Displaying the Data in Shared Memory Collected by SAPOSCOL

You can use the dialog mode to call up the data that SAPOSCOL wrote to the shared memory. The most important command is dump, which is used to display various data collected by SAPOSCOL and stored in the shared memory, depending on parameters and options.

dump <Parameters> <option>

The following parameters are possible:

Parameter	Description
cpu	CPU
memory	Memory
top	Largest CPU user
disk	Hard disk
filesystem	File system
lan	LAN
proc	Monitoring of selected processes

The following options are possible:

Option	Description
single	Current value of a single selected parameter
all	Current value of all parameters available in shared memory
sum	Hourly averages for the last 24 hours of all parameters available in shared memory

Note

Note that not all of the parameters can be combined with all of the options.

There are also the following uses of the dump command:

Command	Description
dump config defined	Configured operating system parameters
dump config used	Currently used operating system parameters
dump hour	Displays a list of the last 24 hours; each of the 24 entries has the format hour: <0-23> of day <Number>, where <Number> specifies whether SAPOSCOL has consistent data for that hour: 0: No data available 1: current hour 2: inconsistent data <date (JJJJMMTT)>: Data available

Example

To display the memory-related operating system data in the shared memory, enter the following command at the Collector> command line:

dump memory all

The following information is displayed:

Collector> dump memory all
Pages paged in / sec         1
Pages paged out / sec        0

Controlling SAPOSCOL in Dialog Mode

You can control SAPOSCOL in dialog mode using the following commands at the Collector> input prompt:

Command	Description
detailson	Sets the details flag
detailsoff	Cancels the details flag
interval <n>	Changes the collection interval to <n> seconds (Default = 10)
leave	Deletes the shared memory
kill	Stops the background process
launch	Starts a new collector
force	Forces a new collector to start (only in emergencies)
status stat	Displays the status of the SAPOSCOL process that is collecting data in the background

The changed values are written to shared memory. SAPOSCOL reads these values directly before collecting data. The changes then take effect.

Note

If you change the collection interval, the collector switches to the new interval only after the expiration of the old interval.

Ending Dialog Mode

To leave the dialog mode of SAPOSCOL, use the command quit or the command exit.
