Hi all, i am using nxlog to convert log from cef to json, output the same : {"SourceModuleName":"udp","timestamp":"2020-07-30T10:23:53.433042+07:00","serverity":"Low","signature":"/Execute/Query","category":"/Success","action":"keyinst","direction":"0","host":"192.168.51.15"} i want to add fields "vendor_id":"xxxx","unit_id":"00000","sensor_id":"xxxx" to before message and change the order of fields. After message the same: {"vendor_id":"xxxx","unit_id":"00000","sensor_id","timestamp":"2020-07-30T10:23:53.433042+07:00","action":"keyinst","direction":"0","host":"192.168.51.15""SourceModuleName":"udp","serverity":"Low","signature":"/Execute/Query","category":"/Success",} Thanks!
