Monitoring a LiteLLM Proxy - What the Admin UI Covers, and What Only Grafana and Langfuse Show
I attached Prometheus, Grafana and Langfuse to a LiteLLM proxy and ran the same mock traffic through all of them for 14 minutes. The built-in Admin UI goes as far as who spent how much; time series and alerts need Grafana, and request bodies, sessions, traces and scores need Langfuse. Here is where the Admin UI is enough and the order to add the rest.
