Hello,
I have a silly problem. I can't get stats latest(_time) to return a value. It's a basic search--just trying to find the last time each host reported in.
index=foo | stats latest(_time) by host
earliest(_time) seems to work, and so do the first and last functions, but latest just gives me a blank entry. What's going on? If it matters, this is perfmon data and I think it's pretty clean. It's not just the _time field either; no field I pass to latest is giving me a result.

In the mean time, use;
|metadata type=hosts index=foo | eval Last_seen = strftime(lastTime, "%Y-%m-%d %H:%M:%S")| fields + host Last_seen
EDIT: Much faster than what I just posted. Deleted that. Sorry.
EDIT AGAIN: cut-n-paste silliness. Corrected now.

The workaround is for this particular question: "At what time did we receive the last message for each host?"
This can be answered by querying the metdata instead of the events themselves. Pretty much the same by which Splunk instantly 'knows' and presents the times for the oldest/newest event in the landing page for the Search app and for each index in Manager -> Indexes.
The lastTime is returned (in epoch format) by the |metadata search command. To present it in a nicer fashion it is then eval:ed with strftime.
Have you tried it?

I don't understand the workaround. Where are we supposed to get lastTime? isn't that the whole point with using the latest function? I am using version 5.0.1 and still experiencing this issue.

This most definitely seems to be a bug. Others have reported the same problem, so you're not alone. Have a look at http://splunk-base.splunk.com/answers/42084/latest-function-in-stats-not-working-without-earliest

Yep, that's exactly it. Guess I should search more carefully before I post. Thanks!
