Overview of the Plug-In

The System Monitoring Plug-In for Oracle Exadata Storage Server extends Grid Control to add support for managing Oracle Exadata Storage Server targets. By deploying the plug-in to your Grid Control environment, you gain the following management features:

- Monitor Oracle Exadata Storage Server targets.

- Gather storage configuration and performance information of various Oracle Exadata Storage Server-related storage components such as Grid Disks, Cell Disks, and so on.

- Raise alerts and violations based on thresholds set on monitoring and configuration data.

- Provide rich out-of-box metrics and reports based on the gathered data. For more information, see "Viewing Metrics and Reports".

Versions Supported

This plug-in supports the following versions of products:

- Oracle Exadata Storage Server 11g Release 1 (11.1)

- Enterprise Manager Grid Control 10g Release 3 (10.2.0.3) or higher (Oracle Management Service and Oracle Management Agent)

Note:

If you want to use Enterprise Manager Grid Control 10g Release 3 (10.2.0.3) to monitor Oracle Exadata Storage Server targets, then apply the one-off patch 5844887 on Oracle Management Service (OMS) before deploying the plug-in.

- Oracle Management Agent 10g Release 3 (10.2.0.3) or higher

Prerequisites

The following prerequisites must be met before you can deploy the plug-in:

- Install Oracle Exadata Storage Server.

- Install Enterprise Manager Grid Control 10g Release 3 (10.2.0.3) or higher (both Oracle Management Service and Oracle Management Agent). You can use the Agent installed with this Grid Control to monitor the Oracle Exadata Storage Server targets.

- If you want to use an Agent that is different from the one installed with Grid Control, then install a separate Oracle Management Agent 10g Release 3 (10.2.0.3) or higher on a different computer.

- Establish SSH connectivity between Oracle Exadata Storage Server and the computer running the Agent. For information about setting up SSH connectivity, see "Setting Up SSH Connectivity".

Setting Up SSH Connectivity

To set up SSH connectivity between the computer where Agent is running and the Oracle Exadata Storage Server, do the following:

1. Log in to the computer where Agent is running, open a terminal, and run the following commands. (Ensure that you use a dedicated user account for accessing Oracle Exadata Storage Server data via SSH; if you do not have a dedicated user account, create one.)

1. Generate a pair of authentication keys:
cd ~/.ssh

ssh-keygen -t dsa -f id_dsa

2. Upload the public key (id_dsa.pub) to the home directory of the user celladmin on the Oracle Exadata Storage Server:
scp id_dsa.pub root@<cell_ipaddress>:/tmp

3. Login to Oracle Exadata Storage Server as root and change to its home directory:
ssh -l root <cell_ipaddress>

Add the contents of the id_dsa.pub file to the authorized_keys file in the .ssh directory of the user cellmonitor:

cat /tmp/id_dsa.pub >> ~cellmonitor/.ssh/authorized_keys

Make sure that the ~cellmonitor/.ssh directory has the permission 700 and ~cellmonitor/.ssh/authorized_keys file has permission 600:

chmod 700 ~cellmonitor/.ssh
chmod 600 ~cellmonitor/.ssh/authorized_keys

2. Open a new terminal and verify whether the SSH connectivity was successfully established:
ssh -l cellmonitor <cell_ipaddress> cellcli -e 'list cell detail'

If you are not prompted for any password, then you can assume that the connectivity is established.

If you are asked to confirm whether you want to continue connecting, specify Yes.

Deploying the Plug-In

After you ensure that the prerequisites are met, follow these steps to deploy the plug-in:

1. Download the archive file of the System Monitoring Plug-In for Oracle Exadata Storage Server to your desktop or computer on which the browser is launched. You can download the archive from Oracle Technology Network (OTN) or from the plugin_archives directory available on the product DVD.

2. Login to Enterprise Manager Grid Control as SYSMAN.

3. Click Setup from the upper-right-corner of the Grid Control Home page, then click Management Plug-ins from the left-side menu of the Setup page.
The Management Plug-Ins page appears (Figure 1).

The Add Oracle Exadata Storage Server page appears (Figure 2).

Figure 2 Add Oracle Exadata Storage Server Page

2. Provide the following information for the parameters:

- Cell IP Address 1 — Specify the IP address of the Oracle Exadata Storage Server. Ensure that the IP address is accessible (visible) from the computer where Management Agent is running.

- Cell IP Address 2 — If you have an Oracle Exadata Storage Server with multiple IP addresses for management and monitoring, then specify one of those IP addresses here. If you have only one IP address, then specify the same IP address that you specified for Cell IP Address 1. Ensure that the IP address is accessible (visible) from the computer where Management Agent is running.

- Agent Host Username — Specify the operating system user name of the computer where the Agent, which you want to use to monitor the Oracle Exadata Storage Server target, is running. This can be an Agent running on the same computer as OMS or an Agent running on a different computer. The user name you specify here must be the same user name you used to set up SSH connectivity.

- Agent Host Password — Specify the operating system password of the computer where the Agent, which you want to use to monitor the Oracle Exadata Storage Server target, is running. The password you specify here must be the password of the user you used to set up SSH connectivity.

3. Click Test Connection to make sure the parameters you entered are correct.

4. Reenter the encrypted parameters from step 2 if the connection test was successful, then click OK.

Note:

If you have added a backup Agent while deploying the plug-in, then you must repeat the steps outlined in this section to add the same Oracle Exadata Storage Server target to the backup Agent as well.

Creating Roles to Manage the Plug-In

For security reasons, Oracle recommends that the SYSMAN account be used only as a template to create other accounts, and not used directly.

Therefore to manage the plug-in, you need to create roles and administrators, and then assign roles to administrators. This restricts the privileges that each user has, for example deleting the plug-in or accessing reports.

Follow the steps provided in this section to provide management rights to users.

1. Log in to Enterprise Manager Grid Control as SYSMAN.

2. Click Setup.
The Setup page appears.

3. To create roles, click Roles. Click Help for assistance.

4. To create administrators, click Administrator. Click Help for assistance.

When the newly created administrator logs in, unlike SYSMAN, the administrator is restricted by the privileges set.

Example 1

Susan, the super administrator, wants to let Maria view the Oracle Exadata Storage Server target Exadata0526.

When Maria accesses the reports, if privileges are not set for Maria to view the Oracle Exadata Storage Server target, then the rows for Exadata0526 will not be displayed in the report. Therefore, for Maria to view Exadata0526, Susan has to set privileges as illustrated below:

1. Susan launches Enterprise Manager Grid Control and then in the Setup page, selects Roles.

2. She uses the Create Roles page to create a role for assigning to Maria.

3. In the Create Role Properties page, she specifies the name of the role as Maria_Role.

4. In the Create Role: Roles page, she chooses an existing role that can be applied to the role Maria_Role.

5. In the Create Roles System Privileges page, she chooses the system privileges for Maria.

6. In the Create Roles Targets page (Figure 3), she selects the target type Oracle Exadata Storage Server from the Type list to view all the Oracle Exadata Storage Server targets, and then selects test1 from the list of Available Targets.

Figure 3 Selecting Targets

7. In the Create Role Target Privileges page (Figure 4), she selects View privileges for the role, so that Maria (when assigned with this role) has the rights to view the Oracle Exadata Storage Server target.

Figure 4 Assigning View Privileges

8. In the Create Role Administrators page, she grants Maria the role.

9. In the Create Role Review page, she reviews the details and clicks Finish to end the process.

Verifying and Validating the Plug-in

After waiting for a few minutes for the plug-in to start collecting data, use the following steps to verify and validate that Grid Control is properly monitoring the plug-in:

1. In the Agent Home page, from the Monitored Targets table, click the Oracle Exadata Storage Server target link. The Oracle Exadata Storage Server Home page appears (Figure 5).

2. Verify that no metric collection errors are reported in the Metrics table.

3. Ensure that reports can be seen and no errors are reported by selecting the Reports property page.

4. Ensure that configuration data can be seen by clicking the View Configuration link in the Configuration section.
If configuration data does not immediately appear, click Refresh in the View Configuration page.

Note:

After you deploy and configure the plug-in to monitor one or more targets in the environment, you can customize the monitoring settings of the plug-in. This alters the collection intervals and threshold settings of the metrics to meet the particular needs of your environment. If you decide to disable one or more metric collections, this could impact the reports that the metric is a part of.

Setting Up Another (Backup) Agent for Monitoring

Instructions for configuring a high availability solution for the Exadata Storage cell or any other Exadata plug-in are documented in the Oracle Database Machine Monitoring Best Practices (Doc ID 1110675.1) document located in My Oracle Support.

Creating Oracle Exadata Storage Server Groups for Monitoring

Groups are an efficient and effective way to logically organize, manage, and monitor the components in your environment. Each group has its own group home page that shows the most important information for the group, and enables you to drill down for more information.

You can create a group for a set of Oracle Exadata Storage Server targets and monitor them as a single entity. This way, you can map your groups and targets with Realms and Cells, respectively.

To create a group:

1. Log in to Enterprise Manager Grid Control as SYSMAN.

2. Click Targets and then Groups.
Enterprise Manager Grid Control displays the Groups page.

3. In the Groups page, click Add.
Enterprise Manager Grid Control displays the Create Group wizard that has four tabs, mainly Members, Charts, Columns, and Dashboard.

4. In the Members page of the Create Group wizard, do the following:

1. In the top section, in the Name field, specify a name for the group you are creating.

2. In the Members section, click Add and select the Oracle Exadata Storage Server targets you want to add to this group.

3. In the Time Zone section, select an appropriate time zone.

5. In the Charts page of the Create Group wizard, specify the charts that you want to see for your group.

6. In the Columns page of the Create Group wizard, specify the columns and abbreviations you want to see in the Group Members page and also in the Dashboard provided in Enterprise Manager Grid Control.

7. In the Dashboard page of the Create Group wizard, specify the parameters you want to see in the Dashboard.

8. Click OK.
Enterprise Manager Grid Control displays the Groups page that shows the newly created group.

9. In the Groups page, click the group name to view details about that group.
Enterprise Manager Grid Control displays the Group Home page. You can access the other tabs, such as Charts, Administration, and Members to view more details. You can also click Launch Dashboard to view the dashboard.

For information about the elements used on the page and tasks that can be performed on each page, click Help from the top-right corner of the page.

Setting Up Alerts

Before you set up alerts in Grid Control, configure the Oracle Exadata Storage Server targets to send SNMP alerts to the Management Agent that is monitoring them.

To do so, run the following commands:

alter cell notificationPolicy=critical

alter cell notificationMethod=snmp

alter cell snmpSubscriber=((host=agenthostname,port=portno))

alter cell validate snmp

Note:

- If your host name contains characters other than alphabets and numbers, then ensure that you enclose the host name in single quotes. For example, if the host name is xyz001.server.com, then run the snmpSubscriber command as shown below:
alter cell snmpSubscriber=((host='xyz001.server.com',port=123))

- The SNMP receivelet listens on a single address and port for all monitored targets. The port is the UDP port with the same number as the TCP port used in the EMD_URL.
By default, the SNMP receivelet listens on all addresses; if the property SnmpRecvletListenNIC is set in emd.properties, the receivelet will attempt to resolve the value as either a name or IP address, and listen on only that address. (This parameter is independent of AgentListenOnAllNICs and EMD_URL because in some installations, the Agent may need to communicate with the OMS and with managed targets on different networks.

After configuring the Oracle Exadata Storage Server targets to send SNMP alerts, set up alerts in Grid Control. To do so:

1. Log in to Enterprise Manager Grid Control as SYSMAN.

2. Select Targets, then All Targets. The All Targets page appears.

3. In the All Targets page, from the Search list, select Oracle Exadata Storage Server and click Go. The page refreshes and lists only the Oracle Exadata Storage Server targets.

4. Click the Oracle Exadata Storage Server target you are interested in. The Oracle Exadata Storage Server Home page appears.

5. In the Oracle Exadata Storage Server Home page, from the Related Links section, click Metric and Policy Settings. The Metric and Policy Settings page appears (Figure 6).

Figure 6 Setting Up Alerts - Metric and Policy Settings Page

6. In the Metric and Policy Settings page, you can modify metric threshold values, edit monitoring settings for specific metrics, change metric collection schedules, and disable collection of a metric.
You can modify the thresholds directly in the table or click the edit icon (pencil icon) to access the Edit Advanced Settings page. For more information on the fields displayed in this page and how the thresholds can be modified, click Help from the top-right corner of this page.

Viewing Metrics and Reports
