promising to release (I talked about it at the last SS user group meeting at Argonne) that allows use of Grafana with the zimon data. This is working well for us.<o:p></o:p></span></p>

<p class="MsoNormal">"<span style="font-size:10.5pt;font-family:Arial;color:#333333;background:whitesmoke">mmpmon does not currently aggregate cluster-wide data. As of SS 4.1.x you can look at "mmperfmon query" as well, but it also primarily only provides node
specific data. The tools are built to script performance data but there aren't any current scripts available for you to use within SS (except for what might be on the SS wiki page). It would likely be something you guys would need to build, that's what other
clients have done.</span>"<o:p></o:p></p>
