|
The Network panel shows the logins, connections and movement of data on the Unix system:
Logins
The number of users currently logged on to the machine you are diagnosing.
Connections
The number of external programs with which the machine is currently communicating. The types of connections are:
Established |
The total number of TCP/IP connections to this machine in the ESTABLISHED state. |
TIME_WAIT |
The total number of TCP/IP connections to this machine in the TIME_WAIT state, where the local socket has closed, and it is waiting for the remote end to signal that it has done the same. |
CLOSE_WAIT |
The total number of TCP/IP connections to this machine in the CLOSE_WAIT state, where the remote end of the connection has shut down, and it is waiting for the local end to do the same. |
NIC Bandwidth
Packets |
The rate of network packets being received and sent for the network card on this host that has the highest rate of packet transfers. |
Errors |
The rate of erroneous network packets being received and sent for the network card that has the highest rate of packet transfers. |
Packets |
If more than one network card is installed on this host, this is the rate of network packets being received and sent for the network card that has the second-highest rate of packet transfers. |
Errors |
If more than one network card is installed on this host, this is the rate of erroneous network packets being received and sent for the network card that has the second-highest rate of packet transfers. |
Data flows between the Network panel and CPU panel
Network (Network to CPU) |
Rate of incoming network data
The incoming rate of data to the server. Note: Spotlight contributes to the data traffic as part of its diagnostic activities. |
Network (CPU to Network) |
Rate of outgoing network data
The outgoing rate of data from the server. Note: Spotlight contributes to the data traffic as part of its diagnostic activities. |
Network Errors (Network to CPU) |
Rate of incoming network errors
The rate at which errors are received from the network. |
Network Errors (CPU to Network) |
Rate of outgoing network errors
The rate at which errors are sent from the machine to the network. | |

Disk Activity Panel
|
|
The Disk Activity panel shows information on disk usage:
Activity Guages
Activity Gauge (1) |
The percentage activity of the disk with the highest read/write rates. |
Activity Gauge (2) |
The percentage activity of the disk with the second-highest read/write rates. |
Least Space
/name |
By default, this is the mount point of the disk that has the least amount of free space, and that is not already 100% full. (Because of this, no CD-ROM devices are shown.)
You can configure this control to display the total and used space on ANY available disk on the system. To do so, right-click the control and choose Disk Options from the shortcut menu. |
Total |
The total amount of free space that has been allocated to this disk. |
Used (MB/GB) |
The amount of disk space that is currently being used by this disk. |
Used (%) |
The amount of disk space that is currently being used by this disk, expressed as a percentage. |
Data flows between the Memory panel and the Disk Activity panel
Disk I/O (Memory to Disk Activity) |
The number of writes that the system makes to disk per second. |
Disk I/O (Disk Activity to Memory) |
The number of reads that the system makes from disk per second. | |
