monitor_ssl_identity

The digital certificate used for the Server Health and Metrics HTTPS listen in PEM, DER, or PKCS#12 format. You can specify the path to a file that contains the certificate in one of the supported formats.

monitor_ssl_identity = certificate

If this parameter is not specified, the identity file configured for the server’s TLS listen is used in its place. If neither are specified, the server will fail to start up.

PEM, PKCS#12 formats allow the digital certificate to include the private key. If these formats are used and the private key is part of the digital certificate, then setting
monitor_ssl_key is optional.

For example:

monitor_ssl_identity = certs/server.cert.pem
