- [-disks <n>] [-nfs <n>] [-pids <n>]
- [-kernel <path>] [-fs_interval interval]

- [-bootup] [-syntax filename]
- [-aos filename]

- DESCRIPTION
- GlancePlus is a powerful and easy-to-use online performance diagnostic
- tool for HP-UX systems. It is distributed in two forms: "gpm", a
- Motif-based program and "glance", a character mode program. We
- provide both so you can choose the most appropriate tool for your job.
- With gpm, you get the power and ease-of-use of a Motif-based tool.
- With glance, you can run on almost any terminal or workstation, over a
- serial interface and relatively slow data communication links, and
- with lower resource requirements. Either component provides the same
- rich set of performance information.
- The default Process List screen provides general data on system
- resources and active processes. More specific data is presented via
- the CPU, Memory, Disk IO, Network, NFS, System Calls, Swap, and System
- Table screens. Specific per-process detail is also available via the
- individual process screens. Running in a terminal environment, Glance
- aids performance problem resolution on all HP 9000 series systems.
- Definitions and descriptions of each metric are provided in GlancePlus
- online help.
- Options
- -command This option can be used to request a different initial
- screen than the Process List screen. This startup
- option corresponds to the keystroke commands that
- display different detail screens once the tool is run.
- Only one of the commands in the first section of the
- COMMAND SUMMARY (below) is allowed for this option.
- -j interval This option allows you to preset the number of seconds
- between screen refreshes in place of the default value
- of 5 seconds. For example, if -j 60 is passed in, the
- - 1 - Formatted: June 20, 2006
- glance(1) HP-UX glance(1)
- screen update interval would be preset to 60 seconds.
- The allowable update value range is from 1 to 32767
- seconds.
- -nice nicevalue
- This option allows you to set the nice priority value
- for the glance process. The default nice value is -10
- (see man-page nice(1)).
- -nosort This option tells GlancePlus not to sort interesting
- processes listed on the Process List screen. This
- reduces Glance's CPU overhead.
- -lock This option allows Glance to lock itself into memory.
- (This is opposite of the meaning of earlier releases of
- GlancePlus). Note that response time may be enhanced
- by using this option, but there is the possibility that
- you will receive the error "Unable to allocate
- memory/swap space". If this happens, you must run
- GlancePlus without using this option.
- -p [dest] This option indicates that the continuous Print option
- should be enabled when the tool starts. This can be
- useful for printing screens automatically over a long
- interval. The output will be directed to the default
- lp device, unless the dest parameter is supplied. Once
- GlancePlus is running, another p command toggles the
- continuous print off.
- -f dest This option indicates that the continuous Print option
- should be enabled when the tool starts. This can be
- useful for printing screens automatically over a long
- interval. The output will be directed to the specified
- destination file. Once GlancePlus is running, another
- p command toggles the continuous print off.
- -maxpages numpages
- This option changes the maximum number of pages that
- can be printed with the p command. The default maximum
- is 200 pages.
- -disks <n>
- -nfs <n>
- -pids <n>

- -kernel <path>
- These command line options are passed directly into the
- midaemon and they control the midaemon's startup
- parameters (see man-page midaemon(1)). If the midaemon
- is already running, then these options are ignored.
- -fs_interval interval
- This option allows you to reset the number of seconds
- between updates of FS_SPACE_UTIL. Currently the default
- value for this metric is 4 minutes. The the minimum
- allowed update interval with this option is 30 seconds.
- -no_fkeys This option disables the display of function key
- labels.
- -adviser_off Allows you to run Glance without the Adviser.
- -adviser_only This option allows Glance to run with no screen
- displays to the terminal. Only the Adviser will run,
- sending it's output to stdout. With this option, the
- glance Adviser runs in the background, with stdout
- output optionally redirected to a file. If you want to
- run glance in "Adviser only" mode at startup time, you
- must include the -bootup option as well.
- -iterations count
- This option allows you to limit the number of intervals
- that Glance will run. This can be used in conjunction
- with the -adviser_only option which enables glance to
- run in the background with no terminal screen displays.
- Glance will execute for the number of iterations
- specified and then terminate. The minimum iteration
- value is 2 which will be used if the count is specified
- as 2 or less.
- -bootup Use this option along with -adviser_only when you want
- to run glance in "Adviser only" mode at startup time.
- -syntax filename
- Use this option to specify a file name which contains
- the syntax to be used by the Adviser. If no syntax
- file is specified, the Adviser will search for a user
- default file, ~/adviser.syntax. If no user syntax file
- is found, the system default syntax file,
- - 3 - Formatted: June 20, 2006
- glance(1) HP-UX glance(1)
- /var/opt/perf/adviser.syntax, will be used.
- -aos filename Use this option as an alternative to -adviser_only
- -syntax filename option.
- -all_trans This option allows glance to display all transactions
- registered on your system. If not specified, glance
- only displays transactions filtered by the values
- specified in your threshold file.
- -all_instances This option allows glance to display the most recent
- 2048 instances in a transaction. If not specified,
- glance only displays active instances with no stop
- time.

- EXAMPLES
- To choose the default start up options, which start glance in the
- Process List screen, updating statistics every five seconds, enter:
- glance
- To monitor system resource usage overnight, run glance, and print the
- screen once every hour until you return and exit the program, enter:
- glance -j 3600 -p
- To monitor and print swap utilization once every two hours, specifying
- the lp2 destination printer, enter:
- glance -j 7200 -p lp2 -w
- To execute glance at a higher than normal priority, limit the maximum
- number of pages output by the print command to 10, and request that
- the interesting processes be unsorted, enter:
- glance -nice -19 -maxpages 10 -nosort
- To run glance in the background against special adviser syntax,
- logging data to a file, you must first create a file that contains the
- appropriate adviser commands, then execute glance with stdout
- redirected to a file. For example:
- echo 'print gbl_stattime, " runq=", gbl_run_queue' >temp
- glance -aos ./temp -j 60>outfile &
