The OnDemand realm does not show in the XDMoD portal

Make sure you are logged in with a user account that has either Center Director or Center Staff role. Note the admin user account that is created with xdmod-setup does not have these roles by default.

The xdmod-ondemand-ingestor command ran without error, but no data

Re-run the xdmod-ondemand-ingestor command with the --debug flag to show detailed information about what it is running. Things to double check:

• The webserver_format_str setting matches the data format in the log files
• The filenames of the log files end in .log or .log.N where N is a number
• The url specified on the command line exactly matches the url in the webserver log files. This should include the protocol part (https://) and any port numbers but not the trailing forward slash character.

The xdmod-ondemand-ingestor command fails with out of memory error

If the memory usage of the xdmod-ondemand-ingestor command reaches the php memory limit then it will exit with an error message similar to the one shown below

PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 86 bytes) in /usr/share/xdmod/vendor/kassner/log-parser/src/Kassner/LogParser/LogParser.php on line 113
2021-08-10 18:52:16 [critical] Allowed memory size of 134217728 bytes exhausted (tried to allocate 86 bytes) (file: /usr/share/xdmod/vendor/kassner/log-parser/src/Kassner/LogParser/LogParser.php, line: 113, type: 1)

This memory error is caused because the xdmod-ondemand-ingestor command loads all records in a log file into memory before loading into the database. This error can be mitigated by either splitting the log file into multiple smaller files (described in the Hints) or by increasing the php memory limit setting.
