When to use
Create a cluster when you need to isolate a separate monitoring circuit: project, team, environment or client.
What to prepare
- The name of the cluster according to an understandable scheme (for example,
prod-euorclient-a-stage). - Base threshold
offlineThresholdSecondsto determine the server status. - Deciding which collectors and graphs the team needs at the start.
Steps in UI
- Open the Clusters section and create a new cluster.
- Go to the cluster card and set the offline threshold.
- Enable the required collectors: CPU, Memory, Disk I/O, Network, Filesystem, SSL.
- Choose a set of graphs for Live View and save the configuration.
What to check
- The cluster appeared in the list and opens without errors.
- Offline threshold settings, collectors and graphs are saved.
- From the cluster, transitions to Servers, Incidents and Audit are available.
Practice
Keep one cluster for one operational responsibility. This simplifies alerts, access and incident resolution.
