+## Builtin remote monitoring
+
+On installation, you're asked if you want to enable the remote monitoring for your server or pm2.
+If accepted and if you set the right email, you will receive an email if something hangs (offline).
+
+This monitoring strategy **only do a ping** at a regular interval to pm2.io servers.
+
+If you want to enable it after installation just do :
+
+```bash
+$ pm2 subscribe my@email.com
+# Once the monitoring enabled, you have to restart pm2 :
+$ pm2 dump
+$ pm2 kill
+$ pm2 resurrect
+```
+
+If you want to stop the monitoring do :
+
+```bash
+$ pm2 unsubscribe
+```
