Ignoring FS mounts

Hi, I have a new Ubuntu 16.04 server running NET-SNMP version 5.7.3.  I am
seeing a bunch of snmp errors in the syslog whenever my monitoring system
queries the server:

Aug 30 17:25:30 server01 snmpd[3398]: Cannot statfs /run/lxcfs/controllers:
Permission denied

/run/lxcfs/controllers/hugetlb: Permission denied
Aug 30 17:25:30 server01 snmpd[3398]: Cannot statfs
/run/lxcfs/controllers/name=systemd: Permission denied

These errors seem to occur when the hrFSTable is retrieved:

$ snmpwalk -On  -v 2c -c public 350ec-server01 .1.3.6.1.2.1.25.3.8

will trigger the issue for example.  The devices are listed in /proc/mounts:

$ cat /proc/mounts | grep /run/lxc
tmpfs /run/lxcfs/controllers tmpfs rw,relatime,size=100k,mode=700 0 0
freezer /run/lxcfs/controllers/freezer cgroup rw,relatime,freezer 0 0
perf_event /run/lxcfs/controllers/perf_event cgroup rw,relatime,perf_event
0 0
blkio /run/lxcfs/controllers/blkio cgroup rw,relatime,blkio 0 0
memory /run/lxcfs/controllers/memory cgroup rw,relatime,memory 0 0
pids /run/lxcfs/controllers/pids cgroup rw,relatime,pids 0 0
cpuset /run/lxcfs/controllers/cpuset cgroup rw,relatime,cpuset 0 0
cpu,cpuacct /run/lxcfs/controllers/cpu,cpuacct cgroup
rw,relatime,cpu,cpuacct 0 0
devices /run/lxcfs/controllers/devices cgroup rw,relatime,devices 0 0
net_cls,net_prio /run/lxcfs/controllers/net_cls,net_prio cgroup
rw,relatime,net_cls,net_prio 0 0
hugetlb /run/lxcfs/controllers/hugetlb cgroup rw,relatime,hugetlb 0 0
name=systemd /run/lxcfs/controllers/name=systemd cgroup
rw,relatime,xattr,release_agent=/lib/systemd/systemd-cgroups-agent,name=systemd
0 0

and

$ ls -ld /run/lxcfs
drwx------ 3 root root 60 Aug 10 15:09 /run/lxcfs

So it makes sense that snmp can't read that directory.

I tried "ignoredisk /run/lxcfs/*" in the snmpd.conf file but that didn't
help.

The question is, can I configure snmpd to ignore those mounts?  Thanks.  --
Bud
