Pushover

If you want to change the default notification sound for all notifications then you can add the following in Pushover Options:

sound=falling

You also have the possibility to change sound per severity: sound_critical=falling sound_warning=siren sound_ok=magic

Enabling Pushover support is fairly easy, there are only two required parameters.

Firstly you need to create a new Application (called LibreNMS, for example) in your account on the Pushover website (https://pushover.net/apps).

Now copy your API Key and obtain your User Key from the newly created Application and setup the transport.
