Troubleshooting

Using the Python Debugger

One of the most powerful tools when debugging the Python portions of a ZenPack is the Python debugger (pdb). With pdb you can set breakpoints in your code. When the breakpoints are hit, you get a (pdb) prompt that has full access to examine the stack and any local or global variables.

To set a breakpoint in your code you add the following line.

import pdb; pdb.set_trace()

As with any code change, you must restart the Zenoss process that executes the code in question.
