[mrtg] One MRTG graph, two datasources

[Sean Cheesman]

I would also snmpget them as the humidity may be returned in a different format than you think (ie 723=72.3%).  With your MaxBytes set to 100, you may be unintentionally dropping your humidity traffic.

Are you able to do an snmpget on both OID's and get values? That would be my
first guess, that the second OID is not returning a value, or just 0.

Hello guys,

I'm trying to graph both temperature and humidity to the same graph by using
MRTG. However, when I do it as advised in your documentation, I only see the
temperature (first OID in the "& chain") and not the second one (which is
humidity)

Here is my config for the particular probe:

Target[probe1]:1.3.6.1.4.1.3854.1.2.2.1.16.1.3.0&1.3.6.1.4.1.3854.1.2.2.1.17
.1.3.0:public at sensorprobe.domain.com
Title[probe1]: Soyle Generell Temp
Options[probe1]: nopercent,gauge,noinfo,nolegend,noo,growright
PageTop[probe1]: <H1>Probe 1</H1>
Ylegend[probe1]: Temperature in Celsius
LegendI[probe1]: Temperature:
ShortLegend[probe1]: 'C
MaxBytes[probe1]: 100
XSize[probe1]: 500
YSize[probe1]: 175
YTics[probe1]: 5
#Colours[probe1]: BLUE#61A7E2, BLUE#6188E2, BLUE#6268E2, BLUE#7B61E2

Why am I only seeing the first OID (1.3.6.1.4.1.3854.1.2.2.1.16.1.3.0) and
not the second one (1.3.6.1.4.1.3854.1.2.2.1.17.1.3.0)?


Preferably I want one green filled graph for the temperature, and then a
solid blue thin line for the humidity. How can I accomplish this? I've tried
looking up some historical threads about this, but it didn't really help me
much.

Any ideas?

Best regards,

Vidar S
