Elastic Stack Logstash
1

I used Logstash to send alert email when application exception via smtp with ssl.But Logstash reported ':exception=>#<OpenSSL::SSL::SSLError: Received fatal alert: handshake_failure' When deliver mail.What Happened? At first it works well.
The version of logstash: 2.3.4；
OS Version:CentOS 7.
Here is Log:
{:timestamp=>"2016-07-31T23:13:06.864000+0800",
:message=>"Something happen while delivering an email",
:exception=>#<OpenSSL::SSL::SSLError: Received fatal alert: handshake_failure>,
:level=>:error}
Plugin:Logstash-output-email

Providing your config would be useful.

Thanks, Mark.
We have solved this problem.
The email provider stopped our email function. log-stash can't communicate to email server via ssl protocol.
