The CLI Shows That the Device CPU Usage, Memory Usage, and Temperature Are Low but a Threshold Exceeding Alarm Is Generated on the SNC

The CLI Shows That the Device CPU Usage, Memory Usage, and Temperature Are Low but a Threshold Exceeding Alarm Is Generated on the SNC

For all faults that information on the SNC is inconsistent with that on the CLI, rectify the faults as follows and use the MIB tool to obtain the oid value:

1. The value returned by the MIB tool is always high. Use the MIB tool to obtain the oid values of the CPU, memory, and temperature for verification.

CPU OID: .1.3.6.1.4.1.4881.1.1.10.2.36.1.1

Memory OID: .1.3.6.1.4.1.4881.1.1.10.2.35.1.1.1

Temperature OID in sequence: 1.3.6.1.4.1.4881.1.1.10.2.1.1.16.0 /1.3.6.1.4.1.4881.1.1.10.2.1.1.44.1.5/ 1.3.6.1.4.1.4881.1.1.10.2.1.1.23.1.3

Countermeasure: Reach out to us on Skype (Skype account :service_rj@ruijienetworks.com) at any time for assistance.

2. The CPU usage, memory usage, and temperature soar instantaneously but the values returned by the MIB tool are within the normal range. Start packet capture on the SNC server to capture SNMP packets. Determine the observation period based on the fault occurrence frequency and analyze the SNMP packets that are captured in the observation period to check whether the CPU usage, memory usage, and temperature soar instantaneously.

Countermeasure: None. It reflects the real status of the device. If the alarm can be ignored, you can cancel performance monitoring of the device.
