uptime-kuma	Manage Uptime Kuma monitoring via the Python API. Use when: (1) User asks to add, remove, or list monitors, (2) User asks about service uptime or monitoring status, (3) User asks to check what's being monitored, (4) User deploys a new service and needs monitoring added, (5) User mentions "uptime", "monitoring", "health check", or "uptime kuma". Uptime Kuma v2 running in Kubernetes, managed via uptime-kuma-api Python library.	Claude Code	1.0.0	2026-02-14

Uptime Kuma Monitoring Management

Overview

• URL: https://uptime.viktorbarzin.me
• Internal: uptime-kuma.uptime-kuma.svc.cluster.local:80
• Image: louislam/uptime-kuma:2
• Storage: NFS at /mnt/main/uptime-kuma -> /app/data
• API Library: uptime-kuma-api (pip, available via PYTHONPATH)
• Credentials: admin / (from UPTIME_KUMA_PASSWORD env var)

Python API Access

Connection Pattern

import os
from uptime_kuma_api import UptimeKumaApi, MonitorType

api = UptimeKumaApi('https://uptime.viktorbarzin.me')
api.login('admin', os.environ.get('UPTIME_KUMA_PASSWORD', ''))

# ... operations ...

api.disconnect()

Execution

python3 -c "
import os
from uptime_kuma_api import UptimeKumaApi, MonitorType
api = UptimeKumaApi('https://uptime.viktorbarzin.me')
api.login('admin', os.environ.get('UPTIME_KUMA_PASSWORD', ''))
# ... your code ...
api.disconnect()
"

Common Operations

List All Monitors

monitors = api.get_monitors()
for m in monitors:
    print(f'{m["id"]:3d} | {m["name"]:30s} | {m["type"]:15s} | interval={m["interval"]}s')

Add HTTP Monitor

api.add_monitor(
    type=MonitorType.HTTP,
    name="Service Name",
    url="http://service.namespace.svc.cluster.local",
    interval=120,
    maxretries=2,
)

Add PING Monitor

api.add_monitor(
    type=MonitorType.PING,
    name="Host Name",
    hostname="10.0.20.1",
    interval=30,
    maxretries=3,
)

Add PORT Monitor

api.add_monitor(
    type=MonitorType.PORT,
    name="Service Port",
    hostname="service.namespace.svc.cluster.local",
    port=8080,
    interval=120,
    maxretries=2,
)

Edit Monitor

api.edit_monitor(monitor_id, interval=120, maxretries=2)

Delete Monitor

api.delete_monitor(monitor_id)

Pause/Resume Monitor

api.pause_monitor(monitor_id)
api.resume_monitor(monitor_id)

Monitor Types

• MonitorType.HTTP — HTTP(S) endpoint check
• MonitorType.PING — ICMP ping
• MonitorType.PORT — TCP port check
• MonitorType.POSTGRES — PostgreSQL connection
• MonitorType.REDIS — Redis connection
• MonitorType.DNS — DNS resolution check

Tiered Monitoring System

Monitors use tiered intervals to balance responsiveness with resource usage:

Tier	Interval	Retries	Use For
1 - Critical	30s	3	Core infra (DNS, gateway, ingress, NFS, K8s API, auth, mail)
2 - Important	120s	2	Actively used services (Nextcloud, Immich, Vaultwarden, etc.)
3 - Standard	300s	1	Auxiliary/optional services (blog, games, tools)

Tier Assignment Guidelines

• Tier 1: If it goes down, multiple other services fail or the cluster is unreachable
• Tier 2: User-facing services that are actively used daily
• Tier 3: Nice-to-have services, tools, dashboards

When Adding a New Service

Match the tier to the service's DEFCON level from CLAUDE.md:

• DEFCON 1-2 → Tier 1 (30s)
• DEFCON 3-4 → Tier 2 (120s)
• DEFCON 5 → Tier 3 (300s)

Internal Service URL Pattern

Most K8s services follow: http://<service-name>.<namespace>.svc.cluster.local:<port>

Common port is 80. Exceptions:

• Homepage: port 3000
• Ollama: port 11434
• Loki: port 3100 (use /ready endpoint)
• Traefik dashboard: port 8080 (use /dashboard/ path)
• K8s API: https://10.0.20.100:6443
• Immich: port 2283 (use /api/server/ping)

Notes

1. Uptime Kuma uses Socket.IO (WebSocket) for its API, not REST
2. The uptime-kuma-api Python library wraps Socket.IO
3. Add time.sleep(0.3) between bulk operations to avoid overloading
4. Homepage dashboard widget slug: cluster-internal
