If you are experiencing issues with a given Agent Check, use these commands for your OS to get more troubleshooting information:
Note: Replace <CHECK_NAME> in the examples below with any Agent check. For example: activemq, ceph, or elastic. Review an integration’s documentation to confirm the Agent check name.
Note: To temporarily disable a service check while troubleshooting, rename /conf.d/<CHECK_NAME>.d/conf.yaml to something other than the .yaml or .yml file extension, such as conf.yaml.disable.
Linux
To test an Agent check, run:
sudo -u dd-agent datadog-agent check <CHECK_NAME>
If you want to include rate metrics, add --check-rate to your command, for instance for Agent v6.x run:
sudo -u dd-agent datadog-agent check <CHECK_NAME> --check-rate
sudo -u dd-agent dd-agent check <CHECK_NAME>
Replace <CHECK_NAME> with any Agent check. For example: activemq, ceph, or elastic. Review an [integration’s documentation][4] to confirm the Agent check name.
If you want to include rate metrics, add --check-rate to your command, for instance for Agent v6.x run:
sudo -u dd-agent dd-agent check <CHECK_NAME> --check-rate
If your issue continues, reach out to the Datadog support team with a flare.
Windows
Run the following script from an elevated (run as admin) PowerShell command line, with the proper <CHECK_NAME>:
For Agent versions >= 6.12:
& "$env:ProgramFiles\Datadog\Datadog Agent\bin\agent.exe" check <CHECK_NAME>
For Agent versions <= 6.11:
& "$env:ProgramFiles\Datadog\Datadog Agent\embedded\agent.exe" check <CHECK_NAME>
The Agent install includes a file called shell.exe in your Program Files directory for the Datadog Agent. This file can be used to run Python within the Agent environment. Once your check (called <CHECK_NAME>) is written and you have the .py and .yaml files in their correct places, run the following in shell.exe:
from checks import run_check
run_check('<CHECK_NAME>')
This outputs any metrics or events that the check returns.
Run the following script from an elevated (run as admin) PowerShell command line, with the proper <CHECK_NAME>:
<INSTALL_DIR>/embedded/python.exe <INSTALL_DIR>agent/agent.py check <CHECK_NAME>
For example, to run the disk check:
& "$env:ProgramFiles\Datadog\Datadog Agent\embedded\python.exe" "$env:ProgramFiles\Datadog\Datadog Agent\agent\agent.py" check disk
Systemd
For systems using systemd, use journalctl to assist with debugging.
The following command shows the status of the Datadog Agent.
sudo systemctl status datadog-agent
If the Agent failed to start, and no further information is provided, use the following command to display all logs for the Datadog Agent service. If needed, use -r to print logs in reverse order.
sudo journalctl -u datadog-agent.service
The following command shows the status of the Datadog Agent.
sudo systemctl status dd-agent
If the Agent failed to start, and no further information is provided, use the following command to display all logs for the Datadog Agent service. If needed, use -r to print logs in reverse order.
