The varnishncsa utility reads varnishd(1) shared memory logs and
26
presents them in the Apache / NCSA "combined" log format.
28
The following options are available:
30
-a When writing to a file, append to it rather than overwrite it.
32
-b Include log entries which result from communication with a
33
backend server. If neither -b nor -c is
34
specified, varnishncsa acts as if they both were.
36
-C Ignore case when matching regular expressions.
38
-c Include log entries which result from communication
39
with a client. If neither -b nor -c is specified,
40
varnishncsa acts as if they both were.
44
-d Process old log entries on startup. Normally, varnishncsa
45
will only process entries which are written to the log
48
-f Prefer the X-Forwarded-For HTTP header over client.ip in
51
-I regex Include log entries which match the specified regular
52
expression. If neither -I nor -i is specified,
53
all log entries are included.
55
-i tag Include log entries with the specified tag. If neither -I nor
56
-i is specified, all log entries are included.
58
-n Specifies the name of the varnishd instance to get logs
59
from. If -n is not specified, the host name is used.
61
-P file Write the process's PID to the specified file.
63
-r file Read log entries from file instead of shared memory.
65
-V Display the version number and exit.
67
-w file Write log entries to file instead of displaying them.
68
The file will be overwritten unless the -a
71
If varnishncsa receives a SIGHUP while writing to a file,
72
it will reopen the file, allowing the old one to be
75
-X regex Exclude log entries which match the specified
78
-x tag Exclude log entries with the specified tag.
