
enabled: true

Save the file and restart the agent using command --> systemctl restart datadog-agent

  • Below command will give you the confirmation about the process monitoring enabled or not datadog-agent config | grep process_collection -B 5 -A 5


Write it down a step to collect apache metrices to datadog

Install apache
$ sudo apt update
$ sudo apt install apache2

Replace this file with your new content to post
$ vi /var/www/html/index.html

Restart the apache
$service apache2 restart

Validate using the below curl
$ watch curl http://localhost

  • Once installed and validated.. Install the apache integration in datadog UI

  • Then install mod_status and enable it
    By default above modules are enabled but validate once
    $ ls /etc/apache2/mods-enabled | grep status*

Ensure the status files are available using the below command
sudo /usr/sbin/a2enmod status

Even though mod_status module enabled we need to allow all incoming connecting to the apache server by allowing a grant permission under status.conf file and restart the apache server using the below commands
$ sudo systemctl restart apache2
$ sudo systemctl status apache2
$ curl http://server-ip/server-status
$ curl http://server-ip/server-status?refresh=5

  • Enable apache datadog integration using the below steps
    $ cd /etc/datadog-agent/conf.d/apache.d/
    $ sudo cp conf.yaml.example conf.yaml
    $ sudo vi conf.yaml -- Need to replace apache status url
    $ sudo service datadog-agent restart [UBUNTU]
    $ sudo systemctl restart datadog-agent [Centos and Ubuntu]

  • Use the below command to verify whether datadog agent configured correctly with apache
    $ datadog-agent configcheck | grep apache -A 5 -B 5

  • Finally install integration in the SaaS UI and verify the apache metrics in metric explorer, host.
