Configuring email account for Watcher breaks Elasticsearch

Elastic Stack Elasticsearch
1

Hi there! I recently upgraded my ELK setup where Logstash and Elasticsearch are at 2.0.0 and Kibana at 4.2.0.
So I wanted to install Watcher 2.0.0 so I could try out the new features.

I wanted to try the email function just to check if watcher was working properly.

I "sudo nano /etc/elasticsearch/elasticsearch.yml" the yml of elasticsearch and entered this at the bottom of the file:

watcher.actions.email.service.account:
  work:
    profile: gmail
    email_defaults:
      from: myemail@gmail.com
    smtp:
      auth: true
      starttls.enable: true
      host: smtp.gmail.com
      port: 587
      user: myemail@gmail.com
      password: mypassword

Obviously the email and password changed for privacy reasons.
When I save this edit and restart elasticsearch it gives me a red start with the text "elasticsearch is not running"
Before the edit and restart it gave me a white star with "elasticsearch is running".

So what gives? Just to put it out there, I uncommented the network.host and port for connection reasons but that did not stop elasticsearch from running before I added the email configuration.

Thanks :smile:

If Elasticsearch doesn't start I'm sure there will be something in the logs about it.

Ah thanks @magnusbaeck ! Well here is a noob question but I'm currently using a bash terminal in Windows to manage my ELK setup. I haven't got much experience in either so I'm at kind of a loss as how to grab the logs. Can you guide me in the right direction so I can take a gander at the logs?

Elasticsearch usually stores its logs in /var/log/elasticsearch.

@magnusbaeck

Took me a while (laptop broke down) but I managed to get to my logs using another computer and a connection to the server.

I can't see anything out of the ordinary to be honest. maybe you see something of interest?

I've exactly the same problem.

Sadly I have yet to find out why. I moved on to other project as this was just an experiment
