Hi,

Thank you for your help.
I have 2 Cacti servers, 1 Cacti server is in production, and 1 Cacti server for testing so this will apply to new rrd files.

Quote:
Daily (5 Minute Average)
Weekly (5 Minute Average)
Monthly (5 Minute Average)
Is the Yearly (1 day Average) or Yearly(5 Minute Average) ?

I will change RRA per your instruction, let it run for few days and I will let you know.
Attached is the graph from last month, if you look at the graph Daily (5 Minute Average), you can see one of the day in that month the network is down from 9 pm to 6 am, do you know how to calculating the % uptime when you look at the graph.
Please help.
Thanks...David

Yearly: for the first month, resolution will be 5 min. For the second month, resolution will be 2 hours (the 3rd rra holds consolidated 2h averages for 775 data points, so it covers appr. 2 months). All other data will be 1d averages.

Hello,

I was reading alot on this subject and I am not really sure of the solution maybe you can give me a clear final answer, in order to achieve a Monthly 95th percentile 5 minute average graph is it enough to resize(for existing rrd's) or modify the RRA for 5 minute definition to read Daily (5 Minute Average)] 1 - 11000 - 86400 ?

Thank You !

Hello Guys,

I am new to cacti forums. This is also my first communication with you guys. It really is very helpful that all the gurus, developers and users are exchanging knowledge in this forums.

I have read
Gandalf
's post on making 1 minute polling with 5 minutes average. I haven't really done it, but it seems a lot has worked by that way. I have a little change on the setting, i am trying to make 1 minute polling with 15 minutes average. I tried making 1 minute, with step 15 so that 15 minutes would be consided. But there's a 2 problem on that, first is that i dont see any inbound traffic(absolutely nothing), second is that my outbound has maximum of about 800Mbps, no higher value get drawn on the graph.

Could anyone help me with this?

This would be very much appreciated!

Thanks,
Munkhbat
