PHP Slim

Installation​

  1. Install the Datadog PHP tracer.

    curl -LO https://github.com/DataDog/dd-trace-php/releases/latest/download/datadog-setup.php
    php datadog-setup.php --php-bin=all
    rm datadog-setup.php

  2. Configure the tracer for CLI (the config file is generally available at /etc/php/<php_version>/cli/conf.d/98-ddtrace.ini).

    ddtrace.ini
    datadog.service = <app_name>
    # send traces to CubeAPM
    datadog.trace.agent_url = http://<ip_address_of_cubeapm_server>:3130
    # optional settings
    datadog.env = myenv
    datadog.version = 1.2.3
    datadog.tags = mykey1:myvalue1,mykey2:myvalue2

  3. Configure the tracer for FPM (the config file is generally available at /etc/php/<php_version>/fpm/conf.d/98-ddtrace.ini).

    ddtrace.ini
    datadog.service = <app_name>
    # send traces to CubeAPM
    datadog.trace.agent_url = http://<ip_address_of_cubeapm_server>:3130
    # optional settings
    datadog.env = myenv
    datadog.version = 1.2.3
    datadog.tags = mykey1:myvalue1,mykey2:myvalue2

Sample App​

A working example is available at https://github.com/cubeapm/sample_app_php_slim/tree/datadog.

Troubleshooting​

The following can be used for troubleshooting:

ddtrace.ini
# When enabled, sends debug logs to PHP's error_log instead of datadog.trace.log_file
datadog.trace.debug = On
# Send debug logs to a log file for CLI
datadog.trace.log_file = /var/log/php8.3-cli.log
# Send debug logs to a log file for FPM
datadog.trace.log_file = /var/log/php8.3-fpm.log

# Enable Datadog tracer debug logging if needed to see detailed log 
datadog.trace.log_level = debug
