Thanks for your work! Merged :+1:

The only other thing I noticed. The following lines always appear in the log! If I am on the status page.

Fri Oct 28 12:37:24 2022 daemon.info Keepalived_vrrp[17362]: Printing VRRP as json for process(17362) on signal
Fri Oct 28 12:37:29 2022 daemon.info Keepalived_vrrp[17362]: Printing VRRP as json for process(17362) on signal

Fri Oct 28 12:37:34 2022 daemon.info Keepalived_vrrp[17362]: Printing VRRP as json for process(17362) on signal

This spams my log! I think this should get fixed in the keepalived packages? Maybe by change the log level? https://github.com/acassen/keepalived/blob/master/keepalived/core/main.c#L1794
