template import errors

[chubbz327]

Hi All

I have a template which has items, triggers, and graphs,
The items import without issue but i am getting the following error on the trigger expressions:

Empty item key "" is used in expression. Check expression part starting from "{{HOSTNAME}:jmx[Catalina:type=ThreadPool,name=ajp-10.0.0.99-8080][currentThreadsBusy].last(0)} > ({{HOSTNAME}:jmx[Catalina:type=ThreadPool,name=ajp-10.0.0.99-8080][maxThreads].last(0)} *0.7)".


xml fragment below:

<trigger>
<expression>{{HOSTNAME}:jmx[Catalina:type=ThreadPool,name=ajp-10.0.0.99-8080,currentThreadsBusy].last(0)} &gt; ({{HOSTNAME}:jmx[Catalina:type=ThreadPool,name=ajp-10.0.0.99-8080,maxThreads].last(0)} *0.7)</expression>
<name>70% ajp-10.10.17.93-8080 worker threads busy on {HOSTNAME}</name>
<url />
<status>0</status>
<priority>2</priority>
