#HomeAssistant #OpenSource #Monitoring #Observability

A few days ago, a client’s data center (well, actually a server room) "vanished" overnight. My monitoring showed that all devices were unreachable. Not even the ISP routers responded, so I assumed a sudden connectivity drop. The strange part? Not even via 4G.

I then suspected a power failure, but the UPS should have sent an alert.

The office was closed for the holidays, but I contacted the IT manager anyway. He was home sick with a serious family issue, but he got moving.

To make a long story short: the company deals in gold and precious metals. They have an underground bunker with two-meter thick walls. They were targeted by a professional gang. They used a tactic seen in similar hits: they identify the main power line, tamper with it at night, and send a massive voltage spike through it.

The goal is to fry all alarm and surveillance systems. Even if battery-backed, they rarely survive a surge like that. Thieves count on the fact that during holidays, owners are away and fried systems can't send alerts. Monitoring companies often have reduced staff and might not notice the "silence" immediately.

That is exactly what happened here. But there is a "but": they didn't account for my Uptime Kuma instance monitoring their MikroTik router, installed just weeks ago. Since it is an external check, it flagged the lack of response from all IPs without needing an internal alert to be triggered from the inside.

The team rushed to the site and found the mess. Luckily, they found an emergency electrical crew to bypass the damage and restore the cameras and alarms. They swapped the fried server UPS with a spare and everything came back up.

The police warned that the chances of the crew returning the next night to "finish" the job were high, though seeing the systems back online would likely make them move on. They also warned that thieves sometimes break in just to destroy servers to wipe any video evidence.

Nothing happened in the end. But in the meantime, I had to sync all their data off-site (thankfully they have dual 1Gbps FTTH), set up an emergency cluster, and ensure everything was redundant.

Never rely only on internal monitoring. Never.

Hier wie #Hermes meine Linux-Systeme (Linuxe und Linuxinas) automatisch aktuell hält

Nächtliches Server-Checkup als Best Practice Blueprint

Zwei-Phasen-Architektur mit strikt getrennten Verantwortlichkeiten:

PHASE 1 — DATENSAMMLUNG (System-Cron, 01:00)
Bash-Script, kein LLM. Führt alle Checks sequentiell aus und schreibt das Ergebnis in ein versioniertes Logfile (check_YYMMDD.log). Log-Rotation automatisch (30 Tage). Jedes Modul darf einzeln fehlschlagen ohne den gesamten Check abzubrechen.

PHASE 2 — BENACHRICHTIGUNG (Hermes-Cron, 02:00)
Python-Parser, kein LLM. Liest das Logfile deterministisch ein, baut einen kompakten Report, generiert automatische Alerts bei Schwellwert-Überschreitungen. Das Script-stdout wird 1:1 als Telegram-Nachricht zugestellt. Hermes startet keinen Agent-Loop — reiner Cron-to-Telegram-Bridge.

DESIGN-PRINZIPIEN

1. Decoupling: Checks laufen über System-Cron, nicht über den Bot. Fällt der Bot aus, liegen die Logs trotzdem bereit. Bot ist nur der Zusteller.

2. Deterministisch: Der Report wird von einem Python-Script geparst, nicht von einem LLM generiert. Keine API-Kosten, keine Halluzinationen, garantiert gleiches Format jeden Tag.

3. Asynchroner Versatz: Phase 2 startet 1h nach Phase 1 — das Logfile ist sicher vollständig, keine Locking-Mechanismen nötig.

4. Logfile als Schnittstelle: Der einzige Kontaktpunkt zwischen den Phasen. Versioniert, rotiert, manuell inspectable, kann jederzeit nachträglich geparst werden.

CHECK-DOMÄNEN
- Storage: SMART, Temperaturen, Verschleiß, Mount-Health
- Hardware: CPU/Sensor-Temperaturen, NVMe-Wear
- Pool: Kapazität, Auslastung, Merge-Status
- Identität: AD/Domänen-Anbindung, Trust, User-Sichtbarkeit
- Backup: Client installiert, Server erreichbar, letztes Backup
- Updates: Ausstehende Pakete, Reboot-Required
- Self-Update: Eigener Agent auf aktuellem Stand
- Prävention: Proaktiver Remount von Fuse-Pools (nicht nur bei Ausfall)

ALERTING
Zwei Lagen: 🔴 Alerts bei echten Problemen (SMART FAILED, AD offline, Reboot nötig). ℹ️ Hinweise bei Auffälligkeiten ohne akuten Handlungsbedarf. Keine Alerts = "Alle Systeme unauffällig."

WATCHDOG-PATTERN
Zusätzlich zum nächtlichen Check läuft ein Watchdog-Cronjob (alle 30 Min) für kritische Komponenten. Silent bei Gesundheit (0 Byte stdout = keine Nachricht, keine Notification-Fatigue). Bei Ausfall: Selbstheilung (z.B. Remount) + Telegram-Alert.

WARUM DAS FUNKTIONIERT
- Ausfallsicher: Jede Komponente kann einzeln ausfallen, alles degradiert graceful
- Kostenlos: Kein einziger LLM-Call in der Pipeline
- Reproduzierbar: Logfile + Parser = deterministischer Report
- Präventiv: Fuse-Pools werden proaktiv remounted, nicht erst bei User-Beschwerden
- Auditierbar: 30 Tage Logfile-Historie liegen lokal

Ohne es zu wollen hat mir die KI eine Suchanfrage geschrieben...

"Ich bin auf der Suche nach einer Vollzeitstelle als Systems Engineer in Augsburg, idealerweise auf der Ebene mit Berufserfahrung bis hin zu einer Managementposition. Ich bringe Kenntnisse in Systemintegration, DevOps und Automatisierung mit. Mein Wunschgehalt liegt bei 80.000 €."

Ich lach mich schlapp.

Management? Auf Keinen Fall.
80k? No way das zu bekommen...

• la communication sur les incidents (avec historique)
• avoir un uptime sur les services (idéalement d'un an... on a les SLA qu'on peu).

• openstatus (trop compliqué a installé hors docker) j'ai l'impression que ca fait le café mais avec des choix technologiques particulier.
• statusnook (installtion super simple en mode curl|bash que je n'ai pas fait, on regarde toujours avant d'exécuter)

Behind every high-impact Internal Developer Platform (IDP) lies a socio-technical system, but many platform teams struggle not with #YAML or #APIs but with attracting and retaining the right talent. A vast pool of skilled engineers hesitate to apply because they don't feel they belong, leaving organizations unknowingly missing out on innovation.

🎧 When your #observability stack struggles to handle growth, it’s time to reconsider. Spotify had to replace its outdated in-house #TimeSeries database due to stability problems and performance issues that led to slow queries and timeouts. To achieve high-throughput data ingestion, quick query responses, and dependable alerting at scale, Spotify’s Observability team selected VictoriaMetrics, recognized as the fastest #monitoring and observability tool available.

This may require substantial CPU, RAM, disk I/O, and disk space to store and query large log volumes. In this talk, we will look into different strategies of storing those #logs in #ElasticSearch, #Grafana, #Loki, and VictoriaLogs and examine how we can save 10x or more on infrastructure costs.

I had one problem (graphing different things from HTTP server logs), made a database that I can read from #Grafana, but now I have two problems (learns more #SQL so I can make my graphs).

For instance, this is my useless attempt to graph status code by time:

```
SELECT timestamp AS time, COUNT(status) as value
FROM logs
WHERE timestamp >= $__from / 1000 and timestamp < $__to / 1000
GROUP BY status
```

Anyone knows a good tutorial about it?
