Logstash plays an extremely important role in any ELK-based data pipeline but is still considered as one of the main pain points in the stack. Like any piece of software, Logstash has a lot of nooks and crannies that need to be mastered to be able to log with confidence.

More than 1.55 million room nights are reserved on the Booking.com platform every day. It’s a staggering amount of traffic, and not surprisingly, the Amsterdam-based travel e-commerce company has a lot of knowledge to share about handling metrics at scale.

When people talk about web analytics, you immediately think of Google Analytics. But there is life beyond Google Analytics.

Last week, Amazon announced its Open Distribution for Elasticsearch. And MongoDB Inc. abandoned OSI approval of its new SSPL license.

When I was a kid, we would head to the city to buy things, everything from a pair of shoes to new school supplies. As I grew up in the 1990s, we were introduced to a new way of shopping: malls.

The rest of the city may still have been in a post-Oscars haze, but over 350 monitoring mavens gathered in downtown L.A. bright and early on Feb. 25 to kick off GrafanaCon 2019. The next two days were filled with 40+ talks, including Grafana end user stories from companies like Bloomberg and Tinder.
