Zabbix ICMP pinger processes more then 75%

The default installation of Zabbix starts a limited number of pinger processes and they can get used quickly on larger networks.

To solve this problem, you need to open the zabbix server configuration file via nano

sudo nano /etc/zabbix/zabbix_server.conf

Next, find the parameter StartPingers in it, it’s down near the end of the file, if it is 1 and commented out, then you can increase it for example by 5 and uncomment (remove the # symbol before it).
Doing this increases the number of processes performing ICMP Ping, accordingly the load will be distributed and reduced.
Save your changes on exit

After the manipulations, you must reboot the Zabbix server with the command:

service zabbix-server restart

Also, the load can be reduced by increasing the “Update interval” in the template parameters. To do this, go to the Zabbix Web interface under the administrator and click Configuration – Templates, select the “Data items” on the required template, open the ping data item and find the “Update interval (in sec)“. 3 Minutes should be fine.
