5342.0. "IP Poller info please........" by KERNEL::DAVIES () Thu Jul 15 1993 06:34


	Hi All,

	I have a question about the IP Poller.

	When you start the poller it asks you for the polling interval.  The
	default is 30 seconds.  Does this mean that each IP node is polled 
	every 30 seconds or will it poll all nodes one after the other and 
	then cycle again after 30 seconds delay??  I've heard that nodes 
	are polled in batches of 50.........is this correct?

	Could someone elaborate on how the poller exactly works.

	Cheers,

	Phil.

	If the polling interval is 30 seconds and it takes 20 seconds to poll all the nodes, then the poller will sleep for 10 seconds. Yes, the poller does poll 50 nodes at a time. It sends out 50 ICMP echo requests at a time and waits for the echo replies till the timeout period expires. If the number of retries are more than 0, then the nodes that didn't respond are polled again till all the retries are done. Rahul.
