# Example queries for ALB connection logs
<a name="query-alb-connection-logs-examples"></a>

The following query count occurrences where the value for `tls_verify_status` was not `'Success'`, grouped by client IP address:

```
SELECT DISTINCT client_ip, count() AS count FROM alb_connection_logs
WHERE tls_verify_status != 'Success'
GROUP BY client_ip
ORDER BY count() DESC;
```

The following query searches occurrences where the value for `tls_handshake_latency` was over 2 seconds in the specified time range:

```
SELECT * FROM alb_connection_logs
WHERE 
  (
    parse_datetime(time, 'yyyy-MM-dd''T''HH:mm:ss.SSSSSS''Z') 
    BETWEEN 
    parse_datetime('2024-01-01-00:00:00', 'yyyy-MM-dd-HH:mm:ss') 
    AND 
    parse_datetime('2024-03-20-00:00:00', 'yyyy-MM-dd-HH:mm:ss') 
  ) 
  AND 
    (tls_handshake_latency >= 2.0);
```
