| **Data Ingestion Rate** | Per Tier Limits | Number of [time series](https://docs.victoriametrics.com/keyconcepts/#time-series) ingested per second. |
| **Active Time Series Count** | Per Tier Limits | Number of [active time series](https://docs.victoriametrics.com/faq/#what-is-an-active-time-series) that received at least one data point in the last hour. |
| **Read Rate** | Per Tier Limits | Number of datapoints retrieved from the database per second. |
| **New Series Over 24 Hours** (churn rate) | `<= Active Time Series Count` | Number of new series created in 24 hours. High [churn rate](https://docs.victoriametrics.com/faq/#what-is-high-churn-rate) leads to higher resource consumption. |
| **Concurrent Requests per Token** | `<= 600` | Maximum concurrent requests per access token. It is recommended to create separate tokens for different clients and environments. This can be adjusted via [support](mailto:support@victoriametrics.com). |
For a detailed explanation of each parameter, visit the guide on [Understanding Your Setup Size](https://docs.victoriametrics.com/guides/understand-your-setup-size.html).
| **Max Label Value Length** | `<= 1kb` (Default: `4kb`) | Maximum length of label values. Longer values are truncated. Large label values can lead to high RAM consumption. This can be adjusted via [support](mailto:support@victoriametrics.com). |
| **Max Labels per Time Series** | `<= 30` | Maximum number of labels per time series. Excess labels are dropped. Higher values can increase [cardinality](https://docs.victoriametrics.com/keyconcepts/#cardinality) and resource usage. This can be configured in [deployment settings](https://docs.victoriametrics.com/victoriametrics-cloud/quickstart/#modifying-an-existing-deployment). |
