Group,

 

I went down the rabbit hole[1] from Kay’s last email and got interested in Phoebus Olog.  After a bunch of reading, compiling, and deleting various things, I wound up getting things going using the Docker Compose instructions at: https://github.com/Olog/phoebus-olog/blob/master/README.md#running-using-docker-compose I can now access http://localhost:8080/Olog and get a json dump that looks relatively sane.

 

{ "name" : "Olog Service", "version" : "1.0.0", "elastic" : { "status" : "Connected", "clusterName" : "elasticsearch", "clusterUuid" : "Ji0ntEK9THKFARye4DsNlw", "version" : "6.8.13" }, "mongo-gridfs" : { "status" : "Connected", "mongo" : "{type=STANDALONE, servers=[{address=mongo:27017, type=STANDALONE, roundTripTime=3.9 ms, state=CONNECTED}]" } }

 

I think I should be able to point Phoebus to this Olog instance, and then get a table of log entries in Phoebus as shown on page 15 of Kunal’s presentation[2].  When I try using the menu Applications -> Utility -> Log Entry Table I get nothing on screen, and the error log [3] shows errors that suggest I don’t have something configured properly. 

    java.lang.NullPointerException: Cannot invoke "org.phoebus.logbook.LogFactory.getLogClient()" because "this.logFactory" is null

 

I tried adding org.phoebus.olog.es.api/olog_url=http://localhost:8080/Olog to settings.ini and relaunching, but apparently that’s not the magic incantation.  Can anybody point me to the docs that I’ve missed?
