sacct

sacct is a command-line utility in the Slurm Workload Manager designed to report accounting information for jobs and job steps. It queries Slurm's accounting database, typically maintained by the slurmdbd daemon, to provide historical data for completed work units. This makes sacct useful for auditing, performance analysis, and usage reporting.

The accounting data includes records for users, accounts, associations, partitions, and the resources consumed by each job and its steps. sacct can return per-job details such as JobID, JobName, User, Partition, AllocCPUS, TotalCPU, Elapsed, State, ExitCode, and memory usage metrics, as well as per-step data where available.

Output is highly configurable. Users can filter by time range (-S start, -E end), by job ID (-j), or by account or user, and select which fields to display with the --format option. Common flags include -P for parsable output and -n to omit headers. Examples are sacct -j 12345 --format=JobID,JobName,User,State,Elapsed,ExitCode and sacct -S 2024-01-01 -E 2024-01-31 -u alice --format=JobID,JobName,Partition,AllocCPUS,TotalCPU,Elapsed,State.

Relationship to other Slurm tools: sacct is the main reporting tool for accounting data and works alongside sacctmgr (account management) and sreport (summaries). Access to data depends on permissions and the Slurm configuration; typically users can see their own job records, while administrators can view broader accounting information. sacct requires that accounting is enabled and that the slurmdbd service is available and reachable.
