#syslog-benchmark
Syslog benchmark utility written in Go
##Background At $DAYJOB, I was tasked with building an über rsyslog cluster to collect all logs from everything. In order to make sure a single node in this cluster could handle a massive syslog load, I needed to build a tool that could simulate sufficient syslog traffic.
##Usage Specify as many (or as few) flags as you'd like. Hit ctrl+c (or whatever your OS interrupt is) to stop sending messages.
Upon receiving an interrupt, syslog-benchmark will stop sending messages and perform some basic post processing.
###Flags
-host="localhost": hostname of syslog server
-msgs=100: number of messages to send, -1 = unlimited
-port=514: port of syslog server
-proto="tcp": protocol of syslog server: tcp/udp
-tag="syslog-benchmark": syslog message tag
##Examples All defaults (100 messages, port 514, tcp, 'syslog-benchmark' tag)
