Where does "Target" report get it's data from?

[Evan Richardson]

I tried googling this but didn't get an answer, so hoping someone here knows the answer. I'm using prometheus and grafana to track stats, and I'd like to graph ISCSI bandwidth/usage. Since there's a report that shows activity, it has to come from somewhere, but where? Is it a snmp thing? I doubt it, since snmp isn't enabled by default. If someone could point me to where these stats come from, I'd be greatful!

Thanks

iSCSI is backed by the ctld driver. This might help in your search.

thanks. Looks like ctlstat reveals the metrics, now to see if statsd, node_exporter, or telegraf can grab this data. I wonder if the native "graphite export" option exports this data... time to set up influx and look.
