CMS Space Monitoring Visualization

This page is intended for keeping track of development work on CMS Space Monitoring visualization based on CERN IT Monitoring Services unified infrastructure. It may be of interest to other CMS monitoring visualization projects.



Vidyo meetings are called as necessary, usually on Fridays at 16:00 CERN time.

30 September 2016 4pm CERN /9am Fermilab

Follow-up: CERN IT Monitoring and CMS ELK Use Cases

Agenda and connection details: Attended:

  • From CERN: Alberto. Borja, Pedro

Borja has shown SpaceMon data in Kibana (please follow a link from the indico page above) .
We discussed further steps, see Summary of tasks.

Summary of Tasks

As discussed at Sept, 30th meeting

- Could be done now (next couple of weeks)
1. move from monitqa to monit, so that it is accessible to anyone authenticated (MONIT)
2. send the doc on how to do dashboards and the basics of  kibana (MONIT)

3.  use one call to get all the SPACEMON data instead of multiple site by site calls like now (MONIT and SPACEMON)
4.  use the time gap of 1h interval to get what has changed in that gap, instead of receiving the whole data every time (MONIT and SPACEMON)

- Mid-term period (few more weeks)
5. get new aggregated data (e.g. weekly) provided with scripts and data comes via the http feeds. instead of internal processing with Spark (SPACEMON and MONIT)

- Longer Period (couple of months)
6. Define a MONIT workflow that can be extended  and adapted to flume data sources and processing by external projects (like SPACEMON). Without us doing the flume development. (MONIT)
7.  Move SPACEMON to this model were data sources, processing and visualization can be done and changed without MONIT intervention (MONIT and SPACEMON)
8.  enrich with the pledges from REBUS data already in MONIT (site names do not match probably) (SPACEMON helped by MONIT)

Elastic-Kibana-Grafana testbed at Fermilab

  • fermicloud318
  • OS: SLF 7.2
  • Setup by Kevin
  • Fermi-wide access with KCA based authentication
  • Used by Alessandro for his evaluation project, download [presentation] , [report].

Natalia's Elastic-Kibana instance at Fermilab

Server has been decommissioned during Sept 17th power outage, all steps are documented in Fermilab redmine (#12066, #13443, #13481)
  • cmsdev33
  • OS: SLF 6.8
  • Set up by Natalia
  • Behind FNAL and CMS firewalls. Only local access.
  • Used by Natalia for testing and reproducing visualizations developed by Alessandro

Prototype on monitqa server at CERN

  • Restricted access, open to a few developers on request
  • Look for monit_qa_spacemon_raw_metric_* data source in .
  • Initial configuration for the kafka agent:
        type: exec
        channels: ckafka cerror
        shell: /bin/sh -c
        command: curl -k -o - "" | python /etc/flume-ng/agent-httpsource/
        restart: true
        restartThrottle: 86400000
        logStdErr: true
