Reading the varnishlog¶
What do the lines in varnishlog output mean?
man vsl(7) for full documentation of the format and contents
of Varnish log tags (or see the online link, in this
case for current trunk, or for your Varnish version).
How do I filter varnishlog output to make it more manageable?
man vsl-query(7) shows you how to use VSL queries to pick out log transactions with contents you specify. See also man varnishlog(1) for command-line options that restrict the output for each transaction. Some useful ones are:
-i: only show log lines with certain tags
-I: only show lines matching a list of tags and a regular expression
-x: don’t show lines with certain tags
-X: don’t show lines matching a list of tags and a regular expression
Multiple options are allowed on the command line for each of these.
