How to calculate percent from distinct count?

[ra01]

I'm aware of a number of questions on here dealing with percents, including: https://answers.splunk.com/answers/120424/how-to-display-percentage-of-total.html

But I can't figure out how to apply it to my question.

I have browser logs of site sessions, and want to report the % breakdown by device type.

This search gets me a table of device totals (by distinct sessions), but how do i make it a %?

eventtype=pageactions tag=external_traffic session_id=*
| fillnull value=blank devicetype
| stats dc(session_id) as unique_sessions by devicetype
| table devicetype unique_sessions
| addtotals row=f col=t labelfield=devicetype label=total

Actually, ideally I'd like to have two columns (both as %) showing the % of distinct events and the % of all events. That way I can see both what device our visitors are using and if one device is causing more traffic.

I can do that from here (if i could just divide by total)

eventtype=pageactions tag=external_traffic session_id=*
| fillnull value=blank devicetype
| stats dc(session_id) as unique_sessions, count as event_counts by devicetype
| table devicetype unique_sessions event_counts 
| addtotals row=f col=t labelfield=devicetype label=total

How about this? Add up the total using eventstats and then calculate the percentage for each row.

| gentimes start=-500 | eval session_id=random() % 500 | eval device_id = random() % 10 | stats dc(session_id) AS unique_sessions by device_id | eventstats sum(unique_sessions) AS total | eval percent=round((unique_sessions/total)*100,2) | table device_id unique_sessions percent
