Spotlight on Unix

Use Spotlight on Unix to monitor Unix and Linux operating systems, detect and resolve problems.



Connect to Unix Systems Create / Modify / Delete connections to Unix systems.
Spotlight on Unix Home Page The Spotlight home page shows the flow of information and commands between various sub-components and the size and status of internal resources such as processes, disk files and memory structures.
Spotlight on Unix Alarms

Spotlight alerts you to problems with your system by issuing an alarm. You can configure Spotlight in the level of severity that constitutes an alarm, to disable an alarm, and the actions Spotlight takes on raising the alarm.

Spotlight on Unix Drilldowns When you have isolated a problem, you can display a drilldown page, whose charts and tables provide a detailed breakdown of the underlying statistics.


Configure the Unix System

To monitor a Unix system with Spotlight, ensure the Unix system is configured as follows.

Unix servers and versions.

Spotlight on Unix supports the following server operating systems:

  • Oracle Solaris 9, 10, 11
  • HP-UX 11i, 11i v2, 11i v3
  • IBM AIX 5.2, 5.3, 6.1, 7.1
  • Red Hat operating system based on Linux 2.4, 2.6 and 3.10 kernels
  • SUSE operating system based on Linux 2.4, 2.6 and 3.0 kernels
  • Oracle Enterprise Linux (OEL) based on Linux 2.4, 2.6 and 3.8 kernels

Unix programs.

Ensure the following Unix programs are accessible to the Unix login (through Spotlight):

  • Perl 5.x
  • awk
  • cat
  • date
  • df
  • grep
  • ifconfig
  • iostat (not HP-UX)
  • netstat
  • ps
  • sar
  • sed
  • tr
  • uname
  • uptime
  • vmstat
  • wc
  • who

For HP-UX, additionally

  • bdf
  • cstm
  • getconf
  • swapinfo
  • /usr/sbin/ioscan


For AIX, additionally

  • lsattr
  • lsdev
  • lsps
  • prtconf

For Solaris, additionally

  • /etc/swap
  • mpstat
  • nawk
  • prtconf

Unix User Permissions and Installation Settings

  • The Unix user should have no special processing on log-on. In particular there must be no input required from the user, and nor should any special login banners be displayed.
  • On AIX, the user must be a member of the "adm" group to be able to run the sar command.
  • On Linux, the sysstat package must be installed to enable the user to get detailed disk I/O information.
  • On Linux the /proc filesystem must be present.
  • For connection using SSH, the sshd daemon must be installed and running.

Remote Connectivity: SSH or REXEC

Spotlight on Unix will require you to select the connection type: SSH or REXEC. Information on SSH and REXEC is freely available on the Internet. We recommend SSH as password data is transmitted encrypted. REXEC does not encrypt password data.


  • Make sure the relevant SSH or REXEC daemon is running on the Unix machine and is configured to receive remote connections.
  • Commands to observe system activity (for example, netstat, vmstat, iostat, sar) must be accessible to REXEC / SSH sessions for Spotlight to observe Unix activity. Ensure these commands are located in the search path for REXEC / SSH sessions. If not, Spotlight will display an error.

Notes (Specific to SSH):

  • Spotlight supports both SSH1 and SSH2 protocols.
  • To allow Spotlight to make SSH connections to any Unix or Linux hosts that permit SSH connections, you may need to alter the PasswordAuthentication configuration item in the sshd_config file. Set the value of PasswordAuthentication to yes. Once you have modified the sshd_config file you must restart the sshd process to apply the new setting.
  • Public-key encryption is supported under SSH2 only. DSA and RSA are supported.

Note (Specific to REXEC): When Spotlight is monitoring a Unix operating system via REXEC with a valid user ID and password, remote commands may not work on the Unix host unless that user ID is added to the /etc/hosts.equiv file on the host.
