When I install the above mentioned module, though it does show successful installation, it is not apparent in the GUI. Please see proof of installation:
However, when I try to check the statistics set-up, the SQM table is not available. I have installed already other metrics in processor load, interfaces, wireless, and so on and already configured it via ssh. Perhaps it was a mistake to not include the SQM table in with the other modules when I was doing so via ssh?
The data collection part with collectd works, but the support for SQM graphs has not been backported to the old 19.07 branch. Graphs are only in 21.02 and master.
