pmp-check-mongo check_cannary_test throws FAILED: 'float' object has no attribute 'total_seconds'

[b2cc]

Hi!

I get an error using the pmp-check-mongo when I try to use the check_cannary_test

• Error Message

/usr/lib64/nagios/plugins/pmp-check-mongo.py -H localhost -P 27017 -u <user> -p <password> -A check_cannary_test -W 3 -C 5 -d test1 -c test -q "db.test.find()"

CRITICAL - Collection test1.test  query FAILED: 'float' object has no attribute 'total_seconds'

User and password are fine, I can login and other check method work as well - only the cannary test fails.

The Database and collection exists:

PRIMARY> db.test
PRIMARY> db.test.find()
{ "_id" : ObjectId("5abce2eda51d76dba2666695"), "name" : "test1" }
