Note sure if anyone would know this.... But I presented my team with a Proof of Concept of running SAM to monitor our IRIS Development and Test Clusters. In talking with them we would like additional OS metrics that aren't provided by what is built into SAM. Looking at more OS detail I found node_exporter from Promethus. I added node_exporter to our server that we want to monitor, but then tried to config isc_prometheus.yml to use node_exporter. That did not go well and when I restarted SAM, it would not download the built in metrics to SAM.
