Currently, varnishlog does not support very advanced filtering. If
you run it with -o, you can also do a regular expression match on tag
- expression. An example would be
varnishlog -o TxStatus 404to only show log records where the transmitted status is 404 (not found).
While in Brazil, I needed something a bit more expressive. I needed
something that would tell me if I had vcl_recv call pass and the URL
ended in .jpg.
varnishlog -o -c | perl -ne 'BEGIN { $/ = "";} print if
(/RxURL.*jpg$/m and /VCL_call.*recv pass/);'
fixed this for me.
