How to configure tango-monitor-gmoc for GMOC reporting

Introduction

This page explains how to install and configure the tango-monitor-gmoc package for shared GENI operational monitoring, on any supported operating system. The tango-monitor-gmoc package is the base package for reporting data to GMOC, and should be a dependency for any aggregate-specific software which reports data to GMOC.

This page was written for:

tango-monitor-gmoc-1.2.12-1

and may not work well with earlier versions. We have tested these instructions on Ubuntu 10.04 only, but expect they will also work on CentOS. If you are running a different OS and it is not obvious how to translate the instructions, please contact GPO infra.

Compatibility note: gmoc.py, the GMOC monitoring client, requires python2.6 or later. If the default python on your system is earlier than 2.6, you'll need to install a secondary python. GPO infra has done this for CentOS 5, and can provide suggestions.

Upgrading from previous versions

This is the first packaged version of tango-monitor-gmoc, so there are no upgrades from previous versions.

Variables

  • <cronuser>: The user as which to run GMOC monitoring. The scripts can run as root, or as a non-root user of your choice. (At GPO, we use the ganglia user.)
  • You need several pieces of identifying information for your site:
    • <submission_user>: a one-word phrase describing your site, which is your username for data submission to GMOC (see step I) (e.g. ExoGENI-BBN)
    • <organization>: a one-word name for the organization which runs the aggregates which are reporting (e.g. ExoGENI)
    • <pop>: a one-word name for the physical location where your aggregates sit (e.g. gpolab)

When you work with GMOC to configure monitoring data submission in step I, you will need to provide them a few pieces of metadata about your organization and POP, which they will request.

Steps to configure monitoring submission

I. Prepare to submit authenticated monitoring data to GMOC

You need to do these steps if you are installing monitoring for the first time.

  1. IF you have not yet registered your site to submit data to GMOC, generate a password for automated monitoring data submission to use. All resources managed by a given set of people use the same credential; you only need to do this step once for your entire site. Note: the password you use for your site registration is a new password generated for the purpose of submitting monitoring data. Do not reuse any existing passwords from your site.
  1. Store your site password in a file which monitoring can use. (The password file location is configurable, but use the default unless you have a reason to do something different):
    sudo touch /usr/local/etc/monitoring_passwd
    sudo chown <cronuser> /usr/local/etc/monitoring_passwd
    sudo chmod 600 /usr/local/etc/monitoring_passwd
    sudo vi /usr/local/etc/monitoring_passwd
    
    Add exactly one line to this file, containing the monitoring password you want to use for the user <submission_user>.
  1. Register site credentials: IF you have not yet registered your site to submit data to GMOC, follow the instructions at GENIMetaOps/SiteCredentials.

II. Install the monitoring software

Do these steps every time you install or upgrade tango-monitor-gmoc.

If you are installing on Ubuntu

  1. Download the tango-monitor-gmoc_1.2.12-1_all.deb package file from http://software.geni.net/local-sw/, and copy it onto your reporting host, e.g. into ~/tango-monitor-gmoc_1.2.12-1_all.deb.
  1. Use dpkg to install the local package. This may fail due to dependencies and say it is leaving the package "unconfigured". Therefore, invoke apt-get to fix any missing dependencies:
    sudo dpkg -i ~/tango-monitor-gmoc_1.2.12-1_all.deb
    sudo apt-get -f install
    
    WARNING: If you are upgrading this package as a dependency of tango-monitor-foam, please note that a file moved from tango-monitor-foam-0.4 to tango-monitor-gmoc. Therefore, you must upgrade tango-monitor-foam at the same time you install tango-monitor-gmoc. This invocation should work:
    sudo dpkg -i ~/tango-monitor-gmoc_1.2.12-1_all.deb ~/tango-monitor-foam_0.5.0-1_all.deb
    
    If you are installing tango-monitor software for the first time, this will not affect you.

If you are installing on CentOS

  1. Download the tango-monitor-gmoc-1.2.12-1.noarch.rpm package file from http://software.geni.net/local-sw/, and copy it onto your FOAM host, e.g. into ~/tango-monitor-gmoc-1.2.12-1.noarch.rpm.
  1. Use yum localinstall to install the local package. This will install the provided file, using your standard yum repositories to find any dependencies:
    sudo yum --nogpgcheck localinstall ~/tango-monitor-gmoc-1.2.12-1.noarch.rpm
    

III. Create required directories and files

  • <submission_user>: a one-word phrase describing your site, which is your username for data submission to GMOC (see step I) (e.g. ExoGENI-BBN)
  • <organization>: a one-word name for the organization which runs your FOAM (e.g. ExoGENI)
  • <pop>: a one-word name for the physical location where your FOAM sits (e.g. gpolab)

These steps need to be done the first time you install tango-monitor-gmoc-1.2.12-1 or later.

  1. Populate the gmoc_monitoring configuration file:
    • Create the config file (the file does not contain sensitive information, and may safely be left world-readable):
      /usr/local/etc/gmoc_monitoring.conf
      
    • Edit the file and make sure to populate all variables:
      $ cat /usr/local/etc/gmoc_monitoring.conf
      
      # GMOC short name which is your username for authenticated monitoring data submission
      SITENAME=<submission_user>
      
      # GMOC short name of organization which manages your aggregate (may be the same as SITENAME if appropriate)
      ORGNAME=<organization>
      
      # GMOC short name of "POP"/lab where your aggregate is located (may be the same as SITENAME if appropriate)
      POPNAME=<pop>
      
  1. Create a directory for tango-monitor scripts to store state:
    sudo mkdir -p /var/spool/rrds/REPORT 
    sudo chown -R <cronuser> /var/spool/rrds 
    

Outcome

At this point, your host is configured for submission of monitoring data to GMOC. To submit data for one or more specific GENI aggregates, resources, or slice authorities, install another tango-monitor package for your specific aggregate, or your own custom software which uses gmoc.py.
