Solution Architecture and Components

This architecture diagram shows the components involved in logging.

In the "Siebel CRM Observability – Log Analytics" solution, the primary log collection and aggregation tasks are done by the agents of application Fluentd.

Fluentd is a Cloud Native Computing Foundation (CNCF) graduated open source log data handler. Fluentd helps unify all facets of processing log data: collecting, filtering, buffering, and streaming across multiple sources and destinations. It has a flexible plugin system that allows the users to extend its functionality with minimal development efforts. Fluentd does not need significant physical resources to function and can be easily setup for high availability. It is one of the leading log collection and aggregation engines in the cloud native ecosystem.

For collecting logs from pods running Siebel Server deployment components like AI, Server, Gateway and so on, Fluentd log-collector agents are deployed as sidecars.

In addition, all nodes contain a Fluentd log collector running as a Kubernetes DaemonSet to collect logs that are not specifically covered by the sidecar Fluentd agents.

Logs collected by collector agents are passed onto the log aggregation agents of Fluentd. These, in turn, pass on the necessary data to the Logging Analytics components like Oracle OpenSearch and OCI Log Analytics – which have Dashboards and other UI components available to view, query, and analyze logging and other data available in the logging analytics layer.
