The test database of mongodb is always cleared

Question

I don’t know much about mongodb. The test environment uses the test database. After a period of time, the permissions and data tables of the test database are automatically cleared. I don’t know where I can see the operation log? Operating environment os: centos 7.x mongodb: 2.6

1. Set the profile, and then view the database operation log, for example:

设置：
db.setProfilingLevel(2)
db.getProfilingLevel(）

查看：
db.system.profile.find()

2. For important systems, it is recommended to use MongoDB Enterprise Edition. The Enterprise Edition provides complete security audit functions.

For reference.

Love MongoDB, Have fun!

So the online database is very safe It's important!
