Release Date: February 10, 2021

v1.5.1

Release Date: November 18, 2020

  • Replication factor defaulted to 2.
    • This will double previous storage requirements, as metrics going forward will be replicated across nodes.
    • Metrics stored prior to this upgrade will continue to exist, but only on a single node. This will result in inconsistent query results for non-replicated metrics, depending on which node gets queried.
  • Include and use route registration health check.
  • The replication factor is configurable from OpsManager
  • The max concurrent queries is configurable from OpsManager
  • Updated tile internal certs to include missing SANs. These certs are regenerated automatically

v1.4.5

  • Use Ops Manager as the CA for all certificates to facilitate easier certificate rotation on Metric Store nodes.

v1.4.4

Release Date: September 29, 2020

  • Fixed bug where Metric Store was intermittently dropping points between nodes
  • Added instance_id label to http_* metrics
  • Removed empty errand metric-store-smoke-tests

v1.4.3

Release Date: August 17, 2020

  • This release fixes a memory leak that would cause the Metric Store to slowly run out of memory due to not cleaning up closed network connection go routines.
  • Updated debug and metrics endpoints to be on different ports.
  • Updated Golang to 1.13.12 and Prometheus to 2.19.1.

Known Issues

  • Found in 1.4.2, some customers are experience points being dropped when metrics are transferred between nodes.

v1.4.2

Release Date: April 28, 2020

  • Resolves issue with http_total metric to include correct node_index label value.

Known Issues

  • Found in 1.4.2, some customers are experience points being dropped when metrics are transferred between nodes.

v1.4.1

Release Date: April 27, 2020

  • Updated the opsmanager_syslog property to true to allow operators to egress logs to a syslog destination.

Known Issues

This release has a bug in the http_total metric when the Metric Store is running on multiple nodes. Metric Store incorrectly tracks a label node_index value as 0 as opposed to the true node index. Resolved release 1.4.2.

v1.4.0

Release Date: March 31, 2020

  • Replication is now Availability Zone aware. Note for those upgrading from Beta versions this will cause a loss in metrics.
  • Updated our CA properties to help customers rotate both their Ops Manager and CredHub stored certificates.
  • Updated read sample limit to 20,000,000, previously set to 1,000,000.
  • Removed PromScraper to inject Metric Store metrics into Firehose.
    • Scraping Metric Store Prometheus endpoint via mTLS.

Known Issues

This release has a bug in the http_total metric when the Metric Store is running on multiple nodes. Metric Store incorrectly tracks a label node_index value as 0 as opposed to the true node index. Resolved release 1.4.2.

v0.3.0 (Beta)

Release Date: November 19, 2019

  • Introduced http_total metrics and http_duration_seconds_* histogram for request latency.
  • Fixed metric_storage_duration_days to report 0 when there is no data.
