    • Weather station - "ie_Open - device already" popup window indicating not all the data was being sent. Restarting the pc fixed this. Documented in wiki.
    • FacSum on middle display in rm507 was not showing new radar image. Fixed by reinstalling the lbto-tcsweb rpm.

  • AO-Cravat:
    • Completed draft POI and a separate design document (waiting for Al to comment on them).
    • Next to spend some time on plotly.js.
    • LBC non-sidereal guiding problems (IT#7847), found the cause, planning on a temporary fix (long term fix would be to rewrite the non-sidereal guiding for LBC, currently planned on letting users able to tweak some parameters to get around the problem if it occurs, but still need to change LBC code and release a new version).
    • Need to understand more on what needs to be added to the LBC fits keyword.
    • Working on post processing LBC telemetry data.
    • MODS power on had some glitches on Friday. Worked with Olga and finally all came back on successfully and we were able to take data as well. (It appears that the power outage on Friday tripped the MODS IEB/LLB breakers and they had to be reset. M2.BC initially also had some problems booting up, but become okay after the breakers reset. Also had to run fitsflush to get MODS images off to /newdata mount).


  • OC, WPC, Management
  • 20190927 power shutdown/restart
  • ARGOS BCU comms and followup with WG
  • DMS
    • alta iterations
    • m1 surf WIP

Last week:
  • CHAOS: Reviewed additional current alert clients, LUCI1monitor, watch4dew, lbccontrol loggers, Zabbix.
    • Stats server Zabbix log says it forwards some warnings and errors to ALH.
    • ARGOS uses a local Zabbix only for diagnostic graphs of laser-related activity. ALH integration is a to-do.
    • Reviewed current ALH config files for lists of monitored devices/activities.
    • LBC, per YZ, uses tcl/tk cron jobs on lbccontrol.
    • AO, per XZ, already uses ALH.
  • SupportScripts:
    • Reviewed JH's desires beyond mere Python 3 compatibility.
    • Example: would like dwell time between dir list updates below 1s. See if there's a way for DS9/XPA to support faster update rate.
    • Script really needs the 1s sleep between frames for DS9 to be ready, otherwise DS9 freezes or crashes in short order.

This week:
  • CHAOS: Finish non-ALH alert review and research alternative alert collection alternatives.
  • DMS: Discussed potential Monnit plot modifications with PG. Will review with MB.
  • SupportScripts: Review test results w/ JH and suggest modernization solutions.
