External downtime alerting#
Stakater App Agility Platform provides downtime notifications for Applications via IngressMonitorController which out of the box integrates with UptimeRobot and many other services. For this guide we will configure a Slack channel for receiving the alerts; but you can configure any medium supported by the service (email, PagerDuty, etc.).
To configure downtime alerting do following:
- Configure incoming webhook in Slack
- Create alert contact on UptimeRobot with webhook
- Update IMC configuration
- Enable EndpointMonitor in the application
- Validate downtime notification
1. Configuring incoming webhook in Slack#
- While in your Slack workspace, left-click the name of your workspace, and pick
Administration
>Manage Apps
from the dropdown Menu. - A new browser window should appear in which you can customize your workspace. From here, navigate to
Custom Integrations
and then toIncoming WebHooks
. - Now you can configure a new
Incoming WebHook
by clicking the big, greenAdd Configuration button
. - The first form lets you pick any existing channel or user on your workspace to notify when the WebHook is called. A new channel can also be created here.
- After picking a channel or user to be notified, click the
Add Incoming WebHooks Integration
Button. The most important part on the next screen is theWebHook URL
. Make sure you copy this URL and send it to Stakater Support - Near the bottom of this page, you may further customize the Incoming WebHook you just created. Give it a name, description and perhaps a custom icon.
