it looks like data is a broken array of one object, part of which is a
further quoted json string.
There should be a string value after the isEvent but I have no idea what
it should be, nor what else should come after.
"message":"tdetails":{att:val pairs}
is also wrong in the first level of inner json.
I think he wants data[0]['message'], but the inner json strings are
broken too, and should look more like.
data: "[{\"Severity\":\"warn\",\"Subject\":\"Reporting\",\"Message\":
\"tdetails\",\"attr_name\":\"{\\\"Product\\\":\\\"Gecko\\\",\\\"CPUs\\
\":8,\\\"Language\\\":\\\"en-GB\\\",\\\"isEvent\\\":\\\"attr_value\\\"}\"}
]",
In this model, if the data attribute is a json string, then
data maps to a list / array
data[0] maps to an object / dictionary
data[0]["Message"] maps to the string literal "tdetails"
data[0]["attr_name"] maps to a string representation of a json ob with
another level of escaping.
That string can then be loaded, eg:
attr_name = json.loads(data[0]["attr_name"])
