The number of milliseconds it takes for an icmp echo request to respond. ibmSNMPRemPing is -1 if there is an internal error, -2 if the echo request timed out, -4 if the packet size is invalid, -5 if the timeout is invalid, -6 if the IP address was not valid and -7 if the format of the MIB instance is not valid. To request the icmp response time for ip address a.b.c.d with a timeout of e and a packet size of f, send an snmp get request for ibmSNMPRemPing.f.e.a.b.c.d. For example, suppose one wanted to find out the number of milliseconds it took to ping address 9.67.30.4, with a timeout of 8 seconds, and a packet size of 94 bytes. Accordingly, ibmSNMPRemPing.94.8.9.67.30.4 would identify the number of milliseconds.
