vSphere PowerCLI Scripts for Syslog and SSH

PowerCLIScripting and automation are ashamedly new territories for me. I’ve heard enough clarion calls to grow and develop personally and professionally, though, that I know I have to gain ground here. Hopefully this is the first step in building my knowledge base of such tools.

In this entry, I need to solve for two configuration tasks.

Syslog

First, I am concluding an evaluation of Splunk and need to reset my vSphere ESXi 5.5 hosts’ syslog global log hosts to only our existing syslog server. My inclination was to click through the vSphere Client and change it host by host, as it would have taken less time than it has to write the words in the post so far. However, as I am in search of a new syslog solution, possibly VMware LogInsight, I know I will need to do this again.

Migrating VMs between vSphere Datacenters

As part of a project consolidating mission critical services, I am moving a few VMs between vSphere / vCenter datacenters. The keyword here is “datacenters” and for emphasis, they are managed by different vCenter servers operating in linked mode. Because of this setup, the migration isn’t a simple cluster & storage vMotion.

Here’s the process I am following. I hope it helps; if you use another method, feel free to comment.

migrate_services1. Enable SSH on an ESXi host in the source and destination cluster; on the source host, also open SSH outbound on the host firewall

  • In vSphere Client, go to the “Configuration” tab on each host
  • Under “Software” on the left side of the right pane, select “Security Profile”
  • In the top right under “Services”, click “Properties…”
  • Scroll down to “SSH” and click “Options…”
  • Select “Start and stop manually”, then click “Start” and return to the Security Profile page
  • On the source ESXi host, also click “Properties…” under “Firewall”
  • In Firewall Properties, check “SSH Client” and click “OK”
