Yandex Managed Service for Prometheus® overview
Yandex Managed Service for Prometheus® is a monitoring system compatible with Prometheus. You can use it to collect, store, and query metrics from your containers, applications, and infrastructure. The system leverages the Prometheus data model and PromQL, enabling you to use your current Grafana dashboards.
Prometheus features multiple tools for collecting metrics, including libraries for widely-used programming languages and support for exporting metrics from external systems, such as databases, message queues, and more. Yandex Managed Service for Prometheus® enables you to use best practices of the Prometheus open-source community, while ensuring high scalability, availability, and security with no need to deploy Prometheus clusters and manage the internal monitoring infrastructure on your own. To get started with Yandex Managed Service for Prometheus®, install agents that support the Remote Write protocol.
Yandex Managed Service for Prometheus® is based on the system Yandex uses to monitor its internal services. The system automatically scales metric write, storage, and read operations depending on the workload. Monitoring data is replicated across two availability zones, ensuring high availability.
Getting started
To start using Yandex Managed Service for Prometheus® in the current folder, you need to create a workspace. To do this:
- Open the Yandex Monitoring home page.
- In the left-hand panel, select Prometheus.
- Click Create workspace.
- On the page that opens, you will see links to the endpoints to use for the current folder.
To enable Prometheus-formatted metric writing and reading, follow the relevant guides.

| Long-term metric storage | Not intended for long-term metric storage, using third-party solutions | Support for long-term metric storage, with time-unlimited storage possible through decimation. |
| Reading metrics | Data and metadata reads via the HTTP API | Data and metadata reads via the HTTP API with some restrictions |
| Visualization | Expression browser, Grafana | Support for Prometheus data source |
| Aggregation | Aggregation via recording rules | Support for existing recording rule files in YAML format, which you can upload and manage via the Monitoring UI and API. |
| Alerting | Alerting via alerting rules | Support for existing alerting rule files in YAML format, which you can upload and manage via the Monitoring UI and API. |

Note
Alerting rules are at the Technical Preview stage. To access the feature, contact support.
Current limitations
- The
NaNvalue is not supported and is treated as a missing point. - The
+Inf/-Infvalues may be processed incorrectly. - Alerting rules only support email and Telegram channels, with no dynamic routing.
staleness markers,exemplars, andnative histogramsare not supported.
Quotas and limits
Yandex Managed Service for Prometheus® has the following limits:
- Quotas are organizational constraints that our support team can change upon request.
