Hello Fellow Thwackians,
After receiving help from Solarwinds Tech Support (which was very helpful this go around), I have managed to accomplish the difficult task of finding the OID line for different monitors from NTI!
NTI came out with the E-MINI which has inherent flaws with its network processor which locks the device up and causes no connection. the E-MINI-LXO are the replacement for these devices and correct the previous issue. On-top of being improved, these devices use the same OID for temp or humidity as opposed to the previous generation which the OID with the sensor varied.
I will start with the newer E-MINI-LXO and the OID and short step process for finding the line for temp and humidity as well as the conversion factors.
The simple way to find the LXO OID for the temp/humidity is to use the Solarwinds SNMPwalk and download the text file.
The new LXOs will have around 319 lines of OID and are already prefixed with 1. all you need to do is take the . from the beginning and exclude it.
ex: .1.3.6.1.2.1.2.2.1.7.1
1.3.6.1.2.1.2.2.1.7.1
removing the . from the start of the line is the correct flow of the OID.
The temperature OID on our company's E-MINI-LXO is:
1.3.6.1.4.1.3699.1.1.8.1.5.1.1.7.1
I found this by performing an SNMPwalk and comparing the current LXO temperature through the GUI and cross referencing using the ctrl+f in notepad and looking for the numerical representation without the decimal.
ex: if my current temp reading on the LXO is 66.5 degrees Fahrenheit then removing the decimal gives me 665. Using the FIND function I immediately found the line:
.1.3.6.1.4.1.3699.1.1.3.1.2.1.0 = INTEGER: 665
After I have found the line, I then remove the . and create a universal device poller in my NPM server. I use the following OID to identify my temperature sensor:
-remove the dot!!! -->(.) 1.3.6.1.4.1.3699.1.1.3.1.2.1.0
In the advanced Options, I used the following settings to allow my data to be polled correctly:
MIB Value Type: Raw Value
Format: Enumeration
SNMP Get Type: GET
Polling Type: Node
Polling Inerval: <BLANK>
The humidity sensor for E-MINI-LXOs are as follows for the device we have:
1.3.6.1.4.1.3699.1.1.8.1.5.1.1.7.2
Our company wants historical data and of course, enabled status.
After clicking next you can test it on a NTI device and verify that your data is polled. Then after you select it to show on the website on the Node summary as a gauge.
The next step is to convert the raw value into a proper number. Essentially you are going from proper form to raw then back to proper.
Click on the poller you've just created then at the top of the poller manager, click Transform Results.
The prompt that comes up allows you to define what the names is and what it does, I left the choices default and went to the next screen.
In the next screen you are presented with a formula and you will need to understand basic math to place a decimal in the correct spot in order for the result to display correctly. The following are our company's setting for the temperature reading of the E-MINI-LXO:
Formula: {EnviromuxLXOTemperature}/10
Where as {EnviromuxLXOTemperature} is the poller we created to retrieve the OID with the value of the temperature in a raw state.
Next we place the sign that represents division, this is shown as /
Since this integer is only shown as 3 digits, we will divide by 10 in order for our decimal to be placed in the correct spot.
665/10= 66.5
Once this formula is put in place you can test it on your NTI device and verify.
NOTE: The LXO devices appear to have been unified with the OIDs for the temperature and humidity combo sensor. This is proven with our 2 LXO devices that are in production.
The E-MINI older generation devices appear to have different OIDs between the Temp and Humidity with the 4 our company has. I have 2 in production that are working and 2 that are not. the 2 that are working I had to create 4 pollers, 1 temp and 1 humidity for one E-MINI and duplicate the same for the other E-MINI (which has a different OID for temp and humidity). Through this process I also had to create Transform Results for each of the E-MINI and create 1 temperature Transform Results for the LXO. The LXO humidity needs no result transformation.
Please feel free to email me for any updates or information on this subject. I am in the works of creating a walk through for the older models which reflect the same steps as the LXO but require conversion for the temp and the humidity.
