Got it working. When trying with .map, I copied the code verbatim again, but my 
"operating" system is Ubuntu, not Debian.

Already fixed in later versions of the documentation: ticket is here:

The line above is wrong - you are using each() and it returns its input.


As said, this comes straight from the documentation.

Did you mean to use map() to get an array of the names? That is, like 
this:


   $debian_nodes = puppetdb_query($debian_nodes_query).map |$value| {
 $value["certname"]

Try output of all first so you see if you got any, then output the 
mapped result.

- henrik


$value["certname"] }
Notify {"Debian nodes":
 message => "Your debian nodes are ${join($debian_nodes, ', ')}",
}
which prints:

Notice: Your debian nodes are {"certname"=>"host1.example.com"}, 
{"certname"=>"host2.example.com"}


despite the '$value["certname"]'. What would I need to do to print the 
names only? Like:


Notice: Your debian nodes are host1.example.com, host2.example.com

which is what I would expect the code above to do in the first place.

Thanks...

Dirk
