PHP Tracer releases

Instana monitors your PHP environment by using the PHP sensor and tracer. The PHP sensor provides infrastructure metrics, while the PHP Tracer provides automated code instrumentation and tracing data across your environment. For more information, see Monitoring PHP. To get specific tracer updates, you need to install the associated agent version specified in the release version.

Features

PHP Tracer now supports the following elements:

  • The Monolog 3 library. For more information, see Monolog.
  • The INSTANA_STACK_TRACE_LENGTH environment variable. For more information, see Environment variables.

Improvements

The time that is taken to start the PHP Tracer is significantly reduced by moving the handshake process with the Instana agent to a background thread.

Fixes

  • Previously, when PHP Tracer lost connection to the Instana agent (for example, due to a restart during its daily update cycle), traces were lost, and you had to reload the PHP runtime to reestablish the connection. Now a detection mechanism for this connection loss is established. This mechanism triggers the handshake process with the Instana agent in parallel on a background thread to reestablish the connection.
  • Previously, the instana.backtrace_limit setting was capped at 35 entries. Now the default or capped value is 25 entries. For more information, see PHP Tracing extension.
