I have tried the steps mentioned in,

UnboundLocalError (local variable 'dg_sizefactor' referenced before assignment)

Hi @francisco.fernandes and welcome to the checkmk forum. I’m pretty sure you can fix your issue by updating your checkmk server to a supported and newer version. The version you are using is quite old and not supported anymore. In the meantime a lot of changes have been made to the mk_oracle check plugin as you can see in the werks. Please update your site according to the official documentation from 2.0.0 to 2.1.0 and then 2.2.0. Hope this helps. Regards Norm

but didn’t solve my issue.
Can someone please help me to resolve this issue?

Thank you,
Benson Thomas

Relative easy solution. Copy the “oracle_asm_diskgroup.py” to your “~/local/lib/check_mk/base/plugins/agent_based/” inside your site.
At line 295 where you see some variables filled with values you insert the line.

    dg_sizefactor = 1

Pay attention to the correct indentation and don’t use tabs.
The problem is that dg_sizefactor can be unbound with the local code. The is a “coding style” problem → if - elif without anything if nothing matches.

PS: changed the title to make the problem a little bit clearer
