Hostd.log file reports CIM monitoring messages repeatedly

Products

• VMware vSphere ESXi

Issue/Introduction

• The hostd.log file located at /var/log/ reports the Common Information Model (CIM) messages repeatedly.
• In the hostd.log file, you see these messages every five minutes:
  
  [2011-02-01 17:37:44.783 FFF0BE90 info 'Vmomi'] Activation [N5Vmomi10ActivationE:0x2a9846d0] : Invoke done [waitForUpdates] on [vmodl.query.PropertyCollector:ha-property-collector]
  [2011-02-01 17:37:44.783 FFF0BE90 verbose 'Vmomi'] Arg version:"963"
  [2011-02-01 17:37:44.784 FFF0BE90 info 'Vmomi'] Throw vmodl.fault.RequestCanceled
  [2011-02-01 17:37:44.784 FFF0BE90 info 'Vmomi'] Result:
  (vmodl.fault.RequestCanceled) {
  dynamicType = <unset>,
  faultCause = (vmodl.MethodFault) null,
  msg = "",
  }

Resolution

These messages are reported due to the way in which Common Information Model (CIM) agent connects to the hostd management agent. CIM waits for updates from hostd which time out every 5 minutes. When there is a time out, it issues CancelWaitForUpdates to cancel the call and the initial HTTP connection is already terminated. This results in the Connection reset by peer message. These messages can be safely ignored.

Note: These messages are useful for debugging issues in other cases.

 

If you are not using CIM, you can disable it. For more information, see How to disable the CIM agent on the ESX/ESXi host (1025757).

 

Note: CIM monitors the status of your hardware. If you disable CIM monitoring, your hardware will not be monitored and you cannot view the status of your hardware within the Hardware Status tab of vCenter Server. You should disable this only if you have a third party agent, such as Dell Open Manage or HP Open View, monitoring your hardware status.
