Managing Notifications

Rumble can trigger automatic notifications when certain events occur through a combination of Channels and Rules.

Rumble currently supports Internal, Email, and Webhook channel types.

Internal channels store events within the Notifications list within the Rumble Console. Internal notifications support explicit acknowledgement. Internal channels can be bulk acknowledged and cleared from within the Rumble Console.

Email channels can be configured to deliver mail to one or more recipients. These email messages contain a summary of the notification and a link to the specifics within the Rumble Console. Email is sent from the Rumble infrastructure using the Sendgrid service.

Webhook channels allow Rumble to post notifications to internet-reachable web services. The post request contains a standard text message for use with platforms like Slack and Mattermost, but also additional fields containing the full notification details. Webhooks are a great way to tie Rumble notifications into third-party platforms.

To trigger a notification on a channel, a Rule must be created. Rules define which events lead to notification on which channels. The name of the rule will be included in the notification content and should describe the type of event that it monitors.

The following event types can be used to create rules:

  • Scan Completed
  • New Assets Found
  • Assets Back Online
  • Assets Now Offline
  • Assets Changed

Scan Completion and Assets Changed rules can be noisy but may be useful to keep a running log of network changes over time. For a typical monitoring use case, a rule would be created to trigger on Assets Now Offline, Assets Back Online, and New Assets Found, automatically notifying an email alias or a Slack channel.

Notification rules, when combined with recurring scans, can be a simple way to track network changes over time.
