Openxenmanager, unable to view performance graphs

deleted77 · 11-02-2014, 11:46 AM

Hi,
I installed openxenmanager on Debian Wheezy. I can connect to the xen server but I see nothing in the Performance tab. There are no Performance Graphs.

In the console I can see the following error:

Code:

Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 552, in __bootstrap_inner
    self.run()
  File "/usr/lib/python2.7/threading.py", line 505, in run
    self.__target(*self.__args, **self.__kwargs)
  File "/usr/share/openxenmanager/oxcSERVER.py", line 708, in update_performance
    if ds[name[:3]].count([name, desc]) == 0:
UnboundLocalError: local variable 'name' referenced before assignment

rrdtool is installed.

Hi,
I found a sollution. I had to modify the file: /usr/share/openxenmanager/oxcSERVER.py .
The problem is with the lines 708, 709, 710 and 711. For testing you can just comment lines 708, 709, 710 and 711. If you comment those lines of code, you will be able to see the graphics without any errors, but I don't know if are there any adverse effects with the lines missing (commented).

The propper way of solving the problem without any adverse effects is to keep those lines and just ident the block of code starting with

Quote:

if ds[name[:3]].count([name, desc]) == 0:......

inside the block starting with

Quote:

if data_source['enabled']: ....
