logcheck-test [-q|-i] [-a|-s|-l FILE] -r RULEFILE

Description

logcheck-test parses a log file for matching lines specified by a single rule or a rule file. If using a single RULE you can set a PREFIX and a SUFFIX to write new rules easily.

Options

-h, --help
Show usage information
-a, --auth.log
Parse /var/log/auth.log for matching lines
-s, --syslog
Parse /var/log/syslog for matching lines
-l, --log-file FILE
Parse FILE for matching lines
-i, --invert-match
Show line that don't match the RULE or the RULEFILE
-q, --quiet
Suppress rule summary at the end of output
-e, --surround-rule

Surround RULE with standard prefix and suffix:

^[[:alpha:]]{3} [ :[:digit:]]{11} [._[:alnum:]-]+ RULE$

-P, --append-prefix PREFIX
Append PREFIX to rule prefix. Option can be given multiple times
-S, --prepend-suffix SUFFIX
Prepend SUFFIX to rule suffix. Option can be given multiple times
-r, --rule-file RULEFILE
Use file RULEFILE for rule input

Examples

With logcheck-test you can easily write and test new rules.

Test a single rule against /var/log/syslog:

logcheck-test -s "RULE"

Test a single rule against ~/log, surround the rule with standard prefix and suffix and append "kernel " to prefix:

logcheck-test -l ~/log -e -P "kernel " "RULE"

Test the rules in rulefiles/linux/ignore.d.server/kernel against ~/log:

logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel

Test which lines the rules in rulefiles/linux/ignore.d.server/kernel doesn't match:

logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel -i

Exit Status

On successful matching logcheck-test will complete with exit code 0. An exit code of 1 indicates no successful matching.

An exit code greater then 1 indicates an error occurred. Textual errors are written to the standard error stream.
