Overview

...
DAQ:NEH:tmo are the variables that Ric's prometheus exporter generates and are readable in tmo.pvlist. Added DAQ:NEH:rix to rix.pvlist. Restarted rix/tmo/drp/mcc-daq gateways.
Reliability
In May 2024 TMO was unable to successfully complete a scan: would fail around 30 steps. Bypassing the gateway dramatically improved the situation. Notified Zach of this issue.
Bypassing Gateways
Router work has been done to allow EPICS variables to be accessed using EPICS_CA_ADDR_LIST and EPICS_PVA_ADDR_LIST. Some details are here: ACR Realtime Feedback#RouterNetworkSupport
Change Requested by Tyler

Hi Matt, Hi Chris, during the next PAMM, I would like to add the following rule to the DRP gateway configuration and reboot the gateway to pick up the new rule:
DAQ:NEH:XPM:0.* ALLOW RWLAS
This would allow us to configure XPM0 from the laser subnet which would be much more convenient for our laser/timing operators. My intent is to have a script that programs our standard laser XPM0 configuration(s), and make this available to our laser operators via a button on a screen. This way if the laser operators see that the XPM configuration is gone (such as after a power outage) they can press this button and restore laser operation without the need to call me or Dring.
