trigger expression is correct or not

[iftitutul]

item : Processor load (15 min average per core) system.cpu.load[percpu,avg15]

1. trigger: {Template OS Linux:system.cpu.util[all,idle,avg15].avg(60m)}<1
2. trigger: {Template OS Linux:system.cpu.load[all,avg5].avg(60m)}>( {Template OS Linux:system.cpu.num.last(0)}*3)

kindly explain it. is this trigger correct?

Hi,
What do you want to achieve?

1. trigger looks for the average cpu idle value for 1hour period and if it is more than 1 it will fire.
2. monitors average cpu load for 1hour and will fire if the value is more than 3*[number of cpus] (for example: if you have 2 cpu it will be evaluated against 6)

and yes triggers looks ok.
