EXPERTS! 3Month History accurate up to 1min - RRA's

bryman55 · Post by **bryman55** » Sat May 07, 2005 2:56 pm

I thought I had a handle on this but apparently not. Here are my current settings:

X-Files Factor - 0.5
Steps - 1
Rows - 8035200
Timespan - 86400

Someone tell me if this correct? I'm trying to get 3Months history accurate up to 1 min.

Right now I can see a week just fine but when I change the view to anything larger than a week the graph does not appear. I mean its not like a RED x designating a missing image, nor do I get a graph that is blank without data. All I see is the name of the graph in TEXT and little magnifine glass. The same name as if it were on the PNG image. Please see the attached image for an example what I see.

Anybody Please Help.

Did you create the RRD with all the correct timespans?

Well I created these graphs with these settings:
X-Files Factor - 0.5
Steps - 1
Rows - 8035200
Timespan - 86400

I understand that I can not changes these settings on existing graphs through Cacti but if I create new graphs these settings take effect. And these graphs that are having the problem were created after making the changes.

Does that answer your questions? Are these settings correct if I want to have 3 months of history with 5min accuracy?

Thank You

Your RRA Definition does not look accurate.

Thank you for answering back. Could you suggest an appropriate config for RRA's with 3 Months of history and 5 minute accuracy?

Thanks again.

Be more specific. How many RRA's, and what interval for each.

I noticed I made a mistake about the last request. I would like to be able to store 3 months history up to 1 minute accuracy.

"How many RRA's?"

---> I am confused by this question. Aren't the RRA's the files that get stored per graph. So I assume I want 1 RRA per graph I create.

"what interval for each?"

---> I want to have 1 minute accuracy up to 3 months.

I don't think I am answering your questions correctly. Please explain.

Thank you for your time.

It's like this:

You say you want 5 minute graphs for 3 months. Typically, that's only 1/4 of the answer. What about 30 minute averages, 2 hour averages and 1 day averages?

Oh, I see. Honestly, I could care less what data about that data. So the default is fine. I just want to be able to go in and select a date range from date selector, lets say last month and still see accuracy up to 1 minute intervals.

Understand?

Just to be certain, you don't want to see data from 4 months ago?

Ok I get it. Sorry for being a block head. Yes I would like to see these graphs as well:

Daily (5 Minute Average)
Weekly (30 Minute Average)
Monthly (2 Hour Average)
Yearly (1 Day Average)

But most importantly I want to have 3 months of historical data at 1 minute accuracy.

So your answer would be I want:

Daily (5 Minute Average) - For 3 Months
Weekly (30 Minute Average) - For X Weeks
Monthly (2 Hour Average) - For Y Months
Yearly (1 Day Average) - For Z Years

You provide X, Y, Z

I will correct that (make sure to notice the 1minute average on the Daily graph):

Daily (1 Minute Average) - For 3 Months
Weekly (30 Minute Average) - For 1 Weeks
Monthly (2 Hour Average) - For 1 Months
Yearly (1 Day Average) - For 1 Years

Thanks again.
