Hi,
I have a two master HA configuration that doesn't seem to be working as
expected.
These are running Icinga2 2.5.4.
One master(cmon-03) was configured as master with the wizard, the other
as client(cmon-04), both masters have icingaweb configured.
Each hasitsown postgresqldatabase and one syncs the configuration to the
otherusing zones.d(except for the cluster checks that I'm still working on).
The zones.conf looks like this in both servers:
object Endpoint "cmon-03" {
host = "cmon-03"
}
object Endpoint "cmon-04" {
host = "cmon-04"
}
object Zone "global-templates" {
global = true
}
object Zone "master" {
endpoints = [ "cmon-03", "cmon-04" ]
}
[ client zones configs and endpoints ]
Clients are defined in zones.d/master/hosts.conf and there is a
zones.d/global-templates with all the common information, none of those
include the two masters. All clients and the "second master(cmon-04)"
are configured to accept commands from the api.
I can see clients receiving the checks from both in their logs, and
icinga2web shows in both similar BUT not identical informationand that
is the source of my concern:
Some of the acknowledgederrors in one (cmon-03) don't seem to be
acknowledged in the other(cmon-04), on the one with no acknowledgements,
I can seethe MonitoringHealth complaining abouta "Backend icinga is not
running" .
Icinga2 IS running and an "icinga2 node list" returns just fine in both
systems, but somehowthe master receiving the configuration (cmon-04),
doesn't seem to be aware of itself, restarting icinga2 doesn't do
anything to the web interface, changes in the configuration aren't
reflected in it either despite the fact that /var/lib/icinga2/api/zones
data is consistent with the one in the other master (cmon-03)
I see no error in the logs indicating issues with the connection between
the two, I do see:

There is no log in cmon-03, but there is on cmon-04:

Even removing those and restarting, doesn't change the web view, checks
seem to be running fine, but if/when the main master fails, I want to be
able to rely in the other one at the same level.
I'm sorry if this are too much of a newbie question and thanks in
advance any help you can provide.
Best,
