Threshold expressions for node-level metrics doesn't work on non SNMP Collectors

Here's our current config:

capsd-configuration.xml:

</group>

events/programmatic.events.xml:

<event>

<descr>Threshold exceeded for %service% datasource %parm[ds]% on interface %interface%, parms: %parm[all]</descr>

<logmsg dest="logndisplay">Threshold rearmed for %service% datasource %parm[ds]% on interface %interface%, parms: %parm[all]%</logmsg>

</event>

The jrb files are there and the graphs look all pretty, but the thresholds do not trigger.

Please advise.

Thank you,
