How can I get max value of system.cpu.util, NOT avg?

[EvilEugene]

Hello all!
one of my colleague request me to build monitoring system that can catch CPU peak in 5 seconds.
so I did change item interval in zabbix web gui, to 5s, but I realize that the zabbix agent returns data as '1min average', not 'max'.
I did googled but I can't find how to change this behavier.

Is there any workaround about this? or, should I make some custom script?

thanks.

I think you are going to want to use a calculated item. There are some examples in the documentation.

I just simply modified zabbix_agentd source.
now my zabbix_agent send data which 'collected in seconds', NOT 'average of 1 minute'.

I changed these things :

/src/zabbix_agent/cpustat.c :
    added mode ZBX_SEC1, ZBX_SEC5

/src/libs/zbxsysinfo/linux/cpu.c
    added mode ZBX_SEC1, ZBX_SEC5

/include/sysinfo.h
    added define for ZBX_SEC1 and ZBX_SEC5

It's enough for now.
