2、zabbix Too many processes on xxx

The reason for the error: The
default traffic limit of zabbix is ​​300. When the number of processes of our server is greater than 300, the package name will occur. Here we can adjust Too many processes on {HOST.NAME} to modify the value to 3000 (based on our own server performance definition ), the original value is 300.

Then go to the dashboard to see that the alarm is no longer available.
