Look into intercepting javascript packets from pump controller webserver

June 11, 2021

Decided at June 11 meeting that custom, serial-based pump control software unnecessary and we’ll use the turbo.control webserver interface for control of pump if needed for maintenance. We will try to decode javascript packets to pull telemetry values from them.

Observing modes spreadsheet

WD

Log file on kpf-asl-prime

June 1, 2021

• I could not persuade selinux (Security-Enhanced Linux) to allow rsyslog to write to our standard log locations $KROOT/var/log/.  I will have to ask Steve Allen to assist with sorting that out.

• Temporarily, I have left the computer in “Permissive” mode [ie, selinux is not enforcing its strict security rules] so that rsyslog can write to the Kroot directory.

WD

webKTL installation

June 10, 2021

Will allow us to monitor and control our devices

WD

Agitator run instructions (superceded by webKTL interface?)

June 10, 2021

After I finish the reconfig, the command line use will be:

To Start: put it into jog mode, and set speed:

modify -s kpfmot agitmod=jog   agitspd=1000   (or whatever)

<do something to home, gotta think about this, because we don’t actually care about a home>

To Stop:

modify -s kpfmot agitmod=halt

What’s missing from the above: we don’t have a definition of 'homing', but the software requires being homed.  Let’s discuss tomorrow.

Caution: initially, don’t command motion w/o being present, to confirm that it’s moving smoothly and not vibrating.

Talk to BJ Fulton about best way to export KPF telemetry data

BJ setting up grafana interface for viewing telemetry stream

• June 11: talk to Steve Allen about this, and also Keck

All

kpf-asl-prime package installation

June 10, 2021

• Steve did a bare-bones CentOS 8.3 install (adding GNOME and cmd line/GUI RAID software). Goal was to do minimum to get it running and on network.

• Different than kpf-server which was built up at UCSC

• June 11: Agreed to just add packages as needed ( and track them).

Currently not in use with cryostat, but will be in a couple/few weeks.

Discussed at June 10 meeting

SG

Tell Brad webcam usr/pwd

June 10, 2021

Now on SSL network, should be accessible from kpf-asl-prime

WD

KFP history (telemetry) on kpf-asl-prime

June 1, 2021

• The kpf history (telemetry) service is installed and running.  But it needs additional services added to its configuration; currently it’s monitoring just kpfpower and kpfmot.

WD

kpfmot consolidation

June 1, 2021

• The kpfmot service now incorporates all motion-control components: currently it contains the agitator controls, the source shutter controls, and the thorlabs filterwheel control.

WD

set up kpf-asl-prime as our main server

June 1, 2021

• kpf-asl-prime is more-or-less ready to do all its functions as instrument server.

• The daemons that Brad created for kpf-server, are now installed on kpf-asl-prime.

• Both of the KPF servers know where these services run — that is, you should be able to do a “gshow -s servicename …” and be able to monitor keywords from anywhere.

• The KPF master start/stop script knows about the history service, the Galil’s, and the filterwheel
