How to get disk usage in Vector host_metrics


I’ve setup a cassandra v4.1.2 cluster using k8ssandra-operator v1.8.0.

I’ve been following the monitoring docs here: Apache Cassandra® metrics endpoints | K8ssandra, Apache Cassandra on Kubernetes

With MCAC disabled and vector enabled, I’m getting lots of fun metrics as I expect. However, when I look through the host metrics at something like host_filesystem_used_bytes, I’m not getting any metrics for /var/lib/cassandra.

I’m guessing this is because Vector is running the in server-system-logger container which does not have the /var/lib/cassandra volume instead of the cassandra container.

What am I missing that would allow me to report metrics for the /var/lib/cassandra volume in the cassandra container?

Thank You
