Querying a Date Field in Kibana

Thu, 19 Jan 2017 02:18:24 +0000

When you want to search for data within a certain period in Kibana, the first thing that comes to mind is the built-in Time Picker. It is really handy. But in some cases your data may have more than one date field, and you have to filter with a query instead of the Time Picker. For example, with email data: sending, opening, and clicking each send a log to my server. That gives you two times, one for when the email was sent and one for when the event happened (such as opening or clicking). In a case like this, you may need to search on a date field in the search box.

WTF Elastic X-Pack License - How to uninstall X-Pack

Mon, 16 Jan 2017 10:30:47 +0000

If you found this article through a search engine, you probably feel the same resentment toward X-Pack that I do. At first I thought X-Pack was a free, handy plugin, so I installed it on both Elasticsearch and Kibana. Then 30 days later a message appeared saying the license had expired and I needed to “renew the license key,” otherwise I couldn’t log into Kibana. Up to that point I still assumed I just needed to register an account to get a new license key. But after browsing the official site for a long time, I couldn’t find any text about licensing, pricing, or purchasing (later I found out it does exist — in tiny print… do you people even want to make money?). In the end I only found the pricing page through a Google search.

Setting Up User Authentication for Elasticsearch and Kibana

After you install Elasticsearch and Kibana, you will quickly run into a serious problem: “Wait, where are the username and password?” That’s right, Elasticsearch and Kibana don’t come with the usual user management module. You can only restrict access by binding them to an internal IP or port. But if you’re like my company and don’t have a fixed IP, or you want to set up several accounts, keep reading. This post shares how to set up basic user authentication for Elasticsearch and Kibana using HTTP Auth.
