New in ScyllaDB Monitoring Stack 3.4

• Dashboards for ScyllaDB Open Source 4.1 #926
• Upgrade to Grafana 6.7.3 from 6.6 #855
• Upgrade to Prometheus 2.18.1 from 2.15.1 #854
• Support range annotations #852
  With the addition of Grafana’s range annotation, the Manager task annotations are now shown as a range.This is how a running repair looks like on the graphs.

• ScyllaDB Manager 2.1 added agent and server system metrics #874
  There is a new Manager agent section in the Manager dashboard that monitors the Manager-Agent that runs on each of the nodes.
  
• Set units “ops, rps, wps to ops/s reads/s and writes/s #737
  Some of the dashboards units were unclear, for example, ops can mean both operations/seconds or operations. Using Grafana user-defined types, it was changed to more precise types.
  
• Add a quick navigation that keeps the time selection #946
  The filtering line has now a quick dashboard navigation that keeps the time range and variable selection.
  
• Scheduling group CPU metrics are now averaged by default #945
  In the CPU dashboard, the usage is now averaged by default with an option to choose another aggregation function.

Operational Changes

• Allow saving of provisioned dashboards from the UI #802
  It is now possible to save changes you made to a dashboard. You should do so with care. If you want to make persistent changes to your dashboard you should use an external directory for Grafana (see ScyllaDB Monitoring documentation).
• node_exporter scrap is set to 1m #919
  node_exporter is an agent that reads the OS related metrics from a node (memory, disk usage and network) reducing its scrap interval, reduces some unneeded load from the nodes and is safer in case of a slow response.
• Update the alertmanager plugin to 0.0.8 #917
  Add Apache Licence to the project #263

Bug Fixes

• Fix relative path for internal links #952
• Filter out ScyllaDB Manager successful health check annotation #941
