The ScyllaDB team is pleased to announce the release of ScyllaDB Monitoring Stack 4.4.0 [ScyllaDB Monitoring Stack](https://monitoring.docs.scylladb.com/) is an open-source stack for monitoring [ScyllaDB Enterprise](https://www.scylladb.com/product/scylla-enterprise/) and [ScyllaDB Open Source](https://github.com/scylladb/scylla), based on Prometheus and Grafana. ScyllaDB Monitoring Stack 4.4.0 supports: - ScyllaDB Open Source versions 5.0, 5.1 and 5.2 - ScyllaDB Enterprise versions 2020.x, 2021.x and 2022.x, 2023.1 - ScyllaDB Manager 3.0.x, 3.1.x This release focuses on adaptation for ScyllaDB Open Source 5.2 and the upcoming ScyllaDB Enterprise 2023.1 metrics changes and reduced load from Prometheus servers for large clusters. It is advised to upgrade the monitoring stack before upgrading ScyllaDB.

The new filter would allow users to explicitly choose which scheduling groups are shown. [image] - Remove internal scheduling\_group\_name from p99 [#1939](https://github.com/scylladb/scylla-monitoring/issues/1939) Internal SERVICE LEVEL (e.g. scheduling groups) are used for internal tasks, like compaction, are typically set to run at lower priority not to interfere with user activity. They are now removed from the p99 report as they do not represent real traffic. - Disk size panel update [#1958](https://github.com/scylladb/scylla-monitoring/issues/1958) The disk size panel was updated to make it clearer what is the used part out of the entire available disk. [image] - Update the alerts table [#1930](https://github.com/scylladb/scylla-monitoring/issues/1930) Following the changes in Grafana integrated Alerts, ScyllaDB Monitoring now uses Grafana’s Alert table for clearer representation. [image] - Update the Advisor section [#1953](https://github.com/scylladb/scylla-monitoring/pull/1953) The advisor section was updated to match Grafana’s alerts system. It is now completely alert based. Detailed Dashboard Changes - Added panels for CQL request and response sizes [#1928](https://github.com/scylladb/scylla-monitoring/issues/1928) There is a new section under the per-scheduling group section for payload size. It reflects the network usage for different kinds of CQL messages. There are also estimation panels for read and write, they give a ballpark estimate of an average read/write message. The section helps identify issues that result from large messages. [image] Advanced Dashboard - Show scylla\_io\_queue\_starvation\_time\_sec metrics [#1915](https://github.com/scylladb/scylla-monitoring/issues/1915) [image] Scylla-Manager Dashboard Changes - Add progress of the restore process enhancement [#1960](https://github.com/scylladb/scylla-monitoring/issues/1960) [Scylla Manager 3.1](https://forum.scylladb.com/t/release-scylla-manager-3-1-release/524) supports a new restore from backup implementation, which exposes how much data remains to complete restore, in bytes. A new panel in the Manager dashboard graphs this data. [image] General Changes - Added missing descriptions to panels [#1966](https://github.com/scylladb/scylla-monitoring/pull/1966) As part of an effort to make the dashboard clearer, a description (a popup with an explanation) was added to the panels where it was missing. Bug Fixes - Empty alert manager rules when using consul [#1951](https://github.com/scylladb/scylla-monitoring/issues/1951) - The links in the advisor balance section are broken [#1949](https://github.com/scylladb/scylla-monitoring/issues/1949) - Fix legend of IO-Queue panels [#1916](https://github.com/scylladb/scylla-monitoring/issues/1916) Operational Changes - Prepare for Scylla open source 5.2 summaries [#1972](https://github.com/scylladb/scylla-monitoring/pull/1972) - Add a command line option to drop cas/cdc metrics [#1948](https://github.com/scylladb/scylla-monitoring/issues/1948) - Reduce the number of collected histograms: do not collect “internal” scheduling groups’ latency histograms [#1971](https://github.com/scylladb/scylla-monitoring/issues/1971) - Datadog - do not report per-shard metrics [#1944](https://github.com/scylladb/scylla-monitoring/pull/1944) - Change alert levels to text [#1927](https://github.com/scylladb/scylla-monitoring/issues/1927)
