I am trying to add some rules for our esxi 5.5 servers.  Im am seeing some 
predecoder behaviour I dont understand. in two nearly identical messages 
the precoder give me different results

For the following message
2014-12-30T06:39:20.007Z cpu16:747537)World: 14302: VC opID hostd-b7af maps 
to vmkernel opID 7905d78d

the precoder returns

**Phase 1: Completed pre-decoding.
       full event: '2014-12-30T06:39:20.007Z cpu16:747537)World: 14302: VC 
opID hostd-b7af maps to vmkernel opID 7905d78d'
       hostname: 'SawMill'
       program_name: '(null)'
       log: '2014-12-30T06:39:20.007Z cpu16:747537)World: 14302: VC opID 
hostd-b7af maps to vmkernel opID 7905d78d'

However if there is only a single digit after the "cpu" string such as the 
following message that is identical to the first except for "cpu16" -> 
"cpu6"

 2014-12-30T06:39:20.007Z cpu6:747537)World: 14302: VC opID hostd-b7af maps 
to vmkernel opID 7905d78d

**Phase 1: Completed pre-decoding.
       full event: '2014-12-30T06:39:20.007Z cpu6:747537)World: 14302: VC 
opID hostd-b7af maps to vmkernel opID 7905d78d'
       hostname: 'SawMill'
       program_name: '7537)World'
       log: '14302: VC opID hostd-b7af maps to vmkernel opID 7905d78d'

Any recommendations to get consistent behaviour ?   Any recomendations on 
ESXI messages?

Bill
