I did openNMS mail configuration and Slack integration for Event Notification.
Notifications are sending to e-mail and Slack channel, but i don't want all notification alert [ warning , critical , normal, minor, Major ].
I need only critical and normal alert notification.
Is this possible to send critical, normal alert notification only to Slack channel and E-mail.
if it's possible can you tell me that, how to configure.
