esxi Dump collection on remote server?

Hi there,

This is related to vcenter/esxi 6. I want to send my esxi host core dumps to a remote server in case vCenter crashes.

Do I need to install the Dump Collector service on the remote server or just specify the remote IP address in the esxcli command on vCenter?

I don't get the option to install esxi core dump collector in the 6 iso media?

So, essentially, I want to send host dumps if vCenter crashes to a remote server.

Thanks!

VMware vSphere vCenter 6.0 - Dump Collector is now bundled and installed with vCenter and you won’t see them as separate line items in the vCenter installer.

Check the services on your Windows server, to check the service is started!

You then need to configure the service on ESXi, to send dumps and connect to the vCenter Server IP Address.

Thanks Andrew I'm still confused on this. How do we get the service running on the remote server if we can't install anything from the ISO? If I was running a Windows Based VC — in 5.5 I had the capability to install Dump Collector on a different server (and not neccesarily on VC server) … can this be done in VC6?

Is is just a matter of running these commands on the intended log destination host citing the vCenter IP address because I can't see any log service running on the intended destination host?

esxcli system coredump network get
esxcli system coredump network set -v vmk0 -i 192.168.9.16 -o 6500
esxcli system coredump network set -e true

okay, so let me rewind.....not understanding what you are trying to do here....

you don't want to send ESXi Host Dumps to vCenter Server ?

because Dump Collector is currently running on your vCenter 6.0 Server , providing you have started it

So, what I would like to do - whether or not it's possible is another thing - in a scenario in which vCenter itself crashes (or rather the host it resides on), is to have those logs saved to another remote server outside of vCenter. I can see the service on the vCenter Server but I want to do is set up the core dumps to go to another remote server in the case vCenter (the host on which it resides) itself were to go down.

What Is Threat Intelligence?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

Okay, firstly the Dump Collector, is used for ESXi logs to be sent to it.

Is the other server you have physical, because that host could also go down, if it's virtual ?

So I cannot see if it makes any difference if they are sent to vCenter Server or another server which is also hosted on an ESXi server, which is also a virtual server hosting Dump Collector.

It's going to be a physical server, Andrew. Is that possible?

The vSphere ESXi Dump Collector service is now integrated with vCenter Server.

if you have concerns about host crashing, I would install vCenter Server on a physical platform.

Also VMware, have made it known, at VMworld 2015, Barcelona, that the preferred management platform is now the Appliance, which also has Dump Collector integrated, and rumors are that vCenter Server for Windows, will be deprecated in the future, in favour of the appliance.

I get the Appliance is the Future vibe.

It should be theoretically possible, though, to set up a physical server to direct vCenter Server (ESXi host which it resides on) logs to dump to in the event it crashes?

Thanks for your input, Andrew.

Install it all again, on another server!
