Overview

In order to make proper decisions as to whether one site should be made active over another, the ability for a particular site to process messaging needs to be ascertained.

Manually checking site health

In order to manually check the health of a site, the operator can run the sdnc.monitor script from the Kubernetes master in the site they are concerned with:

ubuntu@k8s-s2-master:~/oom/kubernetes/sdnc/resources/geo/bin$ ./sdnc.monitor
healthy
ubuntu@k8s-s2-master:~/oom/kubernetes/sdnc/resources/geo/bin$

This version of the script is actually a wrapper that utilizes kubectl to remotely access the PROM pod in order to run the sdnc.monitor script that actually performs the health checks on components in the site.

Alternatively, the sdnc.monitor script available in the PROM pod can be run directly:

root@dev-prom-6485f566fb-hdhzs:/path/to/scripts# ./sdnc.monitor
healthy
root@dev-prom-6485f566fb-hdhzs:/path/to/scripts#
