If one has a remote spark gap to be observed, the low-tech way
is to rig a couple of shaving mirrors in such a way that
the gap is brought into view.
An even lower-tech approach is to cover one of the gap
electrodes with a little "condom" of paper (forgive the
allusion). If the condom is later found to be
perforated or charred the conclusion is obvious.

The high-tech way requires a little handiness with elec-
tronics: A photocell and associated circuitry can be
rigged to light a lamp or give other indication when the
light from a spark is detected. The signal can even in-
crement an electronic counter to indicate how many times
the gap has fired.
The better commercial frequency counters have a
"period" function. Such can be employed
to obtain an indication of how many times per
second-minute-hour the gap is breaking down.
Radio Shack stores sell suitable photocells. They also
sell elementary electronics books which have starting-point
circuit diagrams for applying the photocells. Be certain
to shield =everything= exceedingly well for use near an
operating Tesla coil.
