GlitchTip is an Open Source error tracking system and you can self-host GlitchTip or subscribe to GlitchTip.com

It also does:

• Uptime Monitoring
• Application Performance Monitoring: https://gitlab.com/tikiwiki/tiki/-/merge_requests/9143, (which is similar to Real User Measurement).

• Add a new project in your GlitchTip instance by clicking the "Create New Project"
• Choose PHP as your platform, input the project name (yourtiki.org) and select your team

• Tiki23+ bundles sentry/sdk so you should not run Composer

• Note and copy your DSN from the left panel

1.1.3.1. Admin panel

• Use tiki-admin.php Setup Error Tracking feature in Admin > General > Error Tracking or

1.1.3.2. System Configuration)

Details System Configuration

Create a new folder named tikiconfig outside the web accessible directory, and inside this folder create a new prefs.ini file containing

[glitchtip]
preference.error_tracking_enabled_php = y
preference.error_tracking_enabled_js = y
preference.error_tracking_dsn = https://4bd1dec539c9496b9d3f3ef5bd284f70@glitchtip.example.com/4

Of course, replace the preference.error_tracking_dsn link with the DSN generated by GlitchTip

Now add the following lines to your existing local.php file in the /db folder

if (is_readable('../tikiconfig/prefs.ini')) {
    $system_configuration_file = '../tikiconfig/prefs.ini';
} else {
    trigger_error('Ini file not found: ../tikiconfig/prefs.ini', E_USER_WARNING);
}
$system_configuration_identifier = 'glitchtip';

Check the errors reported in your GlitchTip instance, by navigating to your project.

Sampling allows you to better manage the number of reported events, so you can tailor the volume of data needed. Use a value between 0 and 1. E.g.: 0.25 (will report 25% of the events)
Preference name: error_tracking_sample_rate
