The scout Screen

· The banner line at the top of the screen displays the word scout, indicating that the program is running; it can display additional information if you include the following options:

- The -host option displays the name of the machine executing the scout program.

- The -basename option, if specified, displays the common DCE path name prefix of all File Server machines being monitored.

· The statistics display region comprises the majority of the window. In this region, scout displays the statistics gathered for each File Exporter; it displays each File Exporter on its own line. The area is divided into six columns, with the following labels and information:

· Conn: The number of open connections with principals. This column displays the number of connections that principals (users and machines) have open to the File Exporter. This number usually exceeds the number in the Ws column, which shows the number of active client machines, because each user on a machine can have several separate connections open at once and because one client machine can handle several users.

· Fetch: The number of fetches sent from client machines to the File Exporter. A fetch is an RPC requesting that the File Exporter send data. The statistic represents the number of fetches since the File Exporter started; it is reset to 0 (zero) whenever the File Exporter restarts.

· Store: The number of stores sent from client machines to the File Exporter. A store is an RPC requesting that the File Exporter store data. The statistic represents the number of stores since the File Exporter started; it is reset to 0 (zero) whenever the File Exporter restarts.

· Ws: The number of active client machines. This column shows the number of client machines that have communicated with the File Exporter in the last 15 minutes. This number is usually smaller than the value for Conn because a single client machine can have several connections open to one server.

· Server: The File Server machine name. This column contains the name of the File Server machine where the File Exporter is running. Names are shortened to display only the first 10 characters of the unique part of each machine name, which are the characters that follow the hosts element of a DCE path name. If two or more machines from different cells have a common name (for example, /.../abc.com/hosts/fs1 and /.../def.com/hosts/fs1), the name of each cell followed by a colon is displayed before the name of each machine (abc.com:fs1 and def.com:fs1). If the name of a File Server machine is too long for the width of the column, an * (asterisk) can appear in place of one or more characters in the name.

· Disk attn: The disk usage. This column displays the number of kilobyte blocks available on each DFS aggregate on the File Server machine. For example, a value of /dev/lv01:8949 indicates that the aggregate /dev/lv01 has 8949 kilobyte blocks free. If the window is not wide enough for all of the aggregate names, scout automatically creates subcolumns for the information. As with the names of server machines, if the name of an aggregate is too long for the width of the column, an * (asterisk) can appear in place of one or more characters in the name.

The label on this column indicates the threshold value at which entries become highlighted. By default, scout highlights the entry for any aggregate that is over 95% full. Therefore, the default label for this column appears as Disk attn:> 95% used.

For all columns except the Server column, you can use the -attention option to set a threshold at which entries in the column are highlighted. This notifies you that a certain value is exceeded. Disk attn is the only statistic with a preset default.

· The message/probe line at the bottom of the screen indicates how many times scout probed the File Exporters for statistics. By default, scout probes every 60 seconds; you can use the -frequency option to specify a different rate of time.
