# Plugin by Greg Connor
#
# 1. Drop or symlink "mhttping" into plugins dir
#
# 2. Edit mhttping to tell it where the "data" text file and "results"
# writable directory are.
#
# 3. Create the file "data" with a list of things to do...
#
# Format must include name= url= proxy= in that order (spaces or tabs ok)
# Use proxy=none for direct
#
# name=google_mtv1 url=http://www.google.com
# proxy=proxy1.mydomain.com:8080
# name=yahoo_mtv1 url=http://www.yahoo.com proxy=proxy1.mydomain.com:8080
# name=www_direct url=http://www.mydomain.com proxy=none
#
# 4. Add to crontab to make "mhttping run" execute every 5 minutes, offset
# from munin time a bit. This can be any user who can run "httping" and
# write to the "results" dir.
#
# 2-59/5 * * * * /home/gconnor/mhttping/mhttping run >
# /home/gconnor/mhttping/log 2>&1
#
# 5. Verify that "mhttping run" works, from command line and from cron. Then
# verify that "mtthping config" and "mhttping fetch" work.
#
# 6. Restart munin-node.
