RavenDB Prometheus exporter

Exports RavenDB metrics and allows for Prometheus scraping. Versions prior to 4 are not supported due to different API and authentication mechanism.


From source

You need to have a Go 1.20+ environment configured.

go install
ravendb_exporter --ravendb-url=

Using Docker

docker run -d -p 9440:9440 -e RAVENDB_URL= marcinbudny/ravendb_exporter


The exporter can be configured with commandline arguments, environment variables and a configuration file. For the details on how to format the configuration file, visit namsral/flag repo.

Flag ENV variable Default Meaning
--ravendb-url RAVENDB_URL http://localhost:8080 RavenDB URL
--port PORT 9440 Port to expose scrape endpoint on
--timeout TIMEOUT 10s Timeout when calling RavenDB
--verbose VERBOSE false Enable verbose logging
--ca-cert CA_CERT (empty) Path to CA public cert file of RavenDB server
--use-auth USE_AUTH false If set, connection to RavenDB will be authenticated with a client certificate
--client-cert CLIENT_CERT (empty) Path to client public certificate used for authentication
--client-key CLIENT_KEY (empty) Path to client private key used for authentication
--client-key-password CLIENT_KEY_PASSWORD (empty) Password for the client key (if it is encrypted)

Sample configuration with authentication, for Docker:

docker run -d \
-e CA_CERT=/certs/lets-encrypt-x3-cross-signed.crt \
-e USE_AUTH=true \
-e CLIENT_CERT=/certs/admin.client.certificate.myserver.crt \
-e CLIENT_KEY=/certs/admin.client.certificate.myserver.key \
-v /path/to/certs/on/host:/certs \
-p 9440:9440 \
