I use Release Annotations to tell Azure Application Insights about notable changes. In exchange Application Insights can then tell me, that e.g. my latest deployment is slower than the previous one. I got a lot of value out of this so i wanted to have that for a current deployment. My build agent is Ubuntu-based - and the provided examples in the documentation use PowerShell scripts to annotate the deployment. I could obviously install powershell on my build agent, but it is just a single REST call so another dependency on the build agent was too much for me.
