| <h1><a name="top">SLURM Accounting Storage Plugin API</a></h1> |
| |
| <h2> Overview</h2> |
| <p> This document describes SLURM Accounting Storage plugins and the API that |
| defines them. It is intended as a resource to programmers wishing to write |
| their own SLURM Job Accounting Storage plugins. This is version 1 of the API. |
| |
| <p>SLURM Accounting Storage plugins must conform to the |
| SLURM Plugin API with the following specifications: |
| |
| <p><span class="commandline">const char |
| plugin_name[]="<i>full text name</i>"</span> |
| <p style="margin-left:.2in"> |
| A free-formatted ASCII text string that identifies the plugin. |
| |
| <p><span class="commandline">const char |
| plugin_type[]="<i>major/minor</i>"</span><br> |
| <p style="margin-left:.2in"> |
| The major type must be "accounting_storage." |
| The minor type can be any suitable name |
| for the type of accounting package. We currently use |
| <ul> |
| <li><b>filetxt</b>—Information written to a text file. |
| <li><b>mysql</b>— Store information in a mysql database. |
| <li><b>pgsql</b>— Store information in a postgresql database. |
| <li><b>none</b>— Information is not stored anywhere. |
| </ul> |
| <p>The programmer is urged to study |
| <span class="commandline">src/plugins/accounting_storage/mysql</span> |
| for a sample implementation of a SLURM Accounting Storage plugin. |
| <p> The Accounting Storage plugin was written to be a interface |
| to storage data collected by the Job Accounting Gather plugin. When |
| adding a new database you may want to add common functions in a common |
| file in the src/database dir. Refer to src/database/mysql_common.c|.h for an |
| example so other plugins can also use that database type to write out |
| information. |

| |
| <h2>API Functions</h2> |
| |
| The Job Accounting Storage API uses hooks in the slurmctld. |
| |
| <p>All of the following functions are required. Functions which are not |
| implemented must be stubbed. |
| |
| <h4>Functions called by the accounting_storage plugin</h4> |
| |
