SetErrorFilter(filters)

Examples

• Filter common errors.

  • javascript
  • python
  • rust
  • cpp

  
      javascript
      
      
  function main() {
      SetErrorFilter("502:|503:|tcp|character|unexpected|network|timeout|WSARecv|Connect|GetAddr|no such|reset|http|received|EOF|reused")
  }
  

  
      python
      
      
  def main():
      SetErrorFilter("502:|503:|tcp|character|unexpected|network|timeout|WSARecv|Connect|GetAddr|no such|reset|http|received|EOF|reused")
  

  
      rust
      
      
  fn main() {
      SetErrorFilter("502:|503:|tcp|character|unexpected|network|timeout|WSARecv|Connect|GetAddr|no such|reset|http|received|EOF|reused");
  }
  

  
      c++
      
      
  void main() {
      SetErrorFilter("502:|503:|tcp|character|unexpected|network|timeout|WSARecv|Connect|GetAddr|no such|reset|http|received|EOF|reused");
  }
  

• Filter error messages from a specific interface.

  • javascript
  • python
  • rust
  • cpp

  
      javascript
      
      
  function main() {
      // Query a non-existent order (id 123) to deliberately trigger an interface error
      var order = exchange.GetOrder("123")
      Log(order)
      // Filter http 502 errors and GetOrder interface errors; after setting the error filter, the second call to GetOrder will no longer report an error
      SetErrorFilter("502:|GetOrder")
      order = exchange.GetOrder("123")
      Log(order)
  }
  

  
      python
      
      
  def main():
      order = exchange.GetOrder("123")
      Log(order)
      SetErrorFilter("502:|GetOrder")
      order = exchange.GetOrder("123")
      Log(order)
  

  
      rust
      
      
  fn main() {
      // Query a non-existent order (id 123) to deliberately trigger an interface error
      let orderId = OrderId { S: "123".to_string(), ..Default::default() };
      let order = exchange.GetOrder(&orderId);
      Log!(order);
      // Filter http 502 errors and GetOrder interface errors; after setting the error filter, the second call to GetOrder will no longer report an error
      SetErrorFilter("502:|GetOrder");
      let order = exchange.GetOrder(&orderId);
      Log!(order);
  }
  

  
      c++
      
      
  void main() {
      TId orderId;
      Order order = exchange.GetOrder(orderId);
      Log(order);
      SetErrorFilter("502:|GetOrder");
      order = exchange.GetOrder(orderId);
      Log(order);
  }
  

Arguments

Remarks

Error logs that match this regular expression will no longer be uploaded to the logging system. This function can be called multiple times (with no limit on the number of calls) to set multiple filter conditions; regular expressions set across multiple calls accumulate and take effect simultaneously. You can pass an empty string to reset the regular expression used to filter error logs: SetErrorFilter(""). Filtered logs will no longer be written to the database file corresponding to the live trading Id under the docker directory, thereby preventing the database file from bloating due to frequent errors.
