2===========
3
4        Job Monarch is a set of tools to monitor and optionally archive (batch)job information.
5
6        It is a addon for the Ganglia monitoring system and plugs in to a existing Ganglia setup.
7
8        To view a operational setup with Job Monarch, have a look here: http://ganglia.sara.nl/
9
10
11        Job Monarch stands for 'Job Monitoring and Archiving' tool and consists of three (3) components:
12
13        * jobmond
14
15                The Job Monitoring Daemon.
16                 
17                Gathers PBS/Torque batch statistics on jobs/nodes and submits them into
18                Ganglia's XML stream.
19
20                Through this daemon, users are able to view the PBS/Torque batch system and the
21                jobs/nodes that are in it (be it either running or queued).
22
23        * jobarchived (optionally)
24
25                The Job Archiving Daemon.
26
27                Listens to Ganglia's XML stream and archives the job and node statistics.
28                It stores the job statistics in a Postgres SQL database and the node statistics
29                in RRD files.
30               
31                Through this daemon, users are able to lookup a old/finished job
32                and view all it's statistics.
33
34                Optionally: You can either choose to use this daemon if your users have use for it.
35                As it can be a heavy application to run and not everyone may have a need for it.
36
37                - Multithreaded:        Will not miss any data regardless of (slow) storage
38
39                - Staged writing:       Spread load over bigger time periods
40
41                - High precision RRDs:  Allow for zooming on old periods with large precision
42
43                - Timeperiod RRDs:      Allow for smaller number of files while still keeping advantage
44                                        of small disk space
45               
46        * web
47
48                The Job Monarch web interface.
49
50                This interfaces with the jobmond data and (optionally) the jobarchived and presents the
51                data and graphs.
52
53                It does this in a similar layout/setup as Ganglia itself, so the navigation and usage is intuitive.
54
55                - Graphical usage:      Displays graphical cluster overview so you can see the cluster (job) state
56                                        in one view/image and additional pie chart with relevant information on your
57                                        current view
58
59                - Filters:              Ability to filter output to limit information displayed (usefull for those
60                                        clusters with 500+ jobs). This also filters the graphical overview images output
61                                        and pie chart so you only see the filter relevant data
62
63                - Archive:              When enabling jobarchived, users can go back as far as recorded in the database
64                                        or archived RRDs to find out what happened to a crashed or old job
65
66                - Zoom ability:         Users can zoom into a timepriod as small as the smallest grain of the RRDS
67                                        (typically up to 10 seconds) when a jobarchived is present

197START
198=====
199
200        * jobmond
201
202                The Job Monitor has to be run on a machine that is allowed to
203                query the PBS/Torque server.
204                Make sure that if you have 'acl_hosts' enabled on your PBS/Torque
205                server that jobmond's machine is in it.
206
207                1. Start the Job Monitor:
208
209                 > /usr/local/sbin/jobmond.py -c /etc/jobmond.conf
210
211        * jobarchived
212
213                1. Start the Job Archiver:
214
215                 > /usr/local/sbin/jobarchived.py -c /etc/jobarchived.conf
216
217        * web
218
219                Doesn't require you to (re)start anything.
220                ( make sure the Postgres database is running though )
