qsexec man page

qsexec — parses the data received via stdin and executes the defined command on a pattern match.

Synopsis

qsexec -e <pattern> [-t <number>:<sec>] [-c <pattern> [<command string>]] [-p] [-u <user>] <command string>

Description

qsexec reads log lines from stdin and searches for the defined pattern. It executes the defined command string on pattern match.

Options

-e <pattern>
Specifes the search pattern causing an event which shall trigger the command.
-t <number>:<sec>
Defines the number of pattern match within the the defined number of seconds in order to trigger the command execution. By default, every pattern match causes a command execution.
-c <pattern> [<command string>]
Pattern which clears the event counter. Executes optionally a command if an event command has been executed before.
-p
Writes data also to stdout (for piped logging).
-u <name>
Become another user, e.g. www-data.
<command string>
Defines the event command string where $0-$9 are substituted by the submatches of the regular expression.

Example

Executes the deny.sh script providing the IP address of the client causing a mod_qos(031) messages whenever the log message appears 10 times within at most one minute:
ErrorLog "|qsexec -e \'mod_qos\(031\).*, c=([0-9a-zA-Z:.]*)\' -t 10:60 \'/bin/deny.sh $1\'"
