Features

• Stream collection: Syslog,AVRO and JSON streams were supported in Be-release

• Persistence: Flume based persistence layer. Hbase is used for persistence

• Search and analyze:

  • Support for SQL query.

  • Time range for search can be specified. Histogram for search results.

• Custom Dashboard :

  • Build pre-defined views on data by adding widgets. Domain expert can define search query and save results on dashboard.

  • Search result type : Counts, Search result histogram charts.

• Real-time event generation (Intercepted logs and Alarms) based on Rules :

  • Intercepted logs: Mechanism to route messages into categories in real time while they are processed like stream for audit logs( install bundle etc.) .

Architectural Issues

• N/A

Security Considerations

• Currently syslog messages from device to collector are not encrypted. Also, connection from flume client to flume server is not secured. We will support data encryption in Centinel by Beryllium SR1.

  • Patch supporting TLS between external log host and collecter is merged(https://git.opendaylight.org/gerrit/#/c/35967/)

    • Operator can dynamicaly configure via UI/REST syslog collector type as Secure or Unsecure(for better performance)

    • Provides two way authentication between device and collector

    • Certificate and keys are saved in java keystore(jks)

Quality Assurance (test coverage, etc)

• Unit testing is done for all features. Unit test coverage is 65%.

• Unit testing: Used JaCoCo for code coverage visibility

• Manual system tests performed with success.

• No blocking issues identified as yet.

End-of-life (API/Features EOLed in Release)
