zcashd can now be configured to optionally expose an HTTP server that acts as a Prometheus scrape endpoint. The server will respond to
GET requests on any request path.
To enable the endpoint, add
-prometheusport=<port> to your
zcashd configuration (either in
zcash.conf or on the command line). After restarting
zcashd you can then test the endpoint by querying it with e.g.
By default, access is restricted to localhost. This can be expanded with
-metricsallowip=<ip>, which can specify IPs or subnets. Note that HTTPS is not supported, and therefore connections to the endpoint are not encrypted or authenticated. Access to the endpoint should be assumed to compromise the privacy of node operations, by the provided metrics and/or by timing side channels. Non-localhost access is strongly discouraged if the node has a wallet holding live funds.
The specific metrics names may change in subsequent releases, in particular to improve interoperability with
