ALM-12047 Read Packet Error Rate Exceeds the Threshold (For MRS 2.x or Earlier)

Description

The system checks the read packet error rate every 30 seconds. This alarm is generated when the read packet error rate exceeds the threshold (the default threshold is 0.5%) for multiple times (the default value is 5).

You can change the threshold by choosing System > Threshold Configuration > Device > Host > Network Reading > Network Read Packet Rate Information > Read Packet Error Rate.

If the hit number is 1, this alarm is cleared when the read packet error rate is less than or equal to the threshold. If the hit number is greater than 1, this alarm is cleared when the read packet error 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

Specifies the threshold for triggering the alarm.

Impact on the System

The communication is intermittently interrupted, and services time out.

Possible Causes

  • The alarm threshold is improperly configured.
  • The network environment is abnormal.

Procedure

Check whether the threshold is set properly.

  1. Log in to MRS Manager and check whether the threshold (configurable, 0.5% by default) is appropriate.

    • If yes, go to 4.
    • If no, go to 2.

  2. Choose System > Threshold Configuration > Device > Host > Network Reading > Network Read Packet Rate Information > Read Packet Error Rate and change the alarm threshold based on the actual service usage.
  3. Wait 5 minutes and check whether the alarm is cleared.

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

Check whether the network is normal.

  1. Contact the system administrator to check whether the network is normal.

    • If yes, rectify the network fault and go to 5.
    • If no, go to 6.

  2. Wait 5 minutes and check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to 6.

  3. Collect fault information.

    1. On MRS Manager, choose System > Export Log.
    2. Contact the O&M engineers and send the collected logs.
