View source for Risolvere il problema Zabbix poller processes more than 75% busy

Occorre aumentare il numero di processi poller e le connessioni relative al DB per tentativi.

* Impostare prima mysql, altrimenti il server zabbix va in crash perchè non riesce più a conettersi. Aggiungere al valore già configurato quello dei poller che si imposteranno (il valore iniziale era 100):

 vi /etc/mysql/my.cnf

 max_connections        = 350

 systemctl restart mysql

* Impostare i poller in Zabbix:

 vi /etc/zabbix/zabbix_server.conf

 StartPollers=250

 systemctl restart zabbix-server.service

* Se il messaggio riguarda i poller proxy:

 Zabbix proxy poller processes more than 75% busy

 vi /etc/zabbix/zabbix_server.conf

 StartProxyPollers=10
 StartPollersUnreachable=10

 systemctl restart zabbix-server.service
