Ensuring Quality Outcomes by Reducing EHR system Downtime

Theresa Miller - Thu, 02/07/2019 - 06:30

EHR implementations are typically a huge undertaking for the healthcare organizations.  In some cases, deployments can take more than a year, and the cost implication is millions of dollars.  No small task of any kind, but when it comes down to monitoring sometimes only standard monitoring tools are deployed to reduce cost.  Today we will […]

Theresa Miller - Tue, 12/11/2018 - 06:30

Many home users of Microsoft products almost take for granted their Windows Update will operate correctly.  For those of you keeping score, Microsoft pulled the Windows Update from October 2018 because it was unexpectedly deleting user files.  To finish the year with a bang, Microsoft pulled yet another failed Windows Update in December of 2018 to end […]

Looking at the Hyper-V Event Log (January 2018 edition)

Microsoft Virtualisation Blog - Tue, 01/23/2018 - 22:57

Hyper-V has changed over the last few years and so has our event log structure. With that in mind, here is an update of Ben’s original post in 2009 (“Looking at the Hyper-V Event Log”).

This post gives a short overview on the different Windows event log channels that Hyper-V uses. It can be used as a reference to better understand which event channels might be relevant for different purposes.

As a general guidance you should start with the Hyper-V-VMMS and Hyper-V-Worker event channels when analyzing a failure. For migration-related events it makes sense to look at the event logs both on the source and destination node.

Below are the current event log channels for Hyper-V. Using “Event Viewer” you can find them under “Applications and Services Logs”, “Microsoft”, “Windows”.
If you would like to collect events from these channels and consolidate them into a single file, we’ve published a HyperVLogs PowerShell module to help.

Event Channel Category Description Hyper-V-Compute Events from the Host Compute Service (HCS) are collected here. The HCS is a low-level management API. Hyper-V-Config This section is for anything that relates to virtual machine configuration files. If you have a missing or corrupt virtual machine configuration file – there will be entries here that tell you all about it. Hyper-V-Guest-Drivers Look at this section if you are experiencing issues with VM integration components. Hyper-V-High-Availability Hyper-V clustering-related events are collected in this section. Hyper-V-Hypervisor This section is used for hypervisor specific events. You will usually only need to look here if the hypervisor fails to start – then you can get detailed information here. Hyper-V-StorageVSP Events from the Storage Virtualization Service Provider. Typically you would look at these when you want to debug low-level storage operations for a virtual machine. Hyper-V-VID These are events form the Virtualization Infrastructure Driver. Look here if you experience issues with memory assignment, e.g. dynamic memory, or changing static memory while the VM is running. Hyper-V-VMMS Events from the virtual machine management service can be found here. When VMs are not starting properly, or VM migrations fail, this would be a good source to start investigating. Hyper-V-VmSwitch These channels contain events from the virtual network switches. Hyper-V-Worker This section contains events from the worker process that is used for the actual running of the virtual machine. You will see events related to startup and shutdown of the VM here. Hyper-V-Shared-VHDX Events specific to virtual hard disks that can be shared between several virtual machines. If you are using shared VHDs this event channel can provide more detail in case of a failure. Hyper-V-VMSP The VM security process (VMSP) is used to provide secured virtual devices like the virtual TPM module to the VM. Hyper-V-VfpExt Events form the Virtual Filtering Platform (VFP) which is part of the Software Defined Networking Stack. VHDMP Events from operations on virtual hard disk files (e.g. creation, merging) go here.

Please note: some of these only contain analytic/debug logs that need to be enabled separately and not all channels exist on Windows client. To enable the analytic/debug logs, you can use the HyperVLogs PowerShell module.

Alles Gute,

Lars
