The Hosts tab enables you to create host profiles of target computers (where your data resides). While creating the host profile, you can also include details of the agent responsible for collecting the data. For more information, seeAgent types.
By creating a host, you can capture various inputs such as tags, group access permissions, and Agent details and then directly inherit this information while creating data collectors. This means while creating a data collector, you need not enter these details again.
Also, by associating a collection profile with a host, you can automatically create multiple data collectors (displayed under Administration > Data Collectors) and start data collection. At the time of associating collection profiles, you can also override macro values in that collection profile at run time. Note that this change does not apply to the original collection profile listed under the Collection Profiles tab, instead it is only applied at run time for creating data collectors with the overridden macro values.
The Hosts tab also helps you manage the Collection Stations and Collection Agents connected with the product. When you install an Agent, a host profile corresponding to that Agent is automatically displayed on the Hosts tab.
The following information can help you understand various aspects about managing and creating hosts:
The Hosts tab allows you to manage hosts. To access this tab, navigate to Administration > Hosts. From here, you can perform the following actions:
Add a new host.
For detailed instructions on adding a host, see Adding hosts.
|Edit Host||Edit the selected host.|
|View Host||View details of the selected host.|
|Delete Host||Delete the selected host.|
In the search bar, at the top-right side of your screen, you can filter hosts by the host name.
The Hosts tab provides the following information:
|Host||Name of the target host that you configured.|
|Agent Name||The name of the Collection Station or the Collection Agent provided while creating the host.|
Indicates whether redundancy is enabled or not for the Collection Station installed on the host.
|Version||The version of the Collection Station or Collection Agent used while creating the host.|
Displays whether the Collection Station (or Collection Agent) is connected or not, as follows:
|Host Tags||The tags assigned to the host.|
To add a host, on the Administration > Hosts tab, click Add Host, provide the following information, and click Create.
Enter the name of the target host from which you want to collect data.
You can also enter partial text, click Search, and select the appropriate host computers.
|Instance Name||(Optional) When you enter (or select) a host name in the preceding field, this field is automatically populated with the same information. You can manually override this value to provide a custom name by which you might want to identify the host.|
(Optional) Search for a Collection Host (Agent) by clicking Search Agentsor manually enter the Collection Host (Agent) name.
Note: If you specify a value in this field and create the host, then you cannot change this value while modifying the host.
(Optional) Select (or clear) this check box to enable (or disable) data collection for the particular Collection Agent.
(Optional) Search for an existing collection profile and click Select Collection Profilesto add it to the list of collection profiles that you want to associate with the host.
To override the values of macros associated with the collection profile, click Edit macrosunder the Actions column, specify new values next to the macro names and click Apply.
To remove the collection profiles from the list of collection profiles that you want to associate with the host, click Remove Profilesunder the Actions column.
|Host Level Tags|
|Select Tag name and corresponding value|
(Optional) Tags can be added while creating hosts and data collectors. However, if you assign tags while adding a host, then these tag details can be directly inherited while creating data collectors.
You can inherit tags while creating data collectors by selecting the target host and then selecting the Inherit Host Level Tags From Target Host check box under the tags section.
Tags can be added to categorize data collected, which can later be used to narrow down search results. Tags added or inherited while creating data collectors are displayed on the Search tab, under the Filters panel, and in the Tags section.
Example: If your are collecting data from hosts located at Houston, you can select a tag name for "Location" and in the value specify "Houston". While searching the data, you can use the tag, Location="Houston" to filter data and see results associated with the Houston location.
To be able to see tag names, you need to first add them by navigating to Administration > System settings.
To specify tag names and corresponding values, in the left box select a tag name and then type the corresponding tag value in the right box. While you type the value, you might see type-ahead suggestions based on values specified in the past. If you want to use one of the suggestions, click the suggestion. Click Add to add the tag name and corresponding value to the list of added tags that follow. Click Remove Tag to remove a tag.
Note: At a time, you can specify only one value for a tag name. To specify multiple values for the same tag name, each time you need to select the tag name, specify the corresponding value, and click Add.
For more information about tags, see Understanding fields.
|Host Level Group Access|
|Select All Groups||(Optional) Select this option if you want to select all user groups available. You can also manually select multiple user groups.|
You can use this setting to restrict user access to the data collected from this host. Before you enable this setting, you need to ensure that data access control is enabled at Administration > System Settings.
While creating data collectors, you can inherit the permissions enabled by using this setting, by selecting the Inherit Host Level Access Groups From Target Host check box.
In addition to using the UI, you can create host profiles in the following ways:
While creating a data collector, you need to specify details about the target host where data resides and details of the Agent that you want to use for collecting the data. Instead of manually specifying these inputs, you can store these details by creating a host profile. Then while creating the data collector, you can directly select the host.
Depending on whether you want to perform a local or remote collection, you can assign a host in the following ways:
Also, you can inherit host-level tags and group access permissions instead of manually assigning tags and user groups to the data collector. For more information, see Creating data collectors.
If you configure a Collection Agent by using ProactiveNet Central Monitoring Administration and the associated policy becomes disabled or is deleted, that Collection Agent is still displayed on the Hosts page and is not automatically deleted. In this scenario, you can manually delete the host with which the Collection Agent is associated.
(Optional) If you want to create a data collector that needs a customized data-pattern type, first create the data-pattern, and then create the data collector. For more information, see Setting up data patterns to extract fields.
