Commands for Status Monitoring and Statistics 8 This chapter describes commands for: • Configuring and managing the Event Management System/Logging • Configuring and monitoring system health and statistics • Enabling and disabling the collection of remote monitoring (RMON) statistics on the switch • Enabling, disabling, and configuring sFlow® statistics collection Event Management System When an event occurs on a switch, the Event Management System (EMS) allows you to send messages generated by these events to a specified log target. You can send messages to the memory buffer, NVRAM, the console display, the current session, to a syslog host, or to the other Management Switch Fabric Module (MSM) or Management Module (MM). The log messages contain configuration and fault information pertaining to the device. You can format the log messages to contain various items of information, but typically a message consists of: • Timestamp-The timestamp records when the event occurred. • Severity level: • Critical-A desired switch function is inoperable. The switch may need to be reset. • Error-A problem is interfering with normal operation. • Warning-An abnormal condition exists that may lead to a function failure. • Notice-A normal but significant condition has been detected; the system is functioning as expected. • Info-Actions and events that are consistent with expected behavior. • Debug-Summary, Debug-Verbose, and Debug-Data-Information that is useful when performing detailed trouble shooting procedures. By default, log entries that are assigned a critical, error, or warning level are considered static entries and remain in the NVRAM log target after a switch reboot. • Component-The component refers to the specific functional area to which the error refers.
