pyControl Toggle Pool Member

Problem this snippet solves:

Summary: A sample pyControl script that toggles a pool member. The main point is the usage of the pycontrol.Utils module, that has some convenience functions for disabling/enabling/status checking of a pool member.

You'll need to change the parameters to reflect your system(s). In this example our BigIP system is 192.168.1.245 with the default username and password info. Our test pool is called pyControl, and the pool member we are toggling is 192.168.43.11 on port 80. Change these to reflect your environment (see syntax, below).

Script

toggle_pool_member.py

How to use this snippet:

The following syntax usage is taken from the IPython interactive shell.

In [10]: import pycontrol.pyControl as pc
In [11]: from pycontrol.Utils import disable_member, enable_member, show_status
In [12]: b = pc.BIGIP(hostname = '192.168.1.245', username = 'admin', password = 'admin', wsdl_files = ['LocalLB.PoolMember'])
In [13]: disable_member(b.LocalLB_PoolMember, 'pyControl', '192.168.43.11:80')
In [15]: enable_member(b.LocalLB_PoolMember, 'pyControl', '192.168.43.11:80')
