Alerting

The Alerting feature notifies the SAP Administrator about important events detected in the Landscape being monitored/observed by Trento.

Some of the notified events:

  • Host Health detected critical
  • Cluster Health detected critical
  • Database Health detected critical
  • SAP System Health detected critical
  • ...

Enabling Alerting

This feature is disabled by default.

Provide ENABLE_ALERTING=true as an environment variable when starting Trento.

Delivery and Recipient

A notification needs to be delivered to someone in some way.

With alerting enabled some extra configuration is needed to define the recipient and the delivery mechanism.

Currently authenticated SMTP is the only supported delivery mechanism for alert notifications.

ENABLE_ALERTING=true
ALERT_SENDER=sender@yourmail.com
ALERT_RECIPIENT=recipient@yourmail.com

SMTP_SERVER=your.smtp-server.com
SMTP_PORT=2525
SMTP_USER=user
SMTP_PASSWORD=password

Enabling Alerting at a later stage

If your current Trento installation has Alerting disabled, you can enable it by upgrading the helm deployment.

helm upgrade
   --install <THE_DEPLOYMENT> 
   --set trento-web.adminUser.password=<ADMIN_PASSWORD>
   --set-file trento-runner.privateKey=<PRIVATE_SSH_KEY>
   --set trento-web.alerting.enabled=true
   --set trento-web.alerting.smtpServer=<SMTP_SERVER> 
   --set trento-web.alerting.smtpPort=<SMTP_PORT>
   --set trento-web.alerting.smtpUser=<SMTP_USER>
   --set trento-web.alerting.smtpPassword=<SMTP_PASSWORD>
   --set trento-web.alerting.sender=<ALERT_SENDER> 
   --set trento-web.alerting.recipient=<ALERT_RECIPIENT>
