ALM-12049 Network Read Throughput Rate Exceeds the Threshold

Description

The system checks the network read throughput rate every 30 seconds and compares the actual throughput rate with the threshold (the default threshold is 80%). This alarm is generated when the system detects that the network read throughput rate exceeds the threshold for several times (5 times by default) consecutively.

To change the threshold, choose System > Threshold Configuration > Device > Host > Network Reading > Network Read Throughput Rate > Read Throughput Rate.

When the hit number is 1, this alarm is cleared when the network read throughput rate is less than or equal to the threshold. When the hit number is greater than 1, this alarm is cleared when the network read throughput rate is less than or equal to 90% of the threshold.

Parameters

Parameter

Description

ServiceName

Specifies the service for which the alarm is generated.

RoleName

Specifies the role for which the alarm is generated.

HostName

Specifies the host for which the alarm is generated.

NetworkCardName

Specifies the network port for which the alarm is generated.

Trigger Condition

Generates an alarm when the actual indicator value exceeds the specified threshold.

Impact on the System

The service system runs improperly or is unavailable.

Possible Causes

  • The alarm threshold is set improperly.
  • The network port rate cannot meet the current service requirements.

Procedure

Check whether the threshold is set properly.

  1. Log in to MRS Manager and check whether the alarm threshold is set properly. (By default, 80% is a proper value. However, users can configure the value as required.)

  2. Based on actual usage condition, choose System > Threshold Configuration > Device > Host > Network Reading > Network Read Throughput Rate > Read Throughput Rate to modify the alarm threshold.
  3. Wait 5 minutes and check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 4.

Check whether the network port rate can meet the service requirements.

  1. On MRS Manager, click the alarm in the real-time alarm list. In the Alarm Details area, obtain the IP address of the host and the network port name for which the alarm is generated.
  2. Use PuTTY to log in to the host for which the alarm is generated as user root.
  3. Run the ethtool network port name command to check the maximum speed of the current network port.

    NOTE:

    In the VM environment, you cannot run a command to query the network port rate. It is recommended that you contact the system administrator to confirm whether the network port rate meets the requirements.

  4. If the network read throughput rate exceeds the threshold, contact the system administrator to increase the network port rate.
  5. Check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 10.

Collect fault information.

  1. On MRS Manager, choose System > Export Log.
  2. Contact technical support engineers for help, detail see technical support.
