Indicators used in the Business Services view
Indicators are computed metrics. They provide an indication of how a system is performing from the capacity and forecasting perspective. They are derived information and not measurements. With indicators, you can get additional insight into the status of the managed entity.
BMC Helix Capacity Optimization produces indicators on Risk, Usage, and Days to saturation for each service pool that you have defined:
- A Risk indicator counts any indication that CPU, memory, or storage resource of server in a service pool is either already saturated or will soon be experiencing capacity contention. If you see such an indication for a service pool, you would like to pay attention to the server to find out whether there is a risk to be addressed.
The risk indicator is a score value ranging from 1 to 100, higher being worse. The score is computed by considering risks based on CPU, memory, and storage risk scores of the contained servers. - A Usage indicator counts the level of usage per resource, so that you can track which service pools have consumed the excess capacity. The usage score is computed by aggregating usage based on CPU, memory, and storage usage scores of the contained servers.
- A Days to saturation indicator indicates the estimated number of days before the CPU, memory, and storage resources achieve the configured threshold.
For each business service or application, the indicators values are calculated based on the indicator values of contained service pools. The last 30 days of data is considered to calculate the indicator values. For more information about indicators, see Indicators.
In the context of the business service and service pool, a server means a virtual machine of any of the supported technologies or a standalone system. In the rest of the documentation of this feature, it is referred to as server. The servers of the following technologies are supported: VMware, AWS, Azure, Google Cloud, AIX, Solaris, HP-UX, Hyper-V, KVM, Xenserver, Standalone systems.
| Indicator | Resource | Displayed on | Description |
|---|---|---|---|
Risk (IND_RISK_SCORE) | |||
| Risk (Business service) | Risk pie chart, Business Services summary table | Indicates the overall risk of the business service, calculated by taking the maximum of the risk values of the contained applications. If applications are not available, risk values of service pools are considered. For example, if the business service contains four applications, then the highest risk score out of these four is used as the risk score for the business service. | |
| Risk (Application) | Business Service summary table | Indicates the overall risk of the application, calculated by taking the maximum of the risk values of the contained service pools. | |
Risk (Service pool) | Risk | Business Services summary table, Summary tab in the Service Pool Details page | Indicates the overall risk of the service pool, calculated by taking the highest risk score of CPU, Memory, Storage resources of the service pool. |
| CPU | Summary tab in the Service Pool Details page | Maximum of the CPU risk scores of the contained servers in the service pool. CPU risk score of the contained servers are computed using key indicators such CPU days to saturation and CPU utilization. | |
| Memory1 | Summary tab in the Service Pool Details page | Maximum of the Memory risk scores of the contained servers in the service pool. Memory risk score of the contained servers are computed using key indicators such as memory days to saturation and memory utilization. | |
| Storage | Summary tab in the Service Pool Details page | Maximum of the Storage risk scores of the contained servers. Storage risk score of the contained servers are computed using key indicators such as storage days to saturation and storage utilization. | |
| Risk (Server) | Risk | Contained Elements tab in the Service Pool Details page | Indicates the overall risk of the server, calculated by taking the maximum of the usage of CPU, Memory, Storage resources of the server. |
| CPU | Contained Elements tab in the Service Pool Details page | CPU risk score of the server. | |
| Memory1 | Contained Elements tab in the Service Pool Details page | Memory risk score of the server. | |
| Storage | Contained Elements tab in the Service Pool Details page | Storage risk score of the server. | |
Usage (IND_USAGE_SCORE) | |||
Usage (Business service) | Usage histogram, Business Services summary table | Indicates the overall usage of the business service, calculated by taking the average of the usage values of the contained applications. If applications are not available, usage values of service pools are considered. | |
| Usage (Application) | Business Services summary table | Indicates the overall usage of the application, calculated by taking the average of the usage values of the contained service pools. | |
Usage (Service pool) | Usage | Business Services summary table, Summary tab in the Service Pool Details page | Indicates the overall usage of the service pool, calculated by taking the average of the usage of CPU, Memory, Storage resources of the service pool. |
| CPU | Summary tab in the Service Pool Details page | Average of the CPU usage of the contained servers. | |
| Memory1 | Summary tab in the Service Pool Details page | Average of the memory usage of the contained servers. | |
| Storage | Summary tab in the Service Pool Details page | Average of the storage usage of the contained servers. | |
| Usage (Server) | Usage | Contained Elements tab in the Service Pool Details page | Indicates the overall usage of the server, calculated by taking the average of the usage of CPU, Memory, Storage resources of the server. |
| CPU | Contained Elements tab in the Service Pool Details page | CPU usage score of the server. | |
| Memory1 | Contained Elements tab in the Service Pool Details page | Memory usage score of the server. | |
| Storage | Contained Elements tab in the Service Pool Details page | Storage usage score of the server. | |
Days to saturation (IND_DAYS_TO_SATURATION) | |||
Days to saturation (Business service) | Saturation by Service Importance bubble chart, Business Services summary table | Indicates the days to saturation value for the business service, calculated by taking the minimum of the days to saturation values of the contained applications. If applications are not available, days to saturation values of service pools are considered. For example, if the business service contains four applications, then the lowest days to saturation value out of these four is used as the days to saturation value for the business service. | |
Days to saturation (Application) | Business Services summary table | Indicates the days to saturation value for the application, calculated by taking the minimum of the days to saturation values of the contained service pools. | |
Days to saturation (Service pool) | NA | Indicates the days to saturation of the service pool. It is the estimated number of days before the CPU, memory, and storage resources achieve the configured threshold. | |
| CPU | NA | Minimum of the CPU days to saturation indicators of the contained servers. | |
| Memory | NA | Minimum of the memory days to saturation indicators of the contained servers. | |
| Storage | NA | Minimum of the storage days to saturation indicators of the contained servers. | |
1 For VMware, AWS, Azure, Google Cloud, Hyper-V, KVM, and Xenserver technologies, if the virtual node data is available, the memory score is computed based on the virtual node memory data. Otherwise, it is computed based on the memory of the virtual machine.
