The Scylla Enterprise team is pleased to announce the release of Scylla Manager 1.3, a production-ready release of Scylla Manager for Scylla Enterprise customers.
Scylla Manager 1.3 adds a new Health Check, which works as follows.. Scylla nodes are already reporting on their status through “nodetool status” and via Scylla Monitoring Stack dashboards; but in some cases, it is not enough. A node might report an Up-Normal (UN) status, while in fact, it is slow or not responding to CQL requests. This might be a result of an internal problem in the node, or an external issue (for example, a blocked CQL port somewhere between the application and the Scylla node).
Scylla Manager’s new Health Check functionality helps identify such issues as soon as possible, playing a similar role to an application querying the CQL interface from outside the Scylla cluster.
Scylla Manager 1.3 automatically adds a new task to each a new managed cluster. This task is a health check which sends a CQL OPTION command to each Scylla node and measures the response time. If there is a response faster than 250ms the node is considered to be ‘up’. If there is no response or the response takes longer than 250 ms, the node is considered to be ‘down’. The results are available using the “sctool status” command.
Scylla Manager 1.3 Architecture, including the Monitoring Stack, and the new CQL base Health Check interface to Scylla nodes.
If you have enabled the Scylla Monitoring stack, Monitoring stack 2.0 Manager dashboard includes the same cluster status report. A new Alert was defined in Prometheus Alert Manager, to report when a Scylla node health check fails and the node is considered ‘down’.
Example of Manager 1.3 Dashboard, including an active repair running, and Health Check reports of all nodes responding to CQL.
