varnishncsa [-a] [-b] [-C] [-c] [-D] [-d] [-f] [-I regex] [-i tag] [-n varnish_name] [-P file] [-r file] [-V] [-w file] [-X regex] [-x tag]
The varnishncsa utility reads varnishd(1) shared memory logs and presents them in the Apache / NCSA “combined” log format.
The following options are available:
| -a | When writing to a file, append to it rather than overwrite it. |
| -b | Include log entries which result from communication with a backend server. If neither -b nor -c is specified, varnishncsa 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, varnishncsa acts as if they both were. |
| -D | Daemonize. |
| -d | Process old log entries on startup. Normally, varnishncsa will only process entries which are written to the log after it starts. |
| -f | Prefer the X-Forwarded-For HTTP header over client.ip in the log output. |
| -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. |
| -P file | Write the process’s PID to the specified file. |
| -r file | Read log entries from file instead of shared memory. |
| -V | Display the version number and exit. |
| -w file | Write log entries to file instead of displaying them. The file will be overwritten unless the -a option was specified. If varnishncsa receives a SIGHUP while writing to a file, it will reopen the file, allowing the old one to be rotated away. |
| -X regex | Exclude log entries which match the specified regular expression. |
| -x tag | Exclude log entries with the specified tag. |
The varnishncsa 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 ⟨des@des.no⟩.
