[Check_mk (english)] Info on the website of check_mk

I am missing the option "--update-dns-cache" what is more
of a major command to me.

Maybe if there is time you all can list it there.

[Check_mk (english)] How can users modify their contct groups?

Hi list,
As admin I can easily put users into contact groups, but I do not find
this option if logged in as normal user. Are there any permissions to
be set or is it simply not possible to modify contact group membership
as limited user?
Thanks and regards

I have copied the wmic_if.bat file into the Windows host running check_mk agent, and re-inventorised the host.

However, I am unable to see the new service attached to the host.

Any idea?

[Check_mk (english)] Email notifications

Hi /all

my Check_MK doesn't send email notification today

I have send notification from nagios, with Send custom service notification
it's ok, users receive it. Notify.log returns me

Got notification context with 37 variables
Notification context:

but when I do a cmk --notify , the notify.log returns me
Got notification context with 0 variables

I've test yesterday and it worked well, (automatic email when alert on a host, cmk --notify, it was ok)
I remember I have just disable notification for my test user
in order to stop spamming him until I'm ok with notification's trigger.

is anybody have an idea please?

[Check_mk (english)] Windows servers: user/wait/system CPU utilization


Currently, with the Windows servers which I monitor with OMD, I get 
graphs with a single value for CPU utilization. I would like to get 
graphs where I can tell the distribution of user-space time, wait-time 
and system time -- like I get for monitored Linux servers.

Is that possible?

check_mk version: 1.2.4p5.

Re: [Check_mk (english)] Set the \"from\" address in Check_MK?


Nice.  I'll look into upgrading.  Thanks Patrick.

I'm not sure rule based notifications will allow for setting the from address in WATO, but haven't looked at it other than the documentation page.

I am eager to move to RBN, but am waiting until it is in a stable branch.

I've got a mix of omd 1.11 and nagios xi w/ check_mk installed along side.

The mailer way works, but it's not flexible. You want the newer versions of check_mk with Rule Based notifications. Depending on the notification method, you can set the from address.

Thanks Laura and Andreas,

I did end up doing it at the system mailer (postfix) using sender_canonical and regexp.  I was hoping there was a way to set it in the check_mk configuration but doing it at the postfix level works.

<at> Laura - I actually needed to change sender from "nagios-WI0L6dQK/Vp31WWMw7KoMmZHpeb/A1Y/@public.gmane.orgocal" to "sitecodenagios-9IKiO1iGCm/".

If you send your email with the system mailer then you can change the "from" with your system settings (postfix / sendmail).

[Check_mk (english)] Edit Jolokia Check Thresholds via WATO

Hi All,

Just a quick question about the extra checks that are picked up for JVM monitoring via Jolokia & the mk_jolokia plugin.

At the moment I can only edit the jolokia_metrics.mem metric through the WATO GUI. Any of the other checks that have thresholds (like threads) cannot have their metrics changed (theres no icon next to them to change the thresholds in the services view).

Am I missing something, or is this not in place yet? Is it available in a newer version?

Running OMD 1.00 with Check_MK 1.2.2p2

Many Thanks
