public sealed class MetricsPolicy| MetricsPolicy | Default constructor. |
| MetricsPolicy(MetricsPolicy) | Copy constructor. |
| Interval | Number of cluster tend iterations between metrics notification events. One tend iteration is defined as {@link ClientPolicy#tendInterval} (default 1 second) plus the time to tend all nodes. Default: 30 |
| LatencyColumns | Number of elapsed time range buckets in latency histograms. Default: 7 |
| LatencyShift |
Power of 2 multiple between each range bucket in latency histograms starting at column 3. The bucket units
are in milliseconds.The first 2 buckets are <=1ms and >1ms. Examples:
{@code
// latencyColumns=7 latencyShift=1
<=1ms >1ms >2ms >4ms >8ms >16ms >32ms
// latencyColumns=5 latencyShift=3
<=1ms >1ms >8ms >64ms >512ms
}
Default: 1
|
| Listener |
Listener that handles metrics notification events. The default listener implementation
writes the metrics snapshot to a file which will later be read and forwarded to
OpenTelemetry by a separate offline application.
The listener could be overridden to send the metrics snapshot directly to OpenTelemetry. |
| ReportDir | Directory path to write metrics log files for listeners that write logs. Default: current directory |
| ReportSizeLimit |
Metrics file size soft limit in bytes for listeners that write logs.
When reportSizeLimit is reached or exceeded, the current metrics file is closed and a new metrics file is created with a new timestamp.If reportSizeLimit is zero, the metrics file size is unbounded and the file will only be closed when {@link com.aerospike.client.AerospikeClient#disableMetrics()} or TODO { link com.aerospike.client.AerospikeClient#close()} is called. Default: 0 |
