After granting access to rpc: SELinux is preventing /usr/sbin/collectd from read access on the file nfsd. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that collectd should be allowed read access on the nfsd file by default. Then you should report this as a bug. You can generate a local policy module to allow this access.
