Logging statistics
Since build 5.2.1210 it is possible to get logging statistics, that may be useful on the server under high load
| Code Block | ||||
|---|---|---|---|---|
| ||||
curl -s 'http://localhost:8081/?action=stat&groups=log_stats' |
The following parameters are included
| Code Block | ||
|---|---|---|
| ||
-----Logger info-----
log_msg_per_sec=0.30
log_mbit_per_sec=0.00 |
- log_msg_per_sec - logging messages count (all logs) per second
- log_mbit_per_sec - logging volume (all logs) in megabits per second
For example, statistics is buffered on 10 seconds interval. If there is no any message logged during this interval, the statistic values are cleaned. The interval can be set by the following parameter
| Code Block | ||
|---|---|---|
| ||
log_metrics_time_buffer=10000 |
The interval cannot be set less than 1 second, the default value will be used in such case.
