ThanksDdhruvraj. The interface looks useful for the purpose. However, 
the current BMCWEB implementation references
https://github.com/openbmc/bmcweb/blob/master/redfish-core/lib/log_services.hpp 
[com.intel.crashdump]
constexpr char const* crashdumpPath = "/com/intel/crashdump";

constexpr char const* crashdumpInterface = "com.intel.crashdump";
constexpr char const* crashdumpObject = "com.intel.crashdump";

https://github.com/openbmc/phosphor-dbus-interfaces/blob/master/yaml/xyz/openbmc_project/Dump/Entry/System.interface.yaml 
or 
https://github.com/openbmc/phosphor-dbus-interfaces/blob/master/yaml/xyz/openbmc_project/Dump/Entry/FaultLog.interface.yaml 
is it exercised in Redfish logservices?
