📄️ Data ImportThere are multiple ways of importing data provided by TDengine: import with script, import from data file, import using taosdump.

📄️ TDengine MonitoringAfter TDengine is started, it automatically writes monitoring data including CPU, memory and disk usage, bandwidth, number of requests, disk I/O speed, slow queries, into a designated database at a predefined interval through taosKeeper. Additionally, some important system operations, like logon, create user, drop database, and alerts and warnings generated in TDengine are written into the log database too. A system operator can view the data in log database from TDengine CLI or from a web console.
