Hi,I also have fairly large filesystems running nominally with just a few gigs left. I also run into the percentage problem. Looking through the description in hobbit-clients.cfg, there seem to be a solution:
. . . # DISK filesystem IGNORE # If the utilization of "filesystem" is reported to exceed "warnlevel" # or "paniclevel", the "disk" status will go yellow or red, respectively. # "warnlevel" and "paniclevel" are either the percentage used, or the # space available as reported by the local "df" command on the host. # For the latter type of check, the "warnlevel" must be followed by the # letter "U", e.g. "1024U". . . .This would give us the possibility to test on explicit disk space. I tried configuring it (windows clients) but never got it right. Anyone else tried or is this not implemented yet? Could there be a formatting discrepancy from the windows client? I do see a difference between the capacity columns reported. In my setup, it is reported with % from the windows client and with 1k-blocks from unix clients. Could this affect the test?

If that's the case, a fourth color would have the same limitation ;-) (That's a lot of disk space if 100% full = gigs of free space) With the lack of a finer granularity, the only option you have is to create a custom script (client-side or server-side should work in this case) that checks the _amount_ (as opposed to _percentage_) of free space, and set a green/yellow/red threshold based on that. You could then set up the Hobbit alert rules like any other test, and it sounds like this would solve your particular problem. (a client-side script would probably be the easiest to set up, depending on how many machines it would need to be propagated to) On Fri, Jul 18, 2008 at 2:57 PM, michael nemeth <michael.nemeth (at) lmco.com> wrote:Sorry, disagree! I can have gigs of space left at 100% not critical at all !!!! Its not "beyond critical" its fatal if you hit zero free ! Either one needs finer granularity (isn't numerical limits in the work) or a new fatal color. I have licenses that run near 100 % all the time too. Gary Baluha wrote: The philosophy Hobbit uses for alerting is that you're okay until you reach a certain threshold. At that point (yellow) you still have to respond to the event and take care of it, before it becomes a bigger issue. If it continues, then you reach another threshold where stuff can (and usually does) break. At this point, you _need_ to respond to the event. What you are proposing is a fourth level such that you are "beyond critical". This is a similar concept to being "fatally killed" (as opposed to just being "killed"). The trick to running a successful monitoring system is setting the thresholds in the first place (which is easier said than done), such that you don't have any false-positives, but even more importantly, no false-negatives (i.e. an alert you should have gotten, but didn't). Can you give a more specific example (in as far as I.P./security will allow) of what you are trying to accomplish?

Meaning: One of my customers wants a setup like this: Custom script runs on client server, reports: foo : 80 for example. They want less than 85 to be green, 85-90 yellow, 90-95 red, and above 95 any color, say orange. So far as I can tell, I can only use green, yellow, and red for alerts, and blue and purple are reserved.Currently, no. But it might help to understand why 4 alert levels are desired. QUESTION #2:lets say #1 above is possible, so my script sends hobbit the status line based on the it sees, with the status of green, yellow, red, and orange. The hobbit server recieves it, and uses the NCV module to build the rrd etc.. In hobbit-alerts.cfg to say does the SERVICE keyword work for custom NCV type columns?The SERVICE tag in hobbit-alerts.cfg works for any column name, NCV or otherwise.
