Network Page
The Network page contains several charts.
To open the network page
- Select the Spotlight on Unix connection in the Spotlight Browser.

Charts on the Network page
Notes:
- Every chart has a legend (list of symbols) to its right that describes the various series (line graphs) on the chart.
- Click an item in the legend to highlight its series (line) in the chart. Click a second time to return the series to its normal appearance.
- Move the mouse pointer over an item in the legend to view the current value for that series within the chart.
| Chart | Description |
|---|---|
| Network Utilization |
The total rate of data traffic across all network cards (NICs) for the Unix host, measured in packets/second. Separate graphs on the chart indicate the rates at which data packets are being:
|
| Connections |
The number of external services with which the Unix host is communicating. The graphs on this chart represent three types of connections:
|
| Network Utilization by Kilobytes |
The total rate of data traffic across all network cards (NICs) for the Unix host, measured in kilobytes/second. Separate graphs on the chart indicate the rates at which data is being:
|
| Packets by Network Card |
This chart shows the rate of data traffic for every network card (NIC) in the Unix host, measured in packets/second. For every NIC, a separate graph represents the data packets:
|
| Error Rates by Network Card |
This chart shows error rates for the data transferred by every network card (NIC) in the Unix host, measured in errors/second. For every NIC, a separate graph represents the errors in data:
|
| Collisions by Network Card |
A collision is the result of two devices trying to transmit data packets across the network at the same time. The network detects the collision of the two transmitted packets as an error, and discards them both. Both devices then need to re-send the data. This chart shows the rate at which collisions occur for every network card (NIC) in the Unix host. |
Logins Page
The Logins page displays the users currently logged in to the selected connection.
To open the logins page
- Select the Spotlight on Unix connection in the Spotlight Browser.
-
Click Activity Summary | Logins.
Data in the Logins page
For each login, you can view the information that follows.
Note: Not all of the columns in the Logins table may be visible by default. To view hidden columns, right-click the grid heading and select Organize columns....
| Column | Description |
|---|---|
| UserName | The name of a user logged in to the Unix host. |
| Line | The terminal device associated with this connection. |
| LoginTime | The date and time when the user logged in for this session. |
| Idle | The time elapsed since the user's last activity (if available). |
| PID | The Process ID of the connection or login. |
| Comments | Additional information about the connection, including the address from which the connection was made (if available). |
Filesystems And Disk Information
The Filesystems drilldown displays information on the disk usage for each filesystem on the Unix system, and the proportion of disk space that has been used for each filesystem.
Note: Refer to man df(1) for further details on the values shown in the Filesystems page.
To open the Filesystems and Disk Information drilldown
- Select the Spotlight on Unix connection in the Spotlight Browser.
-
Click Filesystems.
To view disk usage in a chart
Right-click the Filesystems page and select View as Chart.
The information is displayed on a set of bar graphs that represent used and free disk space. Use the drop-down By Megabyte / By Percentage control to specify how to view disk usage.
To view disk usage in a table
Right-click the Filesystems page and select View as Grid.
| Column | Description |
|---|---|
| Filesystem | The Unix device that holds a filesystem. |
| Used Space | The amount of used space on the filesystem. |
| Free Space | The amount of free space on the filesystem. |
| Mounted On | The mount point for the filesystem. |
To view disk usage for NFS mounted disks
NFS (Network File System) was developed by Sun Microsystems to allow a Unix host to use disk space on a remote machine as if it were local storage. Spotlight provides a shortcut option to allow you to show or hide disk usage for NFS mounted disks.
Right-click the Filesystems page and select Show NFS mounted Filesystems.
Alarm Log
The Alarm Log drilldown displays information on the alarms associated with the selected connection.
To open the alarm log
- Select the Spotlight on Unix connection in the Spotlight Browser.
-
Click Alarm Log.
Notes:
- The Alarm Log drilldown is common to all Spotlight applications. See Spotlight Alarms for more information.
- The alarms are specific to the current Spotlight connection. Spotlight Alarms
