BufferCache-Check

Checks several metrics of the system buffer cache (=system memory)

Usage

Description

This plugin checks various performance counters of the NetApp-system.

A 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 BufferCache -H filer --explore=counters

List all available and supported counters on the target system.
