Multicast sensor

Hello Kike
Thanks for reaching us.
Can you provide us with the device brand and model you are trying to monitor?
Also if this device supports SNMP?

First of all, thank you very much for caring to help me.

I have PRTG monitoring a network with Cisco switches and routers and HP servers with Windows Server, both in snmp and wmi.

One of these servers publishes a multicast PGM list with the format "239.255.1.X:Port" and what I would like is to be able to count, and therefore control when one of the publishers stops.

I've seen some, such as these:

• ifHCInOctets (.1.3.6.1.2.1.31.1.1.1.6)
• ifHCOutOctets (1.3.6.1.2.1.31.1.1.1.10)
• ifHCInMulticastPkts(.1.3.6.1.2.1.31.1.1.1.8)
• ifHCOutMulticastPkts(.1.3.6.1.2.1.31.1.1.1.12)

but I don't see that they can be configured to listen to a specific IP and ports, as I need

Best regards

Hello Kike I hope you are doing fine today
Regarding your question, PRTG will only be able to monitor these OIDs If the device supports the type of monitoring that you would like to implement. In short, If this server has a native (build in) feature that could tell you multicast queues are transmitting, "Or" if this transmission is going out on a particular Interface, then PRTG could install a sensor on that interface and monitor the traffic going out.
We don't have a native tool for this, but some of our customers monitor Multicast using the SNMP custom sensor or the SNMP traffic sensors
