Splunk EMC VNX add-on not working

[p_gurav]

Hi ,

We are trying to configure Splunk Add-on for EMC VNX for VNX block data. We have distributed environment consisting 6 indexers, 2 search heads and 1 heavy forwarder. We installed emc vnx add-on on heavy forwarder and search heads. We also configured input as :

[vnx_data_loader://sf_vnx_block]
network_addr =
username =
password =
platform = VNX Block
scope = 0
site = SF
index = emc_vnx
disabled = 0

Input is working fine, as we validate with troubleshooting steps.But we are not getting any kind of performance data, also we are getting following exceptions:

2017-06-13 13:22:45,497 ERROR 139829484443392 - Traceback (most recent call last):

Can anybody please help with it? Thanks in advance.

Hi,

Remove Scope from inputs.conf and try loglevel as DEBUG to see performance data in Splunk.

Below inputs works.

[vnx_data_loader://sf_vnx_block]
network_addr = 10.X.X.X
username = vnxuser
password = vnxpassword
platform = VNX Block
index = emc_vnx
loglevel = DEBUG
site = SF
disabled = 0

Thanks,
Sai

We saw something similar with the EMC Isilon app. we had to make an update to correct the scoping of the authhandlers.py python script to just the app.

in line 38 of the authhandlers.py script it was:
entities = entity.getEntities(['admin', 'passwords'], namespace=myapp, owner='nobody', sessionKey=sessionKey)

we changed it to:
entities = entity.getEntities(['admin', 'passwords'], search=myapp, namespace=myapp, owner='nobody', sessionKey=sessionKey)

and now it works.

See if that helps.

Hi jimodonald,

Thanks for your suggestion. I tried editing credential.py and data_loader.py in VNX add-on but it doesn't work. Could you please tell me any another solution.

I tried editing credentials and re installing everything in multiple OS's, I have tried editing many other python scripts but always get the same, I see no one is able to solve this, if you find any solution to this, please let us know! I have tried everything and have lost several hours on this. I am just glad I'm not the only one..
