Header, 19 Bytes

Event size is: header[19] + XID[8] + CRC32[4] of (header + xid)

• Event Time ee b7 15 5a => 5a 15 b7 ee => 1511372782 [2017-11-22 18:46:22]

• Event Type = 10

• Server_id 01 00 00 00 => 1

• Event Size 1f 00 00 00 => 31

• Next Pos f2 0b 00 00 => 00 00 0b f2 => 3058

• Flags 00 00 = 0

Content, 8 Bytes

• XID 66 00 00 00 00 00 00 00 => 102

CRC32, 4 Bytes

• 09 30 45 a8 => a8 45 30 09 => 2823106569
