What is the command and user "check-mk-notify"

[GianlucaUlivi]

Hi All,

I have configured a few months ago my CheckMK to send me Telegram notifications for host and services and it is working great.
I have noticed that if I go to “Notification of Host and & Services for XXXX” I do see two lines for each notification I received, one is my contact (AlertBot) with my notification script/command (check_mk_telegram-notify.sh) and the other have “check-mk-notify” in both the contact and command field.

Same in the “Event of Host & Services for XXX”
(Cannot upload a second screenshot because I’m a new user)

I was not able to find any information on this contact or command, is it something used internally by CheckMK?
Is it needed if I do already have a custom notification method?
If is not needed, how can it be removed/disabled?
I would prefer to see only a single line for notification as that would make it much more clear to read.

CheckMK Version is 2.0.0p3
OS Version is Centos 8

PS: I Know that from the notification page if I click on my contact I only see the notification sent to it and not the “check-mk-notify” ones, I would prefer to always remove/disable the other notification line as it does not give me any extra information.

Many thanks to everyone,
Best Regards,
Gianluca

The first entry with “check-mk-notify” is the notification generated by the monitoring core.
The second line is the result of the rule based notification evaluation.
In your case the result is then the telegram script for the user “AlertBot”.

If you only see the first line then your notification system had no matching rule for this notification.

Hi and thanks for your reply.
So the entry with “check-mk-notify” is, as I suspected, an internal process and will always be present?
The Telegram notification with user “AlertBot” is working fine so no problem on that, I just wanted to understand better what was the first entry.

Thanks.

Yes it’s like you suspected.
