We have no idea that Some one restarted tomcat server where filebeat is running. Filebeat dead since then.
So almost 10 days later we observed that filebat on that server not pushing logs, as a result we lost so much data(logs).
Sometimes Elasticsearch ran into issues, went down. We won't get alerts until some one say that kibana is not showing anything.
So, can someone please help me that
- How can i monitor ELK stack along with beats.(My company won't give budget for x-pack ).
- We need alerts, when any of the above services went down. So it can capable to send email?
Thanks in advance.
