Script check Docker Mem cpu

Bash file monitor --> docker_check_cpu_mem.sh (chmod +x)

✅ Audit Services Docker (CPU / RAM / Swap)

Objectif : limiter les pics RAM, éviter OOM, et garder des services réactifs. Format conseillé dans docker-compose (compose classique) :

  • cpus: "X.Y"
  • mem_limit: XXXm|Xg
  • memswap_limit: XXXm|Xg

✅ goaccess

  • Status : Up ✅
  • CPU : cpus: "0.5"
  • RAM : mem_limit: 768m
  • SWAP : memswap_limit: 1536m
  • Remarque : parsing logs => pics possibles.

⚠️ pulse

  • Status : Exited ❌
  • CPU : cpus: "0.5"
  • RAM : mem_limit: 1g (ou 2g si beaucoup de hosts)
  • SWAP : memswap_limit: 2g (ou 4g)
  • Remarque : sans /var/run/docker.sock => pas de monitoring Docker local.

⚠️ photoprism

  • Status : Exited ❌
  • CPU : cpus: "2.0"
  • RAM : mem_limit: 2g
  • SWAP : memswap_limit: 4g
  • Remarque : indexation/photo => très gourmand.

✅ big-bear-adguard-home-host

  • Status : Up ✅
  • CPU : cpus: "0.25"
  • RAM : mem_limit: 256m
  • SWAP : memswap_limit: 512m
  • Remarque : service léger.

✅ syncthing

  • Status : Up ✅ (healthy)
  • CPU : cpus: "1.0"
  • RAM : mem_limit: 512m
  • SWAP : memswap_limit: 1g
  • Remarque : pics possibles selon volume fichiers.

⚠️ n8n

  • Status : Created (pas lancé) ⚠️
  • CPU : cpus: "1.0"
  • RAM : mem_limit: 1g
  • SWAP : memswap_limit: 2g
