How Thanos Almost Snapped $100,000 from our Infra Budget
11-05, 10:40–11:10 (US/Central), ROOM 1

In a galaxy not so far away, where data is as vast as the cosmos, our team was troubled with observability data chaos.
Seeking some clarity, we sought salvation with Thanos and Fluentbit – fabled titans against our metric storage and logging issues.
Thanos empowered us with a Prometheus setup with high availability and virtually infinite historical data storage. Prometheus ascended to new heights, flawlessly scaling horizontally while Thanos Compactor's downsampling abilities promised faster results for querying older data.
Fluentbit made collecting, filtering, and outputting logs across multiple sources and destinations effortless.

But, little did we know that even the most powerful tools, when not wielded correctly could be double-edged Infinity Stones.

Join us on a thrilling tale of blunders as we recount some missteps in configuring these tools, easily missed caveats in data downsampling and log storage, and how the pursuit of seamless data handling almost cost us over $100,000.


Thanos and Fluentbit are some of the most widely trusted, recommended and deployed projects in the Cloud Native space. These tools are robust 'batteries included' solutions, that have made monitoring, storing and handling logs and metrics much simpler for countless organisations. However, for teams new to observability and the cloud, some of the best practices and suggested configurations may not be easily evident and they'll have to burn their fingers with exponential cloud costs and lost data before these caveats become more apparent.
With this talk, we aim to glance over why Thanos and Fluentbit are the best solutions for modern metric and logging problems, and with our firsthand mistakes as an example, illustrate how some configuration and setup errors within these tools and improper systems to detect these errors can cause astronomically high costs.
