  1. Ground Based Observatories (GBO)Site Monitoring RequirementsWilliam Rachelson

  2. Site Monitoring Requirements • Document 149A describes the daily monitoring procedure for all GBO stations. • Procedure verifies science collection and system parameters—the overall health of all stations. • Appendix contains corrective procedures for detectable out of bounds conditions. • Three main categories: • “Monitor” • Magnetometer • Imager

  3. “Monitor” • Computer(disk, CPU, users, memory, software versions) • Temperatures(inside imager, hut, computer, mag) • Power system(voltages, UPS) • Network(bandwidth, latency) • Quantitative—RT website can automatically categorize values as acceptable or out of range.

  4. Magnetometer • Packet Headers(automatically categorized) • 1-day Plots(stack plot visual: gaps, flat lines) • 1-month Plots(stack plot visual: slow drifts, sudden offsets)

  5. Magnetometer • Magnetometer plots for visual inspection

  6. Imager • Age/Statistics(automatically categorized) • Low-res images(visual montage: black, snow, jaggy cutoffs) • Low-res keograms(stack plot visual: gaps, horizontal lines)

  7. Imager • Low-res Images for visual inspection

  8. Imager • Low-res keograms for visual inspection

  9. Summary • The daily monitoring procedure ensures ongoing operation of GBO stations. • Current Status: • RT website exists • Monitoring procedure documented • No dedicated personnel trained to perform this task yet

  10. Ground Based Observatories (GBO)Computer Configuration Control

  11. Overview • GBO station software looks like: • Base Linux Installation Vanilla Redhat 9 • GBO-specific packages Under Subversion Control • Site-specific configuration IP, Hostname, Magnetometer calibration • How are they assembled?

  12. Assembly Process • Base Linux Installation is cloned from master HD image

  13. Assembly Process • GBO-specific software pulled from Subversion repository • GBO Software under Subversion Control: • Imager • Magnetometer • Cr10x communication • Web interface • Labview • Firewall

  14. Assembly Process • Site-specific settings are applied to the software using “site-select” utility. Sets IP to: 131.232.13.26 Sets IP to: 128.32.147.213 Sets IP to: 24.237.236.231 Sets IP to: 69.156.232.74

  15. Monitoring and Upgrading • All software package version numbers are reported to the RT website for monitoring • Daily monitoring procedure includes checking versions • RT website has “good versions” specified • Updating software on each station is done as needed using a Subversion and Makefile process

  16. Subversion • Subversion is a software version control tool similar to CVS.

  17. GBO Wiki • The GBO Wiki captures incidents and site configuration information. • Pending Items • Site Quirks • Visit/Log entries and reports • Also documents common GBO tasks such as initializing hard drive, DNS maintenance, etc.

  18. Summary • A procedure exists for: • Reproducing fully configured GBO stations • Tracking deployed software versions • Updating software on deployed stations • GBO-specific software is maintained in the subversion repository. • The wiki captures GBO related knowledge.
