CPU, memory, disk usage and http profile using the BIG-IP Python SDK

I've been busy with the Python SDK for a couple of weeks now. While I managed to get a lot of information out of it, I'm struggling with a couple of API endpoints. Does anyone have an idea where I can find the statistics for CPU, Memory, Disk as well as the http profile? REST endpoints: mgmt/tm/sys/hostInfo (for CPU and memory) mgmt/tm/sys/disk/logical-disk (for disks) mgmt/tm/ltm/profile/http/stats (for http profile)

 

Thanks! Mike

    As shown in the Github Issue 1436, the feature became available from SDK version 3.0.15.

     

    To check the current version on your box, run

     

     pip show f5-sdk

    To upgrade to the latest, run

     

     pip install --upgrade f5-sdk

    A sample code for host_info:

     

    from f5.bigip import ManagementRoot
mgmt = ManagementRoot('xx.xx.xx.xx', 'admin', 'passwd')

host = mgmt.tm.sys.host_info.load()

def recurse(dictionary, level):
    for key, value in dictionary.iteritems():
        if isinstance(value, dict):
            print('{}{}:'.format(' '*level, key))
            recurse(value, level+1)
        else:
            print('{} {} : {}'.format(' '*level, key, value))

recurse(host.raw, 0)

    A sample code:

     

    from f5.bigip import ManagementRoot
mgmt = ManagementRoot('192.168.184.30', 'admin', 'admin')

logicalDisk = mgmt.tm.sys.disk.logical_disks.get_collection()
diskKeys = ['mode', 'size', 'vgFree', 'vgInUse', 'vgReserved']
for ld in logicalDisk:
    print('--- list sys disk logical-disk {} all-properties ---'.format(ld.__dict__['name']))
    for k in diskKeys:
        print('{:<15} {}'.format(k, ld.__dict__[k]))
