Hi all,
i am using logstash from more than 2 years. i have recently observed that same configuration of logstash is not working on some of my servers.
troubleshooting:
I have started logstash in debug mode, and found that logstash is receiving and processing data properly but i am unable to view that data on graylog UI. while the same config data that i have configured on other servers, i am able to view that content on UI.
Kindly suggest what would be wrong.
