SNMP for CRIO 9068 LinuX RT

[ttesfay]

Hello,

Does the CRIO 9068 LRT come with SNMP agent already installed? If not, is it possible to compile the Net-SNMP source code using the NI Eclipse edition and install it.

Thanks,

T

ttesfay,

The cRIO 9068 does not include a SNMP agent as-is, and you could certainly build one through Eclipse, but you have an easier option: enable the on-controller package manager and install community software through it.

Read over the FAQ for some background information on the package manager then try a command along the lines of "opkg list | grep -i snmp" to get an idea of the packages that you have available to you

Unfortunitely, after taking a quick look, there doesn't appear to be any snmp clients available from the angstrom package repo.

Could you perhaps implement one in python or perl?

Additionally, the BeagleBone eco-system is very similar to that of the version of Linux on the cRIO.  You may have some success following this tutorial:

Good luck!

...

You sure?

admin@Nick-9068:~# opkg list | grep -i snmp

cups-backend-snmp - 1.4.6-r0.9 - cups backend for snmp

Make sure to enable the repos and run opkg update.

Whelp, looks like someone formatted my cRIO-9068 and reset the /etc/opkg/angstrom-base-feed.conf file ... my appologies.

Looks like net-snmp-dev may be a good stating point for calling snmp functions.  If you can getaway with the overhead, you may want to look into using System Exec.vi and the snmp client from the CLI.

To add to tduffy's response, certainly if you can deal with the overhead of calling the SNMP utilities through Exec rather than a CLN interface, it is far simpler. I have some wrappers I wrote years ago that work with the version of the SNMP utilities that Cygwin shipped at the time. I would guess that they would continue to work here since the command line paramaters have likely not changed.

Of course you said mentioned you wanted to be an agent and not a manager, so these VIs might not help you since they just wrap the typical snmpget/set/walk utilities, but I'll post in case they are useful:

BlueCheese,

These are great!  Thank you so much for posting!

ttesfay,

If you end up using these, and they work as-is, could you post back to let us know?

Which parameters can I monitor?

I have installed snmp-agent from all snmp packet from repo, I wish read informations about cpu and memory, but I can see only stupid OID:

Can I resolve it?
