Configure Alerting on Runtime Fabric
Runtime Fabric on VMs / Bare Metal enables you to send alerts through an existing SMTP server. Runtime Fabric on VMs / Bare Metal provides alert functionality to send notifications when system health is compromised.
Install rtfctl
The rtfctl
utility is required to manage alert sender email on Runtime Fabric. Perform the steps in Install rtfctl before completing the following steps.
Procedure
-
Using a terminal, open a shell/SSH connection to a controller VM.
-
Create a file named
alert-smtp.yaml
that contains the following: -
Modify the contents of
alert-smtp.yaml
using the following values specific to your environment:Table 1. Environment Variables Key Description <smtp host>
The endpoint of the SMTP server.
<smtp port>
The port used to connect to the SMTP server. (465 by default).
<username>
The username to use when connecting to the SMTP server.
<password>
The password to use when connecting to the SMTP server.

-
Run the following on the controller VM.

-
Use the
