Unit conversion - wrong graph

[hacknisty]

Hi all,

I've got a small problem monitoring windows 2008 R2 Server.

I'm using the "\Memory\Available MBytes" performance counter to monitor available RAM.

This performance counter reports available memory in MBytes. And i have thousands of MBytes (let's say 2150 MBytes) memory available.

Here is a trace of what this performance counter report :

"03/03/2015 09:44:32.051","2152.000000"
"03/03/2015 09:44:33.052","2152.000000"
"03/03/2015 09:44:34.053","2152.000000"
"03/03/2015 09:44:35.054","2152.000000"
"03/03/2015 09:44:36.055","2152.000000"
"03/03/2015 09:44:37.057","2152.000000"
"03/03/2015 09:44:38.060","2152.000000"
"03/03/2015 09:44:39.061","2152.000000"
"03/03/2015 09:44:40.062","2152.000000"
"03/03/2015 09:44:41.063","2152.000000"
"03/03/2015 09:44:42.064","2152.000000"

and here is my graph conf :

                    </item>
                </graph_item>
            </graph_items>
        </graph>

But it seems that zabbix convert this value in K (because it's thousands) and obviously my graph are wrong. (as you can see in the attached image value is KMBytes instead of GBytes)

Do you have any clue on how i get around this ?

Hello and welcome to Zabbix forums!

You should be gathering data with the base units which is Bytes.

perf_counter["\Memory\Available Bytes"]

And then in item settings specify Units: B which will then convert your data automatically to KB, MB or GB.

Hope this helps!

[SOLVED] Unit conversion - wrong graph

It works great.
Thanks a lot for that tip. I should always retrieve the base unit.

En el caso de SQL Server, el typeperf, me obliga a que lea en KB
SQLServeratabases(tempdb)\Data File(s) Size (KB) Como podria solucionarlo?
