The requirements for the Service Monitor are based on the number of monitored entities. To
see the number of monitored entities, perform the following steps:
Open the Cloudera Manager Admin Console and click
Clusters > Cloudera Management
Service.
Find the Cloudera Management Service Monitored Entities chart.
If the chart does not exist, add it from the Chart Library.
For more information about Cloudera Manager entities, see Cloudera Manager Entity
Types.
