# LOKI PROMTAIL GRAFANA
|
||||
|
||||
Simple stack pour monitorer les logs des conteneurs ou applications d'un serveur via LOKI / PROMTAIL
|
||||
|
||||
## CONFIGURATION
|
||||
|
||||
Pour que LOKI récupère les logs des conteneurs il faut ajouter les labels au docker-compose.yml:
|
||||
```yml
|
||||
labels:
|
||||
logging: "promtail"
|
||||
logging_jobname: "containerlogs"
|
||||
```
|
||||
|
||||
## UTILISATION
|
||||
|
||||
```bash
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
## DASHBOARD
|
||||
|
||||
> Faire la dashboard standard
|
||||
