Using filtering options in views in the TrueSight console

Using view-level filters

At the view level, you can specify the following filters:

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.

To use domain filters

The following example illustrates how to use domain filters. 

1. Navigate to the required view. The available filters are displayed at the top of the view. For this example, only the domain filter is displayed as shown in the following image:
   
2. Click the action menu next to No Domain Filter and click Apply Domain Filter.
   
3. In the Apply Domain Filter dialog box, a list of available domains are displayed.
   
   If there are subdomains under a parent domain, you can expand the parent domain to display the sub-domains under it.
   If the list is long, you can also type a string in the Search field and click Search. A list of names containing the search string is displayed and you can select the domain you require.
4. Click Apply.
   The view displays details of only the selected domain. The name of the domain is displayed at the top of view as shown in the following image:
   
   
   To clear the filter, click the action menu  next to Domain: <domainName> and click Clear Domain Filter as shown in the following image:
   
   
   

Similarly, you can use tag, time, and time resolution filters.

To use tag 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.

To use time filters

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:

• Last 30 days: Displays data for the last 30 days, excluding today.
• Last 7 days: Displays data for the last 7 days, excluding today.
• Yesterday: Displays data for the previous day, excluding today.
• Define Period: Enables you to define a custom time range. Use the calendar to select the start and end dates for your custom time period. This option is not available for all views.

1. 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:
   

2. To view data for the last seven days, click the action menu next to Last 30 days and click last 7 days.
   
   The view updates to show data only for the last seven days, as shown in the following image:
   

To use time resolution filters

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. 

• Detail: Displays the charts with the resolution that the ETL used to populate data in the domain. For example, for a VMware vSphere view, the ETL populates data every 15 minutes. By selecting Detail time resolution, you can display the charts with data points for every 15 minutes. 
• Hourly: Displays charts with a data point for every hour.
• Daily: Displays charts with a data point for every day.

Using system type filters

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.

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).

To use system type filters

1. Click next to the displayed system filter, and click Select <filterName>.
2. In the Select <filterName> box that opens, a list of systems corresponding to the type, are displayed.
   In this example, a list of virtual host systems are displayed, since the Virtual Host - KVM filter is applied.
   If the list is long, you can also type a string in the Search field and click Search. A list of names containing the search string is displayed and you can select the cluster you require.
   
3. Select the required system and click Apply.
   In this example, the pl-aus-bco-qa04 virtual host system is selected.
   The view displays the details of only the selected system, in this case the pl-aus-bco-qa04 virtual host, as shown in the following image.
   
4. (Optional): To use subresource filter, perform the following steps:
   1. Click next to the displayed subresource filter, and click Select <filterName>.
   2. In the Select <filterName> box that opens, a list of subresources corresponding to the system type, are displayed.
   3. Select the required system and click Apply.
      In this example, SDC Disk is selected.
      

Using data mart filters

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.

To use data mart filters

1. Click next to the displayed filter,and click Apply <filterName> Filter.
   In this example, the Cluster ID Filter is applied.
   
2. In the Search for <filterName> box that opens, a list of items corresponding to the type of filter, are displayed.
   In this example, a list of clusters are displayed, since the Cluster Filter is applied.
   If the list is long, you can also type a string in the Search field and click Search. A list of names containing the search string is displayed and you can select the cluster you require.
   
3. Select the cluster and click Apply.
   In this example, the bcoqa01 cluster is selected.
   The summary table displays the details of only the selected item, in this case the bcoqa01 cluster, as shown in the following image.
   
   The name of the cluster is displayed next to the Cluster filter, at the top of the summary table.
