Troubleshooting

Autoreduction

• Check that all autoreduction services are up: https://monitor.sns.gov/dasmon/common/diagnostics/

• Examine the autoreduction logs on the analysis cluster: /<facility>/<instrument>/IPTS-XXXX/shared/autoreduce/reduction_log/, see also Autoreduction report.

• Examine the autoreducers logs on the individual autoreducers at /var/log/SNS_applications/postprocessing.log.

• Verify the configuration of the autoreduction workflow at: https://monitor.sns.gov/database/report/task/.

Database view

Users with admin privileges can open the Django admin interface at https://monitor.sns.gov/database/ to view the database tables. Log tables, e.g. “Run status”, may be useful for troubleshooting.
