The Manage Collectors options allow you to view a list of discovered Collectors, manage Collector connections, and configure Collector discovery rules. To view these options, select > . As shown in Figure 9. Collector Administration Options, the top of the page displays how many Collectors have been detected, how many total licenses your organization has purchased, and how many are still available for allocation.
One of the following discovery methods can be selected from the pull-down menu:
If Automatic Discovery is selected, FactFinder broadcasts a request for Collectors on UDP port 7561 at startup and again every 15 seconds. By default, only the local subnet is searched. Additional Collector discovery rules can be defined as described in Adding Collector Discovery Rules. FactFinder establishes a connection with machines with Collectors as they are discovered. If licenses are available, they are automatically licensed and set active.
Local subnet discovery broadcasts to UDP port 7561. If broadcast requests are not routed, Collectors on the local subnet may not be found. To find them, add a discovery rule for the local subnet or individual rules for each machine.
If Manual Discovery is selected, a button appears, and FactFinder stops searches for Collectors automatically. To search for Collectors based on the defined discovery rules, click the button. Any new Collectors within the discovery rules are added to FactFinder. Click the button to update the Collectors list if the newly found Collectors do not appear in the list.
Instead of the FactFinder Console finding the Collector, the Collector can be set to establish a connection to a specific FactFinder Console. This is useful to work around a firewall or if you don't want FactFinder sending out broadcast requests. Go to Configuring Collectors to Initiate Connection for details. If Collectors that initiate connection with FactFinder are not in the Collector list, click thebutton.
If a firewall exists between the FactFinder Console and the Collectors, be sure to open UDP and TCP port 7561 for Collector discovery. If the Collectors are configured to connect to a specific FactFinder Console instead, open TCP port 7560 so that Collectors can initiate the connection.
The Collector list is persistent. Once discovered, machines remain on the list even after its Discovery Rule is removed. Each time FactFinder is started, it attempts to connect to the current list of Collectors (displaying connection status in the Manage Collectors dialog) and then searches for additional Collectors according to the list of discovery rules. To remove a Collector from the list, deactivate it by unchecking the Active checkbox and uninstall the Collector from the machine so it does not respond to FactFinder.
Clicking on the Primary DNS Name for any machine listed opens a new App Explorer tab for the machine.
The Notes column can contain one of the following messages:
If a Collector stops responding to FactFinder (it is uninstalled, the Collector service is stopped, or the machine is rebooted), a Collector Disconnected event notification is shown in the Events Pane of related App Explorer views. Go to Events Pane for details.
By default, all Collectors found on the local subnet of the FactFinder Console are added to the Collectors list. To discover and display additional Collectors within a specific subnet or IP address range, click the Discovery Rules tab. The current set of discovery rules is shown as seen in Figure 10. Customize Collector Discovery Rules. Example rules are in the list by default but not set to active.
To define a specific machine or set of machines, click thebutton. You must provide a network address for the discovery rule. A port number must also be given. Accept the default of 7561 unless the Collectors are configured to listen to a different port for discovery. You can also enter a descriptive label for the rule.
Refer to Table 2. Collector Discovery Rules for a list of possible address definitions. Click Active column to deactivate the rule without deleting it.to add the rule to the list. Uncheck the
|IP address range||192.168.1.1-25|
|Entire class C subnet||192.168.1.*|
|Fully qualified domain name||server.example.com|
For IP address ranges, ranges only work within dot boundaries. For example, the
192.168.1.1-25 range is valid but
192.168.1.1 - 192.168.1.25 is not valid.
By default, FactFinder uses UDP and TCP port 7561 for Collector discovery. It is possible to use a different port for discovery or configure the Collector to refuse all discovery requests.
To use a different port for discovery:
For each Collector, modify the
BlueStripeCollector.properties file in the
config subdirectory of the Collector installation directory to match the desired port number:
To refuse all discovery requests from FactFinder, set the following in
By default, Collectors wait for FactFinder to discovery them and establish a connection. However, the Collector can be configured to contact a specific FactFinder and initiate communication. This is usually done over TCP port 7560.
To allow the Collectors to initiate connection instead of using automatic discovery:
On the machine with the Collector installed, modify the
BlueStripeCollector.properties file in the
config subdirectory of the installation directory:
collector.ff.connect=true collector.ff.host=factfinderhost.example.com collector.ff.port=7560
Only one host/port combination can be specified.
FactFinder.properties for the FactFinder Console, modify the port number as well:
This does not disable automatic discovery for the FactFinder Console. To disable automatic discovery, start FactFinder and select Automatic Discovery to Manual Discovery. The change takes effect immediately.> . Use the pull-down menu to change
The top of the Manage Collectors options shows how many Collector licenses are used and how many are available. Click the License Info tab of the FactFinder options to provide more details about your Collector licenses such as the location of the license file, the expiration date, and a copy of the license.
A machine without a Collector installed on it or a machine with an inactive Collector connection may still appear in the map and Machine List, but the data is limited to metrics interpreted from their interaction with machines with licensed Collectors. Performance graphs for machines without licensed Collectors have a gray background, indicating that the data is interpreted.
Collectors are equipped with a Rewind data recorder for storing data about the machine even when the FactFinder Console is not running. The data can then be retrieved using the History Mode or Snapshot feature of FactFinder. Rewind only collects data if the Collector is licensed. Deactivating a license for a Collector also deactivates its Rewind feature. Go to Rewind for details.
Another feature that only works with machines with licensed Collectors is the ability to create Alerts. Administrators can configure FactFinder to alert them when a defined threshold is exceeded for a variety of metrics. Refer to Alerts for additional information.
