 This will only work if you have deployed the necessary script (in the example `/your/script/location/script.sh`) and the necessary sudo rule(s) beforehand. For this you might wanna use techniques described in [Distribute Files](distribute_files) and/or [Custom sudo Rules](sudo).
 
+## Examples 
+
+### Custom Script
+
+A custom telegraf collector can look something like this:
+```bash
+#!/bin/bash
+
+CONNECTED=$(/usr/NX/bin/nxserver --history | awk '$7 == "Connected" {print}' | wc -l)
+DISCONNECTED=$(/usr/NX/bin/nxserver --history | awk '$7 == "Disconnected" {print}' | wc -l)
+FINISHED=$(/usr/NX/bin/nxserver --history | awk '$7 == "Finished" {print}' | wc -l)
+
+# Provide data to telegraf
+echo "nxserver open_sockets=$(lsof -i -n -P | wc -l),connected_sessions=${CONNECTED},disconnected_sessions=${DISCONNECTED},finished_sessions=${FINISHED}"
+```
+
+The first string of the echo command is the name of the series the data is written into. This name can be overwritten in the metric config via `name_override = "nxserver_report"` 
+
+### Custom Config File
+
+A custom config file in /etc/telegraf/telegraf.d could look like this:
+
+```
+[[inputs.exec]]
+  name_override = "remacc_report"
+  timeout = "30s"
+  interval = "5m"
+  data_format = "influx"
+  commands = ["sudo /usr/lib/telegraf/scripts/remacc_report.sh"]
+```
