Just wondering what’s the criteria for dfm to determine the value of <host-perf-status> :

 

          <host-info>

               <id>7847</id>

               <name>waqar</name>

               <host-id>7847</host-id>

......

               <host-perf-info>

                    <host-perf-status>unknown</host-perf-status>
  ......

               <id>114</id>

               <name>wasim</name>

               <host-id>114</host-id>

......

               <host-perf-info>

                    <host-perf-status>normal</host-perf-status>

 


Also want to know the criteria about <host-communication-status>.

 


Thanks,

Bing

    Hi Bing,

     

    If the host-perf-status is 'Unknown', object must have been recently added and hence performance data has not been collected yet.

     

    The OnCommand Unified Manager API Documentation gives the following information:

    host-perf-status : Current status of the host based on performance events

    Possible status values:

      • unknown: An object has an unknown status when it transitions from one state to another. Ideally, an object will have this status briefly. For example, when an object has been added, but not yet discovered.
      • normal: An object has normal status when it is working within the thresholds specified in DFM.
      • information: The information events are normal occurrences on an object for which you can define alarms.
      • unmanaged: An object is considered to be unmanaged when the login and password are not set for the storage system or agent.
      • warning: An object has the warning status when an event related to the object occurred that an administrator should know about. The event will not cause service disruption.
      • error: An object has error status when it does not cause any service disruption, but it may affect performance.
      • critical: An object has critical status when it is still performing, but service disruption may occur if corrective action is not taken immediately.
      • emergency: An object is in emergency status when it stops performing unexpectedly and could lose data.

     

    host-communication-status :

    Whether we are able to establish a connection to validate the host credentials. Valid only for storage systems and Host Agents. Possible values: "unknown", "up", or "down".

     

    Regards,

    Pavan
