VirtualMachineMonitorAgent

VirtualMachineMonitorAgent plays the role of the watch dog for the Virtual Machine

class DIRAC.WorkloadManagementSystem.Agent.VirtualMachineMonitorAgent.VirtualMachineMonitorAgent(agentName, loadName, baseAgentName=False, properties={})

Bases: AgentModule

__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_checkStopAgentFile()
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_removeStopAgentFile()
am_secureCall(functor, args=(), name=False)
am_setModuleParam(optionName, value)
am_setOption(optionName, value)
am_stopExecution()
beginExecution()
endExecution()
execute()
finalize()
initialize()

Agents should override this method for specific initialization. Executed at every agent (re)start.
