Network Performance graph - what's this? RN316
RN316 6.9.5
What unit is 'm', I'm presuming 'M' as per the scale is megabytes, maybe megabits??
Also is lower 'k' different to what is normally (industry) 'K' meaning kilobytes?

Re: Network Performance graph - what's this? RN316
While I'm on the topic of graphs...
Can you confirm 'm' in this graph is million?
Should and/or is the graph scale in 'm', ie in thr right below ~100million operations?
Why are there zero operation/sec every other minute?
What is an 'operation', as in IOPS? I/O's to arrays, or sum of disks??

Re: Network Performance graph - what's this? RN316
You are incorrect regarding the industry standard being upper case "K". The proper (and used here) SI abreviation for "kilo" is a lower-case "k". For "mega" it is an upper case "M" since "m" is milli.. The scale is clearly labeled "Bytes per second". So "k" is kilobytes per second and "M" is megabytes per second. There is an odd, inconsistent use of "m" vs. "M", though.

Re: Network Performance graph - what's this? RN316
I'm taking about the Information Technology 'industry'.
In my 30+ years K was 1024 bytes, until marketing got involved. (WDC settled that case BTW)
Historically (& here) the terms varied.
'k' is predominant in regards to bits, kbps, whereas as KB(1,2,3) is used for kilobytes, KBps is the usual term rather than kBps although this is also used.
e.g. 56K modem.
'Industry':
Microsoft, e.g. Windows file properties, size "1.63 KB (1,674 bytes)"
Linux, e.g. ls -lh bin/bash "-rwxr-xr-x 1 root root 1006K Nov 6 2016 bin/bash"
Netgear, e.g. Frontview share listing "482.6 KB"
IBM, e.g z/OS
But you know what thay say is the best thing about computing standards?
There are so many to choose from, and
if you don't like any you can create your own.

Have you set the language to somethng other than English? There have been some reports of odd characters there with some languages. Some do use "u" for "µ", but I'm pretty sure that's not it.

Re: Network Performance graph - what's this? RN316
Nope, language is set to english.
Tho I did wonder if it was u for mu for micro, as it was on the Average, avg=total/samples, for an idle NAS total is tiny, samples is larger.

RRDTOOL Doco mentions:
"%s - place this after %le, %lf or %lg. This will be replaced by the appropriate SI magnitude unit and the value will be scaled accordingly (123456 -> 123.456 k)"
So probably mu.
