 Anecdote by @Kiran Surya 

 

Nutanix users and administrator are often required to access the CVMs, Hypervisors and IPMIs through their IP addresses.  The most commonly used method to look at the IP addresses of these three entities is through Prism Element, and going through the Hardware tabs.  However, looking through the GUI can be time consuming since you are required to click on every Host to view the IP address details of all three components.  It’s all the more cumbersome if you have a huge infrastructure, like say 24 Hosts.  It would be ideal if there is an easier process to list all these pieces of vital information.  

 

I happen to use the following combination of characters to list all these three pieces of data, and needless to say the customers are delighted when they see me run this command:


 

nutanix@NTNX-7B43JB2-A-CVM:10.171.154.127:~$

nutanix@NTNX-7B43JB2-A-CVM:10.171.154.127:~$ echo; set `ncli host list | grep Address | sed 's/^.*: //'`;echo -e "    IPMI\t    CVM\t\tHypervisor";echo -e "    ----            ---         ----------";c=0;for f in $@;do echo -ne "$f\t";((c = c + 1));if o $((c%3)) -eq 0 ];then echo;fi;done; echo; echo

The above command essentially parses through the often used $ncli host list  command output, handpicks the IP addresses from each Host and lists them as shown above.  This comes in especially handy when a customer is working with a Nutanix Technical Support engineer and they are trying to figure out the individual pieces of a Host while doing a hardware replacement like DIMM, or if they are trying to submit a report to the upper Management on the resources being used.

 

Hope you get this command the next time you work at the CLI on your Nutanix cluster infrastructure.
