# User and Cluster Administration

The topics in this section provide the following information:
* How to set up SingleStore's native monitoring solution to maintain cluster health, connect external visualization tools to the cluster's monitoring data, and troubleshoot the monitoring setup.
* The comprehensive metrics exposed by SingleStore that help determine the cluster's health and performance, predict resource constraints, and diagnose issues.
* Replication and Durability concepts, configuration, usage, and troubleshooting.
* High Availability architecture, setup, management, and usage with examples. Database replay configuration using logs and snapshots.
* Cluster administration tasks, such as setting redundancy levels, determining license capacity and usage, updating license, controlling memory usage, changing the host IP address in a cluster, taking leaves offline without cluster downtime, and more.
* Cluster scaling, including cluster expansion and downsizing steps.
* Online and offline upgrade of SingleStore and uninstall processes.
* Data migration from MySQL and application transition to SingleStore.
* Troubleshooting of system, node, and query performance issues.
* Setup dedicated admin connections.
* Effective workload management using built-in workload manager and by setting resource limits.
* Overview of SingleStore Tools including Toolbox and client. Tools installation processes and migration from MemSQL Ops to SingleStore Tools.
