The livestatus proxy daemon has been reworked to use a multi process
architecture. It now has a master process that mainly cares about
monitoring the site processes. Each connected site has an own subprocess
that manages all channels to this site and the clients that use these
channels to communicate with the sites.
When you have a look at ps/top you should see something like this:
OMD[heute]:~$ ps -ef | grep liveproxyd
UID PID PPID C STIME TTY TIME CMD
heute 9261 1 0 11:40 ? 00:00:00 liveproxyd[master]
heute 9262 9261 0 11:40 ? 00:00:00 liveproxyd[heute_slave_1]
heute 9263 9261 0 11:40 ? 00:00:00 liveproxyd[heute_slave_2]
As you can may see there is the master process that has the process 1
as parent process. The site processes have the master as parent.
When one site process terminates for some reason the master will restart it.
When the master is terminated all site processes will terminate too. In case
of a restart or config reload the master will restart itself and stop
all site processes and restart them again.
With this change the load of the livestatus proxy will now spread over
Side note: There is a new global setting Logging of the Livestatus Proxy
that can be used to control the detail level of the log entries written to the
var/log/liveproxyd.log log file. In case you experience any issues
with the livestatus proxy daemon take a look at this log file and maybe increase
the log level to get more details.
