increase respond time when a node down

Hi all,

I'm a newbie and I have some problems, please help me! Thanks in advance!

I want to increase respond time when a node goes down. For example as soon as it goes down, the monitor event will notify me

I've changed the ICMP timeout downto 200ms but the fastes time when monitor event detect a node goes down is about 1-2 minutes

Please help me!

Hi,

You might want to increase the Node Warning Interval to something higher than 2 minutes:

In System Manager:

File > Advanced Settings...

Select the "Node Warning Interval".

Change the settings and click on Ok.

HTH,

Changing the ICMP timeout will not do this. What you want to do is change the Polling interval for icmp. This can be done on a device by device basis or globally through System manager. To do it for an individual node you would open system manager and right click on the node selecting node details. To do it globally you will want to open system manager Select File->Network Performance Monitor Settings and select the Polling tab. From there change the Default Poll Interval for Nodes and apply those settings to all. One thing to keep in mind is that as you poll more frequently, the max number of elements you can poll on a single polling engine will decrease.

Hi all,

Thank for all of your supporting. I've done all things you said, and I think I've reached the limit of NPM. May be it can't respond faster ^_^

Btw, thank you very much!
