Thanks Harkishen Singh for your suggestion. But, when we use *container_memory_usage_bytes *instead of *container_memory_working_**set_bytes *it is showing above 55%. Also referred some of the blogs which were also recommending to use *container_memory_working_**set_bytes *instead of * container_memory_usage_bytes * to get the accurate result.
