Content Service Usage Test
This test reports critical statistics indicating the current status and extent of usage of the content providing services on a Cisco CSS. As already mentioned, a service is a destination location where a piece of content resides physically (a local or remote server and port).
Target of the test : A Cisco CSS
Agent deploying the test : An external agent
Outputs of the test : One set of results for every service configured on the Cisco CSS.
Parameters | Description |
---|---|
Test period |
How often should the test be executed |
Host |
The IP address of the host for which this test is to be configured. |
SNMPPort |
The port at which the monitored target exposes its SNMP MIB; the default is 161. |
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. |
SNMPCommunity |
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 SNMPVersion chosen is v3, then this parameter will not appear. |
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. |
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. |
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:
|
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:
|
EncryptPassword |
Specify the encryption password here. |
Confirm Password |
Confirm the encryption password by retyping it here. |
Onlyup |
If this flag is set to Yes, then only the network interfaces that are operational - i.e. whose MIB-II operStatus variable has a value "up" - are monitored. If this flag is set to No, all network interfaces that have an adminStatus of "up" will be monitored. |
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. |
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. |
Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Service state |
Indicates the current state of this service. |
Number |
The value of this measure can be any one of the following:
|
Service enabled |
Indicates whether this service is currently enabled or not. |
Boolean |
The value 0 for this measure indicates that the service is disabled. The value 1 on the other hand implies that the service is enabled. |
Service avg min bandwidth |
Indicates the average minimum data sent through this service. |
Bytes |
|
Service total bandwidth |
Indicates the total data sent through this service. |
Bytes |
This measure is a good indicator of the network traffic generated through this service. |
Max service connections |
Indicates the maximum number of connections permissible to this service. |
Number |
|
Total service connections |
Indicates the total number of connections to this service during this measurement period. |
Number |
Ideally, this value should be less than the Max service connections measure. |
Average service load |
Indicates the number of content requests serviced by this service during this measurement period. |
Number |
This is a good indicator of the workload and content processing ability of the service. |
Service status |
Indicates the current status of this service. |
Number |
The value of this measure can be any one of the following:
