7 In order to find the origin of an error, we suggest to use the logs resulting from tracing, which needs to be activated.
10 """"""""""""""""""""""
11 The DFC supports a REST API which includes features to facilitate troubleshooting.
13 One REST primitive, **status**, returns statistics and status information for the DFC processing.
14 Here follows an example on how to use (here curl is used, but a web-browser can also be used. If you are
15 logged in to a container, wget can probably be used):
17 ``curl http://127.0.0.1:8100/status -i -X GET``
19 The following features are implemented by enabling so called 'actuators' in the Springboot framework used:
21 **loggers** - is used to control the logging level on different loggers (so you can enabled debug tracing on a certain
24 **logfile** - get logged information.
26 **health** - get health check info, there is currently no info here. But the endpoint is enabled.
28 **metrics** - read metrics from the Java execution environment; such as memory consumption, number of threads, open file
31 Here follow some examples:
32 Activate debug tracing on all classes in the DFC:
34 ``curl http://127.0.0.1:8100/actuator/loggers/org.onap.dcaegen2.collectors.datafile -i -X POST -H 'Content-Type:
35 application/json' -d '{"configuredLevel":"debug"}'``
39 ``curl http://127.0.0.1:8100/actuator/logfile -i -X GET``
41 Get build information:
43 ``curl http://127.0.0.1:8100/actuator/info``
45 Get metric from the JVM. This lists the metrics that are available:
47 ``curl http://127.0.0.1:8100/actuator/metrics -i -X GET``
49 To see the value of a particular metric, just add \/[nameOfTheMetric] in the end of address, for example:
51 ``curl http://127.0.0.1:8100/actuator/metrics/process.cpu.usage -i -X GET``
57 If there is an error linked to the certificate, it is possible to get information about it. A possible cause for the
58 error can be that the expiry date of the certificate is past.
60 ``keytool -list -v -keystore dfc.jks``
62 The command to encode the b64 jks file to local execution is (the \*.jks.b64 is in the repo and the Dockerfile is
63 encoding it into .jks. So when you pull from nexus, this won't be needed, only when git-checkout and java/mvn run):
65 ``base64 -d dfc.jks.b64 > dfc.jks``
68 Common logs due to configuration errors
