    Hello, 

    Anyone knows how to allow RSP probe to autodiscover the FS or total Physical memory?

    This is in order not to make a manual rediscovery cause this could allow some FS not being monitored or if someone changes the Physical Memory of a system its possible that noone notice it cause it wont show the new amount of memory until someone rediscovers it.

    rsp has a metric which reports

    QOS_MEMORY_PHYSICALMegabytes

    The size of the physical memory available in the system in megabytes.

    Yes i know, but if you take a look ath the lua script memory.lua  it only gets the value for TOTAL MEMORY when you make a discovery or rediscovery in the probe, and the it saves it to the internal table discovery_memory. 

     

    When RSP takes the metrics, it quryes the internal database looking for the TOTAL memory value and then it calculates the percentages using the values it get from the script it uses to get the memory metrics and the Total memory value it saved when you did the discovery or rediscovery. So if you add memory to a machine and you didnt rediscover it  if the previous memory was 16gb and the now it has 32gb and the proceses are using 8gb the QOS for MEMORY PERCENTAGE USAGE will still show 50% (100*8gb/16gb) in stead of 25% (100*8gb/32gb)

    There is a rsp callback discover_host that can probably be scripted using pu.exe.
