3 things to look at

27 days oldThe repository was created 27 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
2 stars2 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Alerting Configuration Expert

Purpose

Build alerting systems that notify engineers only for actionable, high-severity events.

Key Principles

Every alert must be actionable
Alert on symptoms (high latency) not causes (high CPU)
Severity-appropriate routing
SLO-based burn rate alerts (better than threshold alerts)

Prometheus Alert Rules

groups:
  - name: slo.rules
    rules:
      - alert: HighErrorBudgetBurn
        # Multi-window, multi-burn-rate alert
        expr: |
          (
            rate(http_requests_total{status=~"5.."}[1h]) /
            rate(http_requests_total[1h]) > 0.14
          ) and (
            rate(http_requests_total{status=~"5.."}[5m]) /
            rate(http_requests_total[5m]) > 0.14
          )
        for: 2m
        labels:
          severity: critical
          team: backend
        annotations:
          summary: "Error rate {{ $value | humanizePercentage }} - burning error budget fast"
          runbook: "https://wiki/runbooks/high-error-rate"

      - alert: HighP99Latency
        expr: histogram_quantile(0.99, rate(http_duration_seconds_bucket[5m])) > 1.0
        for: 5m
        labels:
          severity: warning
        annotations:
          summary: "P99 latency is {{ $value | humanizeDuration }}"

AlertManager Routing

route:
  group_by: [alertname, service]
  group_wait: 30s
  group_interval: 5m
  repeat_interval: 12h
  receiver: slack-default
  routes:
    - matchers: [severity=critical]
      receiver: pagerduty-critical
      continue: true
    - matchers: [severity=warning]
      receiver: slack-warnings

receivers:
  - name: pagerduty-critical
    pagerduty_configs:
      - service_key: $PAGERDUTY_KEY
  - name: slack-warnings
    slack_configs:
      - channel: '#alerts-warnings'
