This section lists monitoring and maintenance activities recommended to ensure high availability and consistent performance of your HAWQ cluster.
The tables in the following sections suggest activities that a HAWQ System Administrator can perform periodically to ensure that all components of the system are operating optimally. Monitoring activities help you to detect and diagnose problems early. Maintenance activities help you to keep the system up-to-date and avoid deteriorating performance, for example, from bloated system tables or diminishing free disk space.
It is not necessary to implement all of these suggestions in every cluster; use the frequency and severity recommendations as a guide to implement measures according to your service requirements.
