Sorry for the gap in posting…well…anything… New role has kept me very busy!
Most of us will have our own little tips and tricks on troubleshooting, but recently I had a customer who had a machine hanging, that looked suspiciously like VMware Tools was causing an issue, but they had no idea how to troubleshoot. I’d suggested various options, including simply getting the logs, checking ESXi services and so on and it wasn’t anything they’d had to do before, so I really needed something quick and fully features to suggest to them. There’s a great VMware KB which uses the process of:
Validate the scope – find out the scope of the problem and accurately define what the symptoms are (no point in just having someone screaming “It’s crashing, IT’S CRASHING!”
Identify the cause – so many possibilities! Storage, services crashing, resource contention, a task on the VM…
Action Plan – Take action to remediate the issue – once the cause has been established, focus on what is causing the issue and define a plan to resolve it.
