The following properties are configurable for the emmonitorrest service in /etc/opt/teradata/em/emmonitorrest.conf:
| Property | Description | Default value |
|---|---|---|
| CPUInterval | Data collection frequency interval in seconds for metrics in metricGroup CPU | 30 |
| MemoryInterval | Data collection frequency interval in seconds for metrics in metricGroup Memory | 30 |
| DiskInterval | Data collection frequency interval in seconds for metrics in metricGroup Disk/IO | 30 |
| NetworkInterval | Data collection frequency interval in seconds for metrics in metricGroup Network | 30 |
| TomcatPort | Port that tomcat is using for listening | 8090 |
| H2AdminUserName | Admin user name to connect to H2 | admin |
| H2AdminPassword | Password to admin user to connect to H2 | teradata |
| H2RestUserName | User name the emmonitorrest client provides while making a REST call | emem |
| H2RestPassword | Password to H2RestUserName | em |
| H2TCPPort | H2 TCP port | 9092 |
| DaysToHoldData | Maximum number of days the monitored data stays persisted | 5 |
A change in value for CPUInterval, MemoryInterval, DiskInterval and NetworkInterval does not require emmonitorrest service restart. The service needs to be restarted for changes in any of the other properties.
The minimum data collection frequency interval is 30 seconds. If you modify the interval to less than 30, the previous value returns.
