The SNMP - QA Monitor is capable of monitoring various power management elements, such as output status, battery status, load level and capacity, on a Powerware xUPS UPS.
The Monitor's ability to retrieve and analyze data allows an Administrator to know when a power outage has occurred and stay aware of the remaining charge in the battery (or batteries). In order to extend the running time of necessary servers or components, critical decisions can be made using this information.
To implement the example outlined in this tutorial, you will need a Powerware xUPS UPS. For more information, please refer to Powerware's website and product documentation.

| Monitoring Condition | Pass if less than 30 Monitor failure indicates a problem with current being supplied to end devices. There may not be enough current presently being provided to attached devices. As a result, devices may not operate as expected. |
Monitor 4
| Monitor Name | Powerware xUPS :: Battery Capacity (%) |
| Monitor Type | SNMP - QA Monitor |
| SNMP Object Type | xupsBatCapacity |
| OID | 1.3.6.1.4.1.534.1.2.4.0 |
| Range | Integer (0..100) |
| Returns | Battery percent charge. |
| Monitoring Condition | Pass if greater than 85 Monitor failure indicates that the power failure is not an intermittent or temporary problem. Further action may be required. |
Monitor 5
| Monitor Name | Powerware xUPS :: Input Frequency (Line) |
| Monitor Type | SNMP - QA Monitor |
| SNMP Object Type | xupsInputFrequency |
| OID | 1.3.6.1.4.1.534.1.3.1.0 |
| Range | Integer (0..2147483647) |
| Returns | The utility line frequency in tenths of Hz. |
| Monitoring Condition | Pass if greater than 550 and less than 650 Monitor failure indicates that the power being supplied to devices is fluctuating. Devices may be susceptible to problems with receiving power at varying frequencies. |
Monitor 6
| Monitor Name | Powerware xUPS :: Output Load (% Capacity) |
| Monitor Type | SNMP - QA Monitor |
| SNMP Object Type | xupsOutputLoad |
| OID | 1.3.6.1.4.1.534.1.4.1.0 |
| Range | Integer (0..200) |
| Returns | The UPS output load, expressed as a percentage of rated capacity. |
| Monitoring Condition | Pass if less than 50 Monitor failure indicates that the percentage load attached to the UPS has been exceeded. The output load affects the running time of all components being supplied battery power. |
Monitor 7
| Monitor Name | Powerware xUPS :: Output Frequency |
| Monitor Type | SNMP - QA Monitor |
| SNMP Object Type | xupsOutputFrequency |
| OID | 1.3.6.1.4.1.534.1.4.2.0 |
| Range | Integer (0..2147483647) |
| Returns | The measured UPS output frequency in tenths of Hz. |
| Monitoring Condition | Pass if greater than 550 and less than 650 Monitor failure indicates that the power being supplied to devices is fluctuating. Devices may be susceptible to problems when receiving power at varying frequencies. Note: This configuration assumes that 60 Hz is nominal. Non-North American countries may have different nominal frequencies. As well, if your equipment is very sensitive, the range of acceptable values should be adjusted accordingly. |
Monitor 8
| Monitor Name | Powerware xUPS :: Output Source |
| Monitor Type | SNMP - QA Monitor |
| SNMP Object Type | xupsOutputSource |
| OID | 1.3.6.1.4.1.534.1.4.5.0 |
| Range | Integer (0..2147483647) |

1 = other Note: The enumeration 'none' (2) indicates that there is no source of output power (and therefore no output power); if for example, the system has opened the output breaker. |
| Monitoring Condition | Pass if not equal to 2 and not equal to 5 Monitor failure indicates that the UPS is not supplying line voltage to any attached devices. |
Monitor 9
| Monitor Name | Powerware xUPS :: Battery Status (ABM) |

| Monitoring Condition | Pass if equal to 4 Monitor failure indicates that the battery is not fully charged. |
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.
- Enter a unique, descriptive name for the Monitor in the Name field.
- Choose whether to automatically add the new Monitor to a particular Group.
- Check the Enabled checkbox.
- Choose whether you want the Monitor to Store Monitor Statistics for Recent Activity and Historical Reports.
- Specify the location of the SNMP agent (in this case, the Powerware xUPS UPS). Both IP Address and Domain Name are valid entries.
- If needed, specify a different Port Number for the SNMP agent. By default, the standard Port Number used for SNMP communication (Port 161) is already entered.
- 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.
- Enter the SNMP Community string that allows ipMonitor to communicate with the SNMP agent.
- 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 Powerware xUPS :: Battery Time Remaining 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.
- In order to return the desired value (the battery run time in seconds before the UPS turns off due to low battery), the SNMP - QA Monitor is configured to analyze the result as Numeric Data.
- The expected result is determined to be greater than (>) 600, ensuring that the Monitor will pass if the returned data indicates a number greater than 600 seconds (10 minutes).
|
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. |
