Perfekt, dankeschön!

Hornochs · 2021-06-15T12:26:04Z

Heyho :)
Danke dir erstmal für dein Skript! Bringt mich weiter :) Jedoch hab ich gemerkt, dass das System die selbe Notification zwei mal abschickt. Hast du eine Idee was es sein könnte?

LG

Hi,
der Skript darf nur mit einem Benutzer aufgerufen werden. Bitte benutze den automation user dafür. Das sollte dein Problem lösen. 😉

Hornochs · 2021-06-15T19:15:30Z

Hehe, wie bereits im CheckMK Forum geschrieben, hast vollkommen recht 😄 Hier war ein Noob mal wieder am Werk

Hornochs · 2021-09-22T19:13:42Z

Hey there,

Sure it does. You must setup on CheckMK when he should notify snd over which way :)

Hey Guys,

Edit, managed to get it working but getting the following error now:

Hi,

I answered your forum post to you problem.
Have a look and let me know if it helps you -> https://forum.checkmk.com/t/check-mk-discord-notification/29311/4?u=norm

Kind Regards
Norm

qhgh · 2023-05-09T14:09:32Z

Hi Norm,

Is there any way to have this script use the webhook with the 'role mention role id' so it can @ tag people?

I assume maybe somewhere here?

def post_request(message_constructor, success_code=204):
    context = collect_context()

    url = context.get("PARAMETERS")
    r = requests.post(url=url, json=message_constructor(context))

Thanks,
C

n00rm · 2023-05-12T12:57:39Z

Hi @qhgh

yes it should be pretty easy to add that function.
You can use the Enviroment Variables to get that info to the script.
https://docs.checkmk.com/latest/en/notifications.html#_environment_variables

You could use the Pager ID as a mention Role ID or create multiple notification rule with the mention id as a parameter and use the NOTIFY_PARAMETER_2 variable.

You have a full stop at the end of the code, please remove

qhgh · 2023-05-12T16:04:36Z

Doh!

Glowsome · 2023-08-30T00:20:21Z

Would it be possible to make a switch so notifications become more condensed ?
Meaning the discord message becomes more lean and displays as following:
Service Notification: (carriage return here) Service: service name (carriage return here) Host: Hostname (carriage return here) State: State_here (carriage return here) Detail: detail msg here (carriage return here)

Why : when you have a large amount of hosts it is preferable to see the messages in a more condensed way (saves scrolling).

Hope to hear back from you :)

Glowsome · 2023-08-31T00:15:43Z

Also one thing i did change in the script was the value of AVATARURL.
For some reason it never took hold, and got the default 'Wumpus' avatar witth the notifications.

After some digging i changed it to : "https://checkmk.com/android-chrome-192x192.png" - which works and shows the logo of CMK as avatar.
