How do I take the bbgen and bbtest headers out of the view for my clients? Thanks!

Well, I finally have file existence working with changing filenames. Thanks for the suggestion Charles. It wouldn't exactly work for me though since the files may never be created.
The documentation of client-local.cfg says "Putting wildcards directly into the file: entry will not work." But, you can do something like this:
file:echo /usr/local/scripts/logs/logfile.*
Since the beginning of the filename is always the same, doing the echo command on the filename still reported a name that Hobbit could check against.
Then, in the hobbit-client.cfg, I have this:
FILE %^\/usr\/local\/scripts\/logs\/logfile.* SIZE>1K
This checks that the file is there and that it's over 1K in size.
Thanks!

It won't work the way you are doing it now. You are using an ls command to dynamically create the list of files to check in your client-local, so when that file is missing, the ls command doesn't output it as a filename to check, so the test drops off when that file dissappears,
Since the files are dynamic, I assume created every day, you are going to have to figure out a way to tell if one of them goes away. Maybe you could have a cron job that runs every morning, and does an ls of the files and saves the output somewhere like /var/tmp/todays_files.txt, and then in your client-local you could do something like:
[hostname]
file:head -1 /var/tmp/todays_files.txt|tail -1
file:head -2 /var/tmp/todays_files.txt|tail -1
file:head -3 /var/tmp/todays_files.txt|tail -1
...
That would add a file entry for every line of todays_files.txt. So if one of the files got deleted, it would still be referenced in todays_files.txt, and thus continue to be monitored (including notification that it was no longer there).
That is a frightful way to do it, but I can't think of anything better at the moment :) Dealing with randomly generated filenames is a pain.

I found part of my problem of why the file existence isn't working. I wasn't specifying the full path in the hobbit-clients.cfg file. I also had to escape the forward slashes and underscores with backslashes. Plus, the "red" parameter wasn't valid from what the log said.
But still, I want to know if a file doesn't exist. The hobbitcleint.log file on the client just keeps saying
"ls: /usr/local/scripts/logs/dcsmnj8yecotnwbcevyym9t8c_4d7i*: No such file or directory". Therefore, it doesn't report anything about it. But I want to be alerted that it doesn't exist.
Is anyone successfully monitoring file existence?

Thanks Greg,
The filenames do change, they have the date appended to them. I'm wanting to check that the files are there and that they're not 0 bytes.
I know that when I was first setting it up I messed up something and it said "File missing" when it didn't find the file. Now it doesn't seem to care.

If the file names never change, then specify the file name in the client-local.cfg instead of running the ls command. If you delete the file, then the ls command will return nothing. That is what I would try first, anyway.
Or, it could be your check -- you are only asking for an alarm if the file size is bigger than 1K. A missing file is not bigger than 1K is it? And it seems like you need to do some other things as well to get this correct. I am working from memory...

Hi,
I'm wanting to check the existence of specific files in a directory and that they are at leat 1K in size. I have this in the hobbit-clients.cfg file:
HOST=hostname1
PROC httpd
FILE %^sdc_.* MTIME<3600 TIME=W:0730:2200 red
FILE %^dcs1xaz9saotnw713cmtaut8c_6w3j.* red size>1KTIME=*:0730:1800
FILE %^dcsaplg0kbotnwvrj16x28msg_1i2n.* red size>1KTIME=*:0730:1800
FILE %^dcsdq1p60cotnw32xcywlbisg_9i5q.* red size>1KTIME=*:0730:1800
FILE %^dcsmnj8yecotnwbcevyym9t8c_4d7i.* red size>1KTIME=*:0730:1800
FILE %^dcsp6ro5kbotnwvjh6yh0dmsg_3j1y.* red size>1KTIME=*:0730:1800
FILE %^dcsu5rokrbotnwb01tmd19mat_4w7s.* red size>1KTIME=*:0730:1800
And this in client-local.cfg:
[hostname1]
file:find /usr/local/webtrends/sdc/weblog -type f | xargs ls -1tr | tail -1
file:ls -1 /usr/local/scripts/logs/dcs1xaz9saotnw713cmtaut8c_6w3j*
file:ls -1 /usr/local/scripts/logs/dcsaplg0kbotnwvrj16x28msg_1i2n*
file:ls -1 /usr/local/scripts/logs/dcsdq1p60cotnw32xcywlbisg_9i5q*
file:ls -1 /usr/local/scripts/logs/dcsmnj8yecotnwbcevyym9t8c_4d7i*
file:ls -1 /usr/local/scripts/logs/dcsp6ro5kbotnwvjh6yh0dmsg_3j1y*
file:ls -1 /usr/local/scripts/logs/dcsu5rokrbotnwb01tmd19mat_4w7s*
They all show up under the files column. To test it, I deleted the file specified in the last line from the directory, but all Hobbit does is remove it from displaying. I want it to go red saying that the file does not exist.
The man pages says "By default, a warning is triggered for files that have a FILE entry, but which do not exist." But, I'm not seeing this occur.
Any ideas?
