Tubes and their problems

I thought since I am currently having a few tube problems, and since i am not
that technically inclined, I would ask what are the typical warning signs and problems of our beloved tubes.
I will start off with the "popping" sound that I believe indicates either tube failure or impending failure ( perhaps someone can clarify why a tube does this?) What are the other various warning signs to look out for?

I heard popping from my Jolida FX-10's tubes on my right speaker. To see if it was the tubes, I swapped all the tubes from left and right channel and visa versa. The popping then happened on the Left side.

This proved it was the tubes - I went ahead and replaced all of them, fixing the problem.

If you do the swapping as mentioned above, and the popping continues on the same channel, then it's Not the Tubes.

Atmasphere, you're right, but I just went ahead and replaced all 6 tubes (which were Electro Harmonix and Tung Sol) with matched and cryo'd JJ's.
