How to extract and create a new field from my sample event?

Hi,

Need some help with Field extraction in the following event:

[{\"email\":\"admin@yourstore.com\",\"smtp-id\":\"\",\"timestamp\":1453954498,\"sv_event_id\":\"SDFJGH543534\",\"sv_message_id\":\"filter1.15rasrsar7\",\"reason\":\"test\",\"event\":\"Delivered\"}]

I want the create a new field - EventType for the value of "event:"

While trying to use the Field Extractor, I tried to mark up:

Delivered
"Delivered\"

and etc... but it's not working right.

Thanks !

If you're event is being parsed a JSON, which normally happens automatically, then you can simply use a fieldalias instead of doing a field extraction.

On second glance, is your JSON data escaped? Or is that just a side effect of posting it here? Pretty sure Splunk doesn't handle escaped JSON automatically. So you could either unescape the data on ingestion, possibly using SEDCMD in props.conf, or if that's not an option, try a field extraction with a regex like this:

"event\\":\\"(?<EventType>[^"\\]+)\\"

That event seems to be in Json format and therefore spath is your friend:

| stats count
| eval myjson = "[{\"email\":\"admin@yourstore.com\",\"smtp-id\":\"\",\"timestamp\":1453954498,\"sv_event_id\":\"SDFJGH543534\",\"sv_message_id\":\"filter1.15rasrsar7\",\"reason\":\"test\",\"event\":\"Delivered\"}]"
| spath input=myjson
| rename "{}.event" as EventType
| table EventType

You can ignore the extra escaping for the double quotes and the first two lines that I needed to test this locally on my machine.

Hope that helps.
