| ====== 6 Problems and solutions ====== | |
| {{indexmenu_n>6}} | |
| |
| ==== Doesn't work, although everything was installed according to the instructions ==== | |
| |
| If you installed and configured everything according to the instructions, and the DPIUI2 “QoE Analytics” section is empty, then here is a list of steps you should follow before contacting those. support. | |
| |
| - Check the correct time and timezone settings on servers with dpiui2 and QoE Stor. Try setting a large period in dpiui2. If the matter is in the time zone, the data will appear. Set the time correctly on the dpiui2 and QoE Stor servers, restart the servers completely (<color #ed1c24>If the timezone has been changed the database must be [[en:dpi:dpi_components:qoestor:commands:start#удалить_схему_бд|deleted]] and [[en:dpi:dpi_components:qoestor:commands:start#создать_обновить_схему_бд|recreated]]</color>). | |
| - On the server with QoE Stor check [[en:dpi:dpi_components:qoestor:commands:start#проверить_создана_ли_бд|if the database has been created]]. If the database is not created [[en:dpi:dpi_components:qoestor:commands:start#создать_обновить_схему_бд|create it with the command]]. | |
| - On the server with QoE Stor check [[en:dpi:dpi_components:qoestor:commands:start#проверить_есть_ли_данные_в_бд|if there is data in the database]]. Or see how the partitions are filled through the web interface in the QOE ANALYTICS / ADMINISTRATOR / Tablespace Information section. | |
| - Check [[en:dpi:dpi_components:qoestor:commands:start#проверить_запущены_ли_ресиверы|if receivers are running]] amd [[en:dpi:dpi_components:qoestor:commands:start#перезапуск_ресиверов_и_конфигурации|restart receivers]] if required. | |
| - On the server with QoE Stor check the receiver logs in the folder <code>/var/qoestor/backend/logs</code> There should be no errors in the logs. The rotation of the dumps and their writing to the database should be visible. | |
| - On the server with QoE Stor check [[en:dpi:dpi_components:qoestor:commands:start#проверить_слушают_ли_ресиверы_порты_и_есть_ли_соединение|if ports 1500 and 1501 are listening]]. | |
| - Restart all receivers just in case [[en:dpi:dpi_components:qoestor:commands:start#перезапуск_ресиверов_и_конфигурации|with the command]]. | |
| - Check [[en:dpi:dpi_components:qoestor:configuration:dpi:start|the ipfix dpi export settings]] again. | |
| - On the server DPIUI2 check [[en:dpi:dpi_components:dpiui:dpiui2#настройка_подключения_к_qoe_stor|the settings for connecting the GUI to the QoE Stor]]. | |
| - On the server with QoE Stor check if the ClickHouse is running [en:dpi:dpi_components:qoestor:commands:start#проверить_работает_ли_бд|with the command]]. Make sure there is enough RAM on the server. | |
| - Check the log on the server with QoE Stor <code>/var/log/clickhouse-server/clickhouse-server.err.log</code> | |
| |
| If there is a need to clear all data in the database, then on the server with QoE Stor you need | |
| - Delete database [[en:dpi:dpi_components:qoestor:commands:start#удалить_схему_бд|with command]]. | |
| - Recreate the database [[en:dpi:dpi_components:qoestor:commands:start#создать_обновить_схему_бд|with command]]. | |
| |
| ==== How to reduce retention period and clear data ==== | |
| |
| Data cleaning is performed by the dpiui2 module. | |
| On the server where dpiui2 is installed change the parameters in the <code>/var/www/html/dpiui2/backend/.env</code> file | |
| <code> | |
| QOESTOR_MAIN_LOG_PARTITIONS_LIFE_TIME_HOUR=2 | |
| QOESTOR_AGG_LOG_PARTITIONS_LIFE_TIME_DAYS=15 | |
| </code> | |
| Restart | |
| <code>dpiui2 queue:restart</code> | |
