Hi

here is the default spl of App: Splunk App for Data Science and Deep Learning (Time Series Anomalies with STUMPY -Time Series Anomaly Detection with Matrix Profiles)

| inputlookup cyclical_business_process.csv
| eval _time=strptime(_time, "%Y-%m-%dT%H:%M:%S")
| timechart span=15m avg(logons) as logons
| fit MLTKContainer algo=stumpy m=96 logons from _time into app:stumpy_anomalies
| table _time logons matrix_profile
| eventstats p95(matrix_profile) as p95_matrix_profile
| eval anomaly=if(matrix_profile>p95_matrix_profile,1,0)
| fields - p95_matrix_profile

 

 

now want to run this command for my data, here is the sample log:

2022-11-30 23:59:00,122,124
2022-11-30 23:58:00,113,112
2022-11-30 23:57:00,144,143
2022-11-30 23:56:00,137,138
2022-11-30 23:55:00,119,120
2022-11-30 23:54:00,103,102
2022-11-30 23:53:00,104,105
2022-11-30 23:52:00,143,142
2022-11-30 23:51:00,138,139
2022-11-30 23:50:00,155,153
2022-11-30 23:49:00,100,102

 

timestamp: 2022-11-30 23:59:00

logons: 122

 

here is the spl that i run:
| rex field=_raw "(?<time>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}),(?<logons>\d+)"
| eval _time=strptime(time, "%Y-%m-%d %H:%M:%S")
| timechart span=15m avg(logons) as logons
| fit MLTKContainer algo=stumpy m=96 logons from _time into app:stumpy_anomalies
| table _time logons matrix_profile
| eventstats p95(matrix_profile) as p95_matrix_profile
| eval anomaly=if(matrix_profile>p95_matrix_profile,1,0)
| fields - p95_matrix_profile

 

before fit command _time show correctly, but after fit command it's empty!

FYI: logon, matrix_profile, anomaly return correctly but _time is empty!

 

Any  idea?
