There are no items in your poller cache. Make sure you have at least one data source created. If you do, go to 'Utilities', and select 'Clear Poller Cache'.

export: running graph export

Please help me out

In the Utilities I have user administration and logout user. I can't see Poller Cache. I am running cacti 0.8.2

Any suggestions how to fix this problem
