Graph actualization after poller frequency change

[rubiohiguey]

Hello,

I wanted to update detail and historical retention of data in graph, created completely new poller (15 seconds daily with 45 days retention) instead of basic 5 minute poller with 2 days retention.

Doing that, I still do not see changes in the "current" graphs and still see my current graphs in 5 minutes slots and traffic details also summed into 5 minute slots.

This is what I did. I created
1. Presets -> Data Profile -> New Profile

I then duplicated (for test purposes) the Data Template Name
2. Interface Traffic -> to Interface Traffic Detailed, with Data Source Profile = New Profile

I then applied the new Data Template to Data Source
3. Management -> Data Sources -> selected data source -> changed Selected Data Template from "Interface - Traffic" to "Interface Traffic - Detailed".
4. Saved

The current data source shows poller with 15 seconds instead of previously used 5 minutes.

When I go to the graph and select let's say the last 30 minutes, it still shows me data details in 5 minute increments instead of 15 second increment.

Do I need to reboot Cacti for the changes to take effect?
Do I need to wait more time?
Do I need to create a completely new graph for me to see these new details?

Thank you.
