By using offset, the value is always integer because it just calculates the difference between start and end.

Do you prefer darker user interfaces, especially when using Prometheus at night? In pull request 8604, Łukasz Mierzwanow added the ability to switch the web UI from its default light version to a dark mode: It's also possible to tell Prometheus to use the browser-preferred theme (using the right-most black/white button in the video). The dark UI mo...
Normally, recording rules in Prometheus only start recording results starting from the time at which they are added to Prometheus. There has been a long-standing issue to allow evaluating rules retroactively on old data, so that Prometheus users can access rule results directly for those older time ranges. As a first step to address this, Jessica G...
To achieve high availability for monitoring, it's common to run multiple Prometheus servers with identical configuration. However, as an exception to their identical configuration, you often want to be able to assign different external_labels to each Prometheus server, to differentiate replicas (e.g. replica: prometheus-a and replica: prometheus-b)...
Prometheus normally requires pre-allocating 512MiB of disk space for new TSDB chunk segment files. This can make it hard to use Prometheus in small environments, where the actual data to be stored in each chunk segment is only a few MiB and the available disk space is low. To make Prometheus work better for those use cases, Nathan Berkley added a f...
In an ongoing effort to make Prometheus work better in more environments, the new release furthermore adds two new service discovery mechanisms: Robert Jacob added support for discovering Docker engine containers as scrape targets in pull request 8629. You can check out the Prometheus documentationfor all configuration details. A contributor going ...
When talking to other systems (scrape targets, Alertmanager, remote-write endpoints, and so on), Prometheus already supported multiple authentication schemes: bearer tokens, basic authentication, TLS client certificates, and more (depending on the situation). In addition to those, in pull request 8761 Levi Harrisonnow added support for configuring ...
In our blog post about Prometheus 2.26, we already mentioned the importance of trace exemplars and how Prometheus 2.26 added support for storing them in memory and retrieving them via an HTTP API. This required setting the --enable-feature=exemplar-storageflag. In Prometheus 2.27, Callum Styan now went one step further and added support for sending...
A lot has happened in Prometheus 2.27 to make it work better for more use cases and to integrate it more with other systems. Go try it out now!
Apr 1, 2021 · Regarding the application layer: With Prometheus, it is common that developers will generate RED metrics using the Prometheus client libraries to get a better understanding of application state and performance — and be able to slice that data by metadata fields (URL, host, data center, and so on) — for much faster problem detection versus troubleshooting via logging alone.
Apr 1, 2021 · For Prometheus 2.26, we worked to bring this new editor functionality to Prometheus itself and hope that this will greatly improve people's PromQL experience: The new editor is still experimental for this release, so you have to turn it on explicitly by enabling the "Use experimental editor" checkbox. In later releases, we expect it to become ...
