Common alerts to share?

[samber]

Hi there 👋

@sfarwassim just opened an issue on samber/awesome-prometheus-alerts to request contributions.

Do you have nice Prometheus alerts to share, for NATS monitoring?

Something like this?

groups:
- name: NATSAlerts
  rules:
  - alert: HighConnectionCount
    expr: gnatsd_varz_connections > 100
    for: 1m
    labels:
      severity: warning
    annotations:
      summary: "High number of NATS connections ({{ $value }})"
      description: "The number of NATS connections is greater than 100 for {{ $labels.instance }}"

  - alert: HighPendingBytes
    expr: gnatsd_connz_pending_bytes > 100000
    for: 5m
    labels:
      severity: warning
    annotations:
      summary: "High number of NATS pending bytes ({{ $value }})"
      description: "The number of NATS pending bytes is greater than 100000 for {{ $labels.instance }}"

  - alert: HighSubscriptionsCount
    expr: gnatsd_connz_subscriptions > 50
    for: 5m
    labels:
      severity: warning
    annotations:
      summary: "High number of NATS subscriptions ({{ $value }})"
      description: "The number of NATS subscriptions is greater than 50 for {{ $labels.instance }}"

  - alert: HighRoutesCount
    expr: gnatsd_routez_num_routes > 10
    for: 5m
    labels:
      severity: warning
    annotations:
      summary: "High number of NATS routes ({{ $value }})"
      description: "The number of NATS routes is greater than 10 for {{ $labels.instance }}"
