Version 1.0.1

  • The Java agent collects dependency information about the following:
    • HTTP calls made via HttpClient, OkHttp and RestTemplate (Spring).

    • JDBC calls made with Oracle DB and Apache Derby DB clients.
    • Support the 'executeBatch' query type for prepared statements – The SDK will show the statement with the number of batches.

Note that this change may cause a significant restatement of user and session counts as only user-originated sessions are being counted now.

Version 0.9.4

  • Support collecting performance counters from 32-bit Windows machines.
  • Support manual tracking of dependencies using a new trackDependency method API.
  • Ability to tag a telemetry item as synthetic, by adding a SyntheticSource property to the reported item.
