it seems like that systemmonitor doesn't provide any "sources" or they aren't added to table in Data Sources table.
Do you see any rows in this table and just the sources name column is empty or even rows is missing?
Have you tried to open the configuration dialog and click to Data Sources tab in plasmoidviewer?
Is there any "error" message in plasmoidviewer console output if you try it?
Is ksysguardd process running?
$ ps ax | grep ksysguardd
You can also try to see if systemmonitor is in output of this command
$ plasmaengineexplorer --list systemmonitor
and if yes do you see any DataSources:
$ plasmaengineexplorer --engine systemmonitor
You can edit ~/.local/share/plasma/plasmoids/com.github.burlog.plasmoid-sysmon/contents/ui/DataSourcesConfig.qml file and add new lines between 73-74 and 74-75 lines how the example shows:
for (var i in systemmonitor.sources) {
print("before filter", i)
if (systemmonitor.sources[i].match(/[^\x{0000}-\x{007F}]/)) continue
print("after filter", i)
After file saving the plasma must be restarted. You can logout and login or you can run
$ killall plasmashell && plasmashell
Thanks for "debuging" :) - Nov 20 2017
