An alert rule monitors a deployment metric against a defined condition. When the condition is met for long enough, the rule transitions to firing and sends notifications through the attached contact points.
You need at least one contact point before creating an alert rule. Set one up first if you haven’t already.

​
Create an alert rule

1

Navigate to Alert Rules

In the sidebar, go to Alerting. You’ll see all alerts across your deployments. Click Add Alert to create a new rule.Alerts dashboard

Fill in Meta Data

Provide a Name for the alert rule. Optionally add Tags (up to 60 characters each) to help categorise and filter rules, and a Description for additional context.Add Alert Rule: Meta Data section

Select a deployment

In the Resource Details section, the Type is set to Deployment. Use the Resource Name dropdown to search for and select the deployment you want to monitor.Resource Details: select deployment

Configure Alert Condition Setup

In the Alert Condition Setup section:
  • Condition: Select a monitoring condition (e.g., High 4xx Error Rate). The available conditions are filtered by your deployment’s model type.
  • Parameters: Fill in the condition’s parameters such as thresholds, exclusion patterns, and evaluation window. Each field shows its unit, valid range, and a description.
  • Severity: Choose Critical (immediate attention required) or Warning (needs monitoring).
  • Contact Point: Select the contact points to notify when this rule fires. At least one contact point is required to activate the alert; you can add up to 5.
  • Evaluate every: How often Grafana evaluates the rule (e.g., 5m).
  • Pending Period: How long the condition must be continuously true before the alert transitions from pending to firing. Use this to suppress noise from transient spikes. Alert Condition Setup

Create the alert rule

Click Create Alert Rule. The rule is provisioned in Grafana and begins evaluating on the next interval.

​
Alert Details Page

Click any alert rule in the list to open its detail page. The page shows:
  • General Details: Severity, deployment, alert condition, threshold, and current value
  • Contact Points: The notification channels attached to this rule.
  • Meta Details: Creator, name, and description
  • Alert State panel: Current state, last evaluation time, evaluation interval, and pending period

Alert states

​
Mute an alert rule

Muting suppresses notifications for a rule without deleting it. A muted rule continues to evaluate and its state is still visible in the UI, but no notifications are sent. To mute a rule, open the alert rule detail page and click Mute. To resume notifications, click Unmute.

​
Edit an alert rule

Open the rule, make changes, and save. A confirmation modal shows the full diff of your changes before they are applied. The following fields can be updated after creation: description, parameters, severity, evaluation interval, pending period, contact points, tags, and enabled state.
The condition and deployment of an existing rule cannot be changed. To monitor a different metric or deployment, create a new rule.

​
Delete an alert rule

Open the rule, click the ⋮ menu, and select Delete. This removes the rule from Simplismart.
