Monitoring a Node with Prometheus
Open the port 12798, as it is the default port for prometheus, as from the
When you start the node, it makes Prometheus metrics available at port 12798 (or whatever port you specified in
config.json). You can then setup a monitoring server or monitor your node from your local machine.
#Add Node Exporter to your server
You can get the best out of prometheus if you have both Prometheus on your local machine or monitoring server and Prometheus Node Exporter on your node's server. How to do this depends on your platform and setup, but you can find documentation:
#Setup Prometheus in your local machine or monitoring server
Prometheus needs to be configured to monitor your Cardano Node. A minimalistic configuration file doing this could look like this:
You have to replace
a.b.c.d with the public IP-address of your Cardano Node server, which you can find on the dashboard under IPv4 Public IP.
#Start Prometheus node exporter on your node's server, for example:
On your browser open
a.b.c.d:9090, pick one or more interesting metrics to graph and enjoy!
Security configurations you should perform on your monitoring server are out of scope for this tutorial.
