CheckMK Notifications as Tickets - Using SystemMonitoring Plugin?

[irony]

Hello together

i would love to connect the Notifications of my CheckMK with Znuny.

- Notifications of Type <anything> should be seen as incidents.
- Notifications of Type OK should be seen as "close the ticket state to successfully closed".
- Each Notification has a unique ServiceID and/or HostID.
- Notifications of the same ServiceID should not resolve in the creation of a new ticket, rather an update of the old one.

basically, just how you would expect it to work.

I have heard there is the SystemMonitoring Plugin, but i am not too familiar with how Postmaster Filter and so on work. Can anyone explain me how to set it up? Basically i expect it to be a Filter, but i don't understand how much of filtering i need to adjust at what position.

I have implemented this via API Call, but it requires User Data in cleartext placed in the script of the monitoring CheckMK instance, which we don't want.
Mails don't require authentification, therefore it's a better solution here.

Thanks for your help in advance!

Hi,

If you have implemented it via API call there is on solution to remove the UserData from CheckMK: you can add them into the mapping. The only important thing then is that you have to ensure that only CheckMK is using the web service. You can enforce this with Apache configuration by using additional authentication or client IP limitation.

The SystemMonitoring add-on is technically a PostMaster filter that extracts the require parts out of CheckMK's emails.
This are the relevant regular expressions that are used:

1. StateRegExp -the value of current state in the mail
2. HostRegExp - the related host
3. ServiceRegExp - the service
4. NewTicketRegExp - possible match when a new ticket should be created. (Service is CRITICAL, Host id DOWN)
5. CloseTicketRegExp - possible match when the ticket should be close (Service is OK, Host is UP)
6. CloseActionState - the state to be set when a ticket is closed

The setting FromAddressRegExp is to make sure only wanted sender are processed.
