For list: Information about Notification Threads
The number of Notification Threads that get used by the system at any one time, is proportional to the number of attribute or watch changes occurring on the network. Once a network is up and has achieved stability, the number of Notification Threads required to monitor the system should remain steady and small. When the number of notification log threads needed exceeds the number of notification threads available, then pending notification thread requests are queued until a notification thread becomes available. If the number of notification threads available has been exceeded, then the number of notification threads may be insufficient for the current state of the network.

Do you know by chance what "Notification Thread" means and what causes spectrum to increase this number? From: HUNGERFORD, CLIFF [AG/1000] [mailto:[email protected]] Sent: Thursday, March 04, 2010 10:06 AM To: Lalit Tyagi Subject: RE: [spectrum] Spectrum Latenecy The first place I would check is to make sure your notification threads aren't being maxed out. You can see this under the Information tab for the SpectroSERVER model in OneClick. I have my available notification threads set to 600; I believe the default setting is somewhere around 100. You may have to increase your total pool of available threads, and be sure to keep a careful watch on your CPUs after adding available threads, to ensure you don't overtax the CPU. Also, check to make sure that there isn't an old process still running that shouldn't be. Are you running Windows or Unix/Linux? From: Lalit Tyagi [mailto:[email protected]] Sent: Thursday, March 04, 2010 8:41 AM To: spectrum Subject: [spectrum] Spectrum Latenecy Hi List, We are using spectrum 8.1 (SP2) in our environment. Last week, spectrum was crashed and then we restarted spectrum server. Since then, spectrum working fine but having lot of delays in discovery any device, putting device in maintenance or getting device unreachable alarm. I have checked SS Performance table which shows Notification Latency around 800 sec. Does any one faces this problem? Any idea, how could I possibly check why spectrum having so much delays?
