Is there any way to make it monitor an individual process on a server
for processes that are long-running but occasionally restarted? That
is, pick up the index by matching a string in
HOST-RESOURCES-MIB::hrSWRunName then monitor the values for that index
in HOST-RESOURCES-MIB::hrSWRunPerfCPU and
HOST-RESOURCES-MIB::hrSWRunPerfMem?
