Health+ provides ongoing, real-time analysis of performance and configuration
data for your Confluent Platform deployment. From this analysis, Health+ sends out
notifications to alert users to potential environmental issues before they
become critical problems. Also, the Confluent Support team uses the collected
metadata to enhance the support experience with context around the performance
and usage of the deployment to lower the time to resolution for support issues.
Subscribe to notifications
Subscribe to notifications in the Confluent Cloud UI by navigating to the Health+
Overview page and creating a new notification subscription.
You can send notifications to a specified integration, like Slack and email, or
to a generic webhook to integrate with a custom application.
When sending notifications using a webhook to a custom application, expect the
following JSON schema for the webhook payload.
id: string [required]
rule_id: string [required]
severity: string [ENUM: INFO, WARN, CRITICAL, ERROR] [required]
status: string [ENUM: RAISED/CLEAR] [required]
Here’s an example payload:
"title": "ClusterId:WHdCF0FZQLSPRu8vItiAaA - RequestHandler idle alert",
"message": "Cluster with ID WHdCF0FZQLSPRu8vItiAaA\n\nRequestHandlerAvgIdlePercent falls under the range 5.05 and 15.05\n\nCurrent Value = 7.05\n\nAction Recommended:\n\nSuggested Action:\n\nFurther Reading:\n\nDocumentation link\n\nQuestions? Please reach out to Confluent Support and reference this alert",
Confluent adds new Health+ rules on an ongoing basis as new optimizations are
discovered, with no user intervention required. This ensures Confluent Platform deployments
that have enabled Health+ benefit from Confluent expertise continuously.
Health+ rules are evaluated in real time and are intended to alert
users of potential issues within minutes.
Data collection and processing
If enabled for Health+ purposes, Confluent Telemetry Reporter sends
the following types of information back to Confluent.
- Performance statistics internal to each Confluent Platform service
- System utilization statistics
- Cluster IDs
- Topic names
- Host names
- Version information
- Connector types
- ksqlDB application IDs
This level of metadata is necessary to provide the Health+ service
and enable the Confluent Support team to assist with issues efficiently and
effectively. The data flowing through the topics in the Confluent Platform deployment is
You can view a representative set of metrics by consuming from the
_confluent-telemetry-metrics topic in your Confluent Platform deployment.
