Hi @sphiwee the empty spaces meaning no matches, .. did the splunk search matched on all logs? all the logs are in the same format ? 

please update the search query last portion...  "| table memoryUsed directory _raw"... so for the empty space, corresponding log lines can be seen.. copy paste those lines please...

thanks and best regards,
Sekar
