VM won’t vMotion on Nutanix Cluster – Error: msg.vmk.status.VMK_BUSY

April 19, 2016November 5, 2022Tristan Self

To resolve this I used: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1031636 even though this is for version 4.x this worked for VMware 5.5. On the host under advanced settings change this setting: Migrate.VMotionResolveswaptype = 1 Change the […]

Using check_snmp to check if a metric is within a range or not

February 18, 2016November 5, 2022Tristan SelfLeave a Comment

Sometimes a metric needs to fall between a range to be considered OK, and outside the range (i.e. above and below) for a warning, and outside that range (i.e. above and below) for a critical. So for example monitoring the input voltage into a APC UPS to ensure it is within a certain range. So […]

When attempting to add a VMWare vCenter Server Appliance to our Active Directory I encountered this error message: “Error: Invalid Active Directory Domain”. Within the /var/log/vmware/vpx/vpxd_cfg.log log file I was seeing the following: It would seem that the root record for the domain is missing, this should resolve to a domain controller, so it has […]

VMware Transparent Page Sharing – Is it on? How much RAM is it saving?

January 2, 2016November 5, 2022Tristan Self

VMWare TPS (Transparent Page Sharing) is a mechanism within the hypervisor to allow the saving of RAM by allowing virtual machines where their memory matches to only store a copy of the memory used once. I.e. If you had 5 Windows 2012 R2 virtual machines running, they are going to be almost completely identical, so […]

Automating VMware Memory Changes

December 2, 2015November 5, 2022Tristan Self

I had to make some memory changes on a batch of VMs. I didn’t want to have to manually shutdown each VM, alter the memory setting and then restart as this would be very time consuming instead I prepared this script. You first need to create a CSV file, e.g. vmalterlist.csv and place it somewhere on […]

If you have a webserver that you want to check, but it requires authentication, you can still perform a check without seeing an error code. So for example, if you had a webserver where you wanted to check that the web server was responding on port 80, but didn’t want to have the plugin login […]
