Rules of alerts

Reading Time: < 1 minute

When to use

Alert rules are needed to automatically detect degradations and trigger a controlled response process.

What can be customized

  • Metric and comparator (above/below).
  • Thresholds warning and critical.
  • cooldownSeconds for noise control.
  • Dimension filter (JSON) for targeting specific interface, mount, vhost, etc.
  • Notification channels and target user.
  • Grouping rules in Alert Groups.

Steps

  1. Create a rule group (optional) if a shared policy is required.
  2. Create a rule: cluster, metric, comparator, thresholds, cooldown.
  3. Add channels and, if necessary, target user.
  4. Save the rule and check it in the general list.

Feature for processes

Favorites from Processes automatically become process-specific metric sources in the rule builder.

What to check

  • Rule applied to correct cluster and metric.
  • Notification channels are active and verified.
  • During a test violation, an incident of expected severity is formed.
