Ground Based Observatories (GBO) Site Monitoring Requirements William Rachelson THEMIS/GBO Review Mar 29, 2006
Site Monitoring Requirements • Document 149 A 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 THEMIS/GBO Review 2 Mar 29, 2006
“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. THEMIS/GBO Review 3 Mar 29, 2006
Magnetometer Packet Headers (automatically categorized) 1 -day Plots (stack plot visual: gaps, flat lines) 1 -month Plots (stack plot visual: slow drifts, sudden offsets) THEMIS/GBO Review 4 Mar 29, 2006
Magnetometer plots for visual inspection THEMIS/GBO Review 5 Mar 29, 2006
Imager Age/Statistics (automatically categorized) Low-res images (visual montage: black, snow, jaggy cutoffs) Low-res keograms (stack plot visual: gaps, horizontal lines) THEMIS/GBO Review 6 Mar 29, 2006
Imager Low-res Images for visual inspection THEMIS/GBO Review 7 Mar 29, 2006
Imager Low-res keograms for visual inspection THEMIS/GBO Review 8 Mar 29, 2006
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 THEMIS/GBO Review 9 Mar 29, 2006
Ground Based Observatories (GBO) Computer Configuration Control THEMIS/GBO Review Mar 29, 2006
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? THEMIS/GBO Review 11 Mar 29, 2006
Assembly Process Base Linux Installation is cloned from master HD image THEMIS/GBO Review 12 Mar 29, 2006
Assembly Process GBO-specific software pulled from Subversion repository GBO Software under Subversion Control: • Imager • Magnetometer • Cr 10 x communication • Web interface • Labview • Firewall THEMIS/GBO Review 13 Mar 29, 2006
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 THEMIS/GBO Review 14 Mar 29, 2006
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 THEMIS/GBO Review 15 Mar 29, 2006
Subversion is a software version control tool similar to CVS. THEMIS/GBO Review 16 Mar 29, 2006
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. THEMIS/GBO Review 17 Mar 29, 2006
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.
