Automation of disabling earmand

[T.J. Yang]

I have a mod_gearman on a Nagios 3.5.1 server(CentOS 6.6) with job/worker on same box, 

I found I need to run following commands in sequence to completely disable mod_gearman.

So that I can observe performance with/without mod_gearman.

1. /etc/init.d/mod_gearman_worker stop

2. /etc/init.d/gearmand stop

3. vi /etc/nagios/nagios.cfg # to comment out mod_gearman.o broker

4. /etc/init.d/nagios reload

Is above sequence correct ? 

Can I leave mod_german_worker running ? 

If I skip 3. and 4., will nagios daemon crash or suffer ?

I am tempting to automate 2,3,4 steps into a command like "/etc/init.d/geamand disable"

Comment out the mod_gearman.o broker and restart Nagios. Nagios will
then handle all host and service checks by itself.

After Nagios has restarted, the "mod_gearman_worker" and "gearmand"
services will consume a tiny bit of resources while running, but can be
stopped at this point.

When I left mod_gearman.o loaded and only disabled job server and worker daemon, I found all service/host checks stopped.

Is this expected behavior  ?

    I think all the checks still get sent to the gearmand queue where the worker was supposed to process them and delivery back the results to the check_results queue.
    You have to comment out the broker on nagios / naemon,

if this the case, shouldn't following actions/logics be performed ?

1.  /etc/init.d/gearmand start: check if mod_gearm.o is in /etc/nagios/nagios.cfg or not

     1.1 Yes ? startup gearmand (job server).

      1.2 No ? add/enable mod_gearman.o line in nagios.cfg

           1.2.1 reload nagios

2.  /etc/init.d/gearmand stop: 

    2.1 kill gearmand deamon

    2.2 remove/comment out mod_gearman.o line in nagios.cfg

    2.3 reload nagios

    I'd just comment out the broker on nagios and restart it, as gearmand and mod_gearman_worker wont consume that much resources when doing nothing on the server and simplifying the enabling / disabling process.
