zabbix rabbitmq reports not running after clean deployment

[Sam Stoelinga]

Description: A clean non-ha environment deployment in virtualbox reports that rabbitmq is not running. Fix is described below.

Steps to reproduce:
1. Create a new non-HA environment using Ubuntu with experimental features enabled
2. Deploy 4 node cluster: 1 controller, 1 compute, 1 cinder-lvm, 1 zabbix node

Fuel version: 6.0 official release

Current result:
Zabbix shows RabbitMQ Server process is not running on node-1.domain.tld

Expected result:
After a clean deployment zabbix shouldn't show any errors.

Quick Fix:
Go to the Template App OpenStack RabbitMQ and change the item "RabbitMQ EPMD process is running" from proc.num[,rabbitmq,,bin/epmd] to proc.num[,,,bin/epmd]

The fix removes the check for which user is running epmd, my guess is that if HA is enabled the rabbitmq service started by pacemaker is running under the rabbitmq user, while when non-ha is enabled the rabbitmq service started via init.d is started by root user. If so I suggest the code fix to make sure that HA and non-ha use the same user to start rabbitmq?

Would like to do the code fix myself as exercise

    Rabbitmq reported not running in zabbix

    RabbitMQ is reported as not running when rabbitmq is run
    as root user. This patch removes the check as which
    user rabbitmq is running.

    This may introduce a security issue if our purpose was to
    make sure that rabbitmq is always run as rabbitmq user.
    If so please discard this patch and change init script
    of non-ha mode to run RabbitMQ as rabbitmq user.

any reason why it did not get included in 6.1, seems there is a regression? I just reproduced this on 6.1

[Sam Stoelinga (sammiestoel)]

seems the fuel-plugin-external-zabbix did not use the latest code, so there may be several regressions introduced that were fixed in latest Fuel code. I've submitted a patch to the fuel-plugin-external-zabbix

    The fuel-plugin-external-zabbix did not backport latest
    code of Fuel, causing a regression. The following
    patch was not ported to fuel plugin:
