Timing Link Glitches
- 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)
- to see history run "lclshome": exposes archiver on the right hand side. cpo couldn't bring this up (xcb error?) but weaver could
