PPC Battery Status Test

It is very important for administrators to know what is the current status of each and every battery if the system is running on battery power. This test monitors the battery and come up with key metrics like how much capacity is left, what si teh voltage and how long it will be before the battery would need replacement. These statistics help them ensure that the IT peripherals run uninterrupted and none of the device goes offline because of battery failure.

Target of the test : A PPC UPS

Agent deploying the test : An external agent

Outputs of the test : One set of results for the PPC UPS monitored .

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the target server that is being monitored.

SNMPPort

The port at which the monitored target exposes its SNMP MIB;

Data Over TCP

By default, in an IT environment, all data transmission occurs over UDP. Some environments however, may be specifically configured to offload a fraction of the data traffic – for instance, certain types of data traffic or traffic pertaining to specific components – to other protocols like TCP, so as to prevent UDP overloads. In such environments, you can instruct the eG agent to conduct the SNMP data traffic related to the monitored target over TCP (and not UDP). For this, set this flag to Yes. By default, this flag is set to No.

Timeout

Specify the duration (in seconds) within which the SNMP query executed by this test should time out in this text box. The default is 10 seconds.

SNMPVersion

By default, the eG agent supports SNMP version 1. Accordingly, the default selection in the SNMPversion list is v1. However, if a different SNMP framework is in use in your environment, say SNMP v2 or v3, then select the corresponding option from this list.

Context

This parameter appears only when v3 is selected as the SNMPVERSION. An SNMP context is a collection of management information accessible by an SNMP entity. An item of management information may exist in more than one context and an SNMP entity potentially has access to many contexts. A context is identified by the SNMPEngineID value of the entity hosting the management information (also called a contextEngineID) and a context name that identifies the specific context (also called a contextName). If the Username provided is associated with a context name, then the eG agent will be able to poll the MIB and collect metrics only if it is configured with the context name as well. In such cases therefore, specify the context name of the Username in the Context text box.  By default, this parameter is set to none.

Username

This parameter appears only when v3 is selected as the SNMPversion. SNMP version 3 (SNMPv3) is an extensible SNMP Framework which supplements the SNMPv2 Framework, by additionally supporting message security, access control, and remote SNMP configuration capabilities. To extract performance statistics from the MIB using the highly secure SNMP v3 protocol, the eG agent has to be configured with the required access privileges – in other words, the eG agent should connect to the MIB using the credentials of a user with access permissions to be MIB. Therefore, specify the name of such a user against this parameter. 

Authpass

Specify the password that corresponds to the above-mentioned Username. This parameter once again appears only if the SNMPversion selected is v3.

Confirm Password

Confirm the AuthPass by retyping it here.

AuthType

This parameter too appears only if v3 is selected as the SNMPversion. From the AuthType list box, choose the authentication algorithm using which SNMP v3 converts the specified username and password into a 32-bit format to ensure security of SNMP transactions. You can choose between the following options:

  • MD5 - Message Digest Algorithm
  • SHA - Secure Hash Algorithm
  • SHA224 - Secure Hash Algorithm 224 bit
  • SHA256 - Secure Hash Algorithm 256 bit
  • SHA384 - Secure Hash Algorithm 384 bit
  • SHA512 - Secure Hash Algorithm 512 bit

EncryptFlag

This flag appears only when v3 is selected as the SNMPversion. By default, the eG agent does not encrypt SNMP requests. Accordingly, the this flag is set to No by default. To ensure that SNMP requests sent by the eG agent are encrypted, select the Yes option. 

EncryptType

If the EncryptFlag is set to Yes, then you will have to mention the encryption type by selecting an option from the EncryptType list. SNMP v3 supports the following encryption types:

  • DES - Data Encryption Standard
  • 3DES - Triple Data Encryption Standard
  • AES - Advanced Encryption Standard
  • AES128 - Advanced Encryption Standard 128 bit
  • AES192 - Advanced Encryption Standard 192 bit
  • AES256 - Advanced Encryption Standard 256 bit

EngineId

This parameter appears only when v3 is selected as the SNMPVersion. Sometimes, the test may not report metrics when AES192 or AES256 is chosen as the Encryption type. To ensure that the test report metrics consistently, administrators need to set this flag to Yes. By default, this parameter is set to No.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test

Measurement

Description

Measurement Unit

Interpretation

Remaining battery capacity

Indicates the capacity remaining in the battery as a percentage of total capacity.

Percentage

Battery capacity goes down over time and any planning needs to he done on the basis of current capacity of the battery.

Battery voltage

Indicate the output voltage of the battery denoted in 1/10th of a Volt.

Volt

If the voltage is lower than expected, it may be a sign of poor battery performance which means the battery may need replacement sooner.

Battery temperature

Indicates the current internal temperature of UPS measured in 1/10th of a degree celcius.

Celcius

A high temperature may be a symptom of battery issue and can not just battery damage but also damage to internal wiring of the UPS.

Remaining battery runtime before exhaustion

Indicates the time it takes for the battery to go from current state to exhaustion.

Seconds

There should be enough time for you to make alternate arrangements if the battery is about to run out.

Battery replace indicator

Indicates if the batteries in the UPS needs replacement or not.

Boolean

The values reported by this measure and its numeric equivalent are mentioned in the table below:

Measure value Numeric Value
Battery needs replacing 0
Battery is fine 1

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current status of this fan. The graph of this measure, however, represents the status of the fan using the numeric equivalents only.

Battery current charge

Indicates the charge remaining in the battery as a percentage of maximum charge it can hold.

Percentage

If the charge is less, you may need to plan replacing or charging the battery.
