Monitoring
The Monitoring tab shows resource-utilization graphs for the scale group's nodes. It is available when the group is Running or Scaling.
The graphs cover the same signals the elastic policy can scale on — primarily CPU, along with memory and disk utilization — so you can correlate scaling activity with load. Select a time range to widen or narrow the window.
Because the CPU metric (and any custom metric you publish) is what the elastic policy evaluates, use this tab to verify that:
- Utilization rises and falls as you expect under load.
- Scale-up happens after the metric stays above your threshold for the watch period.
- Scale-down happens after it falls below the lower threshold.
For the scaling actions that the metrics trigger, see the Audit Logs and Activity Timeline. To see the individual nodes being added and removed, see Node Details.
If the group is not scaling the way you expect, compare the Monitoring graph against your policy thresholds and watch period on the Scale Group Details tab. A threshold that is never crossed, or a watch period that is too long, are the most common reasons a group does not scale.
