How to monitor Apache?

Question

Apache HTTP Server

Please help me configure Apache monitoring.
Debian is on the web server, Ubuntu is on Zabbix, I set it up according to the instructions blog.bissquit.com/?p=499
and does not plow, from the Zabbix server server-status is visible
zabbix_get for Apache gives an empty time, and for the CPU it shows
[email protected] data -zabbix:/tmp$ zabbix_get -s xxx.xxx.xxx.xxx -k "apache2[accesses, http://xxx.xxx.xxx.xxx/server-status] "
[email protected]:/tmp$ zabbix_get -s xxx.xxx.xxx.xxx -k "system.cpu.load[all,avg1]"
0.070000

Answer 1

Try adding the parameter to the zabbix-agent.conf config :
UnsafeUserParameters=1

Answer 2

Look in the zabbix-agent and apache log, maybe the server-status is given only for 127.0.0.1, and you are accessing it through the external interface.
