- Look on main hutch grafana page at upstream-link-status graph
- ssh mcclogin (Ken Brobeck should be contacted to get access, in particular may need access to softegr account).
- ssh softegr@lcls-srv01 (Matt chooses "user 0")
- look at fanouts that are upstream of xpm:0. three layers to get all the way back to the source (the TPG which runs the whole accelerator, has a clock input from master source. clock could conceivably go away). Moving upstream:
- caget TPF:LTU0:000:RXLNKUP (immediately upstream)
- caget TPF:IN20:000:RXLNKUP
- caget TPF:GUNB:000:RXLNKUP (fanout that TPG drives)
- caget TPG:SYS0:1:TS (prints out timestamp from TPG, which is a check to see that TPG is running)
- caget TPG:SYS0:1:COUNTBRT (should be 910000 always)
- an example of it working:
- to see history run "lclshome": exposes archiver on the right hand side (see picture in LCLS1 section above)
- see MCCEpicsArchiverAccess for a video on how to access the MCC epics archiver (currently the above values are not in the archiver, but Matt is going to ask Carolina to add them)
