-The code is structured into these files:
|
|
|
695b7d |
-
|
|
|
695b7d |
- virt_top_utils.mli / virt_top_utils.ml
|
|
|
695b7d |
-
|
|
|
695b7d |
- String functions and other small utility functions. This is
|
|
|
695b7d |
- included directly into virt_top.ml.
|
|
|
695b7d |
-
|
|
|
695b7d |
- virt_top_version.ml
|
|
|
695b7d |
-
|
|
|
695b7d |
- The version number (automatically generated by configure).
|

- virt_top.mli / virt_top.ml
|
|
|

|
|
|
695b7d |
- This is the virt-top program.
|
|
|
695b7d |
-
|
|
|
695b7d |
- The two interesting functions are called 'collect' and 'redraw'.
|
|
|
695b7d |
-
|
|
|
695b7d |
- 'collect' collects all the information about domains, etc.
|
|
|
695b7d |
-
|
|
|
695b7d |
- 'redraw' updates the display on each frame.
|
|
|
695b7d |
-
|
|
|
695b7d |
- Another interesting function is 'start_up' which handles all
|
|
|
695b7d |
- start-up stuff, eg. command line arguments, connecting to the
|
|
|
695b7d |
- hypervisor, enabling curses.
|
|
|
695b7d |
-
|
|
|
695b7d |
- The function 'main_loop' runs the main loop and has sub-functions
|
|
|
695b7d |
- to deal with keypresses, help screens and so on.

695b7d |
- virt_top_xml.ml
|
|
|
695b7d |
-
|
|
|
695b7d |
- Any code which needs the optional xml-light library goes
|
|
|
695b7d |
- in here. Mainly for parsing domain XML descriptions to get
|
|
|
695b7d |
- the list of block devices and network interfaces.
|
|
|
695b7d |
-
|
|
|
695b7d |
- The reason for having it in a separate file is so that we
|
|
|
695b7d |
- don't depend on xml-light.

695b7d |
- Any code which needs the optional ocaml-calendar library
|
|
|
695b7d |
- goes in here. This implements the --end-time command line
|
|
|
695b7d |
- option. Note there are two incompatible versions of the
|
|
|
695b7d |
- ocaml-calendar library, which is why we have two
|
|
|
695b7d |
- implementations. The Makefile works out which one to use.
