Adding regex based rulesets to service groups

Troubleshooting
1

Hi All,

Hope everyone is safe and well.
I’m trying to automate the addition of regex based rulesets using the API, but can’t seem to find out why it fails. The return code for the curl result output doesn’t help because it doesn’t error out:
{‘result’: None, ‘result_code’: 0}*)

The used API command for troubleshooting is as follows:

curl “http://”$ipaddress":"$port"/"$sitename"/check_mk/webapi.py?action=set_ruleset&_username=automation&_secret="$automation_secret"&request_format=python&output_format=python" -d “request={‘ruleset_name’:‘service_groups’,‘ruleset’: {‘folder1/folder2’: [{‘condition’: {‘service_description’: [{’$regex’: u’App1_Log’}]}, ‘value’: ‘myservicegroup’, ‘options’: {‘description’: u’app1-log’}}, {‘condition’: {‘service_description’: [{’$regex’: u’App2_Log’}]}, ‘value’: ‘myservicegroup’, ‘options’: {‘description’: u’app2-log’}}]}}”

This results in check_mk erroring out on “gui” with :

KeyError (’$regex’)

Any help would be appreciated.

Hi all. His this forum active ?

Hi MTV,
did you try you API Call without unicode str e.g. [{’$regex’: ’App1_Log’}] or masking $ e.g [{’$regex’: u’App1_Log’}]
Cheers,
Christian

Hi ChristianM,

Finally got a hold of the problem, although your answer didn’t solve the issue.

The problem was on the URL and the strings that need to be passed, namely request_format and output_format.

Botth need to be ‘python’ and request_format MUST be after output_format.

Thank you nevertheless.

Cheers
