Built-in Capture Attributes
When an Agent sends an Agent Event in VMX-Analysis, it encodes in it a set of Capture Attributes.
The most important Attribute is Correlation ID, although this is not mandatory.
Attribute | Description |
|---|---|
Correlation ID | If supplied, VMX-Analysis uses it to correlate all of the related Agent Events in a Flow. If empty, then VMX-Analysis will use an alternative strategy for correlation. |
Agents also have a set of built-in Attributes, which are not editable but which can be used to aggregate data if required. These are:
Attribute | Description |
|---|---|
Flow | A tag that represents a Flow within the monitored system; for example, 'ORDERS' for the order flow, as opposed to the ‘PRICE’ flow. An Agent is specific to a single flow. If one Visibility Point in an application sees multiple flows, each Flow must have its own Agent(s) at that point. |
Subsystem | A tag that represents some sub-part of the application; for example, 'OM' for Order Manager. |
Location | A tag that represents some geographical location where the monitored component within the application; for example, 'LONDON'. |
Hostname | The physical host the related probe is running on, or for an external probe, the host being monitored. |
ProcessId | The identifier of the process in which the probe is running. |
Agents also have a set of custom Attributes, which are configured to meet requirement. Some examples:
Attribute | Description |
|---|---|
probename | A name, such as “NasdaqDecoder“, that is assigned to the probe and which is passed to the Agent to put into this Attribute. |
VLAN | A tag that provides information about the Virtual LAN. |
