Further +%% information on the placement algorithm can be found in +%% the place.erl file. +%% +%% +%% FILES +%% ----- +%% +%% The supervision tree graphical software consists of +%% the following files: +%% +%% appmon_a Gen server driving the process display window. +%% Responsible for assigning gs identifiers to all +%% processes and process link +%% appmon_a2 The process information gathering routines. +%% Works by following the process links from application +%% master once every second +%% dg The process database is implemented as a shared +%% digraph (see manual pages for digraph) and this is +%% the routines handling this digraph. Since the digraph +%% is shared appmon_a2 will put some info into it that the +%% appmon_a later will modify. The structures used are +%% described in dg.hrl +%% place Places a tree, decides the x and y coordinates (not +%% necessarily corresponding to window coordinates) of +%% processes (or vertices to be specific). Note that +%% special routines are used to transform the possibly +%% cyclic digraph into a strict tree before trying to +%% place it. +%% +%% +%% +%% IMPLEMENTATION DETAIL +%% --------------------- +%% +%% The appmon_a module will follow links between processes, +%% starting with the application master. A unique +%% reference is used to prevent infinite recursion. Note +%% that this process and link gathering is done in the +%% live digraph so that already known processes are +%% updated with the reference and new ones are added to +%% the digraph. After all processes and links have been +%% added or updated a search is made for those processes +%% and links that have an old reference. These are those +%% processes and links that are not present in the +%% application any more. Those are extracted from the +%% digraph and then deleted and the extracts are then +%% used (by appmon_a) to delete the appropriate gs +%% objects. The responsibilities of appmon_a is thus 1) add +%% all new processes and links to the digraph and 2) make +%% a list of all those objects from the digraph that have +%% been deleted. +%% +%% When appmon_a2 has gathered all necessary information it +%% notifies the appmon_a display manager. Note that this is +%% implemented as a call (as opposed to a cast) to +%% prevent appmon_a2 from changing the digraph while appmon_a +%% uses it. appmon_a places all processes using the place +%% module. place will place the processes in the x y +%% planes, hopefully in a nice way, re-forming the +%% digraph during the process into a strict tree using +%% some simple heuristics, some links that makes the +%% graph cyclic will be considered secondary and later +%% coloured red. Note that the process links are not +%% placed since their coordinates are those of the +%% processes that they are links between. The place +%% module is only concerned at a fairly high level of +%% abstraction. Currently its x coordinates are used as +%% real coordinates while the y coordinates must be +%% scaled to correct values, thus the x plane is +%% continous and the y plane is disctrete. +%% +%% Having placed processes the new ones are drawn on the +%% display along with all new process links, then all +%% processes and process links are moved to their +%% possibly new positions. The place module is not +%% sensitive to changes in position and therefore has no +%% concept of which nodes will have to be moved. hence +%% all nodes are moved (but most of them probably to the +%% same position as before) +%% +%% +%% +%% +%%---------------------------------------------------------------------- + + + +-export([start/2, start/3, stop/0]). + + +-record(astate, {app, name, client, digraph}). + +-import(lists, [foreach/2]). + +%% gen server stuff +-behaviour(gen_server). +-export([init/1, handle_cast/2, handle_info/2, terminate/2]). +-export([handle_call/3, code_change/3]). + + +-define(APPSPACE, 10). % The space between apps +-define(NODEAREA_H, 90). % The height of a node +-define(BUTTAREA_H, 80). % The button area height +-define(APPBUTT_H, 20). % Height of appl button +-define(EDITORW, 260). + +-define(MAXWIDTH, 800). +-define(MINWIDTH, 382). +-define(MAXHEIGHT, 450). +-define(MINHEIGHT, 325). + +-define(SUPVIEWTXT, "Sup. view"). +-define(PROCVIEWTXT, "Proc. view"). +-define(CLOSETXT, "Close"). +-define(REFRESHTXT, "Refresh"). +-define(SAVEOPTSTXT, "Save options"). +-define(HELPTXT, "Help"). + +-define(CHARWIDTH, 7). %Should use GS primitives + +-define( darkkhaki, {189, 183, 107}). +-define( palegoldenrod, {238, 232, 170}). +-define( peachpuff4, {139, 119, 101}). +-define( red, red). +-define( darkgrey, {169, 169, 169}). +-define( lightgrey, {211, 211, 211}). +-define( royalblue, {65, 105, 225}). +-define( aquamarine4, {69, 139, 116}). +-define( palegreen4, {84, 139, 84}). +-define( darkseagreen, {105, 139, 105}). +-define( f_line_col, {150, 150, 255}). + + +-include("appmon_dg.hrl"). + + +%%------------------------------------------------------------ +%%------------------------------------------------------------ + + +start(NodeName, AppName) -> + gen_server:start_link(?MODULE, {NodeName, AppName, AppName}, []). + +start(NodeName, AppName, AppId) -> + gen_server:start_link(?MODULE, {NodeName, AppName, AppId}, []). + + +stop() -> + ok. + + + +%%------------------------------------------------------------ +%% Public interface + + +%%------------------------------------------------------------ +%% Administration + +%% AppName is the name of the application, usually an atom like sasl +%% or kernel, AppId is the application pid or the application name, +%% either goes. +init({NodeName, AppName, AppId}) -> + process_flag(trap_exit, true), + {ok, Client} = appmon_info:start_link(NodeName, self(), []), + init_ref(), + init_foreign_places(), + DG = digraph:new([cyclic, private]), + State = #astate{app=AppId, name=AppName, client=Client, digraph=DG}, + refresh(State), + setup_base_win(NodeName, AppName), + {ok, State}. + +terminate(_Reason, _State) -> + ok. + +code_change(_OldVsn, State, _Extra) -> + {ok, State}. + +handle_call(norequest, _From, State) -> + {reply, null, State}. + +%%------------------------------------------------------------ +%% handle casts + +handle_cast({ping, _Node, _From}, State) -> + {noreply, State};

The idea is that several tools +%% could use this module for their core information gathering +%% services. +%% +%% The module is based on the notion of tasks. Each task should +%% have a nice public interface function which should handle task +%% administration. Tasks are identified by a "key" consisting of +%% three items, the requesting pid, the name of the task and the +%% task auxillary parameter. The requesting pid is the pid of the +%% callee (in the appmon case it can be the node window for +%% instance), the task name is whatever name the task is given +%% (in the appmon case it can be app, app_ctrl or load). The task +%% name can be seen as the type of the task. The task auxillary +%% parameter is an all purpose parameter that have a different +%% meaning for each type of task so in appmon the Aux for app +%% contains the root pid of the monitored application and in +%% app_ctrl it contains the node name (just to distinguish from +%% the other app_ctrl tasks, if any) while the Aux parameter is +%% not used for the load task at all. +%% +%% Each task also carries a list of options for +%% customisation. The options valid for a task is completely +%% internal to that task type except for the timeout option which +%% is used by do_work to determine the interval at which to +%% perform the task. The timeout option may also have the value +%% at_most_once that indicates that the task should not be done +%% more than once, in appmon the remote port (or process) info +%% (pinfo) task is such a task that is only done once for each +%% call. Note that the only way to change or update options is to +%% call the public interface function for the task, this will +%% merge the old options with the new ones and also force the +%% task to be executed. +%% +%% All tasks are managed by the do_work function. The basic +%% functionality being that the result of the task is compared to +%% the previous result and a delivery is sent to the callee if +%% they differ. Most tasks are then done on a regular basis using +%% the timer module for a delay. +%% +%% There are a limited number of places where the module need to +%% be updated when new services are added, they are all marked +%% with "Maintenance Note", and here is a quick guide: +%% +%% First implement the task. Put the functions in this module +%% among the other task implementations. Currently all task +%% implementations should be put in this file to make it simple +%% to monitor a node, this module should be the only one +%% needed. Then add your implementation to the do_work2 function +%% and finally add a public interface function among the other +%% public interface functions. Voila. +%% +%% +%% +%% Future ideas: +%% +%% Appmon should maybe be enhanced to show all processes on a +%% node. First put all processes in an ets P, then pick those +%% that belong to applications (the normal way), then try to find +%% those processes that are roots in process link trees and pick +%% them.

Two +%% things can make a node not be placed at the left +%% margin and that is the case when a previous node has +%% been placed at the same vertical level as the node we +%% are trying to place (thus forcing a placement further +%% to the right), and the second case is when the middle +%% of the subtree of the node is not at the left margin +%% (which it only is when the subtree is empty).
