my distributed monitoring is almost done. Now I am trying to secure it with HTTPS. Since we have a wildcard certificates, I had to set a CNAME for the master and the slaves to match this wildcard certificate. I configured apache on one slave to redirect to the CNAME with HTTPS and it works as expected. On the master I adjusted the slave configuration, so I set the URL prefix to the CNAME with HTTPS under Livestatus Settings and the Multisite-URL for the replication configuration with the CNAME and HTTPS as well.
Now when I go to Analyze configuration it still shows Warning to consider using HTTPS instead of HTTP under the Security section. It seems it needs more than what I’ve done to get this working!
I am using check-mk-raw 1.5.0p7 on Ubuntu Xenial.
