Where can I find 'cacti' application in RHEL ?

Issue

• We are looking to install cacti in our RHEL system, in which channel can I find it?
• If I try to install cacti with 'yum' I got the following message:

[root@server ~]# yum install cacti
Loaded plugins: product-id, refresh-packagekit, subscription-manager
This system is receiving updates from Red Hat Subscription Management.
