+## Configure Telegraf
+
+Telegraf inputs configurations are stored in [telegraf](telegraf) directory. You can test them using the following
+command:
+
+```
+docker run --rm -e "MINER_ADDRESS=${MINER_ADDRESS}" \
+    -v "${PWD}/docker/telegraf.conf:/etc/telegraf/telegraf.conf:ro" -v "${PWD}/telegraf:/etc/telegraf/telegraf.d:ro" \
