UnknownHostException while installing license plugin windows


(Dhiral Kaniya) #1

Hi Team,

I have installed ELK stack on windows server 2016 with metricbeats.
Now I want to install watcher for configuring some alert on a specific scenario.

I have gone through with watcher link. I came to know that i need to install license and watcher plugin so i download license-2.4.6.zip and watcher-2.4.6.zip from this link.

I tried to execute a command to install the elastic-search plugin as below.
bin\elasticsearch-plugin install file://C:/Dhiral/license-2.4.6.zip

Here, I didn't get success to install plugin successfully instead I got some unknownHostException.

Error Trace :-
C:\Dhiral\elasticsearch-6.5.1\elasticsearch-6.5.1>bin\elasticsearch-plugin insta

Can anyone help in that or suggest right way to install this two plugin(s).

Is there a reason you are using such an old version? 6.5.2 is the latest, 2.X is no longer supported.

I assume the this from where I download is latest release of license zip to me. if not then would you please provide resource link where I can download the latest release of License and watcher.?

If you install 6.5.1 then it's all bundled in.

I installed elasticsearch-6.5.1 but I didn't get any license.x-x-x.zip or watcher.x-x-x.zip.
Downloaded elastic-search link :- elastic-search downloaded link
I checked the following folders and i didn't get any license.x.x.x.zip or watcher.x.x.x.zip.

As I mentioned, they are bundled in there automatically, so you don't need to install them.

Hi @warkolm

I was following some old documentation for configuring email, alert and watcher in elasticsearch.
Thanks for your quick replies.
