Please, Dojo - I'm trying to detail the exact behaviour of a CUBE client connecting to a DMA via
.NET-Remoting>Eventing (this to facilitate FW configs).
On connection to a DMA, I seem to get at least one connection established, however the client switches to polling mode.
The output of a netstat on the client would show something like this:
It seems the ports in the "high port range" (49152 through 65535) are allowed on the client - the connection is actually "ESTABLISHED" to port 8004 of the server - via client port 51134, but then why the client has a second connection open in "TIME WAIT" and eventually switches to polling?
Is more than one port required on the client for eventing?
Or could the server be configured to use polling regardless of the connection successfully established between client port 51134 and server port 8004?
Cube settings for the above test were like this:
Any steer will be helpful
Need to resume testing on this – I seem to have different numbers of connections depending on the environment – I will update the thread as soon as I gather some more data
Hi Alberto,
I see that this question has been inactive for a long time. Do you still need more information about this? If not, could you select the best answer to indicate that no further action is needed here?
As this question has now been inactive for a very long time, I will close it. If you still want more information about this, could you post a new question?
Alberto,
You can configure Cube to only use polling see (Eventing or polling | DataMiner Docs). This is less performant but should align with what you are trying to achieve if I understand correctly?
Thanks, Rene
We’re trying to move away from this set-up, as clients don’t seem to cope very well while handling the polling required to handle alarms during storms.
Long story short, I believe this was a shortcut that was used when the monitored network was sufficiently small, but it is way bigger now, so we’d rather restore the eventing mechanism as the default behaviour, so that the load on the server doesn’t increase linearly (on SLNet) with the number of connected clients.
