Versions for ownCloud 9.0 and 9.1 are limited and only work in debug mode and without user interface. For more features, please update your server version to 10.0
Enabling this ownCloud diagnostic module will result in collecting data about all queries and events in the system per request.
It will collect information about any type of the request to the server, summarize it and store in the form of log or in any other requested form (export to monitoring).
Module allows to diagnose only selected users after their authentication or enabling collecting data globally for all users with "debug mode".
You can collect data from selected users not affecting performance of the system of other users (data wont be collected and logged).
By default, none of users is selected - to start logging please select user or allow collecting all data
Log can be found in the folder data/diagnostic.log
To install, go to /apps in your ownCloud installation directory and git clone https://github.com/owncloud/diagnostics. In the apps admin panel enable Diagnostics app.
- To enable app using command line:
sudo -u www-data php occ app:enable diagnostics
- To enable log levels, e.g. "SUMMARY":
sudo -u www-data php occ config:app:set --value 1 diagnostics diagnosticLogLevel
- To enable logging after authentication of specific users using command line:
sudo -u www-data php occ config:app:set --value "[\"test_shareMountInit\", \"admin\"]" diagnostics diagnosedUsers
- To enable debug mode globally:
sudo -u www-data php occ config:system:set --value true debug
Each SUMMARY log if referencing EVENT and QUERY logs via reqId.
This allows to build full timeline of the events and corresponding queries for specific type of request e.g. "PROPFIND", only for selected users, as requests are coming.
