RE: SNMP protocol in Logic Machine - AlexLV - 14.04.2020
Hi,
As we can now receive bytes in and out 0ver SNMP, how correctly calculate bit/per second from received data?
I found very easy calculation method:
We can calculate the throughput of an interface using this technique:
take a sample of the total bytes-in, wait 60 seconds and take another sample bytes-in total.
TotalByteIn [t = 0s] is total bytes-in after 0 seconds
TotalByteIn [t = 60s] is total bytes-in after 60 second
The average throughput in this time interval is calculated using this formula (the value is Bps)
(TotalByteIn [t = 60s] - TotalByteIn [t = 0s]) / 60 = Throughput
So 60 here - time in seconds, delay between request of SNMP information. Question - how easier store previous data to calculate BPS (I need received value - last one or previous, or other variant - now and next value after 60 seconds).
I tried resident script with time 0, not working but strange - in log showing TX1 and TX2 the same values, but BPS different (in my case I receiving SNMP data every 10 seconds)..
TX1 = grp.getvalue('38/5/22')
log('TX1', TX1)
os.sleep(10)
TX2 = grp.getvalue('38/5/22')
log('TX2', TX2)
BPS = (TX2-TX1)/10
log('BPS', BPS)
How better calculate BPS??
BR,
Alex

Use storage to store previous object value.
See these examples:

You need packages luasnmp and libnetsnmp
you can download it for imx28 here https://dl.openrb.com/lm-17/pkg
for imx6 here https://dl.openrb.com/lm-17-imx6/pkg/
Hi, I have installed these pakkages, but when running the script it says:
Resident script:1: module 'snmp' not found:
no field package.preload['snmp']
no file './snmp'
no file 'Library snmp'
no file 'Library snmp'
no file 'Library snmp.so'

What am I missing?
RE: SNMP protocol in Logic Machine - admin - 09.12.2020
Which firmware are you using? Have you tried the latest packages (https://dl.openrb.com/lm-20-imx6/pkg/)?

hello admin
I have LM Lite + Ext
SW 20200727
when I try to upload the packages I got :
RE: SNMP protocol in Logic Machine - admin - 11.03.2021
You have to install these packages through System config > System > Packages > Add (+) button

hello admin thank you for your response
I upload the packages
I use the walk through SNMP code but I get the following error:
User script:40: attempt to index global 'snmp' (a nil value)
stack traceback:
User script:40: in main chunk
RE: SNMP protocol in Logic Machine - admin - 11.03.2021
Add require('snmp') at the beginning of your script.

Thank you admin for your response
I got a time out in the log what should I check
* arg: 1
* nil
* arg: 2
* string: walk failed: snmp: timeout
RE: SNMP protocol in Logic Machine - admin - 11.03.2021
This means that LM cannot reach the SNMP device on the network. Check that IP address is correct.
RE: SNMP protocol in Logic Machine - Black_Angel666 - 28.10.2021
Good day!
Tell me, is it possible to transfer data from the KNX to the SNMP by means of LM so that another client can monitor the data?

Hello
I added the libnetsnmp and luasnmp packages Please see attached image.
I used the old HL ,V2.7.0
but When I run my script I got the following errors:
Resident script:3: module 'snmp' not found:
no field package.preload['snmp']
no file './snmp'
no file 'Library snmp'

Go to System Config - System - Packages and press + to install.

Hello Daniel
I have the old Schneider electric HomeLynk but I am using FM-V 2.7.0.
I cant find any packages installation option!
RE: SNMP protocol in Logic Machine - Daniel - 19.09.2022
SE does not have this option. Next time buy LM
In upcoming fw snmp libraries will be added. Just wait for a while.

Great.
For Both SE and LM?
RE: SNMP protocol in Logic Machine - admin - 19.09.2022
Yes, for both.
