AW: Indicating IOC Console Message Activity

["Sintschuk, Michael via Tech-talk" <tech-talk@aps.anl.gov>]

Hi Matt,

 

I know about procServ but not about procServControl. The PV $(P):IOCOUT sounds like just the thing what I’m looking for. Thanks for the hint!

Is this the most recent repo: GitHub - DiamondLightSource/procServControl: EPICS/CA control of running procServ instances ?

 

Cheers,

Michael

Hi,

 

Are you using procServControl? It does have a waveform record used to display the most recent IOC output ($(P):IOCOUT). So that record will process when there is new IOC output, and the timestamp could be displayed on a screen. Or, some database logic can be added that detects it and flashes an LED.

 

Cheers,

Matt

Dear all,

sometimes it happens that an IOC prints messages (errors, warnings, notes, etc.) to its console, and I don’t notice them immediately because I’m not always logged into that console (via procServ).

If there is a constant stream of such messages, I would like to be notified about that.

I’m wondering whether it’s possible to implement a PV in the IOC that indicates console message activity — not the message contents themselves, but simply that some console output occurred.

Basically, I’d like to have a flashing LED (in Phoebus) whenever the IOC is “firing” messages of any kind. That would be my signal to log into the console and check what’s going on.

Has anyone already implemented something like this or worked in a similar direction?

 

Best regards,

Michael
