Tailwatch Log Analysis Tool

(currently chkservdReport.sh)

cPanel’s Tailwatch produces a strange log with details about service checks, formatted in an almost unreadable manner.
My goal for this project is to have a tool that can parse through the log and produce a human-readable report of when services went down, how long they were down for, what it took to get them running again, and so forth.

Usage:

Usage: ./chkservdReport.sh -f<filename> [<additional arguments>]
If you wish to pass the arguments in any order, you must omit the space after the flag letter.
(e.g. -fchkservd.log -m500M -n100000)
By default, -n is set to 10000 (this will go back several days).
Required arguments
-f    filename of chkservd logfile
Optional arguments
-n    number of lines to read from the end of the file (default 10000, pass 0 for unlimited)
-m    manually set the memory_limit - be careful with this! ( e.g. -m128M )
Verbosity and visual options (these are optional arguments)
-vt    Show timeline event explanations
-vp    Show when we reach each step in script execution.
-vc    Colorize output regardless of whether it is entering a pipe to a file/second program or not.

Example of timeline event explanations:

To Do:

• Add timeline entry for large gaps between log entries (e.g. if chkservd is disabled or something)
• Check/test with new chkservd format to see if things are still working properly
