Summary0015137: SELinux is preventing /usr/bin/mongod from 'read' accesses on the file snmp.
DescriptionDescription of problem:
> installed mongodb 3.6
> semanage port -a -t mongod_port_t -p tcp 27017
> added new service in firewalld and reloaded
> systemctl enable mongod.service
> systemctl start mongod.service

ended up in selinux alert .

/usr/bin/mongod attempted to read file [ snmp , netstat]
SELinux is preventing /usr/bin/mongod from 'read' accesses on the file snmp.

***** Plugin catchall (100. confidence) suggests **************************

If you believe that mongod should be allowed read access on the snmp file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'ftdc' --raw | audit2allow -M my-ftdc
# semodule -i my-ftdc.pp

Another user experienced a similar problem:

Install CentOS 7.
Install the latest MongoDB (I got 4.0.3) :
yum install \ \ \ \

Start the mongodb server
sudo systemctl start mongod

Connect to the Mongo DB and run some query
echo '
  use testdb
' | mongo

You should see some FTDC entries in mongod.log:
sudo grep FTDC /var/log/mongodb/mongod.log

You should also see entries in the audit logs:
sudo ausearch -c 'ftdc' --raw
