ManageEngine OpManager provides an effective network monitoring software that offers comprehensive fault and performance management across WAN and all other IT infrastructure. Using Network Monitoring Connector, an Applications Manager user can view the status of network devices in addition to servers, application servers, and databases monitored by Applications Manager.

**Key Benefits:**

1. Single console to monitor network, server & applications.
2. SLA and availability metrics of your business application by taking into consideration the network, servers, and applications.
3. Single console to view all alarms.

## Version Compatibility

| OpManager | Applications Manager |
|---|---|
| From 125483 onwards | From 15370 to latest |

## Configuring Applications Manager

Configure Applications Manager to obtain the data from OpManager.

1. In Applications Manager, go to **Settings → Add-on Settings**.
2. Click on the **Add** icon shown in the **OpManager** section. This will take you to the **OpManager integration** page.
3. Provide the details of the **server** and **port** in which OpManager is running. (Make sure that OpManager is up and running in this step.)
4. Provide the **REST API key** for user authentication, which is available in OpManager web client under **Quick links (Settings icon) → REST API Key**.
5. Check the **Enable Data Collection** option if you want to perform data collection for the network devices. By default, this option is enabled.
6. If you want to import all your devices from OpManager when integration is complete, then enable the **Import All Devices** option. (You also have the option to leave "Import All Devices" unchecked and associate the required devices to Monitor Groups after integration is complete.)
7. Click **Save**.

**Modifying the Poll Interval**

You can configure the poll interval and set the time when Applications Manager must check for updates from the External Connectors. Go to **Poll Interval** tab under **Add-on Settings**. The poll interval settings that you can modify are:

- **Update Alarms from External Connectors** — This option indicates the alarm update interval, in which the alarms from external connectors are updated in Applications Manager. This can be configured as per user requirements. The default time interval is 5 minutes.
- **Update All Devices and Alarms from External Connectors** — This option indicates the full update interval in which all the devices and alarms from external connectors are updated in Applications Manager. This can be configured as per user requirements. The default full update interval is 30 minutes.

**Associate network device Monitors into existing Monitor Groups:**

1. In order to associate OpManager monitor against a Monitor Group in Applications Manager, click on the **Home** tab.
2. Under **Monitor Group Information**, click **Associate Monitor** of Monitor Group Links in the left frame.
3. A list of discovered Monitors (for both Applications Manager and OpManager) that are available for associating and those that have already been associated with that Monitor Group is displayed. You will also see a list of network devices under **Network Devices** being displayed.
4. Select the check box of the corresponding Monitor from **Monitors not present in this Monitor Group** list and click **Associate**. You can also remove a Monitor which has already been associated with the Monitor Group by selecting the check box of Monitor(s) under **Monitors present in this Monitor Group** and clicking **Remove**.

**Associate network device Monitors into a new Monitor Groups:**

1. Click on the **New Monitor Group**.
2. Provide a Monitor Group name, description of that monitor group, and assign the owner for the monitor group.
3. Once the Monitor Group is created, click on **Associate Monitors** provided in the **Summary** tab of that Monitor Group.
4. A list of discovered Monitors (both Applications Manager and OpManager) that are available for associating is displayed. You will also see a list of network devices under **Network Devices** being displayed.
5. Select the check box of the corresponding Monitor from the list and click **Associate**.
6. Click on **Back to Monitor Group** to view the list of Monitors that you have associated for that group.

## Associating Alarms and Actions for Network devices

With the OpManager Network Monitoring Connector, you can view alarms from your OpManager network devices in Applications Manager and associate actions to OpManager attributes.

**Alarms:**

Once you have imported all your devices from OpManager, go to the **Alarms** tab to view all the alarms configured in Applications Manager along with their severity, type, date, and the technician to whom the alarm is assigned. You can sort through the alarms by clicking any column header in the table.

You can filter alarms by:

- **Severity** — Critical, Warning, or Clear
- **Time** — Last 30 minutes, 1 hour, 3 hours, 6 hours, 12 hours, 24 hours, Today, Yesterday, Last 7 days, Last 30 days, or a custom date range
- **Monitor Group** — Show alarms for a specific monitor group
- **Monitor Type** — Filter by a specific monitor type
- **Attribute Type** — Health, Availability, or Other Attributes

You can also perform bulk alarm actions such as annotating, executing actions, exporting to PDF/Excel, picking up alarms, or setting alarms as clear. Use the search functionality to find specific alarms by keyword. [Learn more about the Alarms tab.](https://www.manageengine.com/products/applications_manager/help/alarms.html)

**Actions:**

You can trigger corrective actions to OpManager attributes, once you have imported your network devices, such as sending e-mail, SMS, trap, and executing a command, to notify you of the alarms generated while monitoring the network devices. To trigger such corrective actions, you should have defined the action, which can then be associated with an attribute. [Click here to learn more about how to define actions.](https://www.manageengine.com/products/applications_manager/help/action-alarm-settings.html)

**Note:** You cannot create or associate thresholds for OpManager attributes.

## Limitations

If OpManager is integrated with the Central Server, integration in all the Probe Server will be restricted and vice versa.

If OpManager is integrated with both Central and Probe Server, OpManager's data collection in the Probe Servers will be disabled. No OpManager data from the Probe Servers will be displayed in both Central and Probe Server's UI. The user will be able to access the delete option for the Probe Server's OpManager. (**Note:** Integrating OpManager with both Central and Probe Server is not recommended.)

In the above case, if OpManager integrated with Central Server is deleted, then OpManager in Probe Server's data collection will be enabled and all the data related to Probe Server's OpManager will be displayed in both Central and Probe Server's UI.
