New in Scylla Monitoring Stack 3.4

Dashboards for Scylla 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.

Scylla 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.

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 Scylla 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
