What's New in Prometheus 2.13.0

Prometheus 2.13.0 is now available (2019.10.04), with some fixes and improvements since 2.12.0 last month.

The changes in this version are relatively minor. The tsdb tool is already included in this release, but note that it will most likely be included in promtool in 2.14.0.

Prometheus_sd_configs_failed_total of type counter has been replaced by prometheus_sd_failed_configs of type gauge.

Remote read and write performance has improved. The improvements in remote reading are primarily aimed at users using Thanos, as they allow extraction of entire blocks rather than one sample at a time. Remote Write also provides some new metrics for its queue manager.

The Expression Browser will now display the warnings it receives from the Query API. Promtool indicator linting has some new warnings and improved error messages for bad rules.

There is a security update that fixes a vulnerability in Stored DOM XSS with history queries, CVE number CVE-2019-10215.

For Kubernetes, a new node address type has been added for service discovery.

Detailed release notes can be found in release notes.
