Zabbix--Zabbix discoverer processes more than 75% busy

I am not familiar with linux, only know that zabbix is to do monitoring.

So after deployment, Zabbix discoverer processes more than 75% busy

This alarm has bothered me all day, and many articles on the Internet have not been thoroughly dealt with, or the specific principle has not been explained (it may be my personal problem)

Discoverer processes: the process of automatic discovery

This alarm is caused by the full process of auto-exploration / auto-discovery.

The StartDiscoverer parameter of the configurable zabbix profile is resolved.

But how good should this value be? What is the relationship between automatic discovery and this value?

Personal case:

1. Examination:

Such as the following figure: it is observed that the peak hours are fixed, that is, there is a scheduled task in a certain period of time.

2. Definite diagnosis:

Figure below: find a scheduled task, execute it every hour, and automatically explore a certain IP segment. The alarm problem is solved after the exploration rules are disabled.

3. Suggestions:

As shown in the following figure: check the value of related exploration on the Internet (no personal test)
