Site Engine Python Scripting - VOSS Enable SFLOW

dreader — Fri, 07 Jun 2024 19:14:02 GMT

I am trying to get used to scripting but have not found anything that does what i want.

I want to send CLI commands to groups but have the %deviceIP built in to the script so it make changes as i need.

For example i was to enable SFLOW so i need to have the local IP in this config.

config terminal
sflow agent-ip %deviceIP
sflow collector 1 address x.x.x.x owner DEV-SiteEngine port 6343 timeout 497
sflow collector 2 address x.x.x.x owner PRD-SiteEngine port 6343 timeout 497
app-telemetry enable

I was also trying to see if there is anyway to do pip install commands to get more features in the scripts.

I've been trying to troubleshoot by adding regex as well but all i ever get is the same export from site engine.

first, in your CLI command bulk is missing the enable command on the leading position.

second, why do you send sFlow data to Site Engine? It should go to the Analytics Engine. And if you add the switch to the Analytics Engine he gets automatically configured with App Telemetry and not only sFlow, which is more advanced.

not sure where you got the inspiration for this Python script. If you are using Python inside Site Engine, the CLI handling is much simpler.

from xmcbase import cli as emc_cli

from xmcbase import emc_vars

###############################################################

def sendConfigCmds(cmds😞

for cmd in cmds:

cli_results = emc_cli.send( cmd )

if cli_results.isSuccess() is False:

print('CLI-ERROR: ' + cli_results.getError())

return False

lines = cli_results.getOutput().splitlines()[1:-1]

if lines:

return lines

else:

return True

###############################################################

## MAIN ##

###############################################################

def main():

cmds = '''

enable

configure

sflow agent-ip <DEVICE_IP>

sflow collector 1 address 172.16.52.46 owner DEV-SiteEngine port 6343 timeout 497

sflow collector 2 address 10.252.52.23 owner adcprdsiteengine01 port 6343 timeout 497

app-telemetry enable

exit

save config

'''

cmds = cmds.replace('<DEVICE_IP>',emc_vars["deviceIP"])

sendConfigCmds( cmds.splitlines() )

###############################################################

main()

Thanks for the help it sounds like what I wanted to get added was redundant it Analytics already does these steps. It seems I was told some bad information regarding switches needed sflow to be configured before adding to the Analytics side.
Regarding the script you sent below. I was trying stuff similar to what you did below but i always get the same failures

javax.script.ScriptException:
*** Script Error ***
null

-> from xmcbase import cli as emc_cli

Is it possible my install is bad and my libraries are gone for some reason?

this is only useful for offline coding using an IDE. XIQ-SE don't need it.

just remove this line => from xmcbase import cli as emc_cli

Thanks for your help on this!
