Prometheus sensor releases

Instana monitors Prometheus endpoints by using the Prometheus sensor. The sensor captures the metrics from these endpoints. For more information, see Prometheus.

1.0.95

Instana Prometheus sensor 1.0.95 is released on 24 April 2025.

Improvements

The delta counters are now refreshed on every parse instead of every 10 minutes. This change improves the memory consumption and avoids a race condition where the counters are cleared during a reset.

1.0.93

Instana Prometheus sensor 1.0.93 is released on 23 April 2025.

Improvements

This release improves the reporting of delta counters. Previously, the sensor constantly reported delta counters, resulting in a high volume of data being sent to the backend. Now, the sensor only reports delta counters with a value greater than 0.

1.0.92

Instana Prometheus sensor 1.0.92 is released on 20 March 2025.

Improvements

This release improves the reporting of delta counters. Delta counters are now reported consistently, whether their values have changed or not, ensuring that values are not incorrectly filled with the previous value.

Fixes

This release adds a minimum sensor API dependency version requirement for new changes that are related to delta counters.

1.0.90

Instana Prometheus sensor 1.0.90 is released on 28 February 2025.

Fixes

This release provides the following fixes:

Discovery of HTTPS Prometheus endpoint when Linkerd service meshes and sidecar patterns are used.
Correct display of HTTPS endpoint URL in the Instana UI. Previously, it was always displayed as HTTP, regardless of the actual scheme.

1.0.89

Instana Prometheus sensor 1.0.89 is released on 17 February 2025.

Fixes

This release fixes a bug that might cause an incomplete histogram metric collection when the metric limit is reached.

1.0.89

Instana Prometheus sensor 1.0.89 is released on 17 February 2025.

Fixes

This release fixes a bug that might cause an incomplete histogram metric collection when the metric limit is reached.

1.0.88

Instana Prometheus sensor 1.0.88 is released on 5 February 2025.

Fixes

This release logs Prometheus sensor labels with identical or similar values when in DEBUG mode.

1.0.87

Instana Prometheus sensor 1.0.87 is released on 5 February 2025.

Fixes

This release adds minor fixes and optimizations to the parsing of Prometheus payloads.

1.0.86

Instana Prometheus 1.0.86 is released on 12 December 2024.

Fixes

This release fixes a bug in the discovery of prometheus endpoints in pods with prometheus.io/scrape: true and prometheus.io/port annotations, which are used whenever the prometheusAnnotation: strict field is set in the sensor configuration.

1.0.84

Instana Prometheus 1.0.84 is released on 10 December 2024.

Features

This release introduces new delta counters to enhance Prometheus metrics. For more information, see Prometheus.
