How the [assign itcm product name for the adsm variable] Works

The NI GigaStor captures all packets that are passively copied to it, for example, from a SPAN or mirror port, or from a network tap, and captures the entire packet for complete conversation analysis and reconstruction.

The [assign itcm product name for the adsm variable] on the NI GigaStor polls the management console for a list of server subnets, client networks, and port exclusions. While the packets are in memory on the NI GigaStor, and before they are written to disk, the [assign itcm product name for the adsm variable] copies matching TCP header data into packet digest files and sends the digest files to its assigned monitoring device. If necessary, you can assign a NI GigaStor to more than one monitoring device. We do not recommend assigning a NI GigaStor to the CA Application Delivery Analysis Manager.

The [assign itcm product name for the adsm variable] sends packet digest files to its assigned CA Standard Monitor or CA Multi-Port Monitor for processing and calculation of response time metrics for each application, server, and network combination. The [assign itcm product name for the adsm variable] does not calculate response time metrics.

The packet digest files are received by the NI GigaStor monitor feed on the monitoring device. The management console then evaluates the response time metrics from all monitoring devices to assign the best monitor feed to each server, and to monitor the busiest TCP applications on each server.

You can also define the applications you want the management console to monitor and load this configuration on the NI GigaStor.
