Q: How to verify hardware health status on NetScaler MPX?

A: stat system -detail command to display the current health attributes of different NetScaler hardware component.
For a list of health attributes and their recommended value ranges, refer to Citrix Documentation - Hardware Health Attributes.

Run the following commands to check on NetScaler (deprecated) :
> shell
root@Netscaler# ns_hw_err.bash

WARNING:  DO NOT run the ns_hw_err.bash script on a FIPS Netscaler.  This script contains commands that can cause a FIPS Netscaler to hang or crash, requiring a power cycle to recover.  

NOTE:  The ns_hw_err.bash script was intended for Netscaler Tech Support use only.  As such, it can sometimes report false positives that should be ignored.  Examples of false positives are cavium card timeout recoveries and SMART Old-Age warnings.  Both of these conditions are considered normal and are not indicative of a hardware failure, nor do they require an RMA.

In lieu of the script above, RECOMMENDED method of performing a health check on a Netscaler is to generate a tech support file (from the GUI or by running show techsupport from the CLI) and uploading the resulting support.tgz file (in /var/tmp/support) to https://cis.citrix.com for analysis.  CIS will analyze the file and generate a report detailing the Netscaler's health and also providing suggestions for improvement.
