Janice, In relation to the contributed probes, unfortunately I don't always have time to read my InterMapper Talk e-mail but that sounds like a good idea. I think it might also be helpful to have the date the probe was added/updated on the User Contributed Probes page. http://www.intermapper.com/support/user-contributed-probes

I am thinking that we need to build a probe using the SNMP high threshold, however, I can't seem to figure out the proper variable. Anyone doing this type of alerting, is there a better way? -------------------- m2f -------------------- Read this topic online here: http://forums.dartware.com/viewtopic.php?p=2098#2098 ---------------------------------------------------------------------- Subject: Fault isolation and map status probe thresholds From: "Stempien, Dave" <[email protected]> Date: Wed, 6 Jan 2010 15:38:32 -0500 All, I have been a user and champion of InterMapper for over 10 years. In my current organization, there is a very real chance that InterMapper could serve as our primary NMS. Currently, InterMapper is referenced as a "backup" to our primary NMS, Spectrum. I maintain InterMapper in parallel to helping maintain our primary NMS. InterMapper doesn't take much care and feeding beyond moves/adds/changes and hiding the extraneous newly-discovered interfaces that magically show up on maps. There are a few items on our desired features list that I wish I could defend InterMapper against. Unfortunately, I can't. Perhaps some of you might be willing to offer your advice on the following two items? Fault Isolation How are you handling fault isolation and notification suppression, especially in multi-homed networks? The "vantage point" solution has been useless for us. Our current NMS, Spectrum, handles fault suppressions well and automatically. If InterMapper is ever to replace Spectrum as our NMS, I need suppression of notifications to work better. Our engineers get cranky when they are awoken in the middle of the night from errant and extraneous pages. Even the ability to set manual dependencies would be welcome. Map Status Thresholds Suppose I have a map status probe for a map that contains 2000 wireless APs. I don't want a critical notification for the map status probe if only one of that map's devices goes down (or into alarm/warning/etc). I wish there could be a way to say, "set critical alarm if 100 devices within this map are down", or, "set warning if 10% of devices within this map are down", or something else to that effect. That would be very useful. As it is, we're forced to receive a critical notification each time a device that we deem to be low priority, such as APs or desktop switches, goes down. For these devices, I only want to receive notification for a major or catastrophic condition.

I've split your question into two, so we can keep the two threads separate. --- You wrote: Fault Isolation How are you handling fault isolation and notification suppression, especially in multi-homed networks?

(Would it be possible to get a screen shot?) I'll definitely look at what Spectrum does. Are there other systems that "do it right? I look forward to feedback from everyone on IM-Talk. Thanks.

Are there other use cases/places you would use something like this?

The Nagios check_multi plugin looks like a good conceptual starting point for a custom map status probe: InterMapper provides some basic variables (total devices + number {OK, warning, alarm, critical, down, unknown}) and probe writers set up appropriate parameters, calculation variables & conditions the same way we do for SNMP probes. Something could be cobbled together to fill the immediate need using the new API in 5.2 (ugly perl + command line probe) but I think an integrated map status custom probe type in a future version would be a good addition... -MG ---------------------------------------------------------------------- End of InterMapper-Talk Digest ____________________________________________________________________ List archives: http://www.mail-archive.com/intermapper-talk%40list.dartware.com/ To unsubscribe: send email to: [email protected] ____________________________________________________________________ List archives: http://www.mail-archive.com/intermapper-talk%40list.dartware.com/ To unsubscribe: send email to: [email protected]
