Greetings,

I have modified the ps in all my clients so that it also sends out per-process cpu usage, and now am trying to use a regular perl expression in the search for processes with a certain usage percentage. Here is what i have:
%(8\d{2}\.\d{2})|(9[0-4]\.\d{2}) and %(9[5-9]\.\d{2})|(1\d{2}\.\d{2}) as 2 of my searches



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}".



OK -- i checked my rules, and realized that i typed them into the e-mail wrong -- here is a direct cut/paste
PROC %(8\d\.\d{2})|(9[0-4]\.\d{2}) 0 0 yellow
PROC %(9[5-9]\.\d{2})|(1\d{2}\.\d{2}) 0 0 red

After i pasted this i realized that i was also pulling IP addresses, so i changed the rules to this:
PROC %\s+((8\d\.\d{2})|(9[0-4]\.\d{2}))\s+ 0 0 yellow
PROC %\s+((9[5-9]\.\d{2})|(1\d{2}\.\d{2}))\s+ 0 0 red


Which now work, but seems to be acting strange because when it finds a bad process it reports this(keep in mind that these are sorted by cpu usage and nothing has been edited/cut out):

red %\s+((9[5-9]\.\d{2})|(1\d{2}\.\d{2}))\s+ (found 7, req. at most 0)

adam     18178 18176 99.63 11:19:16 pts/3       02:00 -bash
root        19     0  0.55  Nov  8  ?           05:29 vxfsd

so i am not sure where the "found 7" is coming from, when clearly there is only 1...

Thanks,
Adam

These don't work however, because they pull up everything that is 8.xx 8x.xx 9.xx 9x.xx 1.xx 1x.xx and 1xx.xx



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.
