Diagnosing problems with your multicast setup | Contributed code and patches


Blind Beacons -- These Beacons are being correctly reported to the Central Server, but do not see any other Beacons, nor are they seen by any other Beacons. Check your multicast setup if you are the admin for any of the Beacons listed below!

Central Loss is the reported loss between two Beacons in the current multicast group, sent via TCP unicast back to the Central Server (in this case, "jhereg.ncsa.uiuc.edu") for the group. This allows for the reporting of Beacons that might not otherwise be able to see each other via UDP multicast.

The "RRs" column is the count of RTP Receiver Reports received from each SR during the previous interval. For any given interval, the count of reports should be approximately the same. If your Beacon's report count is much lower than the others, it means your Beacon has only recently joined the multicast If you know you Beacon has been running for some time, it may be showing router-level multicast problems, which is why the option was included in this release of the Beacon. If your Beacon is joining and leaving and joining and leaving, this it what that would look like.
