#base_ejection_time ⇒ Google::Apis::ComputeAlpha::Duration
A Duration represents a fixed-length span of time represented as a count of
seconds and fractions of seconds at nanosecond resolution. It is independent
of any calendar and concepts like "day" or "month". Range is approximately 10,
000 years.
Corresponds to the JSON property baseEjectionTime

#consecutive_errors ⇒ Fixnum
Number of errors before a host is ejected from the connection pool. When the
backend host is accessed over HTTP, a 5xx return code qualifies as an error.
Defaults to 5.

#consecutive_gateway_failure ⇒ Fixnum
The number of consecutive gateway failures (502, 503, 504 status or connection
errors that are mapped to one of those status codes) before a consecutive
gateway failure ejection occurs. Defaults to 3.

#enforcing_consecutive_errors ⇒ Fixnum
The percentage chance that a host will be actually ejected when an outlier
status is detected through consecutive 5xx. This setting can be used to
disable ejection or to ramp it up slowly. Defaults to 0.

#enforcing_consecutive_gateway_failure ⇒ Fixnum
The percentage chance that a host will be actually ejected when an outlier
status is detected through consecutive gateway failures. This setting can be
used to disable ejection or to ramp it up slowly. Defaults to 100.

status is detected through success rate statistics. This setting can be used
to disable ejection or to ramp it up slowly. Defaults to 100.

#interval ⇒ Google::Apis::ComputeAlpha::Duration
A Duration represents a fixed-length span of time represented as a count of
seconds and fractions of seconds at nanosecond resolution. It is independent
of any calendar and concepts like "day" or "month". Range is approximately 10,
000 years.
Corresponds to the JSON property interval

#max_ejection_percent ⇒ Fixnum
Maximum percentage of hosts in the load balancing pool for the backend service
that can be ejected. Defaults to 50%.
Corresponds to the JSON property maxEjectionPercent

# File 'lib/google/apis/compute_alpha/classes.rb', line 28665 def max_ejection_percent @max_ejection_percent end |
#success_rate_minimum_hosts ⇒ Fixnum
The number of hosts in a cluster that must have enough request volume to
detect success rate outliers. If the number of hosts is less than this setting,
outlier detection via success rate statistics is not performed for any host
in the cluster. Defaults to 5.
Corresponds to the JSON property successRateMinimumHosts

# File 'lib/google/apis/compute_alpha/classes.rb', line 28673 def success_rate_minimum_hosts @success_rate_minimum_hosts end |
#success_rate_request_volume ⇒ Fixnum
The minimum number of total requests that must be collected in one interval (
as defined by the interval duration above) to include this host in success
rate based outlier detection. If the volume is lower than this setting,
outlier detection via success rate statistics is not performed for that host.
Defaults to 100.
Corresponds to the JSON property successRateRequestVolume

#success_rate_stdev_factor ⇒ Fixnum
This factor is used to determine the ejection threshold for success rate
outlier ejection. The ejection threshold is the difference between the mean
success rate, and the product of this factor and the standard deviation of the
mean success rate: mean - (stdev * success_rate_stdev_factor). This factor is
divided by a thousand to get a double. That is, if the desired factor is 1.9,
the runtime value should be 1900. Defaults to 1900.
Corresponds to the JSON property successRateStdevFactor
