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."

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.
As shown in Table 1 and Figure 2, the system supports the following free-memory thresholds:
· Normal state threshold.
· Minor alarm threshold.
· Severe alarm threshold.
· Critical alarm threshold.
Table 1 Memory alarm notifications and memory alarm-removed notifications

Triggering condition |
Remarks |
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. |

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."
Procedure
To verify transceiver modules, execute the following commands in any view:
· Display the key parameters of transceiver modules.
display transceiver interface [ interface-type interface-number ]
· Display the electrical label information of transceiver modules.
display transceiver manuinfo interface [ interface-type interface-number ]
Diagnosing transceiver modules
About this task
The device provides the alarm and digital diagnosis functions for transceiver modules. When a transceiver module fails or is not operating correctly, you can perform the following tasks:
· Check the alarms that exist on the transceiver module to identify the fault source.
· Examine the key parameters monitored by the digital diagnosis function, including the temperature, voltage, laser bias current, TX power, and RX power.
Procedure
To diagnose transceiver modules, execute the following commands in any view:
· Display transceiver alarms.
display transceiver alarm interface [ interface-type interface-number ]
· Display the current values of the digital diagnosis parameters on transceiver modules.
display transceiver diagnosis interface [ interface-type interface-number ]
Enabling alarm upon detection of a third-party transceiver module
About this task
Upon installation of a transceiver module, the system reads vendor information from it to determine whether it is a third-party transceiver module. If it is a third-party module, the device sends a trap notification and a log message to notify the user of replacing it with an H3C transceiver module. You can use display transceiver manuinfo to obtain vendor information for a transceiver module.
Procedure
1. Enter system view.
system-view
2. Enable alarm upon detection of a third-party transceiver module.
