PerfIf-Check

Checks transfer and errors per ethernet interface.

Usage

$ check_netapp.pl PerfIf -H <hostname|IP> -u <user%pass> -z recv_data|send_data|recv_errors|... -w  -c [--help] [...]

Description

This plugin checks various performance counters of a NetApps ethernet
interface.

The counters supported by this plugin are: recv_drop_packets, recv_mcasts,
recv_data, collisions, send_packets, send_mcasts, recv_errors, send_errors,
send_data, recv_packets


WHICH COUNTERS CAN I MONITOR?

Short answer: use --explore=counters

Long answer: Not all counters are supported on every system. The plugin
will tell you, if you have chosen a non-existing counter and exit with
UNKNOWN. To get a list of supported counters, available on the particular
system use --explore=counters.


Performance-data will be printed for all checked interfaces.


Consider using -v for debugging, if you are not satisfied with the result.

Simple Examples

Note: The '-u' switch is missing in all the following examples, so the filer-credentials are taken from the default-file: '/usr/local/nagios/etc/netapp_credentials'

$ check_netapp PerfIf -H filer -z recv_data -w 2000B/s -c 3000B/s -n e0c

Check the data received on interface e0c - warn if data rate is greater than 2000 Byte per second, exit critical if data rate is greater than 3000.

$ check_netapp PerfIf -H filer -z recv_data -w 2000 -c 3000 -n e0c

Same as above, but auto-detecting the unit.Please read the help section about --warning to understand the effect this feature might have on the performance.

$ check_netapp PerfIf -H filer -z recv_errors -w 20/s -c 50/s

Warn if more than 20 errors per second when receiving packets.

Advanced Examples

Note: Host- and credential-arguments are omitted. So you have to fill in -H and -u % for '...' in the examples below. Instead of '-u %' you can use '-f auth.txt' to read the credentials from a plain text-file.

$ check_netapp PerfIf -H filer --explore=counters

List all available interface counters on the target system.

$ check_netapp PerfIf -H filer --explore=instances

List all available interfaces on the target system.

$ check_netapp PerfIf -H filer -z recv_errors -w 20/s -c 50/s -I ^e\d

Check all interfaces, whose name starts with 'e' followed by a number. Eg. e0a, e0b, e1a, ...Please read the help of the Usage-module for more examples about the --include and --exclude-switches.
