Subject: Updated to use OS metrics from default scrape job
X-Git-Tag: v2.0~15^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=refs%2Fpull%2F196%2Fhead;p=cephmetrics.git

Updated to use OS metrics from default scrape job

All node_exporter scrapes are now done under the
same job (called node) so the dashboard now uses
an updated template query to identify the correct
host to pull out the OS metrics by iscsi gateway
