LDOMs page
LDOM Future Saturation table
Each row in the table corresponds to an LDOM and displays the following metrics:
Certain minimum amount of historical data is required to provide accurate Days to Saturation (DTS) values. Therefore, Yesterday and Last 7 days time filter selection is not applied to DTS calculation. DTS calculation is always based on last 30 days of data.
Field | Description | Statistical Type | Metrics |
|---|---|---|---|
Days to Saturation | The projected amount of time before one of the resources (CPU or MEMORY or STORAGE) runs out of available capacity. | NA | IND_DAYS_TO_SATURATION[1D:7D:30D] |
Bottleneck | The resource predicted to cause performance bottlenecks. Indicates one of the three resources – CPU, MEMORY, STORAGE – as the bottleneck resource. | NA | IND_BNECK_RESOURCE |
LDOM | Name of the logical domain (LDOM). | Last value | NAME |
Host | Name of the host the LDOM belongs to. | Last value | Host name retrieved using relationship VH_CONTAINS_GM |
CPU Util [%] | Percentage of CPU used by the LDOM host. | 95th Percentile | CPU_UTIL |
CPU Trend [%] | Growth rate of CPU utilization of the LDOM host. | Trend | Computed using CPU_UTILMHZ |
CPU Days to Saturation | The projected amount of time before the server runs out of available CPU capacity. | NA | IND_DAYS_TO_SATURATION[CPU] |
Memory Util [%] | Memory used by the LDOM host. | 95th Percentile | MEM_UTIL |
| Real Memory Util [%] | The percentage of real memory currently in use by the server. This metric is reported for Linux/Unix platforms and not reported for Windows. Real memory utilization presents a better picture of the actual memory usage it includes kernel and process memory but excludes file system cache memory; | 95th Percentile | REAL_MEM_UTIL |
Memory Trend [%] | Daily growth rate of memory utilization of the LDOM host. | Trend | Computed using MEM_USED |
| Memory Days to Saturation | The projected amount of time before the LDOM host runs out of memory. | NA | IND_DAYS_TO_SATURATION[MEMORY] |
File System Util [%] | File system space used by the LDOM partition. | 95th Percentile | TOTAL_FS_UTIL |
File System Trend [%] | Daily Growth grate of the file system of the LDOM partition. | Trend | Computed using TOTAL_FS_USED |
| File System Days to Saturation | The projected amount of time before the logical domain runs out of available file system capacity. | NA | IND_DAYS_TO_SATURATION[STORAGE] |

To view details for a specific LDOM
To view the details page for a particular Solaris LDOM, click its (hyper-linked) name under the LDOM column. You can use the sorting and filtering options on the page to find a specific LDOM.
For more information, see Sorting tables in views in the TrueSight console and Using filtering options in views in the TrueSight console.
The LDOM Details page displays information for the selected LDOM under the following sections or panels:
| Section or Panel | Description |
|---|---|
| Summary page | A quick graphical summary of the CPU and memory utilization, and disk and network I/O rate of the LDOM. Core metrics for the selected entity are displayed as analysis charts, depending on available data. At the bottom of each chart is a link that takes you to the Data Explorer view for the specific resource type, and displays charts and information for a larger set of metrics. The data displayed in Data Explorer view charts for any resource part of this view category, is based on the time filter that is applied to the primary view in this tab. You can select other time filter options to view charts over a different time resolution. For more information, see LDOM Domain page in the Solaris Data Explorer view. |
| Configuration Details page | Configuration information about the host. |
| File Systems page | Displays the file system summary table. For more information, see File systems table. |
| Related Information panel | Links to detailed pages for thresholds, process profile, workload profile, command profile, and user profile. For more information, see Viewing related information. |
| Tags panel | List of tags that are associated with the host. You can assign or remove tags by using the Edit Tags option from the Tags action menu. |
Elements table in File systems page
| Column | Description |
|---|---|
| Name | The name of the file system. |
| File System Size [GB] | Total size of the file system on disk. |
| File System Used [%] | Total disk space utilization, in percentage, by the file system. |
| Trend [%] | Growth rate of the file system. |
| Days to Saturation | The projected amount of time before the file system runs out of available storage capacity. |
| Read Rate [MB/s] | The number of reads by a specific file system, measured in in Megabytes per second. |
| Write Rate [MB/s] | The number of writes by a specific file system, measured in in Megabytes per second |
| Read Rate [op/s] | The number of read request operations by a specific file system, measured in operations per second. |
| Write Rate [op/s] | The number of write request operations by a specific file system, measured in operations per second |
| Total Rate [op/s] | The total number of read + write request operations by a specific file system, measured in operations per second |
