Splunk Search

Combining "stats dc(x)" with "stats dc(x) by y" in same search

I am having a ton of trouble expressing this query.

Suppose I have 1,000 distinct people, and 25 cities. Over a time period, each person might visit [0...n] cities.

I want a report which shows, for each city, what percentage of my unique people visited that city? Note that in this report, the percentages won't add up to 100%, since any person might visit more than one city in the time period.

This search gives me the # of unique people and returns one row, value of "1000":

eventtype=visit |stats dc(person) | rename dc(person) as "# Unique People"

This search shows # of unique people who visited each city and returns 25 rows:

eventtype=visit |stats dc(person) by city | rename dc(person) as "# Unique People" | sort -"# Unique People"

What I want is, in Search #2, instead of showing a # of people, I want to show the # of people divided by the total returned in Search #1 (which would be a percentage of the total unique people).

Can anyone help? I've played with append, appendcols, join, appendpipe.. I'm lost.

totalPeople ends up empty because the first stats drops the person field, you need to swap things around a bit.

... | eventstats dc(person) as totalPeople | stats dc(person) as uniquePeople values(totalPeople) as totalPeople by city | eval percentage = 100*(uniquePeople/totalPeople)

Thank you. I tried this, but the "totalPeople" column ends up empty. Not sure why.
