Fixing rke2-etcd metrics collection

[mlaguilharre]

This part of the code is not working,
techo "Collecting rke2 etcd metrics"
ETCD_ENDPOINTS=$(grep -oE '\b([0-9]{1,3}.){3}[0-9]{1,3}:2379\b' $TMPDIR/etcd/memberlist | uniq)
for ENDPOINT in ${ETCD_ENDPOINTS}
do
curl -sL --connect-timeout 5 --cacert ${ETCD_CACERT} --key ${ETCD_KEY} --cert ${ETCD_CERT} https://$ENDPOINT/metrics > $TMPDIR/etcd/etcd-metrics-$ENDPOINT.txt
done
The metrics by default are published on line listen-metrics-urls: in file
/var/lib/rancher/rke2/server/db/etcd/config

Thanks @mlaguilharre, the endpoints could be retrieved from the config file.. however, am I correct in saying the for loop would still be necessary to cater for multiple etcd nodes (each endpoint)?

What is not working for you? Happy to simplify this to the config file, but if the memberlist file wasn't populated or the curl is failing it would indicate a larger issue outside of the script.
