Monitoring CPU usage

Configuring CPU usage alarm

About this task

The device samples CPU usage at 1-minute intervals, and compares the samples with CPU usage thresholds to identify the CPU usage status and send alarms or notifications accordingly.

The device supports the following CPU usage thresholds:

·     Minor threshold—If the CPU usage increases to or above the minor threshold but is less than the severe threshold, the CPU usage enters minor alarm state. The device sends minor alarms periodically until the CPU usage increases above the severe threshold or the minor alarm is removed.

·     Severe threshold—If the CPU usage increases above the severe threshold, the CPU usage enters severe alarm state. The device sends severe alarms periodically until the severe alarm is removed.

·     Recovery threshold—If the CPU usage decreases below the recovery threshold, the CPU usage enters recovered state. The device sends a recovery notification.

CPU usage alarms and notifications can be sent to NETCONF, SNMP, and the information center to be encapsulated as NETCONF events, SNMP traps and informs, and log messages. For more information about NETCONF and SNMP, see Network Management and Monitoring Configuration Guide. For more information about information center, see "Configuring the information center."

Configuring CPU usage tracking

About this task

After you enable CPU usage tracking, the system samples CPU usage at intervals and saves the samples to a buffer. You can use the display cpu-usage history command to view the recent CPU usage.

Procedure

1.     Enter system view.

system-view

2.     Set the sampling interval for CPU usage tracking.

monitor cpu-usage interval interval [ slot slot-number [ cpu cpu-number ] ]

By default, the sampling interval for CPU usage tracking is 1 minute.

Monitoring memory usage

Setting memory alarm thresholds

About this task

To ensure correct operation and improve memory efficiency, the system monitors the amount of free memory space in real time. If the amount of free memory space reaches the minor, severe, or critical alarm threshold, the system issues an alarm to affected service modules and processes.

(On devices that do not support low memory.) You can use the display memory command to display memory usage information.

(On devices that support low memory.) The system monitors only the amount of free low-memory space. You can use the display memory command to display memory usage information.

(On devices with slots that support low memory.) For slots that support low memory, the system monitors only the amount of free low-memory space. You can use the display memory command to display memory usage information. If the LowMem field is displayed for a slot, the slot supports low memory.

The early warning feature warns you of an approaching insufficient-memory condition.

As shown in Table 1 and Figure 3, the system supports the following free-memory thresholds:

·     Sufficient-memory threshold.

·     Early-warning threshold.

·     Normal state threshold.

·     Minor alarm threshold.

·     Severe alarm threshold.

·     Critical alarm threshold.

Table 1 Memory alarm notifications and memory alarm-removed notifications

Notification	Triggering condition	Remarks
Early-warning notification	The amount of free memory space decreases to or below the early-warning threshold.	After generating and sending an early-warning notification, the system does not generate and send any additional early-warning notifications until the early warning is removed.
Minor alarm notification	The amount of free memory space decreases to or below the minor alarm threshold.	After generating and sending a minor alarm notification, the system does not generate and send any additional minor alarm notifications until the minor alarm is removed.
Severe alarm notification	The amount of free memory space decreases to or below the severe alarm threshold.	After generating and sending a severe alarm notification, the system does not generate and send any additional severe alarm notifications until the severe alarm is removed.
Critical alarm notification	The amount of free memory space decreases to or below the critical alarm threshold.	After generating and sending a critical alarm notification, the system does not generate and send any additional critical alarm notifications until the critical alarm is removed.
Critical alarm-removed notification	The amount of free memory space increases above the severe alarm threshold.	N/A
Severe alarm-removed notification	The amount of free memory space increases above the minor alarm threshold.	N/A
Minor alarm-removed notification	The amount of free memory space increases above the normal state threshold.	N/A
Early-warning-removed notification	The amount of free memory space increases above the sufficient-memory threshold.	N/A

Verifying and diagnosing transceiver modules

Verifying transceiver modules

About this task

You can use one of the following methods to verify the genuineness of a transceiver module:

·     Display the key parameters of a transceiver module, including its transceiver type, connector type, central wavelength of the transmit laser, transfer distance, and vendor name.

·     Display its electronic label. The electronic label is a profile of the transceiver module and contains the permanent configuration, including the serial number, manufacturing date, and vendor name. The data was written to the transceiver module or the device's storage component during debugging or testing of the transceiver module or device.

The device regularly checks transceiver modules for their vendor names. If a transceiver module does not have a vendor name or the vendor name is not H3C, the device repeatedly outputs traps and log messages. For information about logging rules, see "Configuring the information center."
