Description: The elapsed time between the time the ICMP echo request is sent to the host identified by the index object icmpEchoReqHost and the time the ICMP echo reply is received at the agent host. The ICMP packet size and the time out to be used for the ICMP echo request are identified by the indices icmpEchoReqPktSize and icmpEchoReqTimeOut. See description of icmpEchoReqTable for more details.

In other words, the number of milliseconds it takes for an ICMP echo request to respond. Other return values: -1 if there is an internal error, -2 if the echo request timed out, -3 if the echo reply is not the correct reply, -4 if the packet size is too large, and -5 if the timeout is invalid.

To request the ICMP response time for IP address a1.a2.a3.a4 with a timeout of t and a packet size of s, send a request for icmpEchoReqTime.s.t.a1.a2.a3.a4.

For example, suppose one wanted to find out the number of milliseconds it took to ping 15.2.112.113, with time out of 8 seconds, and packet size of 75. Accordingly, icmpEchoReqTime.75.8.15.2.112.113 would identify the number of milliseconds.
