RucioSynchronizerAgent

mod:

RucioSynchronizer

Agent that synchronizes Rucio and Dirac

The following options can be set for the RucioSynchronizerAgent.

RucioSynchronizerAgent options

RucioSynchronizerAgent
{
  #Time between cycles in seconds
  PollingTime = 120
}

class DIRAC.ConfigurationSystem.Agent.RucioSynchronizerAgent.RucioSynchronizerAgent(agentName, loadName, baseAgentName=False, properties={})

Bases: AgentModule

class RucioSynchronizerAgent

Agent that synchronizes Dirac users and SEs to Rucio.

__init__(agentName, loadName, baseAgentName=False, properties={})

Common __init__ method for all Agents. All Agent modules must define: __doc__

They are used to populate __codeProperties

The following Options are used from the Configuration: - /DIRAC/Setup - Status - Enabled - PollingTime default = 120 - MaxCycles default = 500 - WatchdogTime default = 0 (disabled) - ControlDirectory control/SystemName/AgentName - WorkDirectory work/SystemName/AgentName - shifterProxy ‘’ - shifterProxyLocation WorkDirectory/SystemName/AgentName/.shifterCred

It defines the following default Options that can be set via Configuration (above): - MonitoringEnabled True - Enabled True if Status == Active - PollingTime 120 - MaxCycles 500 - ControlDirectory control/SystemName/AgentName - WorkDirectory work/SystemName/AgentName - shifterProxy False - shifterProxyLocation work/SystemName/AgentName/.shifterCred

different defaults can be set in the initialize() method of the Agent using am_setOption()

In order to get a shifter proxy in the environment during the execute() the configuration Option ‘shifterProxy’ must be set, a default may be given in the initialize() method.

am_Enabled()

am_createStopAgentFile()

am_getControlDirectory()

am_getCyclesDone()

am_getMaxCycles()

am_getModuleParam(optionName)

am_getOption(optionName, defaultValue=None): Gets an option from the agent’s configuration section. The section will be a subsection of the /Systems section in the CS.

am_getPollingTime()

am_getShifterProxyLocation()

am_getStopAgentFile()

am_getWatchdogTime()

am_getWorkDirectory()

am_go()

am_initialize(*initArgs)

Common initialization for all the agents.

This is executed every time an agent (re)starts. This is called by the AgentReactor, should not be overridden.

am_setModuleParam(optionName, value)

am_setOption(optionName, value)

am_stopExecution()

beginExecution()

endExecution()

execute()

Create RSEs in Rucio based on information in Dirac CS.

Returns:: S_OK if all vital VO specific synchronisation succeeded, otherwise S_ERROR
Return type:: dict

executeForVO(vo)

Execute one SE and user synchronisation cycle for a VO.

Parameters:: vo (str) – Virtual organisation name.
Returns:: S_OK or S_ERROR
Return type:: dict

finalize()

initialize()

agent’s initialisation

Parameters:: self – self reference

DIRAC.ConfigurationSystem.Agent.RucioSynchronizerAgent.configHelper(voList)

A helper function to gather necessary Rucio client options from the CS.

Parameters:: volist – list of VO names, or a VO name (str)
Returns:: a dictionary of a form {vo: params, vo: params,}
Return type:: dict

DIRAC.ConfigurationSystem.Agent.RucioSynchronizerAgent.getStorageElements(vo)

Get configuration of storage elements

Parameters:: vo – VO name that an SE supports
Returns:: S_OK/S_ERROR, Value dictionary with key SE and value protocol list
