4 years ago Hi!
Thank you for your quick response.
Hi @PlqnK currently it is not possible to set as a value of a macro another macro.
That's what your own documentation is asking though here https://docs.centreon.com/docs/centreon-engine/en/latest/user/configuration/advanced/monitoring_service_and_host_clusters.html#monitoring-service-clusters. It says that one need to create the following command:
define command{
command_name check_service_cluster
command_line /usr/lib/nagios/plugins/check_cluster --service -l $ARG1$ -w $ARG2$ -c $ARG3$ -d $ARG4$
}And then a service like that:
define service{
...
check_command check_service_cluster!"DNS Cluster"!1!2!$SERVICESTATEID:host1:DNS Service$,$SERVICESTATEID:host2:DNS Service$,$SERVICESTATEID:host3:DNS Service$
...
}Where the $ARG4 macro of the command is mapped to $SERVICESTATEID:host1:DNS Service$,$SERVICESTATEID:host2:DNS Service$,$SERVICESTATEID:host3:DNS Service$ in the service definition.
And even then, I tried to create a custom command with the on-demand macro directly inside it like so (/etc/centreon-engine/commands.cfg):
define command {
command_name check_dummy_custom
command_line $USER1$/check_centreon_dummy -s $SERVICESTATEID:Centeon-central:Cpu$ -o $SERVICESTATEID:Centeon-central:Ping$
}And udpate the "Dummy" service to directly use that custom command (/etc/centreon-engine/services.cfg):
define service {
host_name Centeon-central
service_description Dummy
check_command check_dummy_custom
check_period 24x7
max_check_attempts 5
check_interval 3
retry_interval 1
register 1
_SERVICE_ID 533
}But I get pretty much the same error message (/var/log/centreon-engine/centengine.debug):

4 years ago Hi @PlqnK, Actually, we did witness a similar behavior about on-demand macros. It seems that we have to backport a fix on the 19.10.x serie of Engine project. In the meantime, you should not use them as it can cause segfaults on Engine.

4 years ago Hi!
Alright, thanks for this information.
Do you know any other way of monitoring a cluster of service? I've tried to find some but was out of luck unfortunately.
I'm stuck with version 19.10 for the time being so any workaround would be greatly appreciated!

4 years ago Hi @PlqnK, Yes I do :) You can either use Centreon BAM (commercial product) with the ratio calculation method that fits cluster monitoring needs (https://docs.centreon.com/current/en/service-mapping/ba-management.html#calculation-methods), or use the virtual-service centreon-plugins mode (https://github.com/centreon/centreon-plugins/blob/master/apps/centreon/sql/mode/virtualservice.pm) but it requires some explanations (maybe @Sims24 can provide some as I think a Plugin Packs now exists for it).

BUG REPORT INFORMATION
Prerequisites
Versions
Operating System
CentOS Linux release 7.8.2003 (Core)
Browser used
Version: 78.0.2
Additional environment details (AWS, VirtualBox, physical, etc.):
I'm using the 19.10 OVA, imported into VirtualBox 6.1.10 r138449 running on Windows 10 1809 17763.1282. I've updated Centreon to the latest available version using the instructions from the documentation.
Description
I'm trying to configure and use the
check_clusterplugin according to the documentation here. In order to use it you must create a service which references an on-demand service macro.The problem I'm facing is that Centreon matches the on-demand macro but fails to process it.
To demonstrate it I've created a Dummy service using the
check_centreon_dummycommand attached to a host where$ARG1$is set to$SERVICESTATEID:Centeon-central:Cpu$(the typo on "Centeon" is expected, that's the default hostname in the 19.10 OVA) and$ARG2$is set to$SERVICESTATEID:Centeon-central:Ping$. Here's the resulting entry in/etc/centreon-engine/services.cfg:The services
CpuandPingexists and works fine on the hostCenteon-central:Steps to Reproduce
Centeon-centralhostcheck_centreon_dummycheck command$SERVICESTATEID:Centeon-central:Cpu$as$ARG1$$SERVICESTATEID:Centeon-central:Ping$as$ARG2$-sand-oarguments be empty.Describe the received result
When Centreon checks the service and processes the macro it doesn't work and the resulting command line arguments of the
check_centreon_dummyplugin are empty:Please see the centreon-engine debug log extract further down in the Logs section to see the exact error reported.
Describe the expected result
Centreon should process the macro and replace
$SERVICESTATEID:Centeon-central:Cpu$with the state ID of theCpuservice of the hostCenteon-central, in my case0as well as$SERVICESTATEID:Centeon-central:Ping$with the state ID of thePingservice of the hostCenteon-central, in my case0again.Logs
PHP error logs
centreon-engine debug logs
Additional relevant information (e.g. frequency, ...)
I've tried restarting the
cbd,centengineandcentcoreservices but it didn't solve the problem. Restarting the VM also didn't solve the problem.In the documentation it's said that toggling
use_large_installation_tweaksto1disables the on-demand macro processing, but it's default is0and even when forcing it to0the problem persists.
