In the past week we’ve rolled out a bunch of updates to our Kubernetes cluster-monitoring stack.
Except for the updated compoments (see below) we have also added a couple of new features:
- Allow enabling of custom Grafana plugins through the cluster definition file. Want to use heatmaps, pie charts or more? This and more can be achieved through Grafana Plugins.
- Allow setting additionalServiceMonitors through the cluster definition file. This allows to have some generic
ServiceMonitorscrapers defined, next to the ones you deploy with your applications.
- (Optional) Deploy Grafana with persistent storage. When enabled, you can import and edit your dashboards (or data sources) directly via the Grafana UI without having to worry that it’ll disappear when Grafana restarts. Using
ConfigMapsto import dashboards and data sources is of course still supported too.
Get in touch if these sound interesting to enable!
