Reboot Required

Agent Check Agent Check

Supported OS: Linux


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.



To install the Reboot Required check on your host:

  1. Install the developer toolkit on any machine.
  2. Run ddev release build reboot_required to build the package.
  3. Download the Datadog Agent.
  4. Upload the build artifact to any host with an Agent and run datadog-agent integration install -w path/to/reboot_required/dist/<ARTIFACT_NAME>.whl.


To configure the Reboot Required check:

  1. Create a reboot_required.d/ folder in the conf.d/ folder at the root of your Agent’s directory.
  2. Create a conf.yaml file in the reboot_required.d/ folder previously created.
  3. Consult the sample reboot_required.yaml file and copy its content in the conf.yaml file. Minimum configuration should include:

        - reboot_signal_file: "/var/run/reboot-required"
  4. 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.

    sudo mkdir /var/run/dd-agent
    sudo chown dd-agent:dd-agent /var/run/dd-agent
  5. Restart the Agent.


Run the Agent’s status subcommand and look for reboot_required under the Checks section.

Data Collected


No metrics are collected.


The reboot_required check does not include any events.

Service Checks

To create alert conditions on these service checks in Datadog, select ‘Custom Check’ on the Create Monitor page, not ‘Integration’.


The check returns:

  • OK if the system does not require a reboot or for less than days_warning or days_critical.
  • WARNING if the system has required a reboot for longer than days_warning days.
  • CRITICAL if the system has required a reboot for longer than days_critical days.
