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
VG

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](http://output.So) my concern is if nothing is running then what is this output.

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.
