Hello, I am using Checkmk Enterprise Edition 2.1.0p14
I want to create a view that displays all hosts that do NOT begin with a certain IP address.
For example, list all hosts that have an IP address not starting with 10.69.
I wanted to achieve this using Regex. Using Regex101, this expression would be the one I need: ^(?!10.69).*
Unfortunately, CMK sends an error when trying to apply this search pattern: Unhandled exception: 400: Filter: invalid perl operator: (?!
After further digging it seems like CMK is indeed unable to understand a lookahead pattern and the “solution” is to show a proper warning: https://checkmk.com/werk/11020
So is it correct that CMK does not understand all Regex patterns?
How can I now create my desired view [the IP addresses change, so placing hosts in certain folders or giving them tags would not be a permanent solution I guess]?
Hi
apparently RegExp are not fully supported/working as expected.
Its a mix of regexp and glob patterns if I remember cocrrectly
