Changelog

[2.0.0] - 2023-09-11

Added

  • Add support for Prometheus as a performance data source. (#268)
  • Add 'datasource' field to output summarization record. (#269)
  • Add better support for the configuration check utility in supremmconf.py. (#263)
  • Add support for configurable job uniqueness. (#265)

Changed

  • Update from Python 2.7 to Python 3.6.
  • Update template paths to explicitly include the PCP version. (#255)
  • Use multithreaded archive indexing by default. (#250)

Fixed

  • Update indexing in plugins to use integer division when processing jobs with greater than 64 nodes. (#264)
  • Fix string encoding from byte array to UTF-8 for PCP on RHEL 8. (#261)

[1.4.1] - 2020-10-14

Fixed

  • Fix edge case where one type of corrupt performance counter value was not handled by the hardware performance counter plugin.
  • Fix bug in the job script ingestor that caused the script data in the database to be set to the string "0" if a script data was ingested more than once.

[1.4.0] - 2020-08-17

Added

  • Added new configuration setting that determines how the job script timestamps are interpreted. See https://supremm.xdmod.org/9.0/supremm-jobscript.html for details.
  • Added timeseries plot generation for Lustre filesystem data.
  • Added support for PBS style cgroups for CPU and memory metrics.

Changed

  • Improve error reporting when the temporary job directories cannot be created.
  • Improve the cpu performance counter plugin to report data on the available counters even if not all are present.
  • Update internal developer documentation
  • The supremm-setup script now requires mongo client 3 or later to run the mongo database setup (instructions for manual setup using the older client are at https://supremm.xdmod.org/9.0/supremm-processing-configuration.html#setup-mongodb)
  • Improve the job metadata handling in the developer test harness

Fixed

  • Update indexarchives.py to defer opening the connection to the XDMoD database until it it needed. This resolves an timeout issue when processing a large number of files or on a slow filesystem.

[1.3.0] - 2019-09-30

Added

  • Added IPMI power timeseries plugin that generates timeseries data from IPMI power measurements.
  • Add component tests for the performance counter plugins.

Changed

  • Updated RPM dependencies to match the official PCP version in RedHat/Centos 7.
  • Update the CI build to test against XDMoD version 8.1.
  • Improved support for hardware performance counters in the various performance counter plugins.

Fixed

  • Fixed bug in the performance counter preprocessor that caused it to incorrectly mark the performance counters as disabled by user.
  • Fixed incorrect unit in schema definition for the block device timeseries metric.

[1.2.0] - 2019-04-24

Added

  • Added GPU power plugin that summarizes the power usage for nvidia GPUs.
  • Added IPMI power plugin that summarizes the power usage from impi.
  • Added support for scanning the YYYY/MM/HOSTNAME/YYYY-MM-DD directory format for PCP archives.
  • Added --dry-run option to indexarchives.py script (used for testing purposes).

Changed

  • Removed deprecated code that supported python 2.6.
  • Updated templates to use the new recommended directory format.
  • Updated test harness to work with current plugins.
  • Database access code now sets the local_infile flag (needed for MySQL driver version 2.0.0 or later).

Fixed

  • Summarization script now only includes job start and end archives that are within 30 seconds of the job start and end. This mitigates a bug caused if the resource manager reuses the same job id for two different jobs.
  • The summarization software now skips corrupt PCP archives and will try to continue processing the valid archives. Previously processing would stop.
  • If a PCP archive has data missing at a timestep the framework will skip the timestep and continue processing the archive. Previously processing would stop.
  • The Slurm Proc preprocessor now filters non-unicode characters from command names.
  • Improvements to error handing in preprocessors and in the perfevent plugin.

[1.1.0] (2) - 2018-12-07

Fixed

  • Fix dependency list for the RPM build.

[1.1.0] - 2018-10-31

Added

  • Added support for XDMoD version 8.0.
  • Added --dry-run option to summarize_jobs.py script (used for testing purposes).
  • Added extra options to summarize_jobs.py to support more fine-grained selection of jobs to process
  • Added supremm-upgrade script to facilitate database migrations needed for a 1.0.5 to 1.1.0 upgrade.
  • Added multiprocessing support to indexarchives.py.
  • Added option to indexarchives.py to estimate the archive timestamp of job level archives from the filename. This dramatically improves the performance on parallel filesystems that have large number of files per directory.
  • Added plugin that detects periodic patterns in timeseries data.
  • Added GPU usage timeseries plugin.
  • Added AMD Interlagos support to the plugins that use hardware performance counters.
  • Added effective CPU usage metrics to the CPU usage plugin. This generates CPU usage statistics for the subset of CPUs that had any usage during a job.
  • Added summarize_mpi.py script that uses MPI for process management. This can be used on an HPC cluster to summarize jobs in parallel across multiple compute nodes.
  • Added ability to preprocess counter metrics that have < 64 bit range to 64 bit range counters.
  • Added ability to call the dynamic library version of pmlogextract. This mode of operation is intended to be used when running the summarization software as an MPI job on a compute resource that does not allow python-based MPI software to execute the fork() system call.

Changed

  • Updated PCP configuration templates.
  • Rewrote the main kernel of the summarization software in Cython. This improves the performance of the software.
  • Changed structure of the database tables that store PCP archive metadata. This improves the query performance.
  • Changed load balancing algorithm in multiprocessing mode to more evenly distribute work among processes.
  • Job summary documents now record the time when they were created.
  • Improved performance of the SlurmProc preprocessor.
  • Changed the process detection algorithm in SlurmProc to output processes in frequency order.

Fixed

  • Improved error handling for invalid data in PCP archives in several plugins (#172, #164, #135)
  • indexarchives.py script no longer exits if an unreadable file or directory is seen.
  • Job script parser now handles parsing PBS/Torque job array elements.
  • Improved error handling in summarize_jobs.py if the connection to the mysql server closes during processing.

Misc

  • Centos 6 and python 2.6 are no longer supported.

[1.0.5] - 2018-10-26

Fixed

  • Fix issue with the indexarchives script parsing PBS/Torque style job identifiers in PCP log filenames.

[1.0.4] - 2017-11-22

Fixed

  • Update to array indexing for compatibility with numpy >= 1.12.0

[1.0.3] - 2017-08-01

Changed

  • Updated text content of indexarchives debug message to clarify meaning of ignored archives.

Fixed

  • Fix issue with timeseries documents not being saved with the Centos 6 EPEL version of MongoDB (2.4). It is likely that this issue affects newer versions of MongoDB too.

[1.0.2] - 2017-01-26

Added

  • Added support for indexing archive directories with a YYYY/MM/DD format directory structure.
  • Added a file output setting for the outputter. This option is intended to be used for debug purposes.
  • Added a hardware inventory preprocessor that records the hardware information from the pcp archives.
  • Added support for per-node metrics for the CPU plugin.
  • Added support for per-node memory metrics.
  • Added support for load average metrics.

Changed

  • Indexing script defaults to ignoring archives that are less than 10 minutes old (based on filename). This reduces the likelyhood of the race condition where an archive exists but contains no data. The maxdate command line flag can be used to override this default.

Fixed

  • Removed spurious print to stdout in the MongoOutput class
  • Improve handling of missing data for the NFS timeseries plugin.
  • Improve handling of missing data for the Slurm cgroup memory plugin.
  • Fix errors in schema description and add missing metric documentation.
  • Allow the output configuration parameter type as a synonym for db_engine.

[1.0.1] - 2016-08-16

Added

  • Added interactive setup script that generates a configuration file and sets up the MySQL and MongoDB databases.
  • Added support for reading MongoDB settings from the XDMoD configuration file.
  • Added timeseries metrics for memory bandwidth, block device and total memory usage.
  • Added command line options to the archive indexer script to add limiting by max date and added ability to log debug messages to a file.

Changed

  • Changed the indexarchive script to use os.listdir() instead of os.walk(). This has a significant performance improvement when scanning files on filesystems that have slow stat() syscalls, such as parallel filesystems or network-attached storage.
  • Changed the name of the memory usage timeseries metric to make it clearer (now that the total memory usage metric has been added). Also improved the documentation of metric to clarify the datasource.

Fixed

  • The CPU plugin now sets the correct error code for short jobs that have insufficient CPU information. Previously the CPU metrics would report NaN.
  • Fix issue where the SIMD timeseries plugin would not correctly output data for the individual nodes and CPUs.
  • The SLURM process list plugin now limits the total number processes reported to 150. This mitigates an issue where jobs with a huge number of processes would result in a summary document that exceeds the MongoDB maximum document size.

[1.0.0] - 2016-05-23

Added

  • Support for Centos/RedHat 6 (with python 2.6).
  • Add support cgroup memory statistics for cgroups created by the Slurm cgroup plugin.
  • Add NFS metrics plugin.
  • Allow preprocessors to generate output that is included in the job summary.
  • Added support for PCP metrics that are strings.
  • Directory indexer now filters files based on directory name.
  • CPU timeseries plots now only include the cores that the job was assigned (if this information is available).

Changed

  • Configuration settings for MongoDB changed to allow connections to databases that require authentication.
  • Now uses the archives that are created at job prolog and epilog time to determine job time window.

Fixed

  • Fix error where the MySQL database driver settings were incorrectly being preserved between different calls to the getdbconnection() function.
  • Fix memory leak when pcp library calls threw exceptions.
  • Ensure description parameter in process() call always has correct indom information even if the indoms have changed during the archive.
  • Various error handling improvements for cases where the indom information is missing from a PCP archive or disappears from the archive during a job.
  • Improve robustness of Slurm cgroup extraction algorithm.

[0.9.0] - 2016-01-07

Beta version of the SUPReMM package. This is the initial prototype software for the summarization of SUPReMM data.
