Script to monitor an LEB uptime (like pingdom but not)
I have a few of LEBs (like most here probably 
) and I was wondering if anyone knows of a script I can set up to ping/monitor HTTP from one back to another. Not bothered about RAM/CPU usage just if it's reachable. I want to put it on my 3 LEBs and have them watch each other and email me if they go down.
I was going to put together a small python app to do it but if it already exists why bother

A quick Google search revealed this, though of course you'll be reliant on another box being up to monitor it:

Are you serious? Just scroll down the front page a little and see the thread about OpenStatus, or use the search function and see the 284082740892704827048742089724 other threads about this.
I've always thought of it through 1 VPS with excellent uptime monitoring all my VPS. But "monitoring each other" is a very good idea I believe. And OpenStatus is indeed a great work you can follow the link http://www.lowendtalk.com/discussion/781/openstatus-0.4.0-released
I do monitoring from a local Linux box. Of course it fails if my Internet connection is down, but in that case I'm not going to fix anything anyway
I have 1 box doing my status page and another which monitors everything via ping. Both will email me if one is down.
Used this sometime back when I had few boxes. You'll have to run one for each box you want to monitor.
Only advantage is, you can choose to ignore predetermined number of subsequent ping failures before sending a mail alert. (You will have many single ping failures on most of the boxes and it will be a real headache if you get a mail for each.)
It also notifies back when box is online.
#!/bin/bash #usage : bash pingh.sh hostname_or_ip interval=60 #scan interval in seconds fcount=0 ignoref=2 #attempts to ignore alerted=0 while true; do ping -c 1 $1 &>> plog.txt if [ $? -ne 0 ]; then let "fcount+=1" if [ "$fcount" -gt "$ignoref" ] && [ $alerted -eq 0 ]; then echo "`date`: $1 down!" | mail -s "$1 down" [email protected] alerted=1 fcount=0 fi else if [ $alerted -ne 0 ]; then echo "`date`: $1 online!" | mail -s "$1 online" [email protected] alerted=0 fcount=0 fi fi sleep $interval doneConfigure to run it in the background at system startup. If you don't want a log of the ping data, replace plog.txt with /dev/null
You can't brag about it when it's local though like many folks like to do with it.
why not use NickM's monitor script?
Sorry I posted on the wrong post.
