Try removing and adding the remote CentOS server and check whether you can see the remaining file systems. We have an article on how you can add a remote host (both Ubuntu and CentOS server) on Cacti.

Also, may I know what version of Cacti you are using? This could be a possible bug that might have been addressed in the latest version.

Am having one doubt, i tried to add centos server to monitor in cacti, snmp service are started and rocommunity changed from public all done.

In cacti part in “Associated Data Queries ” the file system read by unix -get mounted partitions.
In this only three filesystem reading other filesystems are not shown.
“only xfs type reading”

In graph also the values are not matching. the values are differs. Kindly help me on this.
