"TALES expression for Device Name in legend of a component multi-graph report"
To view the discussion, visit: http://community.zenoss.org/message/72694#72694
--------------------------------------------------------------
I have created a multi-graph report with collection items which are OSprocesses (component instances on a device). And with a graph definition with the ps_cpu datapoint.
By default, the legend for that datapoint is: "${here/name | here/id} ${graphPoint/id}", which when I view the report results in the component name (the name of the process) and the datapoint name. For example: "syslog cpu"Â
When I set the graph group to combine all devices on a single graph, they all have the same legend: "syslog cpu"; I can't tell which device that legend entry (color) belongs to.
In zendmd, I can see that a process (+p=dev.os.process()[10+]), does have the "device" method from which I can get the device id (+p.device().id+).
However, I can't seem to nail the syntax to do this in TALES:
${here/device} results in: "<device at {name}>"
but
${here/device/id}, ${here/device().id), ${here/device()/id}, all fail with "tales expression error".

Help!?!?!?
TIA!
