5. Logging Overview
The Oracle Cloud Infrastructure Logging service is a highly scalable and fully managed
single pane of glass for all the logs in your tenancy. Logging provides access to logs
from Oracle Cloud Infrastructure resources. These logs include critical diagnostic
information that describes how resources are performing and being accessed.

6. How Logging Works
Use Logging to enable, manage, and search logs. The three kinds of logs are the following:
Audit logs: Logs related to events emitted by the Oracle Cloud Infrastructure Audit service. These logs are
available from the Logging Audit page, or are searchable on the Search page alongside the rest of your logs
.
Service logs: Emitted by OCI native services, such as API Gateway, Events, Functions, Load Balancing, Object
Storage, and VCN Flow Logs. Each of these supported services has pre-defined logging categories that you
can enable or disable on your respective resources.
Custom logs: Logs that contain diagnostic information from custom applications, other cloud providers, or
an on-premise environment. Custom logs can be ingested through the API, or by configuring the Unified
Monitoring Agent. You can configure an OCI Compute instance/resource to directly upload Custom Logs
through the Unified Monitoring Agent. Custom logs are supported in both a virtual machine and bare metal
scenario.

9. Types of Logs
Audit logs: Logs related to events emitted by the Oracle Cloud Infrastructure Audit service. These
logs are available from the Logging Audit page, or are searchable on the Search page alongside the
rest of your logs
.
Service logs: Emitted by OCI native services, such as API Gateway, Events, Functions, Load Balancing,
Object Storage, and VCN Flow Logs. Each of these supported services has pre-defined logging
categories that you can enable or disable on your respective resources.
Custom logs: Logs that contain diagnostic information from custom applications, other cloud
providers, or an on-premise environment. Custom logs can be ingested through the API, or by
configuring the Unified Monitoring Agent. You can configure an OCI Compute instance/resource to
directly upload Custom Logs through the Unified Monitoring Agent. Custom logs are supported in
both a virtual machine and bare metal scenario.

10. Getting Started
A log is a first-class Oracle Cloud Infrastructure resource that stores and captures log events
collected in a given context. For example, if you enable Flow Logs on a subnet, it has its own
dedicated log. Each log has an OCID and is stored in a log group. A log group is a collection of
logs stored in a compartment. Logs and log groups are searchable, actionable, and
transportable.
To get started, enable a log for a resource. Services provide log categories for the different
types of logs available for resources.
