Feature overview: Inbound performance optimization
How to configure: Inbound performance optimization configuration
4.10.1 irpinperfd.enabled #
Enables or disables the inbound performance feature.
Refer to: Inbound performance optimization
- Possible values:
0 (Disabled), 1 (Enabled) - Default value:
0
4.10.2 irpinperfd.log #
Defines the path to the log file in the server file-system.
- Default value:
/var/log/irp/irpinperfd.log
4.10.3 irpinperfd.log.level #
Defines the logging level for the Irpinperfd service.
- Possible values:
emerg, fatal, alert, crit, error, warn, notice, info, debug, trace - Default value:
info
4.10.4 irpinperfd.model.debug #
Enables additional logging of Inbound Performance statistical model.
- Possible values:
0 (Disabled), 1 (Enabled) - Default value:
0
4.10.5 irpinperfd.model.shelf_life #
The value indicates the time interval (in seconds) for which the calculated model will be used, after which the model will be recalculated.
- Possible values:
7220-43200 - Default value:
7220
4.10.6 irpinperfd.model.stability_interval #
Time interval (in seconds) for algorithm to gather data to evaluate how many prefixes from the model have recorded traffic.
- Possible values:
1800-3600 - Default value:
1800
4.10.7 irpinperfd.model.topn_per_rule #
The number of top volume prefixes to be analyzed per an inbound performance rule.
Increasing this value may raise the accuracy of improvements at the expense of the probing slots.
- Possible values:
1-1000 - Default value:
200
4.10.8 irpinperfd.moderated #
Enables or disables the moderated mode of handling inbound improvements.
- Possible values:
0 (Disabled), 1 (Enabled) - Default value:
0
4.10.9 irpinperfd.probing.confirmation_interval #
The time interval (seconds) between two probings of the sample prefixes for active rules.
- Possible values:
3600-86400 - Default value:
18000
4.10.10 irpinperfd.probing.failure_margin #
The value indicates the minimal acceptable percentage of the failed probes.
- Possible values:
0-25 - Default value:
10
4.10.11 irpinperfd.probing.interval #
Time interval (seconds) between two probings of the sample prefixes.
- Possible values:
300-5400 - Default value:
600
4.10.12 irpinperfd.probing.shelf_life #
The value indicates how much time (seconds) the probe will be actual for inbound performance improvement.
- Possible values:
30-3600 - Default value:
600
4.10.13 irpinperfd.probing.timeout #
Defines the waiting time (seconds) of the probing results. Probing result absence will lead to the algorithm restarts if probing is not finished within the configured time period.
- Possible values:
120-900 - Default value:
600
4.10.14 irpinperfd.rtt_allowed_worsening #
Defines the maximum allowed worsening of RTT per probe. After rule activation, if a significant number of probes will experience worsening of RTT greater than this value, the improvement will be removed.
- Possible values:
1-1000 - Default value:
10
