Policies: “AND” rule

[ablwr]

Users would like to generate policies based on each other, and also be able to see graphs and values compared against each other (“AND” policy).

:+1: This would be really great to have. I haven't ran enough tests to see if Signalserver would catch enough errors without this, but I'm familiar with interpreting spikes in multiple graphs in the QCTools GUI so I'd love if this was included.

okay will do!

Actually, can you tell me what kind of example? Right now signalserver is treating all filter separately. So I am not sure how I can give two conditions at the same time. I may be able to come up with something after I see the document @ablwr uploaded. (Example policy.) But for the meantime, an example would be great. Or do you actually want a graph not separate by the filter?

Example could be : TOUT > X & PSNR.Y > Y. This would, for example, show when the frame has many dropouts or speckle while the fields become more different, which would possibly indicate a head clog rather than tape damage.
