Buffer Allocation Failures (A3Com)

System.NetworkManagement.A3Com.Memory.BufferAllocationFailures (UnitMonitor)

Monitors the level of buffer allocation failures on the network device

Knowledge Base article:

Summary

The monitor indicates the number of memory buffer allocation failures on this device. This monitor has two possible states:

Configuration

The following options can be configured on this monitor:

Option

Definition

Default

Interval

Amount of time in seconds between checks of the device status

240 seconds

Number of retries

Number of attempts in each monitoring interval before the interval's sample is discarded

3

Number of samples

Number of consecutive samples before the monitor changes state

3

Timeout

Amount of time in milliseconds to wait for a response from the device before the sample times out and a new attempt is made to sample the value

3,500 milliseconds

Threshold

Number of buffer allocation failures

0

Causes

This monitor enters an error state when the number of memory buffer allocation failures exceeds the configured threshold. The default is 0.

Resolutions

Use the Health Explorer to check the details for the state change on the State Change Events tab for the monitor. This data shows the calculated performance counter value that caused the health state change. Consult the device manufacturer's documentation for more information on the problem and troubleshooting procedures.
