Linux systems that are configured to autoinstall packages may not be configured to autoreboot (it may be desirable to time this manually). This check enables alerts to be fired in the case where reboots are not performed in a timely manner.
Setup
The Reboot Required check is not included in the Datadog Agent package, so you need to install it.
Installation
For Agent v7.21+ / v6.21+, follow the instructions below to install the Reboot Required check on your host. See Use Community Integrations to install with the Docker Agent or earlier versions of the Agent.
Run the following command to install the Agent integration:
Make sure you create a dd-agent (user that runs the Datadog agent) writable directory for the agent, and used by this check. The default of /var/run/dd-agent is ideal. The snippet below should suffice.
The reboot_required check does not include any events.
Service Checks
