Configuration file access with Python

Configuration file access with Python

Use the splunk.bundle module from the Python SDK to access and edit configuration files.

Configuration

Getting and setting stanzas or key/value pairs is the same as any Python dictionary:

        myConf = getConf('prefs', mysessionKey)
        # get the 'default' stanza in the 'prefs' conf file
        s = myConf['default'] 
        # get the 'color' property in the 'default' stanza of the 'prefs' conf
        color = myConf['default']['color']
        # set the 'color' property in the 'default' stanza of the 'prefs' conf
        # this is an immediate write
        myConf['default']['color'] = 'green'

If you are doing a large number of writes, you can defer the commit action:

        myConf.beginBatch()
        myConf['default']['car1'] = 'honda'
        myConf['default']['car2'] = 'bmw'
        myConf['default']['car3'] = 'lexus'
        myConf['default']['car4'] = 'pinto'
        myConf['default']['car5'] = 'VW'
        myConf.commitBatch()

Example

Import the necessary modules:

import from splunk auth 
import splunk.bundle as bu

Get a session key:

mysessionKey=auth.getSessionKey('admin','changeme')

Access the configuration file:

myConf = bu.getConf('alert_actions', mysessionKey)

This example uses the alert_actions.conf file, but you can access any valid configuration file.

Set the mail server attribute in the email stanza in alert_actions.conf:

myConf['email']['mailserver']='smtp.roadrunner.com'

Or do a batch change to multiple attributes and values:

myConf.beginBatch()
myConf['email']['mailserver']='theothers.com'
myConf['email']['format']='csv'
myConf['email']['from']='john_locke'
myConf.commitBatch()
