Alert Management Skill

Alert Management Skill

Use this skill to list, inspect, create, delete, enable, and disable Coralogix alert definitions using the cx alerts CLI commands.

CLI Commands

Output format: append -o json or -o agents to list, get, and create commands for machine-readable output.

Multi-profile: use -p <profile> (repeatable) to target multiple profiles simultaneously.

Alert Types Reference

Coralogix supports 12 alert types:

Priority Levels

Always ask the user what priority to use when creating alerts:

Create Workflow

1. Ask the user what they want to alert on (logs, metrics, traces)
2. Ask for priority (P1–P5)
3. Build the JSON payload with alertDefProperties - use the API wire format (see references/​alert-schemas.md for all enum values)
4. Tip: use cx alerts get <existing-id> -o json to get a working template, modify it, and pipe into create
5. Create using: echo '<json>' | cx alerts create or cx alerts create --from-file alert.json
6. Verify with cx alerts list --name "<alert name>"

Important structural note: The type field is a string enum (e.g. "ALERT_DEF_TYPE_LOGS_THRESHOLD"), and the alert type config (e.g. "logsThreshold": {...}) is a sibling field at the same level - NOT nested inside type.

Example: Logs Threshold Alert

{
  "alertDefProperties": {
    "name": "High Error Rate",
    "description": "Alert when error logs exceed threshold",
    "priority": "ALERT_DEF_PRIORITY_P2",
    "type": "ALERT_DEF_TYPE_LOGS_THRESHOLD",
    "enabled": true,
    "logsThreshold": {
      "logsFilter": {
        "simpleFilter": {
          "luceneQuery": "severity:ERROR",
          "labelFilters": {
            "applicationName": [
              { "operation": "LOG_FILTER_OPERATION_TYPE_IS_OR_UNSPECIFIED", "value": "my-app" }
            ]
          }
        }
      },
      "rules": [{
        "condition": {
          "conditionType": "LOGS_THRESHOLD_CONDITION_TYPE_MORE_THAN_OR_UNSPECIFIED",
          "threshold": 100,
          "timeWindow": {
            "logsTimeWindowSpecificValue": "LOGS_TIME_WINDOW_VALUE_MINUTES_5_OR_UNSPECIFIED"
          }
        }
      }]
    }
  }
}

Example: Metric Threshold Alert

{
  "alertDefProperties": {
    "name": "CPU Usage Critical",
    "priority": "ALERT_DEF_PRIORITY_P1",
    "type": "ALERT_DEF_TYPE_METRIC_THRESHOLD",
    "enabled": true,
    "metricThreshold": {
      "metricFilter": { "promql": "avg(cpu_usage_percent)" },
      "rules": [{
        "condition": {
          "conditionType": "METRIC_THRESHOLD_CONDITION_TYPE_MORE_THAN_OR_UNSPECIFIED",
          "threshold": 90,
          "ofTheLast": { "dynamicDuration": "5m" },
          "forOverPct": 100
        }
      }]
    }
  }
}

Example: Logs Immediate Alert

{
  "alertDefProperties": {
    "name": "OOM Killer Detected",
    "description": "Alert immediately when OOM killer runs",
    "priority": "ALERT_DEF_PRIORITY_P1",
    "type": "ALERT_DEF_TYPE_LOGS_IMMEDIATE_OR_UNSPECIFIED",
    "enabled": true,
    "logsImmediate": {
      "logsFilter": {
        "simpleFilter": {
          "luceneQuery": "\"Out of memory\" OR \"OOM\"",
          "labelFilters": {}
        }
      }
    }
  }
}

Investigation Workflow

Find firing alerts

# List all alerts and look for ALERTING status
cx alerts list -o json | jq '.[] | select(.status == "ALERTING")'

# Filter by name
cx alerts list --name "error"

Inspect a specific alert

cx alerts get <alert-id>
cx alerts get <alert-id> -o json

Disable a noisy alert (temporary mute)

cx alerts disable <alert-id>
# Later, re-enable:
cx alerts enable <alert-id>

Suppression Rules

Manage alert suppression rules that mute alerts during maintenance windows or known noisy periods.

# List suppression rules
cx alerts suppression-rules list -o json

# Create from template
cx alerts suppression-rules get <existing-id> -o json > suppression-rule.json
# Edit suppression-rule.json
cx alerts suppression-rules create --from-file suppression-rule.json

Key Principles

• Always ask for priority (P1–P5) when creating alerts - never assume
• Use --name filter for large accounts with many alerts
• Use -o json with jq for filtering and transformation
• Use --from-file - to pipe JSON from stdin when constructing alerts programmatically
• Verify after create - always list or get the alert after creation to confirm
• Disable, don't delete - prefer disabling alerts over deletion for auditability
