Storage Options

Built-in MongoDB (default)​

global:
  installMongo: true

mongodb:
  persistence:
    enabled: true
    size: "10Gi"            # adjust for production
    storageClass: "fast-ssd"

External MongoDB​

global:
  installMongo: false
  mongodb:
    hosts: "mongo1.example.com:27017,mongo2.example.com:27017"
    username: "elchi"
    password: "secure-password"
    database: "elchi"
    replicaset: "rs0"
    tlsEnabled: true

Built-in VictoriaMetrics​

global:
  installVictoriaMetrics: true

victoriametrics:
  storage:
    size: "20Gi"
    storageClass: "standard"
  retentionPeriod: "30d"

External VictoriaMetrics​

global:
  installVictoriaMetrics: false
  victoriametrics:
    endpoint: "http://victoria-metrics.monitoring:8428"

Built-in ClickHouse (default)​

ClickHouse holds the raw API-events stream that feeds API discovery. It is bundled by default and consumed by the elchi-collector:

global:
  installClickhouse: true
  installCollector: true

External ClickHouse​

Point the collector at an existing ClickHouse cluster instead of the bundled one:

global:
  installClickhouse: false
  clickhouse:
    hosts: "clickhouse.example.com:9000"
    password: ""   # set your own — do not commit it
Sizing guide
  • MongoDB — 10 GB for small deployments, 50 GB+ for production.
  • VictoriaMetrics — 20 GB for ~30 days retention; scale with metric volume.
  • ClickHouse — sized by event volume and retention (default 7-day TTL on raw events).
  • SSD-backed storage classes give meaningful headroom for all three.
