I enjoy having a copy of the history in slack.
What I do is have all jenkins deploys send a record to the #deploys channel (Service X, version Q deployed by person Y completed successfully in Z minutes), which comes for free with a tiny jenkins plugin.
However one of the unicorns I worked at deleted all slack messages after 3 months for legal reasons, as one example. Also, slack has periodic outages.
I think a lot of people underutilize jenkins, but once you're handy with it (and get over its god-awful ui) you never go back.
We liked it because the chat history you see is essentially a deploy history, no need to login into some other website to check some obscure logs page to see who did what. We did end up having to debug the service that processed the chat messages maybe once, but never ran into an issue when we had to deploy a hotfix.
