Introduction

This chapter describes the logs available with the Oracle Communications Session Border Controller and explains how to access and view them. It also explains the relationship between logs and system events.

About Logs

Logs are a critical component of system management and security. You can use the information in logs to assist real-time debugging and management, and to track potential security breaches or other nonstandard activities on the system. The Oracle Communications Session Border Controller supports the following three types of logs:

• acmelog (syslog): contains both generic messages (not task oriented) as well as system log messages
• process logs: contain process flow from tasks
• transaction logs: contain raw messages about protocol transactions sent and received by the Oracle Communications Session Border Controller.

The Oracle Communications Session Border Controller supports SYSLOG, a protocol that lets the Oracle Communications Session Border Controller log significant system information to a remote server.

Logging Events

The Oracle Communications Session Border Controller can log events that occur on different system components, such as those associated with a protocol transaction. If logging is enabled on the system, monitored events are evaluated against the logging level set for the component that sent the event. Events that meet the logging level are written to a log file.

SNMP traps are sent when an Oracle Communications Session Border Controller generates a system log (acmelog) message and the following conditions are present:

• SNMP is enabled.

  Set the system configuration’s SNMP functionality to enabled. Using the ACLI, set the snmp-enabled field for system-config to enabled.

• Sending system log (acmelog) notifications to an NMS using SNMP is enabled.

  Set the system configuration’s log functionality to enabled. Using the ACLI, set the enable-snmp-syslog-notify field for system-config to enabled.

• Severity level that identifies at which severity level syslog notifications are sent is configured. For example:

  Set the system configuration’s log functionality to one of the possible severity levels. Using the ACLI, set the snmp-syslog-level field for system-config to enabled.

See the ACLI Configuration Guide for details about configuring the Oracle Communications Session Border Controller and the ACLI Reference Guide for details about using the ACLI.
