Azure Monitor
EvoHub receives Azure Monitor alerts through a Webhook action in an action group, using the common alert schema. A fired alert opens an EvoHub alert, and the resolved notification resolves it.
Set it up
Create the integration
In EvoHub, go to On-Call → Integrations → + Add Integration, choose Azure Monitor, pick an Escalation Policy and click Create Integration. Copy the Webhook URL.
Warning
Enable common alert schema must be Yes. EvoHub refuses any other payload with 400 INVALID_SCHEMA and the message "enable 'common alert schema' on the Azure action group".
Turn on auto-resolve
No extra setup is needed. When Azure Monitor sends the alert with monitorCondition: Resolved, EvoHub resolves the matching alert. If an alert rule never sends a resolved notification, its alerts stay open until someone resolves them in EvoHub.
What EvoHub reads
EvoHub reads the data.essentials part of the common alert schema:
| EvoHub alert | Taken from |
|---|---|
| Title | alertRule (or "Azure Monitor Alert"). |
| Description | description. A metric alert without one says what crossed what, from alertContext, for example "Percentage CPU is 31.1 (GreaterThan 25)". |
| Labels | severity (as Azure sends it, for example Sev1) and resource, the first of configurationItems, plus the action group's customProperties. |
| Link | investigationLink when Azure sends it, else a log search alert's link to its results. It opens from the alert. |
| Values | A metric alert's metric, metric_value and threshold. |
| Fingerprint | alertId (or, if it is missing, the alert rule name). |
Severity
| Azure severity | EvoHub severity |
|---|---|
| Sev0 | critical |
| Sev1 | high |
| Sev2 | medium |
| Sev3 | low |
| Sev4 | info |
| anything else | medium |
Resolve and deduplication
monitorCondition: Resolvedresolves the open alert with the samealertId. Any other condition, such as Fired, opens an alert.- Another notification for the same
alertIdwhile its alert is open is recorded as Retriggered.
Troubleshooting
400 INVALID_SCHEMA: the action group sends the legacy schema. Turn on Enable common alert schema for the webhook action.401 INVALID_KEY: the URL's key is wrong or the integration is disabled. Copy the Webhook URL again from the integration.- Nothing arrives: check that the action group is attached to the alert rule and that the webhook action is the one with your URL.
