2024-06-19	MLA-4727	Investigate the root cause of Experiments page showing blank with "Loading failed" Workaround: The workaround to this issue is narrowed down to deleting all .pyc files under $SPLUNK_HOME/etc/ using the following command: find $SPLUNK_HOME/etc/ -name "*.pyc" -type f -delete
2024-04-30	MLA-4719	Getting AuthenticationFailed, Client is not authenticated while running MLTK model
2024-03-15	MLA-4716	DensityFunction: when using lower/upper_thresholds, BoundaryRanges incorrectly overlap so all values are being deemed outliers
2024-02-01	MLA-4710	Upgrade openssl library in PSC from version 1.1.1v to version 1.1.1x
2022-08-24	MLA-4320	Experiments' Search bar does not work with map command when used with $$ such as date_hour=$hour$ Workaround: Run your SPL in the regular Search bar. If you want to see SODA outlier visualizations, add show_density=true show_options="feature_variables,split_by,params" to your SPL and select Distribution Plot from the Visualization tab.
2022-07-20	MLA-4303	Singular Matrix error in StateSpaceForecast Algo
2022-07-03	MLA-4298, MLA-4160	'apply' search processor too aggressive in throwing exceptions
2022-01-10	MLA-4234	Deleting an alert after creating it does not work Workaround: Go to the list of alerts and delete your alert from there.
2021-11-25	MLA-4178	Experiment Alert search not created correctly from Assistant Workaround: Manually adjust the created search in savedsearches.conf or through the UI. Use the SPL created by the assistants a start.
2021-07-09	MLA-4026	What-If Analysis does not properly display on some Unix platforms
2020-08-03	MLA-3950	Apply command does not run if used from a sub search Workaround: Use appendcols command to append the column that will be returned from the subsearch to the savedsearch's columns, instead of assigning its value to a non-existing column in the savedsearch. Example: | inputlookup track_day.csv | fit LogisticRegression fit_intercept=true "vehicleType" from "batteryVoltage" "engineCoolantTemperature" "engineSpeed" "lateralGForce" "longitudeGForce" "speed" "verticalGForce" into "example_vehicle_type" makeresults count=50000 save as MLA3950 |savedsearch MLA3950 | appendcols \[| inputlookup track_day.csv | apply "example_vehicle_type" | table vehicleType] This will append the vehicleType column from the subsearch to the savedsearch columns.
2019-12-17	MLA-3701	Search bars in Assistants will not display more than approximately 500k rows Workaround: This is mostly a visual issue - the actual number of results the Assistant will use when fitting a model is not affected.
2019-12-11	MLA-3686	MLTK Assistants do not support quote characters in field names Workaround: Use the "rename" or "eval" command to rename the field prior to using it.
2019-10-09	MLA-3559	Loading settings from experiment history while in the Learn stage will lead to warnings, even when inputs are correct
2019-08-30	MLA-3423	Add a warning message when kfold_cv is set to number greater than half of the datasize
2019-07-12	MLA-3237	Anova table does not allow some special characters in formula so in field names also Workaround: Rename your field names before running "score anova" if they include one or more of those special characters:  (r'[&%$#@!`\|";<>^]')
