I recently ran into a peculiar issue after upgrading my vRealize Automation homelab to the new 8.3 release, and the error message displayed in the UI didn't give me a whole lot of information to work with:

I connected to the vRA appliance to try to find the relevant log excerpt, but doing so isn't all that straightforward↗ given the containerized nature of the services. So instead I used the vracli log-bundle command to generate a bundle of all relevant logs, and I then transferred the resulting (2.2GB!) log-bundle.tar to my workstation for further investigation. I expanded the tar and ran tree -P '*.log' to get a quick idea of what I've got to deal with: Ugh. Even if I knew which logs I wanted to look at (and I don't) it would take ages to dig through all of this. There's got to be a better way.
