Hi everyone,
We have a process for deploying code to web servers. When we put the web server into 'maintenance' mode to do the code deploy, we'd also like to unmanage the node in SolarWinds as well. I'm not sure if I've run into a bug or if I'm simply doing something wrong. Anyway I hope some of the great folks on the formus can see what's going on.
I'm using v1.10 of the SDK and Python 2.7.something
As you'll see in the end, the error I'm getting is, "TypeError: unbound method _json_serial() must be called with SwisClient instance as first argument (got datetime instance instead)".
Here's the very basic script, it's mainly from the SwisClient.py example
import requests
import json
from getpass import getpass
from datetime import datetime, timedelta
import SwisClient
npm_server = "myOrionServer.local"
username = raw_input("Username: ")
password = getpass("Password: ")
swis = SwisClient(npm_server,username,password)
node = 'myNode.local'
results = swis.query("SELECT NodeID from Orion.Nodes WHERE NodeName='" + node + "'")
interfaceId = results["results"][0]["NodeID"]
netObjectId = "N:{}".format(interfaceId)
now = datetime.utcnow()
tomorrow = now + timedelta(days=1)
swis.invoke("Orion.Nodes", "Unmanage", netObjectId, now, tomorrow, False)
Here's the obvsucated values for results, interfaceId, netObjectId, now, tomorrow:
In [261]: results
Out[261]: {u'results': [{u'NodeID': 4526}]}
In [262]: interfaceId
Out[262]: 4526
In [263]: netObjectId
Out[263]: 'N:4526'
In [265]: now
Out[265]: datetime.datetime(2015, 6, 10, 20, 34, 46, 345759)
In [266]: tomorrow
Out[266]: datetime.datetime(2015, 6, 11, 20, 34, 46, 345759)
-=-=-=-=-=- So everything looks good so far -=-=-=-=-=-
Here's where I get an error
In [267]: swis.invoke("Orion.Nodes", "Unmanage", netObjectId, now, tomorrow, False)

Sooooo, I'm not awesome at Python, but it seems like I maybe should have the Node's Uri in there somewhere? I don't know, this is my first time writing for SolarWinds in Python, I'd much prefer to use PowerShell, but the 'calling server' is Linux.

On a side note, a dictionary containing a list of dictionaries.. that's just plain evil.. I still can't wrap my head around the 'pythonic' way to get at the key, values pairs for the dictionary contained in the list.
Thanks,
Jim
