Polling and caching realtime instead of 5 minute average?

[omergencay]

Hello everyone,
We are using Cacti 0.8.8a right now. It is polling the traffic information in 5 min. intervals. But we wanna see the max and min. values "IN" that 5 minute interval. Cacti is showing the 5 min. average of the traffic. If we set the polling interval to 10-20 sec. vs. the server can not handle this much operation. For example Solarwinds Orion is presenting both 5 min. averages and max min. values in that interval but Cacti is not.

Is that possible? Thank you.

You can get down to 1 minute polling interval which would then show you the min/max data as well as the average.

I assume in 1 minute setting. System shows 1 minute average AND min. max values too?

It does. Unless you zoom in and only view at a 1 minute interval, where MIN = MAX = AVERAGE.

If you look at 5 minutes, you will see the average over that 5 minutes, as well as the MIN and a MAX value, which could be from any of the 5 polls within that 5 minute interval

Thank you for your aid but I realize a new problem. When i choose the Settings/Poller/Cron Interval to 1 minutes. The graphs are gone. They only created in 5 minutes mode. And in 5 minutes mode my graphs are created with average value as earlier.

What are the Poller interval, cron interval and Default RRA values in graph settings exactly mean?

Did you change the cron job as well ??
