status of CMP endpoint

[kuehne-trustable-de]

I would like to check whether a CMP endpoint is available. My trivial approach is to send a 'PKI Information Request'. But the ejbca log tells me

2023-01-04 14:41:21,462 INFO [org.ejbca.core.protocol.cmp.CmpMessageDispatcherSessionBean] (default task-30) Received an unknown message type, tagno=21
2023-01-04 14:41:21,462 ERROR [org.ejbca.core.protocol.cmp.CmpMessageDispatcherSessionBean] (default task-30) Can not handle message type '21'.

What's the recommended way to query the CMP status ?

If you just want to check availability, you can always to a CertConf, it will always return a PKIConf.

I think once we suggested, using CMP Client mode, doing CertRep, with a random invalid end entity. It will return a consistent error, and then you also have somewhat of a check that EJBCA is running as expected, at least the database is functioning etc.
