    Hi Elvis L,

    The monitor entry point of all resources have basically 3 return values for the state of a resource.  The states are Online, Offline or Unknown.  If the Monitor entry point is not able to determine if a resource is Online or Offline then it returns Unknown.

    The Unknown warning is just to let you know that VCS was unable to determine the known state of the resource.  Given that the state of the resource is unknown by VCS, VCS will not be able to control the resource.  In other words, VCS can not online or offline a resource that is in an Unknown state.

    Most of the time there is nothing really reported in the Engine log for this.  You might find something in the agent specfic log on the node that was having problems probling the resource.  But you might not.  If you don't, then try increasing the LogDbg settings on that resource to increase logging and wait for the issue to reoccur.

    Thanks,

    Wally

     

    FYi - There are actually 10 return codes for Online state with increasing levels of confidence in the Online state of a given resource.  The 3 return states that I mentioned are for simlicity.

Mike and Gaurav,

appreciate the analysis done here. there was not even a single entry of that report on the log (both engineA and Netlsnr). However, I do notice from sar the CPU did spike within +-5 mins at the moment the notification came. Just to update the situation, I eventually got the error below approx 2 hours later. System CPU was also exhibiting spike at the same interval mentioned above. Could this possibly link to CPU spike or there was an issue with the Netlsnr monitoring script interval?
