With the upcoming end-of-life (EOL) of MSR 3.1.x, Mirantis encourages you to upgrade to the latest supported version to ensure continued support and security updates.

Health check endpoints

MSR exposes several endpoints that you can use to assess whether or not an MSR replica is healthy:

• /_ping: Checks if the MSR replica is healthy, and returns a simple JSON response. This is useful for load balancing and other automated health check tasks.

• /nginx_status: Returns the number of connections handled by the NGINX MSR front end.

• /api/v0/meta/cluster_status: Returns detailed information about all MSR replicas.
