Hello friends,
Is this possible to write a Logstash plugin for fetching data in Javascript just as we can do with Java ?

No it is not, you can write a Logstash plugin in [ruby](https://www.elastic.co/guide/en/logstash/current/contributing-to-logstash.html) or [java](https://www.elastic.co/guide/en/logstash/current/contributing-java-plugin.html).

Hi @leandrojmp, Thanks for your response
I want to fetch some metrics data from the Vrops(VMware) api that includes following steps -
1. Make a post request to get the authentication token with login credentials
2. Use that authentication token with a GET request to get the the metrics data of various VMs
Is this possible to achieve with Logstash, and If yes than how can I achieve this ?

It is not possible, the logstash has a [http\_poller](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-http_poller.html#plugins-inputs-http_poller) plugin, but this plugin needs to be configured with the authentication token, it cannot make a request to get the authentication token.

How about to use Filebeat/EA and ingestion?

Also, there is a [workaround](https://discuss.elastic.co/t/http-poller-rest-api-authentication-token/246870/5). Might be useful.
