[Check_mk (english)] QNAP Disk status

Hello !
QNAP 4.1.3 doesn't reply a correct information to Check_mk plugins

In my case one drive was dead and I see two different output:
a) in the QNAP's administration web pages the Drive was dead
b) in the WATO I see the Model and size but not the Temperature and the status was ok

So I have update the QNAP to the last version 4.1.4 but may be possible to flag the critical status if one of the
disk's parameters are missing?

Hi List,


We are currently moving from mysql to MariaDB and were wondering if there is a check available to monitor MariaDB multimaster replication. In our current setup we have 1 slave db server replicating mulitple master servers and want to monitor slave lag en io status.



cheers

[Check_mk (english)] Remove duplicated status from dashboard

A common notification on dashboard:

StateHostServiceIconsStatus detailAgeChecked
CRIT WindowsHost fs_F:/
CRIT - 96.7% used (FREE: 23.80 of 720.00 GB), (levels at 75.00/90.00%), trend: +528.79 MB / 24 hours 2015-07-10 14:52:31 53 sec

As you can see, the "State" column already show the "CRIT". I don't want it to be repeated on "Status detail".

I want something like this:

StateHostServiceIconsStatus detailAgeChecked
CRIT WindowsHost fs_F:/
96.7% used (FREE: 23.80 of 720.00 GB), (levels at 75.00/90.00%), trend: +528.79 MB / 24 hours 2015-07-10 14:52:31 53 sec

Thank you very much!!!!

[Check_mk (english)] Windows Updatae Plugin - 100% CPU

Has anyone experience high CPU (pegged at 100% indefinitely on single-vCPU VMs) as a result of using the windows_updates.vbs plugin distributed with OMD?


Here are my ini settings:


    execution windows_updates.vbs = async
    timeout windows_updates.vbs = 900
    cache_age windows_updates.vbs = 14400
    retry_count windows_updates.vbs = 3


We noticed some VMs 100% CPU and tracked it back to windows update (was a svchost.exe process consuming the CPU).  Restarting Windows Update service helped for a little while then it came back.  So then I thought maybe it was the plugin so I removed it from the plugins directory, restarted Windows Update, and the high CPU usage has not come back since.


It seems it affected other multi-vCPU and physical servers, but it wasn't as obvious as it was on single-vCPU VMs.


FWIW, the script usually does work.. but this time it seems to have gotten hung up on something.  Checking for updates using the point and click method works fine on these servers.

Thank you,
Lance

[Check_mk (english)] OMD/WATO: dual check, check_mk_agent and vsphere agent

I am trying to get a dual check with the base check_mk_agent (via ssh) 
and vsphere agent at the same time on a host.

I can run each individually working but when I tag it with both 
ssh/vsphere agent it will only "discover" vsphere and the 
ssh/check_mk_agent tests are now missing.

Is it possible to have both at the same time? Well, I know it's possible 
because I've configured it on my "manual" configured system but im 
wondering if it's possible to configure OMD/WATO to do this?

I've had similar problem with a dual snmp/check_mk_agent configuration 
as well.

[Check_mk (english)] check_mk cached local checks - scripts must return '0'?

        https://mathias-kettner.de/checkmk_localchecks.html

        It looks like the scripts in $LOCALDIR/[0-9]+/* must return 0, or
the cache files are automatically deleted and no reporting is provided.
This restriction doesn't apply to checks in simply $LOCALDIR.  From the
'run_cached()' script:

    echo "set -o noclobber ; exec > \"$CACHEFILE.new\" || exit 1 ; $CMDLINE && mv \"$CACHEFILE.new\"
\"$CACHEFILE\" || rm -f \"$CACHEFILE\" \"$CACHEFILE.new\"" | nohup bash 2>/dev/null &

        Is this intentional?  If so, it should probable be documented as
such.  

        (Tested on check-mk-agent-1.2.4p5-2.el6.x86_64 on RHEL6).

[Check_mk (english)] OMD with Icinga and icinga-idoutils

Hi there,

Is there a way to use OMD with Icinga and icinga-idoutils? We need 
idoutils for icingaweb2.

Currently we are running the manual installation with check_mk + icinga 
+ icingaweb2 but we would like to use OMD if possible.

Thanks in advance,

Nikola

[Check_mk (english)] Change used for free (disk space)

Common check_mk (dashboard) output for a disk:

CRIT - 96.6% used (695.71 of 720.00 GB), (levels at 75.00/90.00%), trend: +428.67 MB / 24 hours

Is there an easy way to change the "% used"? Instead, i want it to show "% free".

Thanks!!
