|
## Alerting stack configuration and Managed VictoriaMetrics
|
|
|
|
Managed VictoriaMetrics supports configuring alerting rules and notifications through Alertmanager and internal vmalert.
|
|
|
|
## Configure Alertmanager
|
|
|
|
Managed VictoriaMetrics supports Alertmanager with standard [configuration](https://prometheus.io/docs/alerting/latest/configuration/).
|
|
Configuration menu located at `deployment` page under `Alertmanager` section.

## Configure alerting rules
|
|
|
|
Alerting and recording rules could be configured via API calls.
|
|
|
|
### Managed VictoriaMetrics rules API
|
|
|
|
Managed VictoriaMetrics has following APIs for rules:
|
|
|
|
* POST: `/api/v1/deployments/{deploymentId}/rule-sets/files/{fileName}`
|
|
* DELETE `/api/v1/deployments/{deploymentId}/rule-sets/files/{fileName}`
|
|
|
|
OpenAPI [link](https://cloud.victoriametrics.com/api-docs)
|
|
|
|
### rules creation with API
|
|
|
|
Let's create two example rules for deployment in `testing-rules.yaml`
|
|
|
|
```yaml
|
|
groups:
|
|
- name: examples
|
|
concurrency: 2
|
|
interval: 10s
|
|
rules:
|
|
- alert: never-firing
|
|
expr: foobar > 0
|
|
for: 30s
|
|
labels:
|
|
severity: warning
|
|
annotations:
|
|
summary: empty result rule
|
|
- alert: always-firing
|
|
expr: vector(1) > 0
|
|
for: 30s
|
|
labels:
|
|
severity: critical
|
|
annotations:
|
|
summary: "rule must be always at firing state"
|
|
```
|
|
|
|
Upload rules to the Managed VictoriaMetrics using the following command:
|
|
|
|
```sh
|
|
curl https://https://cloud.victoriametrics.com/api/v1/deployments/DEPLOYMENT_ID/rule-sets/files/testing-rules -v -H 'X-VM-Cloud-Access: CLOUD_API_TOKEN' -XPOST --data-binary '@testing-rules.yaml'
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
### rules execution state
|
|
|
|
The state of created rules is located in the rules section for Deployment:
|

|
|
|
|
### debug
|
|
|
|
It's possible to debug the alerting stack with logs for vmalert and alertmanager, which are accessible in the Logs section of the deployment.
|
|

|
|
|
|
### cloud monitoring
|
|
|
|
Alertmanager and vmalert errors are tracked by internal cloud monitoring system.
|
|
Deployment `Alerts` section has information for active incidents and incident history log.
