+title: Setting up monitoring on local cluster
+---
+This page describes how to set up a monitoring site, [like this one](http://eth-netstats.herokuapp.com/), for your private network. It builds upon [this wiki article](Setting-up-private-network-or-local-cluster) and assumes you've created a local cluster using [this script (gethcluster.sh)](https://github.com/ethersphere/eth-utils).
+
+The monitoring system consists of two components:
+
+1. **eth-netstats** - the monitoring site which lists the nodes.
+2. **eth-net-intelligence-api** - these are processes that communicate with the ethereum client using RPC and push the data to the monitoring site via websockets.
+
+#Monitoring site
+Clone the repo and install dependencies:
+
+    git clone https://github.com/cubedro/eth-netstats
+    cd eth-netstats
+    npm install
+
+Then choose a secret and start the app:
+
+    WS_SECRET=<chosen_secret> npm start
+
+You can now access the (empty) monitoring site at `http://localhost:3000`.
+
+You can also choose a different port:
+    
+    PORT=<chosen_port> WS_SECRET=<chosen_secret> npm start
+
+#Client-side information relays
+These processes will relay the information from each of your cluster nodes to the monitoring site using websockets.
+
+Clone the repo, install dependencies and make sure you have pm2 installed:
+
+    git clone https://github.com/cubedro/eth-net-intelligence-api
+    cd eth-net-intelligence-api
+    npm install
+    sudo npm install -g pm2
+
+Now, use [this script (netstatconf.sh)](https://github.com/ethersphere/eth-utils) to create an `app.json` suitable for pm2.
+
+Usage:
+
+    bash netstatconf.sh <number_of_clusters> <name_prefix> <ws_server> <ws_secret>
+
+- `number_of_clusters` is the number of nodes in the cluster.
+- `name_prefix` is a prefix for the node names as will appear in the listing.
+- `ws_server` is the eth-netstats server. Make sure you write the full URL, for example: http://localhost:3000.
+- `ws_secret` is the eth-netstats secret.
+
+For example:
+
+    bash netstatconf.sh 5 mynode http://localhost:3000 big-secret > app.json
+
+Run the script and copy the resulting `app.json` into the `eth-net-intelligence-api` directory. Afterwards, `cd` into `eth-net-intelligence-api` and run the relays using `pm2 start app.json`. To stop the relays, you can use `pm2 delete app.json`.
+
+**NOTE**: The script assumes the nodes have RPC ports 8101, 8102, ... . If that's not the case, edit app.json and change it accordingly for each peer.
+
+At this point, open `http://localhost:3000` and your monitoring site should monitor all your nodes!
