Splunk Apps » RADIUS Authentication

Some sample code to get the base path:

import splunk.clilib.bundle_paths as bp
os.path.join(bp.get_base_path(), 'search', 'lookups')

I'm not sure how or if this can be made search head compatible since the script that currently reads items from the conf system.

Below are some details about how the shared storage is determined:

From bundle_paths.py:

def get_shared_storage():
    """ 
    If search head pooling is enabled, return the location of shared storage.
    Otherwise, return an empty string.
    """ 
    try:
        state   = comm.getConfKeyValue('server', 'pooling', 'state')
        storage = comm.getConfKeyValue('server', 'pooling', 'storage')
        if ((state == 'enabled') and (len(storage) > 0)):
            return storage
    except Exception, e:
        pass
    return ''

From cli_common.py:

def getConfKeyValue(confName, stanza, key):
  stanza = getConfStanza(confName, stanza)
  try:
    return stanza[key]
  except KeyError:
    raise ParsingError, "no '%s' key exists in the '%s' stanza in %s.conf.  Your configuration may be corrupt or may require a restart." % (key, stanza, confName)

def getServerConfKeyValue(key):
  return getConfKeyValue("server", "sslConfig", key)
def getWebConfKeyValue(key):
  return getConfKeyValue("web", "settings", key)

def getConfStanza(confName, stanza):
  cacheConfFile(confName)
  try:
    return confSettings[confName][stanza]
  except KeyError:
    raise ParsingError, "no '%s' stanza exists in %s.conf.  Your configuration may be corrupt or may require a restart." % (stanza, confName)

def cacheConfFile(confName):
  global confSettings
  if confName in confSettings:
    return # do nothing if cache exists.

  # cli.py sets this value to False as soon as it loads.  the CLI doesn't rely
  # on the cached files because:
  # - it doesn't have to.
  # - the system user running the CLI command may not have permission to write
  #   to the merged config file location.
  # - concurrent CLI invocations would clobber each other's merged files.

  useCachedConfigs = (("useCachedConfigs" in dir(__main__)) and (__main__.useCachedConfigs,) or (True,))[0]
  # this will not always eval to True; see http://www.diveintopython.net/power_of_introspection/and_or.html#d0e9975, Example 4.18

  mergedPath = os.path.join(splunk_home, "var", "run", "splunk", "merged", confName + ".conf")
  if useCachedConfigs and os.path.exists(mergedPath) and os.path.getsize(mergedPath) > 0:
    logger.debug("Preloading from '%s'." % mergedPath)
    confSettings[confName] = readConfFile(mergedPath)
  else:
    logger.debug("Running btool for '%s.conf'." % confName)
    confSettings[confName] = getMergedConf(confName)
