Need Help monitoring a web device

[Harris]

Hello,

I'm trying to figure out wich would be the best way of monitoring an Websensor EM01B.

This is a very simple device that only answer to ping and to http requests (where you can get the information about the sensors).

Here's an example:

http://xxx.xxx.xxx.xxx/index.html?em

Outputs:
rM701668TC: 21.7HU:35.2%IL: 32.4
(temperature, humidity and illumination)


This is what i where planing:

On zabbix server machine, i would create a shell script running on cron
with the follow content:

#!/bin/bash
SENDER="/usr/local/sbin/zabbix_sender -z 127.0.0.1 -p 10051"

wget http://xxx.xxx.xxx.xxx/index.html?em --output-document=websensor.tmp -q

TC=`cat websensor.tmp |grep body |cut -f 2 -d : |cut -f 1 -d H`
HU=`cat websensor.tmp |grep body |cut -f 3 -d : |cut -f 1 -d %`
IL=`cat websensor.tmp |grep body |cut -f 4 -d : |cut -f 2 -d ' '`

# Only for debug purposes
echo $TC
echo $HU
echo $IL

$SENDER -k ?????? -o $TC
$SENDER -k ?????? -o $HU
$SENDER -k ?????? -o $IL

Now i'm facing 2 problems:
1) no idea of what to insert on the -k option
2) no idea of how to create the items for this host on zabbix

Btw, is this the correct way of monitoring this kind of device?

Thanks in advance

1) -k is for the item's key.
2) Make an item with type Zabbix trapper.

Try the sender command manually, and you'll see if it fails.

I think this method is fine.

Ok, but this is my main question, when i'm creating an item of type zabbix trapper, it asks for the key, the pre-built ones are for zabbix agent, internal, aggregated or simple check, i believe that none of those satisfy what i need, so i think that i need to insert a custom value there, but i dont know what i have to insert.

Thanks!

You can use whatever you like. It just has to be unique.

Thanks Niels, it worked very well!
