Uptime Schedule Settings

26 January 2023 · Read time 4 min

Overview

The Uptime Schedule settings are provided for non-critical servers that do not need to be running continuously. For non-running servers, Altinity.Cloud does not bill you for compute resources or support.

• Note that this cost-saving does not apply to storage and backups.

Available uptime schedules covered in this section include:

• ALWAYS ON - CPU always active
• STOP WHEN INACTIVE - CPU shuts off after set hours of inactivity
• ON SCHEDULE - Days of the week, set To and From times down to the minute

The Schedule (clock) icon indicates if a schedule has been set, and serves as a shortcut to quickly open the Uptime Schedule settings window. Other locations include:

• On the Altinity Cluster Manager cluster view, beside each cluster name (See Figure 1 item (A)
• Within the CONFIGURE > Uptime Schedule menu (See Figure 1 item (B)
• On the Dashboard tab of the cluster detail page.

WARNING: Do not use schedules on production clusters that must operate continuously.
