Get_SNMP_Data function

Hi,
RTOS has support TCP/IP API function for SNMP agents: Get_SNMP_Data. Does RTOS-LNX have any support for SNMP? I have not found it in the on-line documentation.

Thanks.

Dear Mr. Brezani,

The Get_SNMP_Data() API is unfortunately not implemented in RTOS-LNX.

Since the RTOS-LNX has a Linux system under the hood, the /proc/net/snmp file in the root filesystem can be manually parsed as a workaround. Please consult https://www.beck-ipc.com/api_files/sc145/_access_root_fs.html about how to access files in the root filesystem.

Consult https://www.beck-ipc.com/api_files/sc145/_flavours.html to learn more about the underlying Linux system and how to access it via the shell as well (please read the disclaimer text carefully).

The /proc/net/snmp file will contain something like the following:

Code: Select all

cat /proc/net/snmp

...which you can parse to get the required values.
