+### Logging Vector Store Usage
+
+LiteLLM allows you to view your vector store usage in the LiteLLM UI on the `Logs` page.
+
+After completing a request with a vector store, navigate to the `Logs` page on LiteLLM. Here you should be able to see the query sent to the vector store and corresponding response with scores.

+
+You can list all available vector stores using the /vector_store/list endpoint
+
+**Request:**
+```bash showLineNumbers title="List all available vector stores"
+curl -X GET "http://localhost:4000/vector_store/list" \
+  -H "Authorization: Bearer $LITELLM_API_KEY"
+```
+
+**Response:**
+
+The response will be a list of all vector stores that are available to use with LiteLLM.
+
+```json

+  "object": "list",
+  "data": [
+    {

+### Always on for a model
+
+**Use this if you want vector stores to be used by default for a specific model.**
+
+In this config, we add `vector_store_ids` to the claude-3-5-sonnet-with-vector-store model. This means that any request to the claude-3-5-sonnet-with-vector-store model will always use the vector store with the id `T37J8R4WTM` defined in the `vector_store_registry`.
