Release details​


new
Prometheus API for SLO time series​

The Prometheus API for SLO time series is now available, exposing Nobl9 SLO data through a Prometheus-compatible API.

Use PromQL to query reliability, remaining error budget, burn rate, good and total counts, raw SLI values, and composite SLO component metrics.

Use it when you want to analyze SLO health outside the Nobl9 app: build Grafana dashboards, compare SLOs across projects with PromQL, pull SLO time series into scripts, or feed SLO values into internal reporting workflows.

For example, you can find objectives in a project with less than 20% error budget remaining:

budget{project="my-project"} < 0.2

To get started, see the Prometheus API guide and the Prometheus API reference.

Start with the PromQL examples to explore common SLO questions, then connect Grafana or your preferred Prometheus client when you are ready to automate the workflow.

new
Dynatrace DQL support​

Dynatrace DQL query support is now available in the SLO Wizard for the Dynatrace direct data source.

You can author an SLO metric with either the existing Metric selector or a DQL query.

new
Generate ad-hoc Reliability Roll-up report API​

You can now generate Reliability Roll-up report data from a Report manifest without creating a saved report.

Use this endpoint in CI or custom tooling to validate Reliability Roll-up definitions and preview report output before promoting a saved report configuration.

new
MCP support for Alert policy analyzer​

The MCP server now supports Alert policy analyzer workflows through tools for calculating alert policy suggestions, starting analyses, fetching results, and retrying failed analyses through the SDK.

It also includes a calculate-alert-policy prompt that helps compare candidate policies for a specific SLO objective and time range and returns analysis URLs for review.

new
MCP support for Prometheus API​

The MCP server now supports Prometheus API for SLOs endpoints for querying SLO metrics data.

improved
Alert policy analyzer policy selector grouping​

The Alert policy analyzer existing-policy selector now groups alert policies linked to the analyzed SLO separately from all other policies. This makes it easier to identify which policy was used to trigger the analyzed alert.

improved
Time window metadata in Alert policy analyzer​

Alert policy analyzer now displays the SLO time window type, so you can see whether the analyzed SLO uses a calendar-aligned or rolling time window.
