Trigger syntax

[huntp]

Hi, I'm trying to write a Trigger which tells me if my JVM PermGen memory has reached 70% of total available.

I've created a trigger with the following syntax, but it doesnt seem to fire ... am I missing some parenthesis or something?

{Template_JVM_Memusage:jvm.permgen.used.last(0)}/{Template_JVM_Memusage:jvm.permgen.commit.last(0)} >10

Though I lack the knowledge of the usual values for permgen.used and permgen.commit,
how come a relationship between them being confronted with a 10 ratio threshold expresses the 70% rule you described?

Shouldn't it be,

{Template_JVM_Memusage:jvm.permgen.used.last(0)}/{Template_JVM_Memusage:jvm.permgen.commit.last(0)}>0.7

Apart from the 10% vs. 70% bit, I think you need brackets around the first part of the trigger, like this:

({Template_JVM_Memusage:jvm.permgen.used.last(0)})/{Template_JVM_Memusage:jvm.permgen.commit.last(0)} >10

Basic maths, Brackets get done before the division!
