Re: EPICS Alarm system via web browser

Hi:

The CSS 'beast' alarm system updates the configuration RDB with the current state of alarms.
This means you can write a web app that periodically displays the 'current' alarms by reading from the RDB.

This is actually done as part of our JSP-based alarm reporting package, see "Alarm Reports" on http://ics-web.sns.ornl.gov/css/products.html.
ITER is planning to create a new alarm reporting system, see https://github.com/ControlSystemStudio/cs-studio/issues/597.
Meanwhile, FRIB and BNL just reported at the EPICS meeting this week how they route all alarm system messages into MongoDB/ElasticSearch to also get web-based alarm reports, see talk by Kunal on the EPICS meeting web page.

ITER had also ported the CSS alarm table & tree to RAP, which means you can see the same alarm table on the web, but this is a low-performance option that wouldn't be suitable for a web site that everybody at your site opens up.

Thanks,
-Kay

Subject: EPICS Alarm system via web browser

Does anybody have a recommendation on an EPICS Alarm system that you can view via web browser somehow?

At STAR/BNL, we have been using ALH for a number of years.  One of the member of the collaboration would like to be able to see alarm systems via web browser. Ideally, what he can see remotely is the same as what the shift crew can see in the control room, but not necessary to be able to control remotely via web.

Other options for alarms are to write a soft IOC specifically for this, CSS BEAST, Nagios Alarm Handler, CA Watcher, and CSS Alarm System (DESY).  However, as far as I can tell, none of them appears to be able to publish the EPICS alarm info on the web, unless I'm missing something.  I guess Nagios Alarm Handler can work for this, but is there any other options out there?
