Autoscale metrics have stopped displaying

Question

Autoscale metrics have stopped displaying

Peter Oxenham 5

We have a dashboard chart that has been showing the autoscale metrics of Observed Capacity (Max) but that stopped displaying any data recently.

Another chart with the following metrics also shows no data now.

Metric Threshold (Avg), plan-app-prod-ausae-01-Autoscale-139

Observed Metric Value (Avg), plan-app-prod-ausae-01-Autoscale-139

Hello Peter Oxenham

Follow-up questions to help troubleshoot further

• Which resource type are you autoscaling (VMSS, App Service Plan, Cloud Service, etc.)?

• When exactly did the data disappear? Did you change any autoscale rules or dashboards around that time?

• If you open Metrics Explorer manually (not the dashboard), do these metrics show data?

• What time range and aggregation did you select in your chart?

• Can you share the resource ID of the Autoscale settings object?

Peter Oxenham hi & thx for join me here at Q&A portal,

Peter usually this means the autoscale setting metric stream changed or stopped emitting, not that autoscale itself is broken. those metrics are tied to the autoscale rule resource/name like plan-app-prod-ausae-01-Autoscale-139, so if the autoscale setting was edited, recreated, renamed, moved, or regenerated by IaC, the old dashboard chart can point to a dead metric dimension.

whether autoscale is still enabled and whether scale history still shows decisions. if scale history works, recreate the dashboard tiles from the current autoscale setting instead of the old metric reference.

Is the metric namespace/resource in Metrics Explorer coz autoscale metrics are under the autoscale setting, not always the App Service Plan itself.

if no autoscale metrics appear at all but scale still runs, open Azure Monitor ешслуе with resource ID, autoscale setting name, timestamp when it stopped, and examples of missing metrics.

Old dashboard likely points to stale autoscale metric series, rebuild tile from current autoscale setting

Hi Alex,

You are correct that the autoscale is working fine. It's the metrics that have stopped working. The autoscale instance hasn't changed so that is not the issue.

When I go into the autoscale settings and view the run history, that is also showing nothing.

Microsoft are looking into this now, so if they find the problem I'll make sure to post here for everyone else's benefit.

Peter
