Trigger expression too long

[mbrijun]

Hello,

I am having a bit of a difficulty trying to create a complex trigger that checks that a service is running only on one of three possible servers. The resulting expression is too long and the trigger dialogue window refuses to take it.

Any hints would be much appreciated

Post your trigger so we can have a look.

Hi Erisan,

thank you for your reply. The trigger is like this:

({NYCMWSBE03:service_state[MWS_CalScheduler].last(0)}+{UKIGMMWSBE02:service_state[MWS_CalScheduler].last(0)}=0)|({UKIGMMWSBE02:service_state[MWS_IGMScheduler].last(0)}+{SINMWSBE01:service_state[MWS_CalScheduler].last(0)}=0)|({NYCMWSBE03:service_state[MWS_CalScheduler].last(0)}+{SINMWSBE01:service_state[MWS_CalScheduler].last(0)}=0)

I was thinking of taking advantage of the fact that when the service is stopped, it returns the value of 6. By summing up the service_state values of all three servers, the sum will be less than 12 if two instances of the service is running. However, this has a potential problem - a service can be paused, and it will return a value of 1, and that will cause the trigger to become TRUE.

Thanks,
Martyn
