Hi All,

I'm facing some issues with the large hexadecimal values in the Keywords
field of im_msvistalog input module. A typical value from a real system is
0x8080000000000000 which exceeds the upper limit of Long data type in Java
[and gets overflowed]. Moreover, any intermediate tools/scripts/parsers
using formats like JSON simply throw an exception.

It says in NXLOG documentation that this field is an Integer [1] and makes
a reference to 'EvtSystemKeywords'. EvtSystemKeywords says it's a
'EvtVarTypeHexInt64' type [2].

I'm very new to NXLOG so am wondering if there's a way I can force this
field to be a String. Else considering dropping it altogether at Logstash.


Thanks,
new23d
