NAME
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 or-
der to trigger the command execution. By default, every pattern match causes a com-
mand 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 "|/usr/bin/qsexec -e \'mod_qos\(031\).*, c=([0-9a-zA-Z:.]*)\' -t 10:60
\'/usr/local/bin/deny.sh $1\'"
