Hi Experts,

Sorry to ask a very basic question , How I can check the logstash speed . I mean how many lines events/logs per second it is parsing or reading ?

Thanks

WOW!! it helps Navneet, but I have a quick question . Since my prod LS thread is already running , so do I need to create another thread for metrics LS filter.

What I observe even if I stopped all LS , it still giving me the output.So my concern is if nothing is running then what is this output.

today I use statsD

Hi Jeferson,

Can you please guide me how you use it in LS config file ?

I use the StatsD output:

			statsd
			{
				namespace => "logstash"
                                    increment => ["1"]
				host => "host"
				port => port
			}

after that, you have to use the elasticsearch statsd plugin to send this to ES or use Graphite
the StatsD will generate how many events pass in Logstash.
