archive appliance some PVs no data

[Rong Huang via Tech-talk <tech-talk at aps.anl.gov>]

Hello,

I installed Archiver Appliance last year while APS was down. To learn how to use it, I started archiving some PVs, and paused them. I "resumed" the archiving now while APS is back, but some PVs can be archived, some PVs cannot.

I use http://strawberry.ls-cat.org:17665/mgmt/ui/index.html to Achive/Pause/Resume archiving.

I use http://strawberry.ls-cat.org:17668/retrieval/ui/viewer/archViewer.html to view/retrive data.

The problem, using "21:C1:MO:E:ActPos" as an example, the archViewer website showing one value straight line, "113" Kev, for any display time ranges. "113" comes from the mono E reading when I started archiver appliance last year but not the current E reading.

I deleted the PV "21:C1:MO:E:ActPos" and its data from archiver appliance, re-entered the PV and started its archiving, the mgmt page showed it "Being archived", "appliance0", "Connected? true", "Sampling period: 10.0".

archViewer web page shows a flat line of "0" for any time range.

There is no data file of this PV saved in /arch/sts/ArchiverStore/21. (Even there is no subdirectory of "C1" in /arch/sts/ArchiverStore/21 after I manually removed it and deleted all 21:C1:* PVs)

Restarting archiving appliance (sampleStart.sh stop & sampleStart.sh start) does not help.

But some PVs can be archived after "resume" (some of them might have noise, therefore the values were varying all the time in the past).

I am using apache-tomcat-9.0.86. mysql 8.0.37-0ubuntu0.22.04.3, I installed Archinver Appliance using single_mechine_install.sh.

Thanks a lot!
