You would have to enable plugin (uncomment corresponding LoadPlugin in the top of config), uncomment and specify your processes in plugin config (section as shown below)

<Plugin processes>
 	Process "collectd"
 	Process "rrdtool"
 	Process "systemdatascope"
 	Process "sensorfwd"
	Process "sensors.qcom"
</Plugin>

and restart collectd. After running for some time, just regenerate graphs in SystemDataScope settings. Plotting processes stats is supported already (if it is broken, please open an issue).

Just a hint for those that try moitoring processes: it appears the “Process” directive does not pick up those processes (I suspect) whose names appear multiple times in the process list. This affects e.g. GUI apps which are launched through sailfish-qml or invoker.

For those, use ProcessMatch instead.

Example ps output:

nemo      2830  7111  0 08:17 ?        00:00:07 /usr/bin/sailfish-browser
nemo      7111  6486  0 Apr23 ?        00:00:03 /usr/libexec/mapplauncherd/booster-browser --systemd
nemo     14568  6486  0 09:15 ?        00:00:00 invoker -s --type=browser -G /usr/bin/sailfish-browser
nemo     14573  7111 11 09:15 ?        00:00:01 booster [browser]

So this won’t work:

 Process "sailfish-browser"

but this does:

ProcessMatch "sailfish-browser"         "sailfish-browser"

The second parameter is an regular expression to specify the match. Other examples:

 ProcessMatch "android.hw"               "android\.hardware\."
 ProcessMatch "fpd"                      "(sailfish|encsfa)-fpd"
