1.6.0 release note

You must create 2 new HBase tables if you are upgrading from a previous release.

AgentStatV2
TraceV2

For more information on what these tables do, please refer to the Trace/AgentStat improvements section below.

ASM

We have changed our default bytecode instrumentation engine from Javassist to ASM and you will now experience faster application startup time especially in an environment with a lot of Spring beans.
This change also allows us to add powerful new APIs for you to utilize when developing plugins in the future.

We have added the following option to pinpoint.config to configure bytecode instrumentation engine used by the agent.

pinpoint.config

profiler.instrument.engine=ASM

Possible values are:

• ASM (default) - uses ASM for bytecode instrumentation
• JAVASSIST - uses Javassist for bytecode instrumentation

Please note that JAVASSIST instrumentation is deprecated and will be removed in future release.

Trace/AgentStat improvements

Huge improvements have been made to storing trace and agent stat data. We've experienced upwards of 60-70% improvement in I/O performance and storage capacity internally.
We highly recommend you create the following tables when upgrading from 1.5.x.

AgentStatV2
TraceV2

We have added the following options to pinpoint-collector.properties and pinpoint-web.properties to configure which tables to use.
Default values have been set to ensure backwards compatibility so you most likely will not need to change anything after creating the tables above.

pinpoint-collector.properties

collector.span.format.compatibility.version=v2
collector.stat.format.compatibility.version=v2

Possible values are:

• v1 - writes data to AgentStat/Trace table.
• v2 (default) - writes data to AgentStatV2/TraceV2 table.
• dualWrite - writes data to AgentStat/Trace and AgentStatV2/TraceV2 tables.

pinpoint-web.properties

web.span.format.compatibility.version=compatibilityMode 
web.stat.format.compatibility.version=compatibilityMode 

Possible values are:

• v1 - reads data from AgentStat/Trace table.
• v2 - reads data from AgentStatV2/TraceV2 table.
• compatibilityMode (default) - reads data from AgentStatV2/TraceV2 and if nothing is found, reads data from AgentStat/Trace tables.

Known Issues

• When profiling Jboss, you must set profiler.instrument.engine=JAVASSIST in pinpoint.config
