- oooovvvviiiieeeewwww displays the topology of an Origin server with performance
- information about CPUs, nodes and routers. The display is updated with
- new values retrieved from the target _h_o_s_t or _a_r_c_h_i_v_e every _i_n_t_e_r_v_a_l
- seconds (default is 2 seconds).
-
- oooovvvviiiieeeewwww behaves differently and produces different views for SGI 3000 and
- SGI 2000 systems. For SGI 3000 systems oooovvvviiiieeeewwww constructs the view
- configuration and launches ppppmmmmvvvviiiieeeewwww++++.... In the SGI 2000 case oooovvvviiiieeeewwww parses the
- command line and launches oooovvvviiiieeeewwww4444ssssnnnn0000....
-
- The rest of this document discusses the the first case, i.e displaying
- information about SGI 3000 systems. See oooovvvviiiieeeewwww4444ssssnnnn0000(1) for details about
- displaying data from SGI 2000 systems.
-
- oooovvvviiiieeeewwww generates a ppppmmmmvvvviiiieeeewwww++++(1) configuration file, and passes most command
- line options to ppppmmmmvvvviiiieeeewwww++++(1). Therefore, the command line options ----AAAA, ----aaaa,
- ----CCCC, ----hhhh, ----nnnn, ----OOOO, ----pppp, ----SSSS, ----tttt, ----TTTT, ----ZZZZ and ----zzzz, the _X_1_1-_a_r_g_s and user
- interface are described in the ppppmmmmvvvviiiieeeewwww++++(1) man page.
-
- oooovvvviiiieeeewwww can display the topology of SGI 3000 systems with up to eight
- routers, which covers systems with 1 to 128 CPUs. Configurations with
- metarouters and repeater routers are currently not supported.
-
- CCCCOOOOMMMMMMMMAAAANNNNDDDD LLLLIIIINNNNEEEE OOOOPPPPTTTTIIIIOOOONNNNSSSS
- There are two oooovvvviiiieeeewwww specific options. If ----VVVV is present, the
- configuration file is printed on the standard output and ppppmmmmvvvviiiieeeewwww++++ is nnnnooootttt
- executed. If ----wwww is present and an SGI 3000 system is being monitored,
- then the ``wait'' time is included for each processor (the default is to
- display only the ``user'' and ``system'' components of the CPU time).
- All other options are passed either to ppppmmmmvvvviiiieeeewwww++++(1) or to oooovvvviiiieeeewwww4444ssssnnnn0000(1).

- Routers are represented by oblong boxes with a colored indicator of the
- router's utilization on the top of the box. The color of the indicator
- has the following meaning:
-
- ccccyyyyaaaannnn insignificant router utilization
- 0 <= utilization < 1%
-
- lllliiiigggghhhhtttt ccccyyyyaaaannnn
- light router utilization
- 1% <= utilization < 5%

- medium router utilization
- 5% <= utilization < 20%
-
- oooorrrraaaannnnggggeeee
- high router utilization
- 20% <= utilization < 40%
-
- rrrreeeedddd saturated router utilization
- utilization >= 40%
-
- Nodes are represented by square boxes and CPUs are represented by a
- stacks of bbbblllluuuueeee, rrrreeeedddd and ccccyyyyaaaannnn colored blocks to show the uuuusssseeeerrrr, ssssyyyysssstttteeeemmmm and
- wwwwaaaaiiiitttt (if ----wwww specified) utilization of each CPU, respectively. The CPU
- stacks are grouped to appear on the top of the node they are physically
- connected to.
-
- Router ports are represented by cylindrical stacks, connected to the
- sides of a router box. The topology of the connection depends on the
- configuration of a machine. The router port stack shows the rrrreeeecccceeeeiiiivvvveeee
- bbbbyyyyppppaaaassssssss and the rrrreeeecccceeeeiiiivvvveeee qqqquuuueeeeuuuueeeedddd utilization on the per-port basis as vvvviiiioooolllleeeetttt
- and yyyyeeeelllllllloooowwww bands, respectively, which grow away from the router box as
- utilization increase. A grey cylinder adjacent to the colored bands, if
- visible, represents the unused bandwidth capacity.
-
- Unanimated ``pipes'' are used to join the endpoints for each router
- connection.
-
- To avoid cluttering the scene, especially for large configuration, CPUs
- and nodes may be omitted from the view. The ----llll option can be used to
- select the ``level of details'' as follows:
-
-
- 0000 Show only routers.
-
- 1111 Show routers and nodes.
-
- 2222 Show all the routers, nodes and CPUs. This is the default.

- The algorithm for 3-D layout of SGI 3000 system components by oooovvvviiiieeeewwww is
- complex, and relies on heuristics. If you encounter a configuration that

-
- pminfo -f hinv
-
- There are may be problems when oooovvvviiiieeeewwww cannot guess the information about
- routers connectivity in the non-standard SGI 3000 configuration. In this
- case router ports would be displayed but no attempt is made to draw the
- links between them.
