I've got an IPA installation with 8 servers replicating between each
other across various parts of our network. Recently I've started
pushing the dirsrv logs to a remote log collector from 4 of these
machines and see a huge disparity in the number of entries being sent.
ipa01 - ~42,000 logs per hour
ipa02 - ~13,000 logs per hour
ipa03 - ~80,000 logs per hour
ipa04 - ~20,000 logs per hour
ipa01 & 02 are used as a failover pair for clients in one datacentre.
ipa03 & 04 are used as a failover pair for clients in another
>From the logs, is there a way to see if I've got an imbalance of clients
connecting to each IPA server? Or a completely different log message
We don't have access to the _SRV_ records as the AD domain controls
that, so we had to hard code the main and failover servers on the
ipa_server line in /etc/sssd/sssd.conf, the kdc line in /etc/krb5.conf,
and the URI line in /etc/openldap/ldap.conf. As such, it's reasonable
to suggest that our randomised script for allocating primary/secondary
on a client isn't as random as we think.
Might it also be possible that due to the hard coding option we had to
take, our clients end up failing over to a certain server, but then
never failing back when the primary returns? Under maintenance we
generally patch and reboot the odd numbered servers, followed by the
even servers once the odd servers are back.
