Measures reported by NSIntrTest
Network interfaces in the NetScaler appliance are numbered in <slot>/<port> notation. By reading the statisitics polled in the syslog file, this test reports various numerical statistics relating to the states of the network interfaces such as started, stopped, hung etc. In addition, this test reports the number of times the network interface was reset and the number of times the network interface was bound/unbound to a channel.
For this test to run and report metrics, the NetScaler device should be configured to create a Syslog file in a remote Syslog server, where the details of all interactions with the NetScaler appliance will be logged.

Outputs of the test : One set of results for the NetScaler appliance being monitored
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| ni_stop_event |
Indicates the number of times the network interface was stopped. |
Number |
|
| ni_start_event |
Indicates the number of times the network interface was started. |
Number |
|
| ni_hung_state |
Indicates the number of times the network interface was in a hung state. |
Number |
|
| ni_restet_event |
Indicates the number of times the Network interface was reset. |
Number |
A network interface is reset if its settings are to be renegotiated. |
| intr_chnl_evnt |
Indicates the number of times the network interface was bound/unbound to a channel. |
Number |
Link aggregation combines data coming from multiple ports into a single high-speed link. Configuring link aggregation increases the capacity and availability of the communication channel between the NetScaler appliance and other connected devices. An aggregated link is also referred to as a “channel”.
When a network interface is bound to a channel, the channel parameters have precedence over the network interface parameters. (That is, the network interface parameters are ignored.)
A network interface can be bound only to one channel. |
| intr_throput |
Indicates the number of times the throughput of the network interface was less than the minimum required throughput. |
Number |
|
| nic_throput |
Indicates the number of times the throughput of the network interface is equal or greater than the miminum required throughput. |
Number |
|
| intr_power_on |
Indicates the number of times the network interface was powered on. |
Number |
|
| intr_power_off |
Indicates the number of times the netwotrk interface was powered off. |
Number |
