PerfNic-Check

Checks transfer and errors per physical port (nic_common).

Usage

$ check_netapp_pro.pl PerfNic -H <host> [-z rx_crc_errors|total_bytes|...] [...] [--help]

Description

This plugin checks various performance counters of a NetApps physical network interface (NIC). Among them several crc/transmit-error-counters to detect errors on the physical network-layer.

BETA-RELEASE WARNING:

the following counters are of type delta and their math may be wrong. Please report if you have doubts about their results:

rx_crc_errors
rx_total_bytes
tx_hw_errors

A complete list of supported counters is printed via the --counter switch.

Hint: Calling the getter with the switch --discover=counters will explain each available counter in detail.

Simple Examples

[S1] ./check_netapp_pro.pl PerfNic -H filer --explore=counters

List all available counters.

Counters (unit) supported by nic_common:
 instance_name (-)
 instance_uuid (-)
 node_name (-)
 rx_bytes (B/s)
 rx_crc_errors (-)
 rx_errors (B/s)
 rx_frames (/s)
 rx_total_bytes (-)
 total_bytes (B/s)
 total_errors (B/s)
 tx_bytes (B/s)
 tx_errors (B/s)
 tx_frames (/s)
 tx_hw_errors (-)

[S2] ./check_netapp_pro.pl PerfNic -H filer

Checks all interfaces using the default thresholds.
