# System Maintenance

This section describes the configurations of performance monitoring, operation log dumping, antiDDoS data maintenance, and system backup.

- AntiDDoS1820-N Performance Monitoring
  You can view the CPU usage and interface traffic statistics through AntiDDoS1820-N performance monitoring.
- Anti-DDoS Device Performance Monitoring
  You can view the CPU usage and interface traffic statistics.
- Router Performance Monitoring
  You can view the CPU usage and interface traffic statistics of a router through router performance monitoring.
- Performance Monitoring
  Monitoring the system performance means monitoring the server and database information. You can monitor system performance by setting usage thresholds for all items of the server, to discover and rectify anomalies as soon as possible and optimize system operating.
- Dumping the Operation Logs
  After you set the interval for dumping operation logs, the system will automatically dump the operation logs and traffic diversion logs from the ATIC management center to the specified directory on the ATIC management center server at specified intervals and reduce the recording times of the database and improve the ATIC management center operating efficiency.
- Dumping the Alarms
  When the number of past alarms stored in the ATIC Management center database exceeds the threshold, the ATIC Management center performance will be affected or the ATIC Management center will break down even. Dumping the alarms dumps the events and the past alarms in a file to the specified folder, reducing the burden of the ATIC Management center and improving the ATIC Management center performance. The alarm dump function enables the ATIC Management center to dump the events and historical alarm data in the database as files to the specified folder, which improves the ATIC Management center operating performance.
- Service Data Maintenance
  This section describes how to maintain anti-DDoS data by setting appropriate data reservation duration to ensure high resource usage.
- Backing Up Configuration Files
  This section describes how to back up system configurations.
- HA
  This section describes how to perform an HA switchover.
