Log data inefficient

[s33butler]

Is it possible to not pad the logs or remove the padding before ingest or writing to data? It makes the logs 3 times the size of normal firewall logs cause a very large increase to the license requirements on SIEMs such as Splunk.

There is really no need for 9 x "N/A"'s or 9 x "unknown" and definitely no need for 310 x "0 Zeros"
