OCI Logging
What is OCI Logging?
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.
Using Logging you can manage and search throw all logs from your network without login to any server ( everything from OCI console)
Three Type of logs:
- Audit Logs – Read only logs from the Audit service provided for you to analyze and search
- Service Logs – Logs that are emitted by OCI native services like API Gateway, Events, Functions, Load Balancing, Object Storage, and VCN Flow Logs.
- Custom Logs – diagnosing information from the custom application, on-premise environment, another cloud provider.
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 will have 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.
How To Enable Logging for Server?
In this post we will enable a logging for server logs like syslog and apache. As we will log only from single server this will preset just logic how to enable. Real advantage you will have when you use this to monitor logs from all servers in your farm.
For example, you have 10 Web servers, collect logs from all 10 servers, and using a single request you can search all logs from all 10 servers.
