Uptime Schedules

Managing your server uptime using Altinity.Cloud schedules

Uptime Schedule Settings

This section covers common settings for each Schedule setting.
Schedule settings are provided for non-critical servers that do not need to be running continuously.
Servers that are not running reduces costs.

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

Available uptime schedules covered in this section include:

  • Always on
  • Stop when inactive
  • On schedule

The Schedule (clock) icon is used in various places:

Uptime Schedule Icon

All users who have access to the cluster dashboard may access uptime

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

Uptime Schedule Access Path

Important note! Uptime schedules are intended for ClickHouse clusters
that only operate intermittently. Do not enable them for production
clusters that operate continuously. Doing so may cause the ClickHouse
server to stop unexpectedly, creating a potential service outage.

Accessing Uptime Schedules

To set up an uptime schedule open the cluster dashboard and select Uptime
Schedule from the CONFIGURE menu. The Clusters View page allows you to
view available clusters and access your profile settings.

Uptime Menu

Clusters with an active uptime schedule will also have a stopwatch icon
beside the cluster name on the dashboard panel. You can access the uptime
schedule by clicking on the icon.

Uptime Schedule Icon

If there is no icon, it means that no uptime schedule is currently active.

Regardless of how you access the uptime schedule, you will see a popup
window that shows the current status. The default setting is ALWAYS ON,
which means the cluster operates continuously.

Default Uptime Schedule

Stopping Servers after a Period of Inactivity

Select STOP WHEN INACTIVE to configure the cluster to stop after a period
of inactivity. For example, you may stop clusters after two hours of
inactivity. This is a useful setting for development servers. Choose
your desired inactivity period. Press CONFIRM to save the setting.

Inactive Uptime Schedule

Once the server becomes inactive, you must restart it manually using
the ACTIONS->RESUME on the cluster dashboard.

Stopping Clusters on a Schedule

You may also configure clusters to run on a schedule using the ON
SCHEDULE tab. The following example shows how to configure a server to
run 24 hours on Monday, Wednesday, Friday and 8am to 5pm on Tuesday,
Thursday. Note that the time zone is GMT, so you’ll need to convert
your local time zone to GMT values. Press CONFIRM to save the schedule.
