Summarize Apache Extended server-status to show longest running requests

Ever need to know why Apache is bogging down *right now*? Hate scanning Apache's Extended server-status for the longest running requests? Me, too. That's why I use this one liner to quickly find suspect web scripts that might need review.

Assuming the Extended server-status is reachable at the target URL desired, this one-liner parses the output through elinks (rendering the HTML) and shows a list of active requests sorted by longest running request at the bottom of the list. I include the following fields (as noted in the header line):

Seconds: How long the request is alive

PID: Process ID of the request handler

State: State of the request, limited to what I think are the relevant ones (GCRK_.)

IP: Remote Host IP making the request

Domain: Virtual Host target (HTTP/1.1 Host: header). Important for Virtual Hosting servers

TYPE: HTTP verb

URL: requested URL being served.

Putting this in a script that runs when triggered by high load average can be quite revealing. Can also capture "forgotten" scripts being exploited such as "formmail.pl", etc.

What others think

Very nice! Using this almost verbatim, but added CPU util back in..

FWIW, debian links does not like the --dump, just a single - is fine.

hm, getting back: Unknown option http://localhost/server-status but the apache2 module is on:

a2enmod status

Module status already enabled

links -dump 1 http://localhost/server-status|grep ^[0-9]|awk 'BEGIN {print "Seconds, PID, State, IP, Domain, TYPE, URL\n--"} $4 !~ /[GCRK_.]/ {print $6, $2, $4, $11, $12, $13 " " $14|"sort -n"}'

Seconds, PID, State, IP, Domain, TYPE, URL

Unknown option http://localhost/server-status
