Need help with trigger dependencies

[moshikoy]

Hi,
My goal is to monitor idle user processes
So i wrote discovery rules to find the processes and monitor their usage (by reading vmsize,cputime and context.

I'd like to be able to trigger for idle process that are running for 3+ days, 4+days, and 5+ days

3days trigger
{Process discovery:custom.ps.etimes[{#PID}].last()}>259200 and
{Process discovery:custom.ps.vmsize[{#PID}].delta(259200)}=0 and
{Process discovery:custom.ps.cputime[{#PID}].delta(259200)}=0 and
{Process discovery:custom.ps.context[{#PID}].delta(259200)}=0

4days trigger (Depends on: 3days trigger)
{Process discovery:custom.ps.etimes[{#PID}].last()}>345600 and
{Process discovery:custom.ps.vmsize[{#PID}].delta(345600)}=0 and
{Process discovery:custom.ps.cputime[{#PID}].delta(345600)}=0 and
{Process discovery:custom.ps.context[{#PID}].delta(345600)}=0

5days trigger (Depends on: 4days trigger)
{Process discovery:custom.ps.etimes[{#PID}].last()}>432000 and
{Process discovery:custom.ps.vmsize[{#PID}].delta(432000)}=0 and
{Process discovery:custom.ps.cputime[{#PID}].delta(432000)}=0 and
{Process discovery:custom.ps.context[{#PID}].delta(432000)}=0


There is something that is not right with the triggers, I can see all 3 days trigger alerting. however 4days and 5days triggers are alerting and being resolved after a short while

Feels like a logic issue with the dependencies
