SYNOPSIS

DESCRIPTION

11     The varnishhist utility reads varnishd(1) shared memory logs and presents
12     a continuously updated histogram showing the distribution of the last N
13     requests by their processing.  The value of N and the vertical scale are
14     displayed in the top left corner.  The horizontal scale is logarithmic.
15     Hits are marked with a pipe character ("|"), and misses are marked with a
16     hash character ("#").
17
18     The following options are available:
19
20     -b          Include log entries which result from communication with a
21                 backend server.  If neither -b nor -c is specified,
22                 varnishhist acts as if they both were.
23
24     -C          Ignore case when matching regular expressions.
25
26     -c          Include log entries which result from communication with a
27                 client.  If neither -b nor -c is specified, varnishhist acts
28                 as if they both were.
29
30     -d          Process old log entries on startup.  Normally, varnishhist
31                 will only process entries which are written to the log after
32                 it starts.
33
34     -I regex    Include log entries which match the specified regular expres‐
35                 sion.  If neither -I nor -i is specified, all log entries are
36                 included.
37
38     -i tag      Include log entries with the specified tag.  If neither -I
39                 nor -i is specified, all log entries are included.
40
41     -n          Specifies the name of the varnishd instance to get logs from.
42                 If -n is not specified, the host name is used.
43
44     -r file     Read log entries from file instead of shared memory.
45
46     -V          Display the version number and exit.
47
48     -w delay    Wait at least delay seconds between each update.  The default
49                 is 1.  file instead of displaying them.  The file will be
50                 overwritten unless the -a option was specified.
51
52     -X regex    Exclude log entries which match the specified regular expres‐
53                 sion.
54
55     -x tag      Exclude log entries with the specified tag.
