varnishhist [-b] [-C] [-c] [-d] [-I regex] [-i tag] [-n varnish_name] [-r file] [-V] [-w delay] [-X regex] [-x tag]
The varnishhist utility reads varnishd(1) shared memory logs and presents a continuously updated histogram show‐ ing the distribution of the last N requests by their processing. The value of N and the vertical scale are dis‐ played in the top left corner. The horizontal scale is logarithmic. Hits are marked with a pipe character (“|”), and misses are marked with a hash character (“#”).
The following options are available:
| -b | Include log entries which result from communication with a backend server. If neither -b nor -c is specified, varnishhist acts as if they both were. |
| -C | Ignore case when matching regular expressions. |
| -c | Include log entries which result from communication with a client. If neither -b nor -c is specified, varnishhist acts as if they both were. |
| -d | Process old log entries on startup. Normally, varnishhist will only process entries which are written to the log after it starts. |
| -I regex | Include log entries which match the specified regular expression. If neither -I nor -i is specified, all log entries are included. |
| -i tag | Include log entries with the specified tag. If neither -I nor -i is specified, all log entries are included. |
| -n | Specifies the name of the varnishd instance to get logs from. If -n is not specified, the host name is used. |
| -r file | Read log entries from file instead of shared memory. |
| -V | Display the version number and exit. |
| -w delay | Wait at least delay seconds between each update. The default is 1. file instead of displaying them. The file will be overwritten unless the -a option was specified. |
| -X regex | Exclude log entries which match the specified regular expression. |
| -x tag | Exclude log entries with the specified tag. |
The varnishhist utility was developed by Poul-Henning Kamp in cooperation with Verdens Gang AS and Linpro AS. This manual page was written by Dag-Erling Smørgrav.
