Hi Team,
I don't remember changing anything at all on my logstash server. As of just
yesterday it was working fine! And I used it to run some queries.
However.. today when I went to my logstash page, I see only thing message
come up:
Please find the details output below:

When open Kibana web interface it give me below error
Connection Failed
Possibility #1: Your elasticsearch server is down or unreachable
This can be caused by a network outage, or a failure of the Elasticsearch
process. If you have recently run a query that required a terms facet to be
executed it is possible the process has run out of memory and stopped. Be
sure to check your Elasticsearch logs for any sign of memory pressure.
Possibility #2: You are running Elasticsearch 1.4 or higher
Elasticsearch 1.4 ships with a security setting that prevents Kibana from
connecting. You will need to set the following in your elasticsearch.yml:
http.cors.enabled: true
http.cors.allow-origin to the correct protocol, hostname, and port (if not
80) that your access Kibana from. Note that if you are running Kibana in a
sub-url, you should exclude the sub-url path and only include the protocol,
hostname and port. For example, http://mycompany.com:8080, not
http://mycompany.com:8080/kibana.
