I'd like to run external commands from Mango, like ping, du, ps, etc. How to do that to use them as data source,
like vmstat? I'd like to check if systems are reacheable, slow, or up and running nicely, like Nagios active checks.
How to run external commands
Use can use the event handler to run a script on the server but this won't return any value to Mango. If you wanted to have a data source that would ping an IP address it would just have to be created. I'll look into this and let you know what I think. If it's something you wanted to do and you have he skills it would probably be one of the easier data sources to create.
