freyes / mongodb_collection_sizes.js
Last active July 23, 2020 14:28 — forked from joeyAghion/mongodb_collection_sizes.js
List mongodb collections in descending order of size. Helpful for finding largest collections. First number is "size," second is "storageSize."
# for juju on xenial
cat << EOF > /tmp/a.js
db = db.getSiblingDB('juju');
var collectionNames = db.getCollectionNames(), stats = [];
collectionNames.forEach(function (n) { stats.push(db[n].stats()); });
stats = stats.sort(function(a, b) { return b['size'] - a['size']; });
for (var c in stats) { print(stats[c]['ns'] + ": " + stats[c]['size'] + " (" + stats[c]['storageSize'] + ")"); }

Getting Started

Configure the lp: prefix in ~/.gitconfig
