For more Is my calculation process correct? The following examples show how to do so. See the Prometheus examples of scrape configs for a Kubernetes cluster. One effect of this is that if you're using time-based retention that if a block contains samples that are still inside the time range, then the entire block will be kept around until it is all outside of the retention window. Then run the following command in order to install the prometheus-benchmark for samples or cardinality, ingress traffic is also free. previously recorded, User has hit the active series per metric limit, User has hit the total number of active series limit, Samples are sent out of order and cannot be processed, Label value is longer than allowed character limit.

Besides all the features provided by VictoriaMetrics itself, the service also provides easy-to-configure-and-run Amazon Managed Service for Prometheus vends usage metrics to CloudWatch. AWS uses Cortex project under the hood, so expectations of the disk space used are about 1-2 bytes per sample. 1 Answer Sorted by: 6 Prometheus exposes the metric prometheus_tsdb_head_samples_appended_total in the /metrics path of your prometheus instance. Configuring Prometheus to monitor itself It also has a discount for sparse metrics (histograms) with empty buckets, which they promise chart. Given the per-block ratios between bytes and samples, your sample ingestion rate, your retention period, an extra 10% to allow for blocks that are straddling the retention period, plus another 10% for temporary space during compaction you can calculate your block storage needs with: If you're using size-based retention, then you can reverse the above formula to estimate how much retention time you'll have. This is exactly what managed solutions provide reducing the operational burden and complexity Azure monitor metrics addon collects number of Prometheus metrics by default. Minimal ingestion profile is a setting that helps reduce ingestion volume of metrics, as only metrics used by default dashboards, default recording rules & default alerts are collected.
