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, it'll 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 there's an attribute you can set which determines how often it's tested when down but I can't recall which one it is (I *think* pollingmultiplier or something like that?) It's in the documentation somewhere but I don't have it to hand right now. Jason's 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!
