To ensure that all your information is logged and stored in a centralized location, I built a full HA cluster of graylog nodes and elasticsearch nodes which I will use to keep track of my application. https://dchua.com/posts/2015-12-25-using-graylog-extractors/ Fri, 25 Dec 2015 00:00:00 +0000 https://dchua.com/posts/2015-12-25-using-graylog-extractors/ If you’re new to Graylog, Graylog Extractors are a great way to pull out information from your logs for easier storing and manipulation. If like me, you sometimes experience a “String fields longer than 32kb” indexing error on one of your fields, a good way to help mitigate it is to use extractors to split your field into two. I wouldn’t recommend this all the time as obviously the way to solve this is to set your particular field to be non_indexable but in certain cases when you need the full data and still want to be able to search for it, this might be the better solution.
