The requirements for the Host 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 .
- Find the Cloudera Management Service Monitored Entities chart. If the chart does not exist, add it from the Chart Library.
|Number of Hosts||Number of Monitored Entities||Heap Size||Non-Java Heap Size|
|0-200||<6k||1 GB||2 GB|
|200-800||6k-24k||2 GB||6 GB|
|800-1000||24k-30k||3 GB||6 GB|
Ensure that you have at least 25 GB of disk space available for the Host Monitor, Service Monitor, Reports Manager, and Events Server databases.
