MRTG collect and graph datas

[andyproxis]

Hello !

I would like to graph datas like VCC, temperature INP3 voltage, INP5 current. Maybe someone already has working mrtg.cfg file to share ?

Also Tomek, i read you are preparing additional board for current till 12A, when can it be ready ? Im quite interested in such stuff, cause i wanna use lan controller within my solar power system to check values (voltage and current) from solar panels.

Thanks for response,
Andy

PS: I understand and speak polish without problem, so you can answer me in polish. Just I cant write. Sorry...

MRTG nie testowałem, może ktoś inny sie podzieli plikiem konfiguracyjym.
Możesz spróbowac Lstat http://tinycontrol.ats.pl/forum/viewtopi...f=5&t=2592

Co do pomiaru prądu do 12.5A, to mam już w testach taką standardową płytkę z acs711, więc myślę, że tak za około tydzień lub dwa powinien byc soft do jego obsługi. Napisz jeszcze jakie masz maksymlane napięcia na tym solarze?

Hi
The simplest way to graph data provided by Lan Kontroler is to use SNMP. MRTG is able to utilize SNMP to get data and graph them. This is easy.
Eg. here you can find how to use MRTG to graph SNMP data, base on OID: http://www.enterastream.com/whitepapers/...-cap9.html
Lan Kntroler OID's MIB is located in last pages of manual.

Thanks, I will try. If someone has working mrtg.cfg, it can save me a lot of time.

Voltage 0V - 36V (max i measured).

Hello,

UPDATE for newer versions:

1, use

Kod:

iso.3.6.1.4.1.17095.5.1.0&iso.3.6.1.4.1.17095.5.1.0:public@X.X.X.X:::::2

instead of enterprise.3.6.1.4.1.17095.5.1.0&enterprises.3.6.1.4.1.17095.5.1.0:public@X.X.X.X:::::2
2. because the temperature is expressed as 320 for 32.0 'C you must divide it by a factor of 10

Kod:

Factor[temp_1]: 0.1
Xsize[temp_1]: 600
Ysize[temp_1]: 200
Ytics[temp_1]: 5
YTicsFactor[temp_1]: 0.1

BUT my second grapth seems not to read the sensor:
