If you just want to know that 503s are happening at all, you can monitor
varnishlog for "NNN TxStatus c 503", although that won't tell you which
URL got the 503.

For that, it gets a bit tricky, you'd have to first watch for "NNN RxURL
c /some/path", and then watch for "NNN c TxStatus" with the same NNN,
emitting an alert for 503 and forgetting the URL otherwise.

At any rate, monitoring the varnishlog is the way to do this, we
wouldn't the Varnish demon itself to start sending email.


Best,
Geoff
