Dear All, Christophs idea is a good one, but there could be one downside: one would need to run Policy Manager on a rather short interval. If Christians scenario happens often it might be worthwhile testing it out. If it happens only at random, its a trade off resources for Policy Manager vs. timely information.

April 2013 11:33 To: spectrum Subject: AW: [spectrum] Dynamic Polling Hi Guys, another idea: If one device is not responding any more, the attriute Contact Status will become 0 (Lost). Build a Real-Time GC with the filter and all devices will be collected. Then use the Policy Manager on this GC, to configure the poll and retry attributes for your needs. Spectrum will e.g. decrease the poll period and starts polling those devices more often. If the device model will be reachable again, It will disappear from the GC and you need another policy to reset the polling time etc. Regards, Christoph Von: David Game [mailto:[email protected]] Gesendet: Donnerstag, 25. April 2013 12:23 An: spectrum Betreff: RE: [spectrum] Dynamic Polling As I understand it, when a device is in critical state (Device has stopped responding to polls) Spectrum will attempt to ping it every 60 seconds to see if it replies, until the next scheduled SNMP poll. If it receives a ping reply, itll SNMP poll again straight away. If you have devices down for 3 mins at a time you could look to increase the DCM retries and DCM timeout for those devices to take account of this, alternatively theres an attribute you can set which determines how often its tested when down but I cant recall which one it is (I *think* pollingmultiplier or something like that?) Its in the documentation somewhere but I dont have it to hand right now. Jasons idea of a GC and event rule is also a pretty good one. David K.

I was asked whether it is possible, and I quote, "to manage devices that tend to be unresponsive for short periods of time, but nevertheless with a reasonable way of getting to know what state the device is in". In other words, we do not want to be BOMBED with ten alarms an hour because the device is unresponsive for three minutes, but always be able to say, yes, it's up again. Discussing the idea, I was unable to answer the following question: In what intervals does SPECTRUM poll an unresponsive device? It is clearly more often than in normal operation, for there are alarms that last less than our 30 seconds standard polling interval. Some tests with varying intervals lead me to the conclusion it is roughly half the configured polling interval. Might this be true? And, more importantly: Can it be configured? In easy words, I need to poll a device once an hour, but once SPECTRUM has detected an outage, I definitely need to know when the device comes up again, and not eventually after 30 minutes. Things like SPM and EventDisp customizing have been discussed already. Due to the dynamic nature of the amount of models affected, it must be an attribute based solution, i.e. something ouf of the box. Thanks a lot for your thoughts!
