This Bash script will loop through all running docker containers on a host and list the disk usage per mount. In case it's breaching the 65%, it will email you.
#!/bin/bash
# get all running docker container names
containers=$(sudo docker ps | awk '{if(NR>1) print $NF}')
host=$(hostname)
# loop through all containers
for container in $containers
do
echo "Container: $container"

> db.setProfilingLevel(1)

Now let it run for a while. It collects the slow queries ( > 100ms) into a capped collections, so queries go in and if it's full, old queries go out, so don't be surprised that it's a moving target...
