Revision as of 16:07, 21 March 2018

A number of samplers from v2 and v3 need updating or other change of status in v4 LDMS.

Here we catalog what's happening and any key rationale.

Fixed and tested

• everything under cray_system_sampler

• everything under aries_mmr

• dvs_sampler

• msr_interlagos

• meminfo

• array_example

• kgnilnd

• vmstat

• Procinterrupts - NOTE: This may want to be updated to use arrays

• procnetdev

• procnfs

• Procdiskstats - NOTE: Did not check the values

• Lnet_stats

Did, compiled, but cannot test

• procsensors [Ben to update base, longer term investigate configurability of data sources]

• Sysclassib - NOTE: this has warnings about use of a static var in an inline function

• Llnl/edac.c [Ben to update]

Various example or test samplers. Did, compiled, but cannot test

• All_example [BA]

• clock [BA]

• fptrans [BA]

• synthetic [BA]

Did, but cannot build

• Rapl

• Sampler_atasmart

• Perfevent – has warning about ioctl

Cannot do (or not applicable). Authors will have to do these. SEE NOTES WITHIN:

• Cray_power_sampler

• Generic_sampler

• Hadoop - should this be retired ?

• Hfclock

• Job_info

• Job_info_slurm

• Knc_sampler – all of these. I suggest we kill them

• Ldms_jobid – do we replace this with job_info?

• Lustre – note if lustre gets changed, will have to see if this affects the cray sampler, since it uses the lustre build.

• Papi – because I think this is getting replaced

• Power_sampler

• Procstat

• Switchx

• Test_sampler (this is a testsampler)

• Timer_base

• Tsampler

• Variable (this is a testsampler)
