If that's what you want, then it looks OK to me. If you test it and it doesn't do what you expect, then you can start debugging it. > - which module can be used to implement Nagios check_ldap_startTLS? LDAP is a binary protocol. You won't be able to test this using blackbox_exporter, except for checking that a connection is accepted on port 389. You could look for a specific LDAP exporter. Or you could write a script which performs the check (e.g. by shelling out to "ldapsearch") and returns prometheus metrics. You can then run this script from cron and get it to write a file to be picked up by node_exporter's textfile collector; or you can run it under exporter_exporter; or you can write your own exporter <https://prometheus.io/docs/instrumenting/writing_exporters/> (basically just a small webserver which listens for scrapes). Alternatively, if you already have a Nagios check module which does what you want, you can run it under nrpe_exporter. > - Is there a way to know what does smtp_startTLS module exactly do? It negotiates a TLS connection on the TCP stream. If it's successful, all the subsequent communication on this stream is TLS-encrypted. I'm not sure what else to say about it! -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
