Issue :
Running Wily with SPS, then you have some Proxy rules
fired metrics reporting "Unknown=17"
in investigator.
Environment :
SPS 12.52SP1CR04 on Linux;
Resolution :
You have to set a PID for each rule in order
to get differentiated statistics per rule.
"Unknown" means there is no "pid" assigned to the rule.
You have to check your proxyrules.xml file.
Each rule should have a PID defined, if not, when the URL will be
requested, then it will be marked as "unknown" :
<nete:cond type="uri">
<nete:case value="/FormsAuth/file001.html">
<nete:forward pid="PR1">http://myhost.ca.com:1024$0</nete:forward>
</nete:case>
you'll get them the metric as "PR1=17" which means proxy rule PR1 has been hitten 17 times
