Nagios Support Forum

Hey all,

Not sure if this was answered in another post. I'm trying to get an executive summary of all the disk spaced used on all our machine monitored by NAGIOS. Is there a plugin or a way to get an Executive Summary of Disk usage throughout all machines monitored by NAGIOS? I'm currently running Nagios XI 2014R2.7

Any help with getting this will be greatly appreciated!!! or pointing me to the right direction.

Depends - we have our metrics component which can do a pretty good job of aggregating disk usage for certain service types, but not all. For example (today) we cannot add in disk space gathered using an SNMP check. It's basically just the stuff gathered using NRPE (Linux Server wizard) and NSCP (Windows Server wizard). If you used those wizards for everything, you should be able to get what you want.

If this doesn't suit your needs, the best answer I have to offer is that we're looking to expand the usefulness of that component in the future, but I know of no better way to achieve your goal today.

thanks for the update. I'm currently trying to run a script that will do this for us but haven't been successful yet.

If all the checks have the same service_description, you can get them from the Backend API URL component

Admin -> Manage Components ->Backend API URL Component -> Edit

Select User

Copy URL for "Current Service Status"

Then, append "&service_description=<YOUR_SERVICE_DESCRIPTION>"

This will filter the XML down to just services that match your description

I tried that w/ wget and all I got back was authentication error in the saved file. Works fine manually though. I added &password=<correct password> but still no luck. Any hints?

Recent data is also in the DB and is easy to get to via script. I just made a cheesy subroutine in perl to run the sql but would look into DBI once I get the concept worked out.

# mysql
mysql> use nagios
mysql> select name1 Hostname, name2 'Service Name', current_state Status, status_update_time 'Check Time', perfdata 'Performance Data' from nagios_objects, nagios_servicestatus where object_id = service_object_id and is_active = 1 and name2 like 'FS_Win_Usage' order by name1, name2;

Can you show us the command that you tried? Hide sensitive info.

In a browser this works as you said:
https://host/nagiosxi/backend/?cmd=gets ... _Unix_Load

But using a browser defeats the purpose of automating things.
I tried with and without --no-check..., as http/https, and tried curl with the same result.

When you do the wget command you need to put the entire URL in quotes " "

You're right. That made it work.
Thanks!

Is this one all right to mark resolved?
