I think you have an error in that first expression - the "8\d{2}" seems
wrong, if you want it to match number 80-89. It should be "8\d" without
the "{2}".

I'm not sure what data you're feeding it, but I tried with this setup in
hobbit-clients.cfg:

HOST=localhost
        PROC %(8\d\.\d{2})|(9[0-4]\.\d{2}) 0 0
	PROC %(9[5-9]\.\d{2})|(1\d{2}\.\d{2}) 0 0

This will give a red if any of the commands in the "ps" listing has the
percentages 80-94 or 95-100. Now let's test it:

$ bbcmd hobbitd_client --test
Hostname (.=end, ?=dump, !=reload) [localhost]: localhost
Test (cpu, mem, disk, proc): proc
ps command string: 82.31 ls
ps command string:
Process %(8\d\.\d{2})|(9[0-4]\.\d{2}) color red: Count=1, min=0, max=0
Process %(9[5-9]\.\d{2})|(1\d{2}\.\d{2}) color green: Count=0, min=0, max=0

Good, the ps commandline string "82.31 ls" is matched as it should be.

Hostname (.=end, ?=dump, !=reload) [localhost]:
Test (cpu, mem, disk, proc): proc
ps command string: 8.29 ls
ps command string:
Process %(8\d\.\d{2})|(9[0-4]\.\d{2}) color green: Count=0, min=0, max=0
Process %(9[5-9]\.\d{2})|(1\d{2}\.\d{2}) color green: Count=0, min=0, max=0

And the string "8.29 ls" is not matched. 

Hostname (.=end, ?=dump, !=reload) [localhost]:
Test (cpu, mem, disk, proc): proc
ps command string: 100.00 muncher
ps command string:
Process %(8\d\.\d{2})|(9[0-4]\.\d{2}) color green: Count=0, min=0, max=0
Process %(9[5-9]\.\d{2})|(1\d{2}\.\d{2}) color red: Count=1, min=0, max=0

"100.00 muncher" is also matched

Hostname (.=end, ?=dump, !=reload) [localhost]:
Test (cpu, mem, disk, proc): proc
ps command string: 1.00 low
ps command string:
Process %(8\d\.\d{2})|(9[0-4]\.\d{2}) color green: Count=0, min=0, max=0
Process %(9[5-9]\.\d{2})|(1\d{2}\.\d{2}) color green: Count=0, min=0, max=0

But "1.00 low" is now matched.


So either your rules are different from what I've used, or your ps
output is unlike that which I used. I think you'll need to post some
more details for us to figure out what the problem is.
