Monitors various aspects of Nextcloud instances like state, quota and disk usage of all users, number of apps with available updates, database php opcache hit rate and so on. Gives additional information regarding versions of Nextcloud, database, PHP, web server etc. Caveats: Tested only with Nextcloud versions 25/26/27/28 Tested only with MySQL/MariaDB as database backend Please feel free to add other working environments via review. Upgrade from older MKPs (before 2.4.0): If you upgrade from a already installed version before 2.4.0, you have to re-create your rules for the "Nextcloud Server Information" (reason: massive parameter changes). Steps to accomplish this without problems: 1. Take a screenshot of your settings in the above mentioned ruleset 2. Assure that you have access to the passwords/tokens you used within the current rules 3. Delete all rules for "Nextcloud Server Information" 4. Install and enable the new MKP 5. Re-create your rules with the previously saved information from steps 1 and 2 6. Apply your changes Hint: You have to create an app password now for accessing your Nextcloud instance. For this to accomplish login to your Nextcloud server with an administrative user account. Go to "Personal Settings|Security" and take note of the section "Devices & Sessions". Create the app password via clicking the button "create new app password". You may use this password explicitly within the rule or store it first in the password safe of CheckMK. General installation instructions: 1. Upload and enable the MKP 2. Apply changes 3. Click Setup, search for "Nextcloud" 4. Click on "Nextcloud Server Information" below "Other integrations" 5. Create a new rule and fill in all mandatory information (Hostname, Username, App Password) 6. Adjust all other options to your needs 7. Bind this rule to your Nextcloud host object (e.g. via "Explicit hosts") 8. If you have no host object at all, create a dummy host for this (with no IP or something like 127.0.0.2) 9. Assure that your agents settings for this host object are correct (must contain "Configured API integrations") 10. Apply your changes 11. Execute a service discovery on your Nextcloud host(s) and accept the newly detected services 12. Feel free to adjust the various parameters for thresholds within the available parameter sections (Setup, "Service monitoring rules" after searching for "Nextcloud") Version history: 2024/01/13 2.5.2 Due to several user requests: Repackaged only to set the minimum required version CheckMK to 2.1.0p1 2024/01/12 2.5.1 Added versions for apps with available updates 2024/01/12 2.4.1 Removed Parameter "token", switched to parameter "app password" only 2024/01/12 2.4.0 Integrated Password Store for App Password, some changes for compatibility with NC 28 added 2023/11/26 2.3.4 Fixed agent crash if opcache_get_status is disabled by server settings, thanks to Marcus Klein for reporting (and solving!) this bug 2023/08/16: 2.3.3 Fixed some misleading information strings regarding database PHP opcache 2023/08/08: 2.3.2 Now compatible with CheckMK 2.2 2023/03/27: 2.3.1 Fixed several bugs in parameter handling 2023/03/23: 2.2.1 Adjusted parameter handling Added check for "free space on disk" (incl. adjustable levels) Added adjustable levels for "number of files" 2023/03/11: 2.2.0 Upload initial public release
