Overview

Enable SNMP monitoring in SCOM.

Environment

All DPA versions

Steps

DPA Setup:

In DPA > Options > Contacts and Contact Groups > Create SNMP Contact > fill out form with SCOM HOST IP and Port (usually 162).   Enter Community string that was set up on the SNMP Service on the SCOM Host.

Aplication Server, make sure the SNMP service is running and the Community string is set to the correct community string. In the above example, ‘public’ is the community string.  Note: this string is case sensitive.

SCOM Setup:

Listed below are the detailed steps in configuring a rudimentary SNMP-trap receiver to collect all messages sent from DPA alerts.

1. Configure OpsMgr as an SNMP Trap Receiver

On the SCOM Server, install the SNMP Service if not already installed.

  • In the Control Panel, select Add Remove Programs
  • Click on Add/Remove Windows Components
  • Scroll down and select Management and Monitoring Tools, click Details.
  • Click on the checkboxes for Simple Network Management Protocol and WMI SNMP Provider and click OK.
  • Click Next and click Finish.

Configure the SNMP Service on the SCOM server

  • Close Add or Remove Programs.
  • Click Start, Run, type services.msc, and then click Enter.
  • Scroll down and select SNMP Service. Right click the service and select Properties.
  • Select the Security tab.
  • Check the Send Authentication Traps checkbox. In the Accepted Community Names list, type “public” and click the Add to list button. Rights should be set to READ CREATE.
  • Select the Accept SNMP packets from any host option.
  • Restart the SNMP Service.

IMPORTANT: SNMP community strings are case sensitive!

2. Configure the DPA Server to communicate with the OpsMgr Mgmt Server (see DPA Setup)

The DPA server must be configured to accept SNMP requests from the Mgmt Server. You must also configure the DPA Server SNMP service to use the same SNMP community string you configured in the Accepted community names in the SNMP Service properties on your OpsMgr server.

3. In SCOM, configure one or more Alert-generating SNMP-Trap-based Rules

  • Create a unsealed management pack to store your SNMP-based monitoring rules.
  • In the Operations console, start the Create Rule Wizard.
  • On the Select a Rule Type page, do the following:
  • Expand Alert Generating Rules --> Event Based --> SNMP Trap (Alert).
  • Select your unsealed management pack from the list. Click Next.
  • On the Rule Name and Description page, do the following:
  • Type the Rule name, such as DPA Alert Collection Rule. Optionally, type a Description for the rule.
  • Click Select, then check the ‘select View all targets’ box, choose the SNMP Network Device, and then click OK.
  • Leave the ‘Rule is enabled’ selected to have the rule take affect at the completion of the wizard, or clear the check box to enable the rule at a later time, and then click Next.
  • On the Configure the trap OIDs to collect page, leave Use discovery community string selected.
  • Click to place the cursor in the Object Identifier Properties section and type the object identifier (OID) of each property of the network devices that you want to monitor, or select All Traps to monitor all targeted objects of the community, and then click Next.

Configure the DPA trap OID to collect (.1.3.6.1.4.1.22980) or select All Traps, which will raise an alert for any trap received from the Ignite server which you will discover with the Add Monitoring Wizard. You can also check the ‘use custom community string’ and enter the specific string.

  • On the Configure Alerts page, set the properties of the alert, for example:
  • Type the Name for the alert, such as Routers Traps Alert.
  • Optionally, type the Alert description. You can also click the (…) button and select Target and Data variables to include in the description, such as IP Address.
  • Select a Priority from the list, such as High.
  • Select a Severity from the list, such as Error.
  • Optionally, click Custom alert fields and type values, or click the (…) button and insert variables in the custom fields, and then click OK.
  • Optionally, click Alert suppression, and then select one or more Fields of the alert. Alert suppression is useful when there are multiple alerts for the same issue.
  • Click Create.

4. Discover the DPA Server in OpsMgr

  • In the Administration space, right click and launch the Discovery Wizard.
  • On the Auto or Advanced page, select Advanced discovery.
  • In the Computer & Device Types list, select Network Devices.
  • In the Management Server list, select the Management Server you will use to discover objects. Click Next.
  • On the Discovery Method page, enter the Start and End of the IP address range that you want to scan.
  • Type the SNMP community of the objects that you want to manage.
  • Click Discover to display the Discovery Progress page.

Discovery for even a single device will run for a couple of minutes by default. If you specify an IP range, it will take a little longer.

  • On the Select Objects to Manage page, select the Ignite server for management. Click Change.
  • On the Summary page, click Finish. The objects will display in the Network Devices node of the Operations Console Administration space.

At this point, SNMP-enabled device availability monitoring will start automatically.
