monitor | If the NIC maintains its connection status, the agent reads the system-defined variable to determine the status of the resource. If the NIC does not maintain its connection status, the agent verifies that the NIC has been assigned an IP address, and sends a ping to all the hosts listed in the attribute PingHostList. The agent counts the number of packets received by the NIC before and after the ping. If the count increases, the resource is marked ONLINE. If the count remains unchanged, the agent broadcasts a UDP echo request to the address derived from the administrative IP address and the associated subnet mask. The agent counts the number of packets received by the NIC before and after the broadcast. If the count increases, the resource is marked ONLINE. If the count remains the same or decreases, the resource is marked FAULTED. The NIC agent also calculates the percentage of erroneous packets transmitted during each monitor interval. If this percentage exceeds the value in the MaxTxErrorPercentage attribute for the number of consecutive monitor intervals specified by the value in the MaxTxErrInterval attribute, the NIC resource is marked FAULTED. |
