Something trying to connect to port 9090 but it's not listening


#1

Every minute I’m getting logfile entries about something from the software
trying to connect to localhost port 9090 but that port is not listening
on the server.

May 24 17:29:29 metasdemo metasfresh-webui-api.jar[528]: 2017-05-24 17:29:29.235 WARN 641 [ ][ ] — [gistrationTask1] d.c.b.a.c.r.ApplicationRegistrator : Failed to register application as Application [name=metasfresh-webui-api, managementUrl=http://metasfresh.some.domain:8181, healthUrl=http://metasfresh.some.domain:8181/health, serviceUrl=http://metasfresh.some.domain:8181] at spring-boot-admin ([http://localhost:9090/api/applications]): I/O error on POST request for “http://localhost:9090/api/applications”: Connection refused (Connection refused); nested exception is java.net.ConnectException: Connection refused (Connection refused)

Hi,
9090 is the port where our so-called metasfresh-admin would run if it was started. The different metasfresh services try to connect to it once a minute. If it’s not running, nothing bad happens besides that log message.
If your update to 5.10 went well after the workaround, you should be able to start metasfresh-admin via

systemctl start metasfresh-admin.service

the different metasfresh services should then report in and you can check out some of their internals by pointing your browser to port 9090.

PS: I’m not at my desk so the systemctl .. might have typos again.

Regards
Tobias

That worked. To get it to start with reboots had to run

systemctl enable metasfresh-admin.service
