How many ICMP packets per second is not a flood?
| Posted by akbsol, 10-23-2010, 01:40 AM | | Hi everyone,
I need to monitor about servers + vpses + websites about 170 in total of my own people (on their request) at 1 min intervals. I have my own program which does this for about 20 servers at present through ICMP ping requests. At every minute I will be sending about 4 packets to each of these 170 servers. As these servers are on different networks and only 4 packets per minute and being sent to them, I don't worry much about the receiving side. But I do not wish to saturate the network of my sending server. Can anyone suggest me how much minimum ms delay should I put between each packet so that its not considered a flood and doesn't deteriorate the network or involve any restrictions at the sending router end.
-Regards,
Akash
