Instructions

• Log into your Gitlab instance
• Navigate to your user settings page by clicking your name/avatar in the top right and then clicking Preferences
• In the left pane click on Access Tokens
• Create a new Personal Access Token
  • Give it a descriptive name like “Update Checker”
  • Under Select scopes check the read_api checkbox
  • Click the Create personal access token button to create the token
  • Copy the token value from the returned page
• Download the gitlab_update_check.sh script from this repository and place it in /usr/lib/zabbix/externalscripts/
• Run chmod +x /usr/lib/zabbix/externalscripts/gitlab_update_check.sh to make the script executable
• Test executing the script from the CLI of your Zabbix server by running the bash script inputting the gitlab hostname and your access token like ./gitlab_update_check.sh gitlab.example.com "PeRSoNaLaCcEsStOkEn"
  • Make sure the output is either “up-to-date”, “new version out”, or “update asap”
• Once the script works OK, download the zabbix_template_gitlab_update_check.xml Zabbix template from this repository and import it into your Zabbix server
• In Zabbix, navigate to the host you want to perform checks on
• Create a new macro on the host called {$GITLAB_TOKEN}, in the value field put the personal access token you generated on the Gitlab server
• Make sure the URL hostname of the host is in the “Host name” field setting for the host (ie: gitlab.example.com) if your server is accessed via https://zabbix.example.com/
• Apply the imported template (called “Template Gitlab Update Check”) to the host
• Find the new item on the host called “Update Status” and execute it to test it
• Check the latest data to make sure you are getting the proper value from the script
