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 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=([0-9.]*)' -t 10:60 '/bin/deny.sh $1'" SEE ALSO
