New in ScyllaDB Monitoring Stack 3.7

• Overview dashboard enhancements:
  • Add manager task progress indication to the overview dashboard #1250
    The Manager progress is now part of the header rows, for example, this is how a backup looks like:

• Hinted handoffs being accumulated/being sent – annotation #1258
  When a node is temporarily down, the updates that would have been sent to it are stored as hints, when the node is up again, those hints are sent. This translates to extra load on other nodes. There are optional annotations for storing and sending hints.

• Secondary Indexes/Materialized Views background-built – annotation #1257
  When adding a Secondary Index or a Materialized View to an existing table, the new index will be built in the background. This will add extra load on the nodes. You can use the MV annotation to see when a Materialized View or Secondary index is being built.
• Provide an indication of coordinator / replica errors per node #1229
  Visually present error/no error on the node table #1035

The Node Table, found on the DC section that is part of the overview dashboard, can indicate when there are CQL optimization warnings, and when there are errors on the node.

• CQL Dashboard
  • Add CQL errors to dashboards #1276

ScyllaDB 4.4 comes with additional  CQL errors. The new CQL Errors panel, found on the CQL dashboard, will show those errors. Please note, that for clarity, only active errors will be shown.

• • Add more info to client table (ScyllaDB Open Source 4.4) #1259ScyllaDB Open Source 4.4 adds additional information to the client table found on the CQL dashboard.
• Update ScyllaDB Manager Dashboard #1180
  The manager dashboard got a facelift. It now shows the last success and last failure of Backup and Repair tasks.

• Panel for ScyllaDB HWLB #907
  Heat Weighted Load Balancing (HWLB) is an optimization mechanism that distributes queries according to the probability a requested value will be in the cache.
