Hello I monitor some IoT by ping. These are then displayed in green or red on the dashboard if they are alive or not. The more there are the more work and maintenance there is. Is there a way where I read a comma or semicolon separated IP list and query them one by one so that all IPs are shown i…

Question - anyone know if we can determine OS in a flow? I'd make this demo universal if I could.

It might be better to use node-red-node-ping which would presumably cope with such differences.

Colin, if i'm not mistaken, node-red-node-ping node doesn't accept input - OP needs a list to process. I am aware there is another ping node that accepts input but, I wanted to make it operate without additional external nodes to simplify things - plug and play for any user - however, in hindsight.…

I am currently porting ICMP from names as a set of tools for Node-Red , you should be able to listen for pings/messages , i will post an announcement rely soon(probably today) , but there should be some things that will be needed fixing.

[image] Steve-Mcl: anyone know if we can determine OS in a flow Well in node.js - require('os').platform(); is probably the most useful.

Yeah cheers Dave, was aware of that however that would require a user to modify settings.js in node-red world right? Was just wondering if there were a specific env var that we could query on a standard flow that reliably identified the breed (windows/*nix) for this kind of situation? In a Functio…

@Steve-Mcl You uncomment it in settings.js // The following property can be used to seed Global Context with predefined // values. This allows extra node modules to be made available with the // Function node. // For example, // functionGlobalContext: { os:require('os') } …

Yeah, as I suspected - however thats not really quick and "handy" for a demo (asking folks to modify settings.js) Was just curious if an ENV var could identify windows/nix to simplify areas where we might use an EXEC node to do some dirty work and be compatible (as best as possible) with other OSs …

[image] Steve-Mcl: useful for the flow... I would have to disagree - while "useful", I think it only encourages people to write platform specific code which we don't really want in function nodes etc. At least inside a node you can hope that a developer does the right thing and handles the mu…
