Hello,

You may also want to make sure the EPICS-related environment variable (EPICS_CA_AUTO_ADDR_LIST and EPICS_CA_ADDR_LIST) loaded by Archiver Appliance is correct, probably in your case "localhost" should be in the EPICS_CA_ADDR_LIST address list.

For example, in the Archiver Appliance single machine installation sample, the following line locates in sampleStartup.sh file, and setEPICSEnv.sh file sets the two environment variables above. In your case this line can be in the conf file,

source /opt/local/setEPICSEnv.sh

Regards,

Lin

Subject: Archiver Appliance PVs never connect to be archived, always "Initial Sampling"

Hello All,

I have started to build the epics archiver appliance following Hans repo at https://github.com/jeonghanlee/epicsarchiverap-env.  Everything seems to be working great with the application and I am able to access the archiver web application just fine.  I start up a basic softIoc with a couple PVs and my pyDM widget is able to control and access them just fine but I cannot get them to be archived by the appliance.  I can also use caget/camonitor/caput without any issue to manipulate the softIoc.   I saw another post about checking the ports in the appliances.xml but that seems to be correct from what I can tell.  I tried to look through the logs in /opt/epicsarchiverap/engine mgmt etl retrieval but I didnt see any errors that stood out.  I am not sure if its a connection issue with the ca and the archiver or a record thing I am missing but any advice would be helpful.  I have tried using ca://calc:a , calc:a but no luck getting it to archive.
