@sed-i should we be adding grafana-agent to ‘tracing/non-juju workloads’ now that we have merged support for it? Also we could be link to How to integrate `cos-lite` with uncharmed applications for more context?

Yes to both questions :slight_smile:

I also think the table is not very readable with discourse’s width limit. Would you like to try splitting this page into sections? From first glance it seems that “Logs”, “Metrics”, … could be the new section titles, but perhaps you discover something different.
