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

I added the question on the Github page as that seems like a better location for such a query. it can be followed here: CPU, memory, disk usage and http profile using the BIG-IP Python SDK · Issue #1436 · F5Networks/f5-common-python · GitHub

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]))
