| <accordion-item title="1. Not working, although everything is installed according to the instructions"> | |
| If you have installed and configured everything according to the instructions, but the “QoE Analytics” section in DPIUI2 is empty, here are the steps to follow before contacting technical support. | |
| |
| - Check the time and timezone settings on the DPIUI2 and QoE Stor servers. Try setting a large period in DPIUI2. If the issue is with the timezone, data will appear. Correct the time settings on the DPIUI2 and QoE Stor servers, and fully restart the servers <wrap em>(If you changed the timezone, you need to [[en:dpi:dpi_components:qoestor:commands:start#delete_db_schema|delete]] and [[en:dpi:dpi_components:qoestor:commands:start#create_update_database_schema|recreate the database schema]])</wrap>. | |
| - On the QoE Stor server, check if the [[en:dpi:dpi_components:qoestor:commands:start#check_if_the_database_has_been_created|database is created]]. If not, [[en:dpi:dpi_components:qoestor:commands:start#create_update_database_schema|create it using the command]]. | |
| - On the QoE Stor server, [[en:dpi:dpi_components:qoestor:commands:start#check_if_there_is_data_in_the_database|check if there is data in the database]]. Alternatively, check how partitions are filling up through the web interface in the QOE ANALYTICS / ADMINISTRATOR / Table Space Information section. | |
| - Check if the [[en:dpi:dpi_components:qoestor:commands:start#check_if_receivers_are_running|receivers are running]] and [[en:dpi:dpi_components:qoestor:commands:start#restarting_receivers_and_configuration|restart the receivers]] if needed. | |
| - On the QoE Stor server, check the receiver logs in the folder ''/var/qoestor/backend/logs''. There should be no errors in the logs. You should see the rotation of dumps and their writing to the database. | |
| - On the QoE Stor server, check if ports 1500 and 1501 are being [[en:dpi:dpi_components:qoestor:commands:start#check_if_the_receivers_are_listening_to_the_ports_and_if_there_is_a_connection|listened to by the receivers]]. | |
| - Restart all receivers as a precaution using the [[en:dpi:dpi_components:qoestor:commands:start#restarting_receivers_and_configuration|command]]. | |
| - Double-check the [[en:dpi:dpi_components:qoestor:configuration:dpi:start|IPFIX export settings on the DPI]]. | |
| - On the DPIUI2 server, check the [[en:dpi:dpi_components:dpiui:configuration:start|GUI connection settings to QoE Stor]]. | |
| - On the QoE Stor server, check if the ClickHouse DBMS is running using the [[en:dpi:dpi_components:qoestor:commands:start#check_if_the_db_is_working|command]]. Ensure there is enough RAM on the server. | |
| - On the QoE Stor server, check the ClickHouse logs: <code bash>/var/log/clickhouse-server/clickhouse-server.err.log</code> | |
| |
| If you need to clear all data in the database, on the QoE Stor server: | |
| - Delete the database using the [[en:dpi:dpi_components:qoestor:commands:start#delete_db_schema|command]]. | |
| - Recreate the database using the [[en:dpi:dpi_components:qoestor:commands:start#create_update_database_schema|command]]. | |
| </accordion-item> | |
| |
| <accordion-item title="2. How to reduce storage period and clear data?"> | |
| Data clearing is performed by the DPIUI2 module. | |
| On the server where DPIUI2 is installed, modify the following parameters in the ''/var/www/html/dpiui2/backend/.env'' file: | |
| <code bash> | |
| QOESTOR_MAIN_LOG_PARTITIONS_LIFE_TIME_HOUR=2 | |
| QOESTOR_AGG_LOG_PARTITIONS_LIFE_TIME_DAYS=15 | |
| </code> | |
| Restart the service: | |
| <code bash>dpiui2 queue:restart</code> | |
