Virtualization, Cloud, Infrastructure and all that stuff in-between

My ramblings on the stuff that holds it all together

Where are the vCAC log files

I’ve had some SRs open with VMware GSS lately on some vCAC issues, and the first thing they usually ask for is logs – to save yourself (and GSS) some time it’s worth gathering up the following logs and providing them immediately when you open your SR (using the upload tool) – this helps GSS to hit the ground running with your issue


Log description Log File Name Default Location
vCAC Installation log MMDDYYHHMMSS.txt c:\vcacLog
vCAC Server (everything) log All.log C:\Program Files (x86)\VMware\vCAC\Server\Logs
vCAC Server (errors only) log Error.log C:\Program Files (x86)\VMware\vCAC\Server\Logs
vCAC Agent logs vSphereAgent.log (name based on Agent type) C:\Program Files (x86)\VMware\vCAC\Agents\<AgentName>\logs

How to monitor what your vCAC IaaS Server is doing in real-time

vCAC is a complex product with a lot of moving parts, it’s a pain to have to switch back & forth between monitoring views in the UI.

The IaaS server is a Windows box, and does most of the heavy lifting so you can’t just SSH in and tail a log file (well, you sort of could…  but)

I like to have all this info on a secondary monitor scrolling past in realtime, mainly so I can look like I am in the Matrix but it’s useful when you’re trying to debug a weird edge-case that only happens in real-time, I achieve this by..

Using mTail on my Windows administrative workstation.

Mapping a drive to the C$ share on my IaaS server

Open the following log files in mTail and put it on a secondary monitor so I can watch what’s going on in real-time (don’t forget to hit start to monitor the file)

\\IaaSserver\c$\Program Files (x86)\VMware\vCAC\Agents\<NAME OF YOUR AGENT(S)>\logs\vSphereAgent.log

\\IaaSserver\c$\c$\Program Files (x86)\VMware\vCAC\Server\Logs\All.log

For good measure you can also open your vCenter log files in the same way if you want to.

Handy hint – if you are tryign to catch a specific errror in the noise of the logs, check the Filter box and put the search expression in – then it will only show when that message occurs in the logs (like doing tail –f <file> | grep “string” in *NIX). you can use the following strings to limit to certain message categories.




Unable to launch the application when trying to connect to vCO client


if you’re using the vCAC vCenter Orchestrator (vCO) client to customise a workflow it uses a Java client.

If you recently updated or downloaded Java to your machine then you’ll see the following error message..

This is because it is using a self-signed certificate, and the latest Java builds prevent this as a security measure, reasonable I guess.

You’ll need to add your vCAC appliance URL to the exception list, note you need to specify the port number, or it won’t work. you can set this ON YOUR CLIENT WORKSTATION via Control Panel –> Java / Security on a Windows machine.


And you will now be able to connect, albeit with some warnings from the Java client..  (as shown below)


The moral of the story is, Java may run on 3 billion devices, but all of them break in subtle ways, each & every time when you update something 🙂
