Monitors the level of input error packets on this device
The monitor indicates the level of input packet errors on this device. This monitor has two possible states:
Healthy: The number of input packet errors is below the threshold.
Warning: The number of input packet errors exceeds the threshold.
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 | Percentage of error packets. | 10 |
This monitor enters a warning state when the percentage of input packet errors is greater than the error threshold configured for this interface (the default is 10%). The input packet error percentage is derived by dividing the number of input packets in error by the total number of input packets. The result of this calculation is expressed as a percentage and compared to the error threshold.
The input packet rate must be greater than or equal to the minimum packet rate. The minimum packet rate is derived by dividing the speed of the interface by the value of its maximum transfer unit (MTU) and multiplying the result by the error traffic threshold.
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.
