Not sure why the graph is off

[seefor]

First off I'm new to Cacti and I love this product, great work and great community.
Here is my problem, not sure how to fix it or what to google for.
My SNMPGET results -
SNMPv2-SMI::enterprises.1991.1.1.4.9.1.1.5.46 = Counter32: 13759229



The Counters show 1.3 Million
But the Image shows 2.52 something not sure that.

I choose Bytes In/out Counter64

Thanks in advance for any help

A counter will end up graphing the difference between the first collected value and the next.

So, if the first value collected was 100, and the second value collected was 110, it would graph 10. If the Third value was 115, it would then graph 5.

If it simply graphed the value, you would never see that there was less data between the 2nd and 3rd poll, when compared to the 1st and 2nd, as it would just continue to rise.

thanks Linegod

I looked up the Data Source Type and found the following doc:http://docs.cacti.net/manual:087:3_temp ... a_template

There are four types of data that RRDTool can represent for any given data source: COUNTER, GAUGE, ABSOLUTE, and DERIVE.
A GAUGE is for numbers that are not continuously incrementing, e.g. a temperature.
A COUNTER is for continuously incrementing values that might overflow, e.g. ifInOctets (Traffic).
A DERIVE does not overflow.
The ABSOLUTE type is used for counters that are reset upon reading.

I change it to ABSOLUTE and I'm getting the Value I need now.

Many thanks for the help

Ok so that didn't work out too well

I changed the Data Source Type to GAUGE and it's giving me a better graph:


Here are the numbers:

Thu Oct 7 13:45:01 MDT 2010 14004557
Thu Oct 7 13:50:01 MDT 2010 14006545

How can I get it to show the actual numbers instead of round off the graph?

[Linegod]

In the Graph Template, on the legend GPRINT item, change the GPRINT type to 'Exact Numbers'.

It work well for MAX MIN AVG but broke the Area when I change it:

Code: Select all

Like I said, just change the legend.

I do not see anything under legend with GPRINT

Do you or anyone have the XML files for a Brocade ADX?
