Overview

This repository is a fork of https://github.com/amccurdy/zenoss_api and currently the original python library ZenAPIConnector.py still exists in this repo. A new python library zenApiLib.py has been introduced with this forked repo.

zenApiLib

File: zenApiLib.py

Description: New python library introduced in this git-hub repository

Functionality:

• leverages python logging library
• paging api support; leverage router methods 'limit' parameter to break large results queries into manageable chunks
• api result error checking
  • Content-Type JSON, return decoded json object
  • Content-Type HTML, return error w/ HTML page title
  • Misc
• api call error checking
  • Validate specified Router exists
  • Validate called method exists
• backward compatibility w/ zenoss_api.ZenAPIConnector.ZenAPIConnector
• support multiple zenoss instance definitions in credential file
  • credential file name defaults to 'creds.cfg' and same directory as zenApiLib.py file
  • ability to specify credential file
• 'zenApiCli.py' script available. For simple, command line API interaction. Can be easily incorporated with existing shell scripts.

Pre-requisites:

This python library depends on the following: requests, pyOpenSSL, ndg-httpsclient, pyasn1

You can install those quickly with pip:

yum -y install python-pip
pip install requests pyOpenSSL ndg-httpsclient pyasn1

Environment:

If your script(s) are not in the same directory as zenApiLib.py or the standard python lib directories, then update your $PYTHONPATH environment variable to include that directory.

Note: The credentials creds.cfg file by default is expected to be in the same directory as zenApiLib.py. A different location can be specified at instantiation.

Usage:

zenApiCli.py

1. Script help output:

   $ ./zenApiCli.py --help
     usage: zenApiCli.py [-h] [-v LOGLEVEL] [-t TIMEOUT] -r routerName -m
                         routerMethodName [-c credsSection] [-p credsFilePath]
                         [-d KEY1=VAL1,KEY2=VAL2...] [-x fieldName.fieldName...]
   
     Command Line Interface to Zennos JSON API, can be used to make simple API
     calls.
   
     optional arguments:
       -h, --help            show this help message and exit
       -v LOGLEVEL           Set script logging level (DEBUG=10, INFO=20, WARN=30,
                             *ERROR=40, CRTITICAL=50
       -t TIMEOUT            Override API call creds file timeout setting
       -r routerName         API router name
       -m routerMethodName   API router method to use
       -c credsSection       zenApiLib credential configuration section (default)
       -p credsFilePath      Default location being the same directory as the
                             zenApiLib.pyfile
       -d KEY1=VAL1,KEY2=VAL2...
                             Parameters to pass to router's method function
       -x fieldName.fieldName...
                             Return value from API result field. Default:
                             'result.success'. Special keyword 'all' to dump API
                             results.
   

2. Send an event:

   ./zenApiCli.py -r EventsRouter -m add_event -d summary="this is a test",component="test" -d device="Null" -d severity=4,evclass="/Status" -d evclasskey="sma"
   

3. Get device's productionState value:

   ./zenApiCli.py -r DeviceRouter -m getDevices -d uid="/zport/dmd/Devices/ControlCenter" -d params="{'ipAddress': '10.88.111.223'}" -x result.devices.0.productionState
   

4. Get all devices in a deviceClass and their statuses:

   ./zenApiCli.py -r DeviceRouter -m getDevices -d uid="/zport/dmd/Devices",keys='["name","status"]' -x result.devices.*.name -x result.devices.*.status
   

zenApiLib.py

Once the zenApiLib library is imported you can then instantiate zenConnector a few different ways:

1. get all triggers

   import zenApiLib
   zenApi = zenApiLib.zenConnector()
   zenApi.setRouter('TriggersRouter')
   print zenApi.callMethod('getTriggers')
   

2. get all devices

   import zenApiLib
   dr = zenApiLib.zenConnector(routerName = 'DeviceRouter')
   print dr.callMethod('getDevices')
   

3. copy trigger from one zenoss instance to another

   import zenApiLib
   tr5 = zenApiLib.zenConnector(section = '5x', routerName = 'TriggersRouter')
   tr6 = zenApiLib.zenConnector(section = '6x', routerName = 'TriggersRouter')
   migrate = tr5.callMethod('getTrigger', uuid = "e9ac462f-a80e-4f62-83e2-5f410818d782")
   # TODO: below is incorrect, but you get the general idea
   tr6.callMethod('addTrigger' **dict(migrate['result'])
   

4. get all devices, via multiple queries. limits max number of results per query to two.

   import zenApiLib
   dr = zenApiLib.zenConnector(routerName = 'DeviceRouter')
   for apiResp in dr.pagingMethodCall('getDevices', limit = 2, keys = ["productionState", "id"]):
      print apiResp
   

5. send an event & check success

   import zenApiLib
   er = zenApiLib.zenConnector(routerName = 'EventsRouter')
   evtResp = er.callMethod('add_event', 
       summary = "Device in Maintenance too long !",
       device ="localhost",
       component = "",
       severity = 2,
       evclasskey = "",
       evclass = "/Status/Zenoss"
   )
   if not evtResp['result']['success']:
       print("sendEvent - nonSucessful results\n%s" % evtResp)
   

API Router Helper Libraries:

Files: zenApiDeviceRouterHelper.py, zenApiImpactRouterHelper.py

Helper libraries that are router specific, should contain common, repeatbly used functionality.
