KernelCare is a live patching system that automatically applies security patches to Linux kernel vulnerabilities, with no reboots. It’s used on over 500,000 servers, and has been used to patch servers running for 6+ years for Dell, Zoom and other enterprise companies. It works with all major Linux distributions, such as RHEL, CentOS, Amazon Linux, and Ubuntu & interoperates with common vulnerability scanners, cloud monitoring tools & patch management solutions.
This integration allows you to forward the Kernelcare metrics through the Datadog Agent.
The Kernelcare check is not included in the Datadog Agent package, so you need to install it.
For Agent v7.21+ / v6.21+, follow the instructions below to install the Kernelcare 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:
datadog-agent integration install -t datadog-kernelcare==<INTEGRATION_VERSION>
Configure your integration similar to core integrations.
kernelcare.d/conf.yaml file, in the
conf.d/ folder at the root of your Agent’s configuration directory to start collecting your kernelcare performance data. See the sample kernelcare.d/conf.yaml for all available configuration options.
Run the Agent’s status subcommand and look for
kernelcare under the Checks section.
