Planned maintenance (maintenance windows)

3 min read · Status pages

A maintenance window is a pre-announced time slot during which your service is expected to be temporarily out of operation. During this time ePulz.io will not send any downtime alert and an information banner will appear on your public status page. Visitors can see that you are aware of everything and have it all under control.

How to schedule maintenance

In the monitor detail, open the Maintenance window section and fill in the following:

Start and end of the window in the DD.MM.YYYY HH:MM format, in your account time zone.
A short description - what exactly is being done, what impact it will have and who it affects.

Each maintenance window applies to a single monitor. For a deployment that takes down both the website and the API at the same time, create a separate window for each monitor.

Monitor detail in ePulz.io where a maintenance window is scheduled — You schedule the maintenance window right in the monitor detail, next to its history and availability metrics

What happens during the window

The status page shows a yellow information banner with the time and description of the maintenance.
The monitor switches to the Maintenance state (yellow color).
No alerts are sent via e-mail, Telegram or webhook, even if the monitor returns an error.
Checks keep running and the results are recorded in history for your information.
After the window ends, the monitor automatically returns to normal mode.

What does not count as downtime

During a maintenance window ePulz.io does not escalate the state to DOWN, does not store an incident and does not send any alert, even if the monitor returns an error. Planned maintenance therefore does not show up as an unplanned outage.

Checks still run during the window and their results are recorded in history - you have a transparent trail of when and why the service was out of normal operation.

Tips from practice

Schedule at least 24 hours in advance - both customers and colleagues have time to arrange their things.
Be specific in the description: what you are doing, how long it will take, who it affects and to what extent.
Choose times with the lowest traffic (early morning, late evening, weekend).
If the maintenance finishes early, you can end the window manually - the banner hides immediately.
If, on the other hand, the maintenance runs long, extend the window before it ends so you do not start getting false alerts.
