limiting number of msg types in json

[babuveld]

Is the number of msg types per json payload configurable so we have option to limit the overall json payload size.

[e.g] in below case if I would like to have only one entry in "messages" is that configurable?

{
"sequence":1937,"timestamp":"1543630887.105",
"messages":[
{"type":1300,"data":"arch=c000003e syscall=42 success=yes exit=0 a0=3 a1=245e2e0 a2=10 a3=100007fffff0000 items=0 ppid=12714 pid=14304 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts11 ses=4918 comm="nc" exe="/bin/nc.openbsd" key="netconns_out""},
{"type":1306,"data":"saddr=02000050ACD90AEE0000000000000000"},
{"type":1327,"data":"proctitle=6E6300676F6F676C652E636F6D003830"}],
"uid_map":{"0":"root"}
}
