[Fiware-lab-federation-nodes] New release 5.4.2 of FIWARE Monitoring

[FERNANDO LOPEZ AGUILAR]

Dear FIWARE Lab infrastructure owners,

We would like to inform that a new release 5.4.2 of FIWARE Monitoring is available, including new features and fixes for most of the known bugs. For this reason, we strongly suggest all regions to upgrade to this latest release:

https://github.com/SmartInfrastructures/ceilometer-plugin-fiware/releases/tag/v5.4.2

As you can see in the changelog, there are a number of new features and fixes with respect former releases 5.3.3 (June) and 5.4.1 (July). For your convenience here is a summary of files changed on the latest 2 releases:

       - From v5.4.1 to v5.4.2
              README.md
              compute_pollster/host.py
              region/region.py
              tools/ceilometer_ha_restart.sh
              tools/fiware-check-monitoring.sh
              tools/monasca_restart.sh

       - From v5.3.3 to v5.4.1
              README.md
              config/compute/etc/ceilometer/pipeline.yaml
              config/controller/etc/ceilometer/monasca_field_definitions.yaml
              config/controller/etc/ceilometer/pipeline.yaml
              region/OSVersionComponent.py
              region/region.py


Depending on your current release, the process to upgrade to 5.4.2 would require several steps. As a general rule:

1) Download files (as a tarball) from https://github.com/SmartInfrastructures/ceilometer-plugin-fiware/archive/v5.4.2.tar.gz and decompress into a temporal folder.

2) Copy the "fiware-check-monitoring.sh" script located at "tools/" into your preferred working directory (could be /root) at every Controller and run it with the "--verbose" flag. The script will analyze your environment, checking for:
       - Latest version of pollsters
       - Latest version of configuration files
       - Overall status of monitoring and monitored data

3) Based on the check script output, you should manually replace old files, if needed, or copy new ones, following the updated installation guide available here:

https://github.com/SmartInfrastructures/ceilometer-plugin-fiware/blob/v5.4.2/README.md

Locate your installation directory of Ceilometer package (usually, pip command shows such information):

# pip show ceilometer
---
Name: ceilometer
Version: 2015.1.1
Location: /usr/lib/python2.7/dist-packages

We refer to such location as $PYTHON_SITE_PKG. Giving that, for sure you'll have to update these files:

       At the Compute Nodes:
       - compute_pollster/host.py ==> <PYTHON_SITE_PKG>/ceilometer/compute/pollsters/host.py

       At the Controllers:
       - region/region.py ==> <PYTHON_SITE_PKG>/ceilometer/region/region.py

And also copy new files:

       At the Controllers:
       - region/OSVersionComponent.py ==> <PYTHON_SITE_PKG>/ceilometer/region/OSVersionComponent.py

Finally, some changes have been introduced in the configuration files, and the check script should detect whether current configuration files need to be updated. These files are involved:

       At the Compute Nodes:
       - /etc/ceilometer/pipeline.yaml

       At the Controllers:
       - /etc/ceilometer/pipeline.yaml
       - /etc/ceilometer/monasca_field_definitions.yaml

You will find samples for those files at "config/" folder of the downloaded files. PLEASE BE CAREFUL when merging the sample files with your current configuration files (take into account the URLs, the refresh intervals, etc.)

4) Restart Ceilometer and Monasca Agent to apply changes: see details in the documentation or use the new support scripts under "tools/".

5) Finally, run the check script once more to verify the installation/upgrade


Last but not least, all regions WHICH ARE STILL USING THE OLD MONITORING are strongly suggested to upgrade as soon as possible to the v5.4.2 release.

Please send an email to fiware-lab-help at lists.fiware.org<mailto:fiware-lab-help at lists.fiware.org> if you encounter any problem or if you need help, once that the problem is resolved, the FIWARE Ops team will close the ticket and proceed with the configuration of the Infographics GUI in order to receive data from your new monitoring system.

Finally, please remember that the new Karma calculation will include a penalization if the node hasn't installed the new monitoring architecture.

Best regards,
  FIWARE Ops team
