Cannot install elasticsearch-head plugin

I'm working my way through The Logstash Book and am just at the bit where I install my very first plugin. When I try to run it I get the following error though:

C:\logstash-2.3.2\bin>logstash-plugin install mobz/elasticsearch-head
io/console not supported; tty will not be manipulated
Validating mobz/elasticsearch-head
Plugin mobz/elasticsearch-head does not exist
ERROR: Installation aborted, verification failed for mobz/elasticsearch-head

I'm using an Azure Windows 10 VM.

Any suggestions?

Cheers

Dave

Got it! This is an ElasticSearch plugin, not a Logstash one. Also, on windows, the exe is currently still called plugin.
