Attributes

The following table describes attributes for the overload-protection-service element.

Table 1–142 overload-protection-service Attributes


Attribute	Default	Description
`enabled`	`false`	If `true`, the overload protection manager is enabled and operates according to `cpu-overload-protection`, `memory-overload-protection`, and other `overload-protection-service` attributes. Overload regulation protects the HTTP container from too high CPU or memory usage.
`cpu-overload-protection`	`false`	If `true`, CPU overload protection is enabled. Applicable only if `enabled` is set to `true`.
`memory-overload-protection`	`false`	If `true`, memory overload protection is enabled. Applicable only if `enabled` is set to `true`.
`cpu-http-threshold`	`70`	Specifies the CPU usage threshold level for HTTP requests. Allowed values are `0` to `100`. Any SIP requests received when the system is operating beyond this threshold are responded to with a `503` error. Applicable only if `cpu-overload-protection` is set to `true`.
`mem-http-threshold`	`85`	Specifies the memory usage threshold level for HTTP requests. Allowed values are `0` to `100`. Any SIP requests received when the system is operating beyond this threshold are responded to with a `503` error. Applicable only if `memory-overload-protection` is set to `true`.
`cpu-mm-threshold`	`99`	Specifies the CPU usage threshold level when all messages are dropped. Allowed values are `0` to `100`. Applicable only if `cpu-overload-protection` is set to `true`.
`mem-mm-threshold`	`99`	Specifies the memory usage threshold level when all messages are dropped. Allowed values are `0` to `100`. Applicable only if `memory-overload-protection` is set to `true`.
`sample-rate`	`2`	Specifies the sample rate in seconds for updating threshold levels. Allowed values are `1` to `120` seconds.
`number-of-samples`	`5`	Specifies the number of consecutive samples needed before a threshold is raised. Allowed values are `2` to `20`.
`retry-after-interval`	`10`	Specifies the interval in seconds between response retries. This is part of the `retry-after` header in a `503` response.
`cpu-overload-activation-algorithm`	`MEDIAN`	Specifies the activation algorithm for CPU overload protection. Allowed values are `MEDIAN` and `CONSECUTIVE`.
`cpu-overload-deactivation-algorithm`	`CONSECUTIVE`	Specifies the deactivation algorithm for CPU overload protection. Allowed values are `MEDIAN` and `CONSECUTIVE`.
`mem-overload-activation-algorithm`	`MEDIAN`	Specifies the activation algorithm for memory overload protection. Allowed values are `MEDIAN` and `CONSECUTIVE`.
`mem-overload-deactivation-algorithm`	`CONSECUTIVE`	Specifies the deactivation algorithm for memory overload protection. Allowed values are `MEDIAN` and `CONSECUTIVE`.
`mm-threshold-http-wait-time`	`2`	Specifies the time in seconds for which a thread is held before being released back to the thread pool. Used in the context of maximum overload for HTTP requests.
