<div dir="ltr"><div><div>I think a frontend would better suit this requirement, rather than depending on collectd alone. You could push your collectd metrics to a time-series database, such as InfluxDB or Graphite. Once there, you can use a frontend like Grafana to display the CPU metrics in aggregate on the same graph or dashboard. Grafana supports both InfluxDB and Graphite, amongst other time-series databases.<br><br></div>Hope that helps.<br><br></div>Giovanni<br></div><br><div class="gmail_quote"><div dir="ltr">On Tue, Jul 19, 2016 at 5:32 AM <<a href="mailto:Matt.Garrett@shell.com">Matt.Garrett@shell.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
