System management commands perform tasks on the node they are executing on. Performance Manager provides the following system management scripts. To execute one, from the main window's Execute menu choose System Management, then one of the following scripts:

CleanFilesystems

This script cleans full filesystems of core files and other user-specified unneeded files.

FileModification

This script determines if files have been modified or accessed.

GrowthOfFiles

This script determines if files are growing faster than a certain rate.

MaintainFiles

This script allows you to perform the following file management tasks:

• Move files to new filesystems
• Copy files to new filesystems or tapes
• Make symbolic links
• Delete files
• Change files' permissions
• Change files' user and group ownerships
• Undelete AdvFS files

TabularArchiver

This script allows you to capture all metric data on one or more nodes without having to monitor the nodes. The archived data can be replayed using Microsoft® Excel or any other graphing tool you create an interface for.

SignalProcess

This script sends the user-specified SIGNAL, in alphabetic or numeric form, to one or more processes. This script allows you to set the following flags:

• Signal a process directly by entering a process ID.
• Display all processes for a user and choose which to signal.
• Display all processes containing a given string and choose which to signal.

If only one process matches your entry when using the grep or user flag, it will be signaled directly.

DiskUsage

This script creates a report displaying the disk usage of each user on the file system specified. By default the display will be written to standard out. This script allows you to set the following optional flags:

• Mail the usage report to a user.
• Write the report to a file.

AddSwapFile

This script allows you to add a UFS partition as additional swap space. The script prompts you for a block special device (such as rz4c), creates an additional swap entry in /etc/fstab, and starts swapping to the newly created swap file.You will be asked to confirm items that alter your current system configuration. The script assumes that the disk is configured into the kernel, has a device special file, and that the in-memory disk label can be read.

Renice

This script alters the scheduling priority of one or more running processes. It allows you to do the following:

• Set the scheduling priority.
• Alter the priority of a process ID.
• Alter the priority of all processes for a given user
• Alter the priority of all processes for a given process group ID.

ProcessTree

This script parses the output of the UNIX ps command to give a tree of all processes with child processes tab indented underneath their parents.

filesize_thresh

This script makes an entry in cron to periodically check if a given file or directory has exceeded the specified threshold size. When a threshold is exceeded, mail will be sent to the address given with the -m flag and the cron entry will be removed automatically.

The interval is limited to: 1, 5,1 0, 15, 20, 30, 60 or time_of_day (hh:mm) in 24 hour format due to cron entry restrictions.

pm_fax

This script faxes a message created from the threshold environmental variables to the specified phone number. This script relies on a properly configured and functioning version of HylaFAX; see http://www.vix.com/hylafax/ for source distribution and build information. The script was tested with hylafax-v3.0pl1. This script relies on the hylafax environmental variables being set.

pm_mail

This script will mail a threshold message read from the threshold environmental variables to the user specified on the command line. If no user is specified the message will be mail to root.

pm_pager

This script will send a message based on the threshold environmental variables to the specified pager phone number. This script assumes that you have a properly configured and functioning version of HylaFAX; see http://www.vix.com/hylafax/ for source distribution and build information. The script was tested with hylafax-v3.0pl1. This script relies on the hylafax environmental variables being set. The pager of HylaFAX does not appear to work with the SkyPage service.

pm_shutdown

This script is a wrapper for the UNIX shutdown command that takes a list of machines that will be shut down simultaneously. If a message is not given, a default one will be included in the shutdown invocation.

pm_broadcast

This script is a wrapper for the UNIX rwall command. It writes a message to all users logged on the node(s) specified in the space separated node list.
