+# VPP interface stats client
+
+This is a source code and a binary of a 'thin client' to collect,
+aggregate and expose VPP interface stats through VPP stats socket API.
+It also provides some information about the installed VPP version.
+
+This can be used by monitoring systems that needs to grab those details
+through a simple executable client with no dependencies.
+
+example use case: where VPP runs in a container that can't expose the socket API to the host level
+
+
+## Prerequisites (for building)
+
+**GoVPP** library (compatible with VPP 18.10)
+vpp, vpp-api, vpp-lib
+
+## Building
+
+```bash
+go get git.fd.io/govpp.git
+go build
+```
+
+## Using (post-build for example on linux 64bit)
+
+```bash
+./bin/vpp_if_stats_linux_amd64
+```
+
+## Output examples
+
+[JSON schema](./response_schema.json)
+[Example](./response_example.json)
