Troubleshooting

Various issues arise as users work with the SNMP Probe (nco_p_mttrapd probe).

Using buffering to improve the performance of the probe

If the buffering facility is not used, the SNMP Probe queue increases in size until it is eventually exceeded.

The following example shows the log file messages that the probe writes to the log file as traps are received:



2015-07-09T17:57:26: Information: I-P_M-104-000: Number of items in the trap queue is 51451
2015-07-09T17:57:26: Information: I-P_M-104-000: Number of items in the trap queue is 51454
2015-07-09T17:57:26: Information: I-P_M-104-000: Number of items in the trap queue is 51453
2015-07-09T17:57:26: Information: I-P_M-104-000: Number of items in the trap queue is 51452
2015-07-09T17:57:26: Information: I-P_M-104-000: Number of items in the trap queue is 51451
2015-07-09T17:57:26: Information: I-P_M-104-000: Number of items in the trap queue is 51450
2015-07-09T17:57:26: Information: I-P_M-104-000: Number of items in the trap queue is 51449
2015-07-09T17:57:26: Information: I-P_M-104-000: Number of items in the trap queue is 51449

If there are a high number of traps in the probe's queue (as there are in the example above), the probe will run more slowly. To reduce the size of the queue and thus improve the performance of the probe, you should use the buffering facility.
