Monitor the health and performance using the Health Dashboard that ships automatically with every Levitate cluster.

We are releasing the health dashboard for all Levitate clusters. The health dashboard will help in understanding the performance and state of each Levitate luster. It will give you a complete picture of the Levitate cluster performing in real-time.
Consider it same as status page for each Levitate cluster, but one that you can customize, set alerts on and can take full advantage of!

The health dashboard contains information such as
- How many write requests are succeeding?
- Rate of sample ingestion
- Read and Write availability
- Ingestion lag and latency
- Cardinality limits
- …and many more failure modes.
The complete list can be found here.
