1. Ground Based Observatories (GBO) Site Monitoring Requirements William 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. GBO-specific software pulled from Subversion repository
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:

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. A procedure exists for:
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.
