TCP port template
The TCP Port template lets you monitor the availability of an application that's accessible over TCP.
The application that is being tested can reside on any computer whether an agent for Operations Manager installed or not. Each watcher node must have an Operations Manager agent installed.
Scenarios
Use the TCP Port template in scenarios where applications rely on a service accessible over TCP. You can define each client as a watcher node. The monitors created by the template attempt to connect to the application from each client at the defined interval. The monitors verify that each client can connect successfully. In addition to validating the availability of the application itself, any network connections and other required features between the watcher node and the application are also validated.
Monitoring performed by the TCP port template
The monitoring performed by the monitors and rules created by the TCP Port template can include any of the following settings.
| Type | Description | Enabled? |
|---|---|---|
| Monitors | Target host reachable | Enabled |
| Connection accepted | Enabled | |
| Connection timeout | Enabled | |
| DNS resolution | Enabled | |
| Collection Rules | Connection time | Enabled |
Viewing monitoring data
All data collected by the TCP Port template is available in the TCP Port Checks State view located in the Synthetic Transaction folder. In this view, an object represents each of the watcher nodes. The state of each object represents the worst state of the set of TCP Port monitors running on that node. If one or more of the nodes is shown with an error while at least one other node is healthy, it could indicate a problem with that particular node accessing the specified computer, for example, a network issue. If all the nodes are unhealthy, it could indicate a problem with the application itself, either the computer being offline or the application not responding on the specified port.
You can view the state of the individual TCP Port monitors by opening the Operations Manager Health Explorer for each object. You can view performance data by opening the Performance view for each of these objects.
Wizard options
When you run the TCP Port template, you've to provide values for options in the following tables. Each table represents a single page in the wizard.
General Options
The following options are available on the General Options page of the wizard.
| Option | Description |
|---|---|
| Name | The name used for the template. This name is displayed in the Operations console. |
| Description | Optional description of the service. |
| Management Pack | Management pack to store the class and monitors that the template created. If you create any additional monitors or rules by using the service as a target class, you must store them in the same management pack.For more information about management packs, see Selecting a Management Pack File. |
Target and Port
The following options are available on the Target and Port page of the wizard.
| Option | Description |
|---|---|
| Computer or device name | The name of the computer or device to connect to. This can be a name or an IP address. It must be resolved by and accessible to each watcher node that you specify. |
| Port | The number of the port on which the application is listening. |
Watcher Nodes
The following options are available on the Watcher Nodes page of the wizard.
| Option | Description |
|---|---|
| Select one or more agent managed computers | Specify one or more computers to run the monitors and rules. For more information, see Watcher Nodes. |
| Run this query every | The frequency to attempt the connection to the specified computer and port. |
Creating and modifying TCP port templates
To run the TCP Port data source wizard
Start the Operations console with an account that has Author credentials in the management group.
Open the Authoring workspace.
In the Authoring navigation pane, right-click Management Pack Templates , and then select Add Monitoring Wizard.
On the Select Monitoring Type page, select TCP Port , and select Next.
On the General Properties page, in the Name and Description boxes, enter a name and an optional description.
Select a management pack in which to save the monitor, or select New to create a new management pack. For more information, see Selecting a Management Pack File.
Select Next.
In the Computer or device name box, enter the name or IP address of the computer or device to connect to.
In the Port box, enter the port number on which the application is listening.
Select Test to perform a test connection by using the connection string and query that you just provided.
Note
The test is performed on the workstation that you're using to run the template. If this workstation can't access the computer or device, this test fails. When the template is completed, the test is run from the watcher nodes that you specify.
Select Next when you've validated your connection.
Select one or more Watcher Nodes to run the monitor.
Specify the frequency to run the monitor in the Run this query box. Select Next.
Review the summary of the monitor, and select Create.
