How do you identify InnoDB table corruption?
Morgan gives a hint in his comment that InnoDB is constantly checking for corrupted pages by doing checksums on the pages it reads. If InnoDB finds a checksum mismatch, it will crash stop the server.

If you want to speed that process up (instead of waiting for InnoDB to read the corrupted page), you can use innochecksum:


  Because checksum mismatches will cause InnoDB to deliberately shut down a running server, it can be preferable to use this tool rather than waiting for a server in production usage to encounter the damaged pages.


An interesting caveat:


  innochecksum cannot be used on tablespace files that the server already has open. For such files, you should use CHECK TABLE to check tables within the tablespace.


So yes, for  an online table CHECK TABLE is probably the tool (or as pointed out in another answer mysqlcheck if you want to do more than a single database at a time.)

If you can shut down your database you can force it the checksums using innochecksum

Anecdotal:
On a innodb tablespace of 29GB  (with innodb_file_per_table=1), this script took about 2 Minutes

#!/bin/bash
for i in $(ls /var/lib/mysql/*/*.ibd)
do
  innochecksum -v $i
done


As a bonus, though, since you are running Percona, they implemented a new method for fast innodb checksum. I've never used it, but it might speed up the process.
