Hi, sorry for the delayed response on this.
My check looks like this:
object Service "mydb" {
import "generic-service"
host_name = "somehost.mycompany.com"
check_command = "postgres"
vars.postgres_host = "somehost.mycompany.com"
vars.postgres_dbname = "catalog"
vars.postgres_dbuser = "mon"
vars.postgres_dbpass = "mon"
vars.postgres_action = "connection"
}
This check generates the error "Peer authentication failed for user "mon"",
which after some digging is the result of the lack of a -H (host) parameter
to check_postgres.pl. Note that in
/usr/share/icinga2/include/plugins-contrib.d/databases.conf
the CheckCommand object includes "vars.postgres_unixsocket = false", and
the -H argument has "set_if = {{ macro("$postgres_unixsocket$") == false }}".
Since I haven't defined postgres_unixsocket to be true (or anything else)
the expectation is for the -H to be passed, but this doesn't happen.
I can't say whether my proposal to surround the "false" in quotes is the
right fix as I'm far from an icinga2 language expert... But there's
definitely some type mismatch going on: the result of the macro() function
seems to be a string regardless of its parameter.
Thanks for the link to the developer guidelines. I still can't find an
issue tracker though (which is where this conversation could take place),
maybe consider activating issues in github?
Thanks for all your help and for making an awesome monitoring system!
Shay
