OVIS-3.4.6

Changes in 3.4.6 since 3.4.4

FUNCTIONAL CHANGES:

• Added /usr/bin/ldms-static-test.sh and numerous test examples of ldms configuration in /usr/share/doc/ovis-ldms-3.4.6/examples/static-test. See man ldms-static-test. Includes store, sampler, and multilevel aggregation examples.

• Added dstat sampler for monitoring ldmsd itself. Expected use is to be
  loaded on aggregator and storage ldmsd instances. See Plugin_dstat man page.

• Added jobid collection support to lustre2_client sampler.

• Added opa2 sampler to collect omnipath hfi interface metrics. See Plugin_opa2 man page.

• Updated libgenders support for managing ports (see man ldms-attributes) in init scripts (see man ldms-attributes):
  ldmsd_use_unix_socket
  ldmsd_sockpath
  ldmsd_use_inet_socket
  ldmsd_config_port
  ldmsd_log
  ldmsd_vg
  ldmsd_vgargfile

• Added filters to trap and warn about common gender spelling and punctuation errors.

• Split the build/install of libgenders/boost tool from install of systemd scripts. Systemd scripts can be used without the ldmsctl_args3 tool if the user provides the daemon configuration commands in a named script listed in ldmsd.local.conf.

• Added missing man pages for samplers ported from LDMS v2: clock, procstat, sysclassib, jobid, lustre2_client, procsensors.

• New/updates to man, plugins for cray samplers aries_linkstatus, aries_mmr.

• Changed defaults in systemd scripts to allow more open files at aggregators and syslogid.

• Fixed overzealous failure condition handling in ldms_jobid.

• Added debug output of registered memory (mmalloc) in use at exit to better bound -m option value needed for ldmsd instances. New mm_stat call in lib/mmalloc supplies the data.

SECURITY CHANGES:

• Fixed default insecure (commonly know secret) ldmsauth file. Now it is invalid by default (too short).

RUNTIME CHANGES/BUG FIXES:

• Fixed C bugs in store related code:

  • idx_delete
  • notification (memory leak)
  • avl (attribute/value list handling of error conditions)
  • thread locking error in store_csv

• Fixed C bugs in network transports:

  • rdma connection resource leaks in error handling cases.

• Fixed C bugs in samplers:

  • jobid minor fixes
  • procnfs sampler now accounts for variations in nfs file layout. The procnfs sampler has never supported nfsv4 metrics and does not now.
  • Reduced repetitive logging of the same transient failure conditions.
  • Updated several samplers to run through transient disappearance of /proc.

HOUSEKEEPING CHANGES:

• Removed LDMS_BUILDTYPE from systemd control scripts (it was preventing relocatability, and is in any case obsolete).

• Remove most old packaging scripts from ldms source tree packaging/ directory.

• Change install permissions on pedigree script.

• Update rpath macro in build (deprecates some old apple os versions).

• Made rpms fully relocatable without forcing the user to manually set ld and zap related environment variables before invocation. This entails wrapping all the sbin/ldms binaries in .ldms-wrapper. Thanks to cray for assistance in this.

DEVELOPER CHANGES:

• Updated installed include files and /usr/lib/ovis-[ldms/lib]-configvars.sh so that 3rd party plugins can be built when only the installed ldms binaries and headers are used.

• Updated .gitignore settings.
