Here is an alternative method of extracting the super useful information from VIN (vSphere Infrastructure Navigator) which I stumbled across while troubleshooting an earlier VIN 1.2 deployment. This method is much simpler from a data extraction point of view and has less prerequisites compared to the first method documented here and here, but it does require a bit more data processing.
Once VIN is up running, there are a set of zip files that are created in /var/log/vadm/results which are name with the virtual machines MoRef ID. We can quickly view the contents of one of these files (without needing to extract the zip file) by using zcat, here is the command to view one of the zip files: zcat /var/logs/vadm/vm-238.zip
From the screenshots above, we can see it contains the same set of information as displayed in the VIN UI. The information is broken down into several section including high level summary of the VM, individual processes running in the virtual machine, application/services known by VIN as well as a netstat table.
Instead of operating on these files directly, you should make a separate copy of the directory for further processing. Since the file name contains the VM’s MoRef ID instead of the human readable VM display name, I wrote a quick script called extractVINData.sh which creates a copy of data and rename the files to VM display name.
To use the script, you just need to download it and upload it to your VIN appliance (make sure you set the execute permission on the script). Then just run the script and it will automatically copy the directory to /root/vin-results and translate the VM MoRef ID by correlating with the /var/log/vadm/engine.log file.
Here is a screenshot of the script output:
So if you do not mind some parsing, you can easily extract the data VIN is collecting by simply SSHing to the VIN appliance and periodically copying out /var/log/vadm/results directory. From my quick test, this directory is automatically updated as new VMs are brought online and inventoried by VIN.
