Applicable to ENA v18.0 upwards
In ENA, you can specify a maintenance period for a device. This means that you can take a device down for maintenance, but ENA does not report its non-responsiveness as an outage (and therefore no event is raised).
This is useful, for example, if you have clients who have SLAs and you need to see 100% uptime in reports (e.g. user defined availabilty for network devices, firewalls and IP telephony devices) that takes into consideration scheduled maintenance downtime.
The features of maintenance mode are as follows:
- when maintenance mode is set for a device, data is still collected.
- when a report is generated, the maintenance section of time is ignored.
- set and finish maintenance mode manually, or schedule it to start and finish at specific times and at repeating times.
- view, create, edit and delete maintenance schedules via the ENA UI or RESTful API.
