I installed x-pack (both in Elasticsearch and Kibana, and also restarted all services) and tried to set an email alert by using watcher. However, when I clicked "test fire email", it gave me error showing " Watcher: Cannot read property 'message' of null" and then the browser forced me to quit the page and had to re-login. Couple weird things happened when I have been doing the watcher email alert configuration:
- Every time when I installed x-pack ( I have tried install ELK in both CentOS and Ubuntu), the Kibana would just stop to receive any information from metricbeats and showed "no result found " page.
- The last time I set this alert configuration, it showed me different error, which was "MessagingException: can't determine local email address"
Does anyone have any idea what is the problem? Thanks!
