# Logging DevOps customers can easily review log data, diagnose issues, and use the rules engine to trigger serverless Functions or alerts with Oracle Cloud Infrastructure (OCI) Logging. Built on open standards, OCI Logging is an intuitive, centralized platform for all types of logs, such as audit, infrastructure, database and applications, which are needed for DevOps and security compliance. For interoperability, OCI Logging uses the Cloud Native Computing Foundation (CNCF) fluentd agent for log ingestion and the CNCF CloudEvents standard for log events. Pricing for Logging is based only on storage and includes a generous free tier. Log ingest and search are free.

Easily collect logs including application, auditd, syslog, and Windows event logs from OCI, on-premises hosts, and other cloud providers. ##### Secure sensitive log data Use log groups to limit access to your most sensitive logs. Log groups can restrict access and audit every interaction with these logs. #### Search and analyze logs ##### Intuitive log search language Logging provides a new, intuitive SQL-like query language for easy log analysis of all log types—infrastructure, application, audit, and database. ##### Log aggregation and filtering Easily diagnose and correlate issues across the entire stack. Aggregate and filter data from all applications, infrastructure, audits, and databases. ##### Visualize log data and trends Seamlessly chart and visualize data from all services and applications in one view. #### Robust integrations ##### Take action with the rules engine The rules engine allows users to take action on logs, such as triggering custom code or sending an alert. Using [Connector Hub](/content/apac/devops/connector-hub/index.html), Logging can be integrated with [Monitoring](/content/apac/cloud/systems-management/monitoring/index.html), [Notifications](/content/apac/cloud/systems-management/notifications/index.html), and [Streaming](/content/apac/big-data/streaming/index.html). ##### Integrate with third-party providers Export logs to Object Storage or leverage Kafka-compatible [Streaming](/content/apac/big-data/streaming/index.html) for easy integration with third-party SIEM providers including Splunk. Logging also supports Grafana dashboards. ##### Emit log-based metrics Emit metrics directly from logs into [Monitoring](/content/apac/cloud/systems-management/monitoring/index.html), enabling features, such as alarms and [Notifications](/content/apac/cloud/systems-management/notifications/index.html). With log-based metrics, DevOps engineers can use a single view for infrastructure and applications. ##### Archive your logs for indefinite retention Archive logs for auditing and compliance into [Object Storage](/content/apac/cloud/storage/object-storage.html) buckets that can be retained indefinitely or automatically purged through lifecycle policies. #### Open-standards-based ##### Fluentd support Logging leverages Fluentd to easily deploy, configure, and manage agents. Developers can use hundreds of open source community plugins to ingest, parse, and enrich their logs. ##### CloudEvents for interoperability with the cloud native ecosystem Every event ingested into Logging is automatically normalized into the CloudEvents 1.0 format for easy interoperability with other cloud native tools. ##### Kafka-compatible Streaming Data and DevOps engineers can use existing Kafka connect integrations to push logs to Kafka-compatible streams. ## Customer and partner successes for Logging Organizations can manage their log data with Logging’s native capabilities as well as its interoperability with the cloud native ecosystem and Grafana. ## Logging use cases - ### Ingest flow logs from Virtual Cloud Networks (VCNs) Logging supports ingestion from VCNs as well as other OCI resources, such as Functions and API Gateway. - ### Ingest logs from applications and hosts Easily deploy and manage agents across an entire fleet of hosts directly from the console. Ingest and parse the logs directly using Fluentd. - ### Secure access to sensitive log data Limit access to sensitive logs to only specific users within log groups, or integrate with [Identity and Access Management](/content/apac/security/identity-management/index.html) to define access policies and rules. Any unauthorized request will be denied and audited for security. - ### Search and analyze all logs in a single view Filter, aggregate, and visualize all logs in one view—infrastructure, application, audit, and database. - ### Integrate with the ecosystem Push logs to third-party observability tools, such as Splunk, using Connector Hub. ### Resources #### Documentation - [Getting started](https://docs.cloud.oracle.com/en-us/iaas/Content/Logging/Concepts/loggingoverview.htm) - [All documentation](https://docs.cloud.oracle.com/en-us/iaas/Content/home.htm) #### Training - [Online training and certification](https://mylearn.oracle.com/ou/story/35644/)
