Hi!

Is there a simple way to get sum of all indexes of all databases in mongo?

Thank you.

Write a script iterating over all database and sum up
db.stats()['indexSize'].

not so simple :)

var sum = 0; db.getMongo().getDBs()["databases"].forEach(function(x) { sum += db.getMongo().getDB(x.name).stats().indexSize }); print(sum)
