ESKM Memory Test

This test monitors the memory utilization of the HP Enterprise Security Key Manager (ESKM) security server and proactively alerts administrators to potential resource contention, if any.

Target of the test : A HP Enterprise Security Key Manager

Agent deploying the test : An external agent

Outputs of the test : One set of results for the target HP Enterprise Security Key Manager that is to be monitored.

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed.

Host

The host for which the test is to be configured.

SNMP Port

The port number through which the target router exposes its SNMP MIB; the default is 161.

SNMP Version

By default, the eG agent supports SNMP version 1. Accordingly, the default selection in the SNMP version 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.

SNMP Community

The SNMP community name that the test uses to communicate with the firewall. This parameter is specific to SNMP v1 and v2 only. Therefore, if the SNMP version chosen is v3, then this parameter will not appear.

User Name

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 the username parameter. 

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 this text box.  By default, this parameter is set to none.

Auth Pass

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

Confirm Password

Confirm the authpass by retyping it here.

Auth Type

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

Encrypt Flag

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

Encrypt Type

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

Encrypt Password

Specify the encryption password here.

Confirm Password

Confirm the encryption password by retyping it here.

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.

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.

Engine ID

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.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total memory

Indicates the total amount of memory allocated for the security server.

MB

 

Used memory

Indicates the amount of memory that is currently utilized by the security server.

MB

A value close to the Total memory measure indicates that the memory resources are depleting rapidly.

Free memory

Indicates the amount of memory that is currently available for use in the security server.

MB

A sudden decrease in this value could indicate an unexpected/sporadic spike in the memory utilization of the security server. A consistent decrease however could indicate a gradual, yet steady erosion of memory resources, and is hence a cause for concern.

Memory utilization

Indicates the percentage of memory that is utilized by the security server.

Percentage

If the value of this measure is close to 100%, it indicates that the memory utilization of the security server is at its peak. Therefore, the administrator may need to allocate additional memory resources to the security server.
