Ok I have more info about the Issue with our D-link switches (D-link models DGS-1216T & DGS-1248T). One of the engineers has emailed me an explanation of the exact issue; if anyone can assist in a solution I would be very grateful.
The switches do support SNMP and Opsview can use some of the data that is available. The issue is that in Opsview, the check that measures traffic throughput on the individual ports isnt working. In Opsview there is an option to query the switch for all of it's interfaces, which works fine (using both SNMP v1 and 2c), all the ports and indexed and show up as expected. Usually one can then select a check box for each port if you want to monitor it. You then set a warning (80%) and critical level (90%) threshold for throughput on each port monitored. Unfortunately Opsview isnt getting back any data from the switch about how much traffic is passing through each port, so the alert will never be triggered. We tried to snmpwalk the switch from the Linux machine (which prints out all of the data available via SNMP) to try and find the correct SNMP MIB or OID, but could not find the relevant string that reports on traffic throughput for a port. The closest we could find was the interface speed which is, as expected, a fixed number depending on what the port is operating at (10/100/1000) so not much use for measuring traffic levels. Perhaps someone on the list can explain which MIB/OID they are using to gather this info as we couldnt find this (if it is there..) We also tried to query the switch using Cacti just to see if it could graph the ports but that also returned no results. Lloyds TSB Bank plc. Registered Office: 25 Gresham Street, London EC2V 7HN.
