Step 1 – Check if Dynatrace Log Monitoring is enabled globally<\/h2>\n\n\n\n
  1. In the Dynatrace menu, go to Settings<\/strong> > Monitoring<\/strong> > Monitored technologies<\/strong>.<\/li>
  2. Find Log Monitoring<\/strong> in the list of supported technologies, and select Edit<\/strong> (pencil icon).<\/li>
  3. Check if Monitor Log Monitoring on every host<\/strong> option is enabled.<\/li>
  4. Turn on Monitor Log Monitoring on every host<\/strong>.<\/li><\/ol>\n\n\n\n

    Step 2 – Check if Dynatrace Log Monitoring is enabled on a host level:<\/h2>\n\n\n\n
    \n\n\n
    # To Check if Log Monitoring is enabled or not<\/span>\n$ cd \/opt\/dynatrace\/oneagent\/agent\/tools\n$ .\/oneagentctl --get-system-logs-access-enabled\n$ .\/oneagentctl --get-app-log-content-access\n\n# To Enable Log Monitoring is enabled or not<\/span>\n$ .\/oneagentctl --set-system-logs-access-enabled=true<\/span> --restart-service\n$ .\/oneagentctl --set-app-log-content-access=true<\/span> --restart-service\n<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
    \n\n\n\n
    Step 3 – Understanding OneAgent Changes<\/h2>\n\n\n\n
    Dynatrace Log Monitoring uses OneAgent log module enabled by default<\/strong> with all OneAgent installations.<\/p>\n\n\n\n
    While Log Monitoring does not require any specific configuration<\/strong>, you can modify some of the options available for OneAgent log module.<\/p>\n\n\n\n
    You can adjust:<\/p>\n\n\n\n
    • Enable and disable automatic log detection for different technologies.<\/li>
    • Define default timezone in containers.<\/li>
    • Enable defining the storgae configuration by a configuration file on the host.<\/li>
    • Define specific location where the timestamp and severity occur in your incoming log data.<\/li>
    • Define the maximum number of log group instances per entity.<\/li><\/ul>\n\n\n\n
      1. From the Dynatrace menu, select Settings<\/strong> > Log Monitoring<\/strong> > OneAgent settings<\/strong>.<\/li>
      2. Adjust settings and Save changes<\/strong>.<\/li><\/ol>\n\n\n\n
        \"\"<\/figure>\n\n\n\n
        Step 4 – Host-specific OneAgent settings for Log Monitoring<\/h2>\n\n\n\n
        1. In the\u00a0Dynatrace menu, go to\u00a0Hosts<\/strong>\u00a0and select your Linux host.<\/li>
        2. On the host overview page, select\u00a0More<\/strong>\u00a0(\u2026<\/strong>) >\u00a0Settings<\/strong>\u00a0in the upper-right corner of the page.<\/li>
        3. One the\u00a0Host settings<\/strong>\u00a0page, select\u00a0Log Monitoring<\/strong>\u00a0and\u00a0OneAgent settings<\/strong>.<\/li>
        4. Adjust settings and\u00a0Save changes<\/strong>.<\/li><\/ol>\n\n\n\n
          \"\"<\/figure>\n\n\n\n
          \"\"<\/figure>\n\n\n\n
          \"\"<\/figure>\n\n\n\n
          \"\"<\/figure>\n\n\n\n
          \"\"<\/figure>\n\n\n\n
          Step 5 – Enable using Configuration File [optional]<\/h2>\n\n\n\n
          The configuration file located on each OneAgent is used to set three options<\/strong>. For security reasons, these options can only be set on the host level and are available only by creating a JSON file in a specific location:<\/p>\n\n\n\n
          • Linux: \/var\/lib\/dynatrace\/oneagent\/agent\/config\/<\/code><\/li>
          • Windows: %PROGRAMDATA%\\dynatrace\\oneagent\\agent\\config\\<\/code><\/li><\/ul>\n\n\n\n
            The configuration file name must have the\u00a0json<\/code>\u00a0extension<\/strong>; the file name is otherwise unrestricted.<\/p>\n\n\n\n
            By default, these options are set for the OneAgent log module to operate properly and to auto-detect log files on the specific host. Modifying this configuration file is not required.<\/p>\n\n\n\n
            \n\n\n
            {\r\n  \u201cagent-configuration\u201d:[\r\n    {\r\n      \u201cAppLogRemoteConfiguration\u201d:true<\/span>,\r\n      \u201cAppLogContentAccess\u201d:true<\/span>,\r\n      \u201cAppLogAutoDetection\u201d:true<\/span>\r\n    }\r\n  ]\r\n}<\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\n
            \n\n\n\n
            Step 6 – Add Log sources and storage<\/h2>\n\n\n\n
            To include or exclude specific log sources from storage<\/p>\n\n\n\n
            1. Select\u00a0Settings<\/strong>\u00a0from the Dynatrace navigation menu and in the\u00a0Log Monitoring<\/strong>\u00a0section, select\u00a0Log sources and storage<\/strong>.<\/li>
            2. Select\u00a0Include all logs<\/strong>,\u00a0Include the following logs<\/strong>, or\u00a0Exclude the following logs<\/strong>\u00a0from the list.<\/li>
            3. Switch between tabs to select logs from\u00a0Hosts perspective<\/strong>\u00a0or from\u00a0Process groups perspective<\/strong>.<\/li>
            4. Select\u00a0Save changes<\/strong>.<\/li><\/ol>\n\n\n\n
              \"\"<\/figure>\n\n\n\n
