Problem with Zabbix Monitoring

[gandalf123]

Hello,

I have been using Zabbix for network monitoring for over a year. I installed Zabbix on an Ubuntu server with Maria DB and Apache.
Zabbix works fine so far, but sometimes the following problem occurs:
Zabbix sends me a whole series of error messages that some SNMP devices and agents can no longer be reached via ping, at the same time the messages come that all problems are solved again.

This happens sometimes every 4 weeks and then again every day. What can that be and how can I solve this problem?

Many thanks for your help.

Hi! The ping is a simple check executed from the Zabbix server or proxy. If you receive messages about ping, you need to check the network availability between the server(or proxy) and your devices. Maybe you have firewalls or provider's networks between them and they have temporary issues or planned maintenance.
