If you monitor Podman hosts using the mk_podman agent plugin, you must re-deploy the updated plugin to all monitored hosts after upgrading. Run the usual deployment command or procedure on each host to ensure the new version is installed.
The mk_podman agent plugin now supports configuring the connection method used to communicate with the Podman daemon. Users can choose between the REST API (default) and the Podman CLI.
Re-deploy the updated plugin on all hosts; otherwise, monitoring may break if the host lacks the selected connection method. In particular, hosts where only the CLI is available and the REST API is not (or vice versa) may stop updating monitoring data until the connection method is configured correctly.
After re-deployment, verify and adjust the connection method in the agent plugin ruleset under Podman hosts and containers (Linux) > Connection method to match the available connection method on each host. This ensures continuous monitoring of Podman hosts and containers.
