Arango Monitoring
Configuration
Arango requires a scrape configuration be added to the prometheus.yml. (https://www.arangodb.com/2020/03/monitoring-arangodb-prometheus-grafana/)
- job_name: arangodb
scrape_interval: 5s
metrics_path: /_admin/metrics/v2
bearer_token: eyJhbGciOiJIUzI1NiIsInR5cIkpXVCJ9.eyJwcmVmZXJyZWRfdXNlcm5hbWUiOiJyb290IiwiaXNzIjoiYXJhbmdvZGIiLCJpYXQiOjE2OTE2NjA4NTUsImV4cCI6MTY5MTY2NDQ1NX0.KzZlSXseLrBrRci9cZn_D9f97fSNHQABSTLbTSMi5VA
static_configs:
- targets: ['arango.development.svc:8529']
Arango automatically exports metrics to port 8529. However Arango does require a bearer_token to authenticate.
Dashboard
Some additional dashbaord can be found here : https://github.com/arangodb/dashboards
We use the following dashboard for arango monitoring:
