## In MongoDB 3.4.16, 3.6.6, 4.0.0 and later, mongod tries to read netstat
## info from /proc/net and store it in its diagnostic system (FTDC).
## See: https://jira.mongodb.org/browse/SERVER-31400
## This means that we need to adjust the policy so that the mongod
## process is allowed to open and read /proc/net/netstat, which
## also typically has symlinks (e.g. /proc/net/snmp).
