The upstream vncviewer now has a very nice performance statistics graph. It would be nice if it could be available to ThinLinc users as well. For this, at least 2 things are needed: 1) Need to vendor drop upstream master 7cb4f31f6290df318962226bb35f60d0e2fd975c (2017-02-24 or later), or cherry pick this work. 2) Provide a way of activating this graph, through tlclient command line and/or GUI. Unfortunately, the only way of activating this in vncviewer is to run with loglevel 100, which might be too much. See upstream report: https://github.com/TigerVNC/tigervnc/issues/561 Also, currently we do not change the vncviewer loglevel based on the tlclient level (which is strange, because we do this for most or all other subprocesses).
We need some more details on the use cases here. What kind of monitoring or debugging are the customers trying to do? We've had one customer try this out, so we can follow up with them how useful it was for them.
New build of trunk with this feature is now available from: https://www.cendio.com/~astrand/thinlinc/b7093 (but no directory listing due to SELinux). It is activated by running "tlclient -d4". Trunk was patched by running: <cd Tigervnc> $ git diff master@{2017-02-08}..7cb4f31f6290df318962226bb35f60d0e2fd975c > ~/foo.patch <cd ctc> $ patch -N -F3 -p1 < ~/foo.patch One conflict had to be resolved manually.
The dev meeting has decided that this is a useful feature, which we should add. However, we need to think a little bit more on how it should be activated (ie use -d4 or some other solution). We also need to write at least some basic documentation.
We will not be rolling this out as is. The current graph is too low level to be useful and will probably mislead more than it helps. We need more tangible information about the needs here before we can start looking at how we can provide useful measurements.
