To add a linux host to cacti for monitoring use following steps:
#Configure SNMP server on Linux machine as explained at [[SNMP server configuration for Linux hosts]]
#Login into cacti web interface as admin
#Go to Console -> Devices and choose Add from top right corner
#Enter name in description and address / FQDN in Hostname
#Choose host template as 'Generic SNMP Enabled host'
#Click create
#On the same page after clicking create under 'Associated Graph Templates' section add following templates:
#*ucd/net - CPU Usage
#*ucd/net - Memoery Usage
#*Unix - Load average
#*Unix - Logged in users
#*Unix - ping latency
#*Unix - procesess
#:and then click Save button.
#Click on 'Create Graphs for this host' link at top-right from page resulting after 'save'.
#Choose all graph templates by clicking at top-most check-box on right side
#Choose interesting interfaces by clicking on corresponding check-boxes from below table
#In 'Select a graph type:' drop down at bottom right choose 'In/Out Bytes with Total Bandwitdh'
#Click Create
#Again click Create on next page
#Go to Console Graph Trees
#Click on Add at top right corner
#Type name for tree, preferably same as name written in description while adding device. 
#Click create
#Now click on Console -> 'Graph management'.  Select Host in host drop-down menu so that only graphs related to chosen host appear.
#Select all graphs for this new host using check-box at top right corner
#From Choose an action drop-down menu choose 'Place on a tree (<description>)' to place all graphs for this host on tree created for this host.
#Then click go and then continue on next page.
#Now go to 'Graphs' and in Tree-mode click on name of new host added to see its graphs.

Note that it may take 15-20m before any reasonable current value is shown.  The graphs are really useful only after at least a weeks data is collected to see if any patterns emerge.
