If you want to log to file, you could do something like this:

LoadPlugin logfile
<Plugin logfile>
    LogLevel debug
    File "/var/log/collectd.log"
    Timestamp true
    PrintSeverity false

It is recommended that this plugin is loaded before all others (https://collectd.org/wiki/index.php/Plugin:LogFile).

You will want to change LogLevel to 'info' when you are done testing or remove it completely from collectd.conf, as it will produce quite a bit of data.
