[mrtg] Re: MBit/s vs. MByte/min

[Corey Smith]

>From my math:

1 MegaByte / Min = x MegaBits / Sec

((1 * 1024 * 1024 * 8) / 60) / (1024 * 1024) = x

which simplifies to:

8 / 60 = 0.1333333

So couldn't you just take the original value multiply it by 8 and divide by
60?

Target[proxy-srvkbinout]:
cacheServerInKb&cacheServerOutKb:shizzle at 172.22.1.1:3401 * 8 / 60

(with all of your original options)

Subject: [mrtg] MBit/s vs. MByte/min



Hi there,

i found a page (http://www.serassio.it/SquidNT/MRTG.htm) about Squid and
MRTG yesterday, implemented it on my site here and it seems to work fine.
But i have some small questions about the configuration. Is it possible to
show the graph's in MBit/s and not MByte/min? Here is my Configuration (as
stated on the page):

LoadMIBS: /var/www/squid-traffic/conf/mib.txt

WorkDir: /var/www/squid-traffic/data
-snip-

# Der Proxy Traffic in b/min
Target[proxy-srvkbinout]:
cacheServerInKb&cacheServerOutKb:shizzle at 172.22.1.1:3401
MaxBytes[proxy-srvkbinout]: 12500000 Title[proxy-srvkbinout]: Cache Server
Traffic In/Out PageTop[proxy-srvkbinout]: <H2>Cache Statistics: Server
traffic volume (In/Out)</H2> <TABLE>
   <TR><TD>System:</TD><TD>squid.local.netz</TD></TR>
   <TR><TD>Maintainer:</TD><TD>Me, Myself and I</TD></TR>
   <TR><TD>Description:</TD><TD>Squid Proxy server</TD></TR>
 </TABLE>
Suppress[proxy-srvkbinout]: y
LegendI[proxy-srvkbinout]:  Traffic In
LegendO[proxy-srvkbinout]:  Traffic Out
Legend1[proxy-srvkbinout]:  Traffic In
Legend2[proxy-srvkbinout]:  Traffic Out
YLegend[proxy-srvkbinout]: per minute
ShortLegend[proxy-srvkbinout]: b/min
kMG[proxy-srvkbinout]: k,M,G,T
kilo[proxy-srvkbinout]: 1024
Options[proxy-srvkbinout]: nopercent, growright, unknaszero, perminute

With that Configuration the graphs are displaying the Traffic in Megabyte
per Minute. But because i want them to be displayed in MegaBit per Second,
i changed the "ShortLegend[proxy-srvkbinout]:" value to "b/s", added
"bits" to "Options[proxy-srvkbinout]:" and removed "perminute". Now the
values are displayed as Mb/s, but the values are way to high. Before the
changes i got something like 52 Megabyte/min. Now the graphs show me
something like 420 MegaBit/s. So the units are displayed right, but the
values are still in "perminute" i guess... I'm a bit confused, so it would
be nice if you could point me to the options to change/add.

Thanks in advance,

Jan
