Bug fixes:

Breaking Changes:

• The agent now keeps track that it has pushed it's local configuration to the central collector by writing out a file named "config.synced" in the same directory where the config.json file is stored.

  When the "config.synced" file is present, the agent will overwrite its local configuration with the agent configuration it retrieves from the central collector on JVM startup.

  When this file is not present, the agent will push its local configuration to the central collector on JVM startup (overwriting any existing remote configuration), after which the agent will (re-)create the "config.synced" file.

• Export/import agent configurations (#426)
• Kafka plugin (#443)

Bug fixes:

• Unformatted sql on slow trace export (v0.11) (#460)

Breaking Changes:

• If you want to run multiple agents on a single box, you need to create a file named glowroot.properties in the agent directory (the same directory that contains the glowroot.jar file), and add this to the file:

  multi.dir=true
  

  The instructions have been updated at Agent Installation (with Embedded Collector) and Agent Installation (for Central Collector).
