Zabbix http poller processes more than 75% busy - How do I resolve this alert?

[jornell]

Hello, Some time ago I got the following alert "Zabbix http poller processes more than 75% busy".





I have zabbix 6.0 on Ubuntu 20, and I should have plenty of resources for the number of servers that are being monitored,
If anyone knows what this alert means and how to solve it, I would be very grateful.

Hi,

You need to find this section in your zabbix server configuration file (zabbix_server.conf):

### Option: StartHTTPPollers
#    Number of pre-forked instances of HTTP pollers.
#
# Mandatory: no
# Range: 0-1000
# Default:
# StartHTTPPollers=1

As you can see, "StartHTTPPollers" default value is "1". You can increment it to "2" and restart zabbix service.

I cannot suggest you to increase it too much in one shot. If "2" is not suffient, increase it a little more. After that, that trigger should be closed.

Best regards
