Is here anybody having nice visualization of JobComp and JobacctGather
data in Grafana?
I save JobComp data in Elasticsearch, JobacctGather data in influxDB,
and thinking about how to provide meaningful insights to $users.
Things I'd like to show..: especially memory & cpu utilization, job
I use telegraf (which supports "exporter" output format as well) to
capture cgroupsv2 job data:
https://github.com/jose-d/telegraf-configs/tree/master/slurm-cgroupsv2
I had to rework it when changing from cgroupsv1 to cgroupsv2, as the
format/structure of textfiles changed a bit.

I think you need set reasonable "DefMemPerCPU" - otherwise jobs will
take all memory by default, and there is no remaining memory for the
second job.
We calculated DefMemPerCPU in such way, that the default allocated
memory of full node is slightly under half of total node memory. So

I feel that lot of slurm operators tend to not use 3rd party sources of
slurm binaries, as you do not have the build environment fully in your
hands.
But before making such a complex
I think installing/upgrading "slurm" rpm will replace this shared lib.
Indeed, as always, test it first at not-so-critical system, use vm
snapshots to be able to travel back in time ... as once you'll upgrade
DB schema (if part of upgrade) you AFAIK can not go back.

I see this question unanswered so far.. so I'll give you my 2 cents:
Quick check reveals that mentioned symbol is in libslurmfull.so :
[root@slurmserver2 ~]# nm -gD /usr/lib64/slurm/libslurmfull.so | grep
"slurm_conf$"
000d2c06 T free_slurm_conf
000d3345 T init_slurm_conf
Hi Dietmar;
I tried this on ${my cluster}, as I switched to cgroupsv2 quite recently..
I must say that on my setup it looks it works as expected, see the
grepped stdout from your reproducer below.
I use recent slurm 23.11.4 .
Wild guess.. Has your build machine bpt and dbus devel packages
From unclear reason "--wrap" was not part of my /repertoire/ so far.
thanks

What is the recommended way to run longer interactive job at your systems?
Our how-to includes starting screen at front-end node and running srun
with bash/zsh inside,
but that indeed brings dependency between login node (with screen) and
the compute node job.

Well you need Ethernet for OOB management (bmc/ipmi/ilo/whatever)
anyway.. or?

My impression is, that there are multiple challenges why it's not easy
to create good-for-all recent slurm RPM:
- NVML dependency - different sites use different NVML lib version with
varying update cycle
- pmi* deps - some sites (like mine) is using only one reasonable recent

To protect from HW failure, and to have more free hands when upgrading
underlying OS, we use virtualization with "live migration"/HA and

VM is easy to backup, restore as a snapshot, clone for possible tests, etc.

my users found the beauty of job arrays, and they tend to use it every
then and now.
Sometimes human factor steps in, and something is wrong in job array
specification, and cluster "works" on one failed array job after another.
Isn't there any way how to automatically stop/scancel/? job

we installed this: https://github.com/vpenso/prometheus-slurm-exporter

it's sent to influx (and shown by Grafana)

this is the reason.

you should not disclose munge.key to containers.

It is absolutely safe to restart slurmctld (and slurmdbd) with jobs
running on the cluster, that really is something that at least I do
all the time.
