Zabbix 4 Network Monitoring - Third Edition

CPU discovery

Yet another discovery method supported by the Zabbix agent is CPU discovery. It returns all CPUs (or cores) present on a system. Now that we know how to get the LLD JSON, we only need to know which item key is used to return CPU information—that's system.cpu.discovery. Run this on A test host:

$ zabbix_get -s 127.0.0.1 -k system.cpu.discovery | json_pp

For a single-core system, it will return this:

{ 
   data : [ 
      { 
         {#CPU.NUMBER} : 0, 
         {#CPU.STATUS} : online 
      } 
   ] 
} 

The CPU discovery returns two macros for each discovered CPU:

• {#CPU.NUMBER} is a CPU number, as assigned by the system.
• {#CPU.STATUS} tells us the CPU's status, again, according to the host system.

This can be used to monitor various states on individual CPUs and cores. ...
