At the view level, you can specify the following filters:
|Domain filter||Filter data based on a specific domain. The default value is No filter.|
Filter data based on a specific tag. For example, you can display only those systems with tags "x86" and "VMware".
For more information on tags, see Working with tag filters. The default value is No filter.
Filter data based on a specific time period. For example, Yesterday, Last 7 days, Last 30 days. Based on the time filter selected, data only for that time period is displayed. For example, if you know that a specific time period holds data associated with an incident or planned intervention, you can use an appropriate time filter to display data that you can better analyze. The default value is Last 30 days.
|Time resolution filter|
Analyze peaks in granular data by modifying the time resolution for charts in a view. The default value is Automatic Resolution.
The filter that you apply to a view is preserved during the active logon session. After you re-log on, the view pages display the default filters.
You can bookmark the applied filter in your browser.
In custom views:
The following example illustrates how to use domain filters.
Similarly, you can use tag, time, and time resolution filters.
TrueSight Capacity Optimization provides a set of useful tags that are categorized in groups. You can also define custom tags for your specific needs. You can use tags to search for entities, and to create entity filters that will list all the entities matching a particular tag pattern.
You can use tags to filter what to display in a view. Tags are available for both out-of-the-box and custom views. To use tags in custom views, first ensure that the tag filter is enabled.
For out-of-the-box views, you can also create temporary tags for information that you require only for your current login session. In case, you want to reuse the temporary tag in the future, you can also save it. For detailed information on temporary tags, see Working with tag filters.
For more information about tags, see Working with tags.
By default, the summarization time range for all metrics is set to Last 30 days. You can select an alternate range from the following available options:
Navigate to the required view. The available filters are displayed at the top of the view. In this example, the Last 30 days time filter is the default filter used, as shown in the following image:
The time resolution filter is available only in view pages that display charts. The filter is to be used in conjunction with the Time filter to obtain detailed data in the charts.
You can choose any of the following options for this filter:
Automatic Resolution: Displays charts with a resolution that is based on the time range as selected in the Time filter:
|Time range selection||Time resolution selected|
|Greater than 365 days||Monthly|
|Greater than 60 days||Daily|
|Greater than one day||Hourly|
|For other range||Detail|
This is the default and recommended option.
When you configure a custom view page using the Data explorer or System details template, you can set the system type filter. You can then use the system type filter in the view mode, to display information of only the selected system type.
The system type filters are available for selection only if the view page is a tabbed page in the custom view. The system type filters are not available in the full-screen mode.
In the edit mode, you can select one base system type filter and up to two additional filters. If you do not know the exact system whose data you want to display, you can add additional filters to restrict the number of systems to choose from.
For example, if you select VMware Virtual Machine as the base system type filter, you can select VMware Virtual Host and VMware Virtual Cluster as the additional filters that to restrict the number of VMware Virtual Machine systems to choose from.
In the view mode, you can directly select the system type, without applying the additional filters.
You can use the system type filter name to manage the behavior of system type filter across different pages of a view. For instance, to retain the filter value while navigating across different pages of a view, set the same system type filter name in the required pages of the view. To ensure that filter values are different while navigating across different pages of a view, set different name for system type filter in the required pages of the view.
You can additionally filter the details for a selected system using the subresource filter. You can enable this filter when you configure a custom view page using the Data explorer or System details template. This filter enables you to view the storage and network interface details according to the available subresources (BY metrics).
For summary tables in both out-of-the-box and custom views, you can use data mart filters to further refine the scope of your analysis. Data mart filters make it easier to work on a subset of data.
In custom views, when you configure them, you must first select the data mart filters to be able to use them.
The data mart filters are displayed on top of the summary table as shown in the following image:
In this example, a Cluster filter and Host filter are displayed. In custom views, the number of filters displayed depend on how many filters you select, while creating the custom views.
