The Collect tool gathers and displays information
for subsystems. You can set Collect to gather data
for a single subsystem or any combination of the following:
- process
- memory
- disk
- tape
- lsm
|
- network
- cpu
- tty
- filesystems
- message queue
|
Collect has two modes: collection and playback.
In collection mode, it gathers operating system and
process data and writes it to standard output, to
a binary file with a compressed format, or to both.
In playback mode, Collect reads from a previously
written binary file and writes to standard output.
The format of the data when written to standard output
is identical, whether during real-time collection
or playback mode.
With the Collect tool's live graphing feature,
you can also view the data in real time.
New for version 5.1
These features further enhance Collect's low system impact.
If you are running low on disk space, Collect will "sleep" until
you recover. And, if you do suffer a crash, you will still
have all the data from the most recent write interval.
