Hi,
I am trying to order events of wireshark data i.e. events like
time1 src, dst,src_port,dst_port SYN
time2 src, dst,src_port,dst_port FIN
time3 src, dst,src_port,dst_port SYN
time4 src, dst,src_port,dst_port FIN
but transaction creates a transaction out of the time2 and time event. which do not belong together despite using startwith and endwith.
I used the following
eval sdspdp=src+":"+dst+":"+src_port+":"+dst_port
| transaction sdspdp startswith="SYN" endswith="FIN" keepevicted=true unifyends=true | where closed_txn=1 | table time packet_info closed_txn
And I would expect the SYN before the HELLO and FIN, but it isn't. Why ?
time packet_info closed_txn

Thank you Markus |
sample:
index=_internal | head 10 | streamstats count | eval _raw=count, flag="A"
| transaction flag
before transaction, try | reverse
