Pascal Robert 57.1 1 === Introduction ===
2
David Holt 137.1 3 wotaskd and JavaMonitor were open sourced when WebObjects 5.4 was released in 2007. In 2008 and 2009, the source was modified and included in Project Wonder. This is the list of additions that were added to the Wonder versions of the tools.

David Avendasora 77.1 8
David Avendasora 113.1 9 If you call [[http://monitorhost:port/cgi-bin/WebObjects/JavaMonitor.woa/wa/statistics]], the answer send you back statistics, in JSON format, about instances, per application. Sample :

David Avendasora 113.1 50 If JavaMonitor is configured with a password, and I hope you do, pass //pw=monitorpassword// as a argument to the query :
Pascal Robert 57.1 51
David Avendasora 113.1 52 [[http://monitorhost:port/cgi-bin/WebObjects/JavaMonitor.woa/wa/statistics?pw=monitorpassword]]
Pascal Robert 57.1 53
David Avendasora 121.1 54 === Direct Actions to many tasks ===
Pascal Robert 57.1 55
David Avendasora 113.1 56 You can do most of the standard tasks you do in Monitor by calling direct actions. They are in a different query handler, ///admin//. They follow the same format and use the same query parameters. Those DA can be useful if you need to restart instances or other tasks within ant or other build/deployment systems.
Pascal Robert 57.1 57
David Avendasora 113.1 58 //?type=all// : return details about all applications and instances
59 //?type=app&name=AppName// : return details about all instances of a specific application
60 //?type=ins&name=AppName-InstanceNo// : return details about one specific instance
61
David Avendasora 97.1 62 For example, if you want to get details about all instances and applications, you call :
Pascal Robert 57.1 63
David Avendasora 113.1 64 [[http://hostname:56789/cgi-bin/WebObjects/JavaMonitor.woa/admin/info?type=all]]
Pascal Robert 57.1 65
David Avendasora 113.1 66 To get details about the //AjaxExample// application :
Pascal Robert 57.1 67
David Avendasora 113.1 68 [[http://hostname:56789/cgi-bin/WebObjects/JavaMonitor.woa/admin/info?type=app&name=AjaxExample]]
Pascal Robert 57.1 69
David Avendasora 97.1 70 And for a specific instance :
Pascal Robert 57.1 71
David Avendasora 113.1 72 [[http://hostname:56789/cgi-bin/WebObjects/JavaMonitor.woa/admin/info?type=ins&name=AjaxExample-1]]
Pascal Robert 57.1 73
David Avendasora 113.1 74 The response for the direct actions will either send a JSON array or YES/NO. For example, the query //info// for all instances will return :

79
David Avendasora 113.1 80 {{/code}}
81
David Avendasora 105.1 82 List of available direct actions :
83
David Avendasora 113.1 84 ///info// : return details (number of deaths, state, etc.; see above), in JSON, about an instance.
85 ///running// : return YES if the instance is running, NO if not.
86 ///stopped// : return NO if the instance is running, YES if not.
87 ///bounce//: more on it later.
88 ///clearDeaths// : clear the number of deaths (same action as clicking the "Clear deaths" in JavaMonitor)
89 ///turnScheduledOn// : turn scheduling on for an application or instance. Call ///turnScheduledOff// to do the opposite.
90 ///turnRefuseNewSessionsOn// : turn "Refuse new sessions" on, call //turnRefuseNewSessionsOff// to do the opposite.
91 ///turnAutoRecoverOn// : guess what? It activate "Auto recover" And guess again? ///turnAutoRecoverOff// do the opposite
92 ///forceQuit// : force quit an application, might be useful to call it from a monitoring system.
93 ///stop// : stop an application/instance the normal way.
94 ///start// : start an application/instance the normal way.
David Avendasora 105.1 95
David Avendasora 121.1 96 === Automatic archive of SiteConfig.xml ===
David Avendasora 113.1 97
David Avendasora 121.1 98 On every change you do to the configuration, a backup of SiteConfig.xml will be done in, by default, /Library/WebObjects/Configuration.
99
100 === Bounce feature ===
101
102 In the "list instances" page, you get a "Bounce" action link. This action only work if you have at least one active instance and one inactive. What it does is :
103
104 * Find the inactive (eg : not started) instance and start it
105 * Find the active instances (minus the one started the step below) and enable "Refuse New Session"
106 * Bounce the active instances when the minimum session count is reached
107
108 This feature, from my understanding, allow you to upload new versions of your app, start up the new version and refuse sessions for the instances running on the older version. I don't know how this will work if your new version use migrations to change your schema (eg : old instances might raise exceptions because of database schema changes), so try it out on a test server before and put your results here.
109
110 === REST routes ===
111
David Avendasora 113.1 112 On September 28th 2010, REST routes were added in JavaMonitor. Those routes + the direct actions explained in this document allow you to control almost everything remotely (make sure that your JavaMonitor installation is secure). As the direct actions, append //?pw=XXXX// to the URLs if JavaMonitor is password protected.
113
David Avendasora 77.1 114 Examples of REST calls :

164 === Misc ===
165
166 The community's improved versions of **wotaskd.woa** and **JavaMonitor.woa** are now available as full Wonder applications. You can download them pre-built from the [[Hudson Wonder build server>>http://webobjects.mdimension.com/hudson/job/Wonder54/lastSuccessfulBuild/artifact/dist/]].
167
168 Alternatively you can build them from Wonder source and embed the frameworks or copy the frameworks into the //appserver// user home (on OS X 10.5, it's in ///var/empty//).
169
170 If you build everything from Wonder source, you can run :
171
172 {{code}}
173 ant deployment.tools -Dwonder.patch=54 -Ddeployment.standalone=true
174 {{/code}}
175
176 Please note that you have to build the Wonder before calling //ant deployment.tools//, if you get classpath errors when building the deployment tools, first run:
177
178 {{code}}
179 ant frameworks
180 {{/code}}
