Service Monitor Requirements

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:

  1. Open the Cloudera Admin Console and click Clusters > .
  2. 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.

0-2,000 0-100 1 GB 6 GB
2,000-4,000 100-200 1.5 GB 6 GB
4,000-8,000 200-400 1.5 GB 12 GB
8,000-16,000 400-800 2.5 GB 12 GB
16,000-20,000 800-1,000 3.5 GB 12 GB
Table 2. Clusters with HBase, Solr, Kafka, or Kudu Use these recommendations when services such as HBase, Solr, Kafka, or Kudu are deployed in the cluster. These services typically have larger quantities of monitored entities.
Number of Monitored Entities Number of Hosts Required Java Heap Size Recommended Non-Java Heap Size
0-30,000 0-100 2 GB 12 GB
30,000-60,000 100-200 3 GB 12 GB
60,000-120,000 200-400 3.5 GB 12 GB
