	Using ipMonitor's SNMP - QA Monitor, Administrators can monitor power supplies on a Dell server to ensure they continue to provide a steady supply of electrical power to the system.
The SNMP - QA Monitor can be configured to monitor: The status of each individual power supply. The status of all power supplies in the Dell chassis.

Important! The sample Monitors defined throughout this tutorial assume that the Dell Server supports OIDs defined by MIB-Dell-10892. Monitors were tested against servers running DellOpenManage™ Server Administrator 1.6+.

	To incorporate the Dell MIBs described in this article into your ipMonitor installation, access the SNMP MIB Database Builder located within the ipMonitor Support Portal. Note: Custom databases are only available to registered customers. You must log in to access this section. 1. Expand the Enterprise branch, and place a checkmark beside Dell Computer Corporation. 2. Click the Construct MIB Database button located at the bottom of the page. Shortly after selecting your custom MIBs for creation, you will receive an email indicating that your database is ready for download. This email will contain a link to your personalized SNMP MIB database. Additionally, each visit to the Support Portal home page will also contain the link to your most recently created database.

Monitor 1

Monitor Name	Dell Diagnostic Service :: Combined Status - Power Supplies
Monitor Type	SNMP - QA Monitor
SNMP Object Type	systemStatePowerSupplyStatusCombined
OID	1.3.6.1.4.1.674.10892.1.200.10.1.9.1
Returns	This attribute defines the power supply status of all power supplies in this Dell chassis. The result is returned as a combined status value. 1 = other       the status of the object is not one of the following: 2 = unknown       the status of the object is unknown (not known or monitored) 3 = ok       the status of the object is ok 4 = nonCritical       the status of the object is warning, non-critical 5 = critical       the status of the object is critical (failure) 6 = nonRecoverable       the status of the object is non-recoverable (dead)
Monitoring Condition	Pass if equal to 3 Monitor failure indicates that the status of the power supplies in this Dell chassis is currently not 'ok'.

Monitor 2

Monitor Name	Dell Server :: Power Supply Status - #1
Monitor Type	SNMP - QA Monitor
SNMP Object Type	powerSupplyStatus.1
OID	1.3.6.1.4.1.674.10892.1.600.12.1.5.1.1
Returns	The status of the Dell power supply. 1 = other       the status of the object is not one of the following: 2 = unknown       the status of the object is unknown (not known or monitored) 3 = ok       the status of the object is ok 4 = nonCritical       the status of the object is warning, non-critical 5 = critical       the status of the object is critical (failure) 6 = nonRecoverable       the status of the object is non-recoverable (dead)
Monitoring Condition	Pass if equal to 3 Monitor failure indicates that the status of this power supply is currently not 'ok'.

Monitor 3

Monitor Name	Dell Server :: Power Supply Status - #2
Monitor Type	SNMP - QA Monitor
SNMP Object Type	powerSupplyStatus.2
OID	1.3.6.1.4.1.674.10892.1.600.12.1.5.1.2
Returns	The status of the Dell power supply. 1 = other       the status of the object is not one of the following: 2 = unknown       the status of the object is unknown (not known or monitored) 3 = ok       the status of the object is ok 4 = nonCritical       the status of the object is warning, non-critical 5 = critical       the status of the object is critical (failure) 6 = nonRecoverable       the status of the object is non-recoverable (dead)
Monitoring Condition	Pass if equal to 3 Monitor failure indicates that the status of this power supply is currently not 'ok'.

Note: All imported Monitors are initially disabled. This allows you to make changes to the default settings before the Monitors are enabled to go live in a production environment. Once the Monitors are imported, the following settings will need to be verified (and if necessary, modified) for each Monitor:

• IP Address
• UDP Port
• Community

To learn more about modifying the above parameters, please refer to the 'Configuring the SNMP - QA Monitor' section of this tutorial.

TIP For detailed instructions regarding importing XML files into your ipMonitor installation, please refer to the tutorial entitled "How to Import and Export Configuration Settings".

For the purposes of this tutorial, we'll be referring to the preconfigured Monitors included in the XML resource download. Alternatively, you can create a new Monitor by clicking the Monitors menu option and then selecting Add a Monitor. Choose the SNMP - QA Monitor from the Multi-Transaction / QA category.

1. Enter a unique, descriptive name for the Monitor in the Name field.
2. Choose whether to automatically add the new Monitor to a particular Group.
3. Check the Enabled checkbox.
4. Choose whether you want the Monitor to Store Monitor Statistics for Recent Activity and Historical Reports.

5. Specify the location of the Dell server. Both IP Address and Domain Name are valid entries.
6. If needed, specify a different UDP Port number. By default, the standard Port Number used for SNMP communication (Port 161) is already entered.
7. If you are using one of the preconfigured Monitors, the appropriate OID for the monitoring task is already entered. Otherwise, you will need to specify an OID path in the OID field.
8. Enter the SNMP Community string that allows ipMonitor to communicate with the SNMP Service.
9. Select the SNMP Version used by the device to be monitored. Both ipMonitor and the target device must use the same SNMP Version. Available options are: SNMP Version 1 and SNMP Version 2.

The following example uses the Analysis of Test Results settings configured for the Dell Server :: Power Supply Status - #1 Monitor provided in the XML resource download.

The type of data supported by the selected OID determines the possible methods of analysis using the SNMP - QA Monitor.

1. In order to return the desired value (the current status of the power supply), the SNMP - QA Monitor is configured to analyze the result as Numeric Data.
2. The expected result is determined to be equal to (==) 3, ensuring that the Monitor will pass if the power supply status is determined to be 'ok'.

TIP By default, the Timing Intervals for each parameter are set to 300 seconds. If needed, adjust these defaults to meet your specific monitoring environment's requirements until the optimum settings are reached.

For more information regarding the SNMP - QA Monitor, refer to the Monitors section of ipMonitor's Context-Sensitive Help system, and then select Monitor Types, followed by SNMP - QA. The Context-Sensitive Help can be accessed by clicking the Help link located in the top right corner of ipMonitor's Administration web interface.
