Data Available to NEWS

NEWS processes a wide variety of data received from different sources and responds to the data it receives in an appropriate (user-definable) way. NEWS receives the following types of data:

• Unsolicited data
• Solicited data
• Response time data

NEWS also processes solicited and unsolicited data from the 3x74 Response Time Monitor.

Unsolicited Data

Unsolicited data—which originates from network nodes and distributed devices—received by NEWS includes the following:

• Traffic statistics
• Temporary and permanent error statistics
• Errors detected by network nodes
• Alert data generated by network components

Solicited Data

As a management application, NEWS can solicit data from network components by issuing requests using the CNM interface. The following types of data can be requested:

• Device-dependent error data
• Microcode level data
• Link error data recorded by network devices

Response Time Data

NEWS supports the 3x74 Response Time Monitor (RTM). This enables NEWS to receive response-time data, both solicited and unsolicited, that is maintained by the 3x74. The RTM data can be displayed in numeric or bar-graph format. NEWS also enables you to change the status of the RTM component in a 3x74. For instance, you can start or stop monitoring, or change the response time limits.
