[221] | 1 | DESCRIPTION |
---|
| 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 | |
---|
[222] | 8 | To view a operational setup with Job Monarch, have a look here: http://ganglia.sara.nl/ |
---|
[221] | 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 | |
---|
[232] | 23 | * jobarchived (optionally) |
---|
[221] | 24 | |
---|
[232] | 25 | The Job Archiving Daemon. |
---|
[221] | 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. |
---|
[232] | 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 |
---|
[221] | 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 | |
---|
[232] | 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 |
---|
| 68 | |
---|

[222] | 200 | The Job Monitor has to be run on a machine that is allowed to |
---|
| 201 | query the PBS/Torque server. |
---|
| 202 | Make sure that if you have 'acl_hosts' enabled on your PBS/Torque |

| 203 | server that jobmond's machine is in it. |
---|
[221] | 204 | |
---|
[222] | 205 | 1. Start the Job Monitor: |
---|
| 206 | |
