[Help] Read values from a web page?

[rumbLe]

Hi, I would like to read values (temperature and humidity) from a Web page to create a graph and some triggers.

Is there anyone who can guide me in the right direction on how to do that?

See if you can create a custom script to parse web page and return required values to zabbix ( check UserParameter in zabbix_server.conf file). Then create a key based on this to get graphs/set triggers.

P.S - For parsing web pages i had used WWW::Mechanize in Perl, not sure if now that module supports parsing web pages with JS/Flash etc.

Thanks.

Hi zabbixfk, thanks for the suggestion.

What I wanted to do was to read values from my home automation system (Fibaro HC2), which has a JSON API.

I achieved this by scheduling a .bat script on my Windows server that:

1. Downloads the "json" page using wget.
2. Fetch the intresting values from the downloaded page using JQ (https://stedolan.github.io/jq/).
3. zabbix_sender to send the data to zabbix.

There are probably easier and better way to handle this using python or VB scripts, but this seems to work.
