Hi,
I need help with a webservice https check. Basically it worked in the past, but since we changed to use SSO (with keycloak in the background) on this server since a few days, the https check does not work anymore, and I don’t know how to correct this. This is the failed check:
this is the current http service check setting:
and here is my check on the cmd-line:
SAL@lnzcheckmk01:\[\~/lib/nagios/plugins\]> ./check_httpv2 --url https://lnzgrafana01.research.silicon-austria.com --method GET --onredirect critical --debug-content --debug-headers --verbose
