Get list of monitors through SDK

I am trying to mimic the Health Monitors section from a pool properties page from the BigIP gui. I need to get a list of all monitors so I can construct a select field in a web page. I have tried several versions of:

 

for monitor in mgmt.tm.ltm.monitor.get_collection():
        for item in monitor.get_collection():
                pprint(item)

 

But, this obviously doesn't work. If I could get a list of the monitor types I could iterate through them, but I can't seem to get a list of types either.

    'monitor' is another collection with the various monitor types collections inside. You can access to the monitor type collections. Example for TCP:

     

    tcps_monitors = mgmt.tm.ltm.monitor.tcps.get_collection()
for monitor in tcps_monitors:
    print "TCP monitors:"
    print monitor.name
    print monitor.interval
    print monitor.timeout

    From tmsh, type list ltm monitor and TAB completion. You will find the list of monitor types.

    In iControl REST, the /mgmt/tm/ltm/monitor returns a list of objects. Each object represents the endpoint for a type: e.g.,

     

           {
            "reference": {
                "link": "https://localhost/mgmt/tm/ltm/monitor/diameter?ver=13.1.0"
            }
        },

     

    For curl users, it's as simple as grepping the link lines:

     

     curl -sku admin: https://localhost/mgmt/tm/ltm/monitor | python -m json.tool | grep link

     

    In Python API, the object is represented as dict, so you can do something like this:

     

    from f5.bigip import ManagementRoot

mgmt = ManagementRoot('mgmtPort', 'user', 'pass')
monitor = mgmt.tm.ltm.monitor.get_collection()

for t in monitor:
    print(t['reference']['link'])

     

    You can use the link value as is to obtain the monitors under a specific type.

    for t in monitorTypes:
    endp = 'mgmt.tm.ltm.monitor.' + t + '.get_collection()'
    try:
        e = eval(endp)                      Get list
        eList = map(lambda x: x.name, e)
        print('{}: {}'.format(t, ','.join(eList)))
    except AttributeError:
        print('{} does not exist.'.format(t))

     

    The code would yield something like this (truncated):

     

    diameters: diameter
dns_s: dns
externals: external
firepass_s: firepass
ftps: ftp
gateway_icmps: gateway_icmp
https: http,http_head_f5
https_s: https,https_443,https_head_f5
