Docker Internal View

• Containers are ‘grouped processes’ isolated by Kernel Namespaces (PID, network, mount, …)

resource restrictions applicable through CGroups

• 1/2 Day, July 16th @ISC High Performance Deep dive into the talking points

How Docker might impact System Operations & HPC Applications

Further discussion beyond what I am talking about today

QNIBMonitoring

• Current monitoring systems do not connect overlaying metrics with log events

use/build inventory system to provide connections usually hidden

use/build inventory system to provide connections usually hidden

users perspective and scope/context/background

• QNIBMonitoring provides open metrics system (system / application metrics, log aggregates)

log event framework, consuming/processing/visualise events

auto discovery / configuration through consul

Cluster Use-Case

• Multiple backgrounds have to be considered Enduser (Engineer, Software Developer, Scientist)

Operation Personel

Management

• Psychology plays important role Local rationality / context

10.000ft Overview vs. verifying hypothesis vs. Reporting

Empower users to extend their domain knowledge by providing toolset

39

Context Sensitive Dashboards

• Small SLURM cluster couple of nodes, two user groups, couple of users

script & MPI workload

• Nodes are connected to Partitions

52

SLURM Inventar

• Nodes are connected to Partitions • Jobs are connected to both

53

SLURM Inventar

54

SLURM Dashboard

• Live progress of SLURM job Monitor iteration speed to estimate workload behaviour

Get to know job while it’s running (instead of postmortem)

Introduce application profiling / log events (enhance feedback)

55

Enduser Context




• Post Mortem Get detailed report after job has finished

56

Enduser Context




• Post Mortem Get detailed report after job has finished

• MDO jobs depending on outcome and progression submit next iteration(s)

• Live cluster Status USE method overviews (Utilisation/Saturation/Errors)

Anomaly detection (w/ and w/o humans)

Spotting abnormal behaviour

60

SysOps Context




• Drill into monitoring verify hypothesis about incidents/problems

correlate events, metrics and inventory
