Good morning everyone.
After upgrading i had several problems. Windows-Agents crashes, check_mk: ERROR: Duplicate service description on many servers and so on…
It is a nice release and a step forward but i never had that many erros with a release. Used 1.6.21 before the update.

9

That would be strange as the normal Windows agent is queried the same way as before.
Can you please create an own thread for the problem as it looks like a litte bit more than one simple answer.

Where can I find “Classical active and passive Monitoring checks” in 2.0.0 , please ?

11

You need to search for “Integrate Nagios plugins” or only Nagios

12

:+1: @andreas-doehler thanks a lot!

It’s here now:

Setup > Services > Other services > Integrate Nagios plugins

13

Now I am searching for “Fake check results” after doing a Service Search, can’t find it anymore.

In 1.6.0 this was reachable like this:

 Service Search
     Hammer Icon
        Fake check results
14

Take a look at the roles. Fake check result is deactivated in all roles with default settings.

15

:+1: @andreas-doehler you are right, I thank you again !

16

Do these changes also apply to the Raw version?

What are the changes between version 1.6 and 2.0 Raw?

17

Hi Gustavo,

Most of the changes apply to the Raw edition as well. For an overview of what’s new, you can check this page. There’s a note there whenever a feature is only for the Enterprise edition.

I am looking for the equivalent of WATO > Event Console > Rule packs. In Checkmk 2.0 I can only find Settings > Events > Notifications.

20

You have to click “show more” in the top right of the menu in order to see Event Console.
