Hi Yuvaraaj,
You might need to increase:
introscope.enterprisemanager.agent.metrics.limit
introscope.enterprisemanager.metrics.live.limit
introscope.enterprisemanager.metrics.historical.limit
However, this will impact the EM and/or cluster performance.
I suggest you to review the additional suggestions I included in the below thread:
Unable to update load balancing for collector
