Past Articles:convert varnishlog output to easy

Changes

mapping from vcl_trace to vcl source(line).

if you set to -f option, replace vcl_trace to VCL code
before.
[code=’plain’]
| trace | vrt_count:1 vcl_line:55 vcl_pos:1
[/code]

after(use -f and -e option)
[code=’plain’]
| trace | set req.http.X-TEST1=campur_xcir.gethash();
| | ^ (vrt_count:1 vcl_line:55 vcl_pos:1 src_name:input)

[/code]

show backend status.

show backend status.
past status is window 4times.

[code=’plain’]
backend status
————————————————————

name | status | past status
default | healthy | YY
[/code]

Add run option.

-f [vcl file]

if you set, you can mapping from vcl_trace to vcl source.

this function is unstable.
if you want use this function.
it need change value and set option(–src=on -f=[vclfile] -e=[varnishd]).

before
[code=’php’]
define(‘experimental’ , false);
[/code]

define(‘experimental’ , true);
[/code]

output
[code=’plain’]

varnishlogTrans

Do you use a Varnish? I’ve been using.
I think to using varnishlog for VCL debugging.

For example, the output of the varnishlog that include ESI request.
