Good afternoon.

How to add java exception in notification message to alert? Currently we using slack as platform for alerts..

i've tried to add this:

- Message3: {{error.exception.message}} {{error.exception.type
}}

{{context.reason}}

{{rule.name}} is active with the following conditions:

- Service name: {{context.serviceName}}
- Environment: {{context.environment}}
- Error count: {{context.triggerValue}} errors over the last {{context.interval}}
- Threshold: {{context.threshold}}

- Message3: {{error.exception.message}} {{error.exception.type
}}

[View alert details]({{context.alertDetailsUrl}})
