You can configure ESXi to dump the vmkernel memory to a network server, rather than to a disk, when the system has encountered a critical failure. Install vSphere ESXi Dump Collector to collect such memory dumps over the network.
For instructions on configuring ESXi to dump kernel memory to the network server, see the information about configuring the vSphere ESXi Dump Collector with esxcli in the vSphere Installation and Setup documentation.
The vSphere ESXi Dump Collector is most useful for datacenters where ESXi hosts are configured using the Auto Deploy process, so the ESXi hosts might not have local storage. You can also install the vSphere ESXi Dump Collector for ESXi hosts that do have local storage, as an additional location where vmkernel memory dumps can be redirected when critical failures occur.
You can install the vSphere ESXi Dump Collector on the same machine as the associated vCenter Server, or on a different machine that has network connection to the vCenter Server.
The vSphere ESXi Dump Collector service binds to an IPv4 address for communication with vCenter Server, and does not support IPv6. The vCenter Server can be on a host machine in an IPv4-only, IPv4/IPv6 mixed-mode, or IPv6-only network environment, but the machine that connects to the vCenter Server through the vSphere Web Client must have an IPv4 address for the vSphere ESXi Dump Collector service to work.
- Verify that you have administrator privileges
- Verify that the host machine has Windows Installer 3.0 or later.
- Verify that the host machine has a supported processor and operating system. The vSphere ESXi Dump Collector supports the same processors and operating systems as vCenter Server. See vCenter Server Software Requirements and Hardware Requirements for vCenter Server, the vSphere Web Client, vCenter Inventory Service, and vCenter Single Sign-On.
- Verify that the host machine has a valid IPv4 address. You can install the vSphere ESXi Dump Collector on a machine in an IPv4-only or IPv4/IPv6 mixed-mode network environment, but you cannot install the vSphere ESXi Dump Collector on a machine in an IPv6-only environment.
- If you are using a network location for the Dump Collector repository, make sure the network location is mounted.
Gather the following information to complete the installation or upgrade:
- The location to install the vSphere ESXi Dump Collector to, if you are not using the default location.
- The location for the vSphere ESXi Dump Collector repository where the dump files will be stored.
- (Optional) The maximum size for the vSphere ESXi Dump Collector repository. The specified network location must have at least that much free space.
- Whether to install the vSphere ESXi Dump Collector as a standalone instance or to integrate the vSphere ESXi Dump Collector with a vCenter Server. The vSphere ESXi Dump Collector is not supported for integration with vCenter Server versions earlier than version 5.0.
- If the vSphere ESXi Dump Collector is integrated with a vCenter Server, the address and credentials for the vCenter Server: IP address or name, HTTP port, user name, and password.
- The vSphere ESXi Dump Collector server port, if you are not using the default setting.
- The host name or IP address to identify the vSphere ESXi Dump Collector on the network.
- The credentials of a user authorized to register or update the vSphere ESXi Dump Collector extension with vCenter Server.
