Terry,
thank you for your help. I used the type "HTTP Retriever" where it is possible to create points by choosing the groups of the matched regular expression (now I understand the functionallity ;-)). I had to change the expression a little bit. Here is the working implementation as example for others and documentation.
Regular Expression
.*"tuples": \[ \[ ([0-9]+), ([0-9]+\.[0-9]+).\] \] \} \] \}
Target string:
{ "version": "0.5.1", "generator": "vzlogger", "data": [ { "uuid": "123", "last": 1470924327196, "interval": 5, "protocol": "d0", "tuples": [ [ 1470924327195, 115.185 ] ] } ] }
Matcher
group(0) { "version": "0.5.1", "generator": "vzlogger", "data": [ { "uuid": "123", "last": 1470924327196, "interval": 5, "protocol": "d0", "tuples": [ [ 1470924327195, 115.185 ] ] } ] }
group(1) 1470924327195
group(2) 115.185
Configuration in Mango for choosing the value group 2 (115.185)
