Hello, After implementing “external source” feature, i tried it out with my RabbitMQ instance. I added it via “pmm-admin add external --service-name=“RabbitMQ Data” --listen-port=5672” and it added. Now how can i see it at Grafana? I could not find any doc about it, can you help please? ---

Hi Ghan, You may check collected metrics in Prometheus and create your own dashboards. e.g. [https://172.17.0.2/prometheus/graph](https://172.17.0.2/prometheus/graph) ![](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/1X/e04528a030c47325fc522700a257d8ee710e74b5.png) ---

Is there any way to listen systemd at linux (like old pmm lunix:metrics)? For example, it simple, i need to listen web ports (nginx). How can i do that? ![](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/1X/5ef20012c2fa3ef8d7b4b1ee10c6139c660e4b17.jpeg "Image: /uploads/percona1/original/1X/5ef20012c2fa3ef8d7b4b1ee10c6139c660e4b17.jpeg") ---

I think informations are mixed. **What i need** : I need to monitor a service running inside linux. (It can be possible with tracking pid file or listening ports) Like postfix, nginx, ssh etc. **What external source feature provide** : I have to install external “exporter” such as nginx\_exporter or rabbitmq\_exporter of prometheus. If i am right, _how can i achive my goal?_ ---

Hi Ghan, You can make it by using textfile-collector feature of the node\_exporter. So you should create a bash script that would tracking pid files or listening ports. Here is a [step-by-step instruction](https://www.percona.com/blog/2018/08/28/extend-metrics-for-percona-monitoring-and-management-without-modifying-code/ "Link: https://www.percona.com/blog/2018/08/28/extend-metrics-for-percona-monitoring-and-management-without-modifying-code/") for using this feature. It’s written for PMM1 so please use a different folder for placing files with metrics. Here are list of folder for PMM2: /usr/local/percona/pmm2/collectors/textfile-collector/high-resolution /usr/local/percona/pmm2/collectors/textfile-collector/low-resolution /usr/local/percona/pmm2/collectors/textfile-collector/medium-resolution ---

Thx adivinho, i found another solution: I created a another node\_exporter service with --collector.systemd option. Then i created external source from pmm-admin on its port. Im able to get status each service of server. (Prometheus query : node\_systemd\_unit\_state{name=“nginx.service”,state=“active”})  Thanks!
