XINA Struct Trend

The XINA Struct Trend command line utility generates trend data products for a specified time range or Event Intervals. It is used by the XINA Trend Task. Generated data products include:

  • Binned trend data
  • Configurable trend plots
  • Log file

Arguments

Name Req Description Default
cache Cache directory path. Used for any persistent caching across tasks for optimization purposes.
conf ✓ File path to the JSON config containing the trend parameters.
env ✓ File path to the JSON environment file which defines environment parameters such as project specific paths.
help Print available options.
host XINA Tunnel host. "localhost"
port XINA Tunnel port. 41746
import ✓ Import directory path. Files that need to be imported will be placed here. struct_trend is responsbile for generating the corresponding import action file but xina-run will perform the actual importing.
log ✓ File path that log events will be written to.
out ✓ Ouptut directory path. Files placed here will be uploaded and accessible directly from the Task interface (e.g. notifications panel).
post ✓ Post directory path (for post-import outputs) e.g. uploading log files to the Task record.
task ✓ File path to the JSON file containing info about the Task.
temp ✓ Temp directory path for storing temporary files during execution.

conf

The below table describes the available fields in the conf JSON file and is used to control how data should be trended.

Name Type Req Description Default
model utf8text ✓ Path of model to trend data from e.g. moma.fm
copy boolean If true, the zip file will be uploaded and available from the Task interface. false
trend utf8text The name of the Trend Definition to generate the trend from.for. If provided, then the profiles, trend_conf, and plot_conf will be loaded from it.
label utf8text The text that will be used to name the files and final zip file. The format will be like 2024_06_12_00_00_00_2024_06_12_00_20_00_profile_label
profiles set(utf8string) Name of profile(s) to include in trend
trend_conf struct_trend_conf See struct_trend_conf
plot_conf jsonobject See trend plot conf

Example conf:

This example performs a trend export with fields provided directly in the conf object.

{
  "label": "Test_Trend_From_Conf",
  "desc": "This is a test trend. The Trend parameters are provided in the conf.",
  "model": "model.path",
  "copy": true,
  "profiles": [
      "TEST_PROFILE"
  ],
  "trend_conf": {
      "t": [
          {
              "start": "2024-11-01T00:00:00Z",
              "end": "2024-11-01T00:10:00Z"
          }
      ],
      "bin_minutes": 1,
      "disable_filter": false,
      "intervals": null
  },
  "plot_conf": {}
}

In this example, the trend will be generated from an existing Trend Definition named TEST_TREND.

{
  "trend": "TEST_TREND",
  "model": "model.path",
  "copy": true
}
