Overview

This module will manage Open XDMoD. This module works best when paired with Hiera for defining parameter values.

This module is designed so that different hosts can run the various components of Open XDMoD.

Open XDMoD Compatibility

• puppet-module-xdmod 2.x supports Open XDMoD 7.5.x
• puppet-module-xdmod 3.x supports Open XDMoD 8.0.x
• puppet-module-xdmod 4.x supports Open XDMoD 8.1.x
• puppet-module-xdmod 5.x supports Open XDMoD 8.5.x
• puppet-module-xdmod 6.x supports Open XDMoD 9.0.x
• puppet-module-xdmod 7.x supports Open XDMoD 9.5.x
• puppet-module-xdmod 8.x and 9.x supports Open XDMoD 10.0.x
• puppet-module-xdmod 10.x supports Open XDMoD 10.5.x

Optional Dependencies

When defining xdmod::ondemand::geoip_userid and xdmod::ondemand::geoip_licensekey the module trepasi/geoip is required.

Handling upgrades

This module does not support XDMOD upgrades. It's recommended to perform upgrades manually at this time.

XDMOD upgrades involve running the xdmod-upgrade command which does not lend itself to being handled by automation.

The general process with this module for upgrades is the following:

1. Upgrade all XDMOD packages
2. Run xdmod-upgrade
3. Run Puppet with a version and changes specific to new XDMOD version

Version 10.x upgrade notes

The mechanism to handle cron jobs was changed with 10.x of this module so that there is a single cron script that handles all the shreds and ingests. This change to cron jobs does not apply to appkernel/AKRR.

The single cron job is set using the xdmod::cron_times parameter. The following parameters are removed as related to cron jobs:

• xdmod::batch_export_cron_times
• xdmod::supremm_update_cron_times
• xdmod::ingest_jobscripts_cron_times
• xdmod::aggregate_supremm_cron_times
• xdmod::storage_cron_times

Usage

The XDMOD host needs to include the xdmod class:

include xdmod

Examples of some hiera values that may be useful to set globally

xdmod::version: '10.5.0'
# Disable roles that are enabled by default
xdmod::web: false
xdmod::database: false
# Define which features of XDMoD are enabled
xdmod::enable_appkernel: true
xdmod::enable_supremm: true
# Define site information
xdmod::organization_name: My Org
xdmod::organization_abbrev: MO
# Define resources
xdmod::resources:
  - resource: example
    name: Example
    resource_type_id: 1
    pi_column: account
    shared_jobs: true
xdmod::resource_specs:
  - resource: example
    processors: 12000
    nodes: 500
    ppn: 24
xdmod::supremm_resources:
  - resource: example
    resource_id: 1
    enabled: true
    datasource: pcp
    hardware:
      gpfs: /gpfs
    pcp_log_dir: /data/pcp-data/example
    batchscript:
      path: /data/job-scripts/example
# Set parameters used by multiple roles
xdmod::web_host: 'xdmod.domain'
xdmod::akrr_host: 'akrr.domain'
xdmod::database_password: 'xdmod-db-password-here'
xdmod::database_host: 'dbhost.domain'
xdmod::akrr_restapi_rw_password: 'some-password'
xdmod::akrr_restapi_ro_password: 'some-password'
xdmod::akrr_database_password: 'some-password'
xdmod::supremm_mongodb_password: 'some-password'
xdmod::supremm_mongodb_host: 'mongodb.domain'
xdmod::pcp_resource:
  - example
xdmod::cron_times:
  - 1
  - 0
# Ensure cron times are after the times scheduled to run app kernels
xdmod::akrr_ingestor_cron_times:
  - 0
  - 7
xdmod::appkernel_reports_manager_cron_times:
  - 0
  - 8

Example of how to enable OnDemand module:

xdmod::enable_ondemand: true
xdmod::resources:
  - resource: ondemand
    name: OnDemand
    resource_type: Gateway
    shred_directory: /path/to/ondemand/logs/directory
    hostname: https://ondemand.example.com
xdmod::ondemand::geoip_userid: 00001
xdmod::ondemand::geoip_licensekey: secret-key

Using Prometheus for SUPREMM job metric collection:

xdmod::supremm_cron_index_archives: false
xdmod::supremm_resources:
  - resource: example
    resource_id: 1
    enabled: true
    datasource: prometheus
    hardware:
      gpfs: /gpfs
    prom_host: prometheus.example.com:9090
    batchscript:
      path: /data/job-scripts/example

If you run a local yum repo for XDMoD packages

xdmod::local_repo_name: 'local-repo-name-here'

Enable Federated logins for XDMoD web host

xdmod::web: true
xdmod::manage_simplesamlphp: true
xdmod::simplesamlphp_config_source: 'puppet:///modules/site_xdmod/simplesamlphp/config.php'
xdmod::simplesamlphp_authsources_source: 'puppet:///modules/site_xdmod/simplesamlphp/authsources.php'

Run the XDMoD web interface and AKRR web service with SUPReMM support

xdmod::web: true
xdmod::akrr: true
xdmod::database: false
xdmod::enable_appkernel: true
xdmod::enable_supremm: true
xdmod::enable_update_check: false

Host the MySQL databases for XDMoD, AKRR and SUPReMM

xdmod::web: false
xdmod::database: true
xdmod::enable_appkernel: true
xdmod::enable_supremm: true

A compute node that will collect PCP data for SUPReMM. The xdmod::supremm::compute::pcp class will declare the pcp class by default. The metrics defined in pcp_static_metrics and pcp_standard_metrics will also define pcp::pmda resources based on which metrics are enabled. See xdmod::params for some defaults. The infiniband, perfevent, nvidia, gpfs, slurm, and mic metrics are commented out.

xdmod::web: false
xdmod::database: false
xdmod::compute: true
xdmod::pcp_static_metrics:
  - 'metrics that don't change often go here'
  - '#comments can be defined too and will be present in config file as comments'
  - 'more static metrics'
xdmod::pcp_standard_metrics:
  - 'metrics that change often like during a job'
  - '#comments can be defined too and will be present in config file as comments'
  - 'more standard metrics'

If you wish to use include style class declaration for the pcp class then the default pmlogger and pmie need to be removed and pmlogger_daily in cron needs to have modified arguments.

pcp::include_default_pmlogger: false
pcp::include_default_pmie: false
pcp::pmlogger_daily_args: '-M -k forever'
xdmod::web: false
xdmod::database: false
xdmod::compute: true
xdmod::pcp_declare_method: 'include'
xdmod::pcp_static_metrics:
  - 'metrics that don't change often go here'
  - '#comments can be defined too and will be present in config file as comments'
  - 'more static metrics'
xdmod::pcp_standard_metrics:
  - 'metrics that change often like during a job'
  - '#comments can be defined too and will be present in config file as comments'
  - 'more standard metrics'

A host that needs to run the SUPReMM job summarization.

xdmod::supremm: true

A MongoDB host needs to be setup for SUPReMM

xdmod::web: false
xdmod::database: false
xdmod::supremm_database: true
