Hi people,

Can anyone please suggest me what is the best way to configure all of my ESXi servers to forward all of the logs to a syslog server ?

Does VMware has their own SysLog server that can be utilized with no additional cost ?

The purpose is to capture all of the server logs before it gets rolled over for further diagnostic.

VMware does supply a Syslog server on the vCenter Server installation media.

You can also purchase Log Insight see here

http://www.vmware.com/products/vrealize-log-insight

this has a graphical interface similar to Splunk.

As for configuring for a Syslog Server, you just change the Advanced Settings.

see here

So in this case the data will be send over to my Windows VCenter server which will be saved in separate VMDK disk.

Is that possible or is there a u better alternative deployment ?

Yes, you can save it in separate drive (VMDK), please refer to below picture and change the Drive source,

can I repoint it into a NAS device so the drive is mapped using CIFS share inside the VCenter ?

You can use vCenter Server, and install the Syslog Server.

The syslog files just appear as very large text files.

If you require a GUI, I would recommend Log Insight, which is a separate appliance.

You can do different methods, you can use a Syslog Server, or you can change the location of the persistent logs to a datastore, either iSCSI or NFS.

You can then share this NFS export on your NAS, so you can inspect the logs.

This does not require a Syslog.

It's not really built in, it's a separate installation, and not very advanced application, when it comes to Syslogs.

You will see, when you look through your syslogs, you'll get a lot of noise!
