Scripts
-
freespace.pl -- Easy parser for df -h. Usage:
perl freespace.pl --filesys="/dev/sda1" --option="Size" > output
where each filesys is a drive and each option is a column on the df -h table (Filesystem, Size, Used, Avail, Capacity, Mounted on).
-
tops-scrubber.pl -- Easy parser for top. Usage:
perl top-scrubber.pl --type="mem" --detail="free" > output
where the type is info (line 1), tasks, cpu, mem, swap, and the detail for each line depends on the parameters parsed out. Here are some more examples.
# 1, 5, 10-min load avg -- first row of top
perl top-scrubber.pl --type="info" --detail="load_1"
perl top-scrubber.pl --type="info" --detail="load_5"
perl top-scrubber.pl --type="info" --detail="load_10"
# idle and iowait -- cpu row of top
perl top-scrubber.pl --type="cpu" --detail="id"
perl top-scrubber.pl --type="cpu" --detail="wa"
# swap - buffers, free.
perl top-scrubber.pl --type="swap" --detail="buffers"
perl top-scrubber.pl --type="swap" --detail="free"
# tasks -- running, zombie
perl top-scrubber.pl --type="tasks" --detail="running"
perl top-scrubber.pl --type="tasks" --detail="zombie"
Use the debug statement to get a snapshot of all values, and to see supported type flags (left col) and detail flags (indented in []'s):
perl top-scrubber.pl --debug
- process_report.pl -- counts and averages on open processes.
Usage:
# Reports the average cpu usage from any open processes with httpd in its command
perl process_report.pl --process="httpd" --metric="cpu" --summary="avg"
# Counts how many CGI processes are open
perl process_report.pl --process="cgi" --metric="count"
# Reports max cpu usage of all the open foo.cgi processes
perl process_report.pl --process="foo.cgi" --metric="cpu" --summary="max"
You can report summary= avg, max, min across metrics=cpu, mem, time (where time is the number of seconds the process has been running).
