xx-disconnect-clients-on-ixn-server-disconnect
Section: statserver
Default Value: no
Valid Values: yes, no
Changes Take Effect: After restart
Controls whether Stat Server disconnects all clients—including voice clients—upon receiving notification of disconnection from Interaction Server.
In large environments, setting this option to yes enables Stat Server to handle more efficiently Interaction Server disconnections by ceasing to open new statistics from Stat Server clients—a time-consuming operation in very large environments. It is assumed that you will perform the reconnection after the Interaction Server disconnect has been resolved.
InteractionAbandoned (Tenants)
This retrospective action is unconditionally generated on a Tenant upon receiving the EventAbandoned.
For more information about Stat Server actions, see InteractionAbandoned (Tenants).
qos-recovery-enable-lms-messages
Section: overload
Default Value: false
Valid Values: true, false
Changes Take Effect: After restart
Introduced: 8.5.108
Enables Standard recovery related log messages, which are introduced for debugging purpose:
10072 “GCTI_SS_OVERLOAD_RECOVERY_STARTED - Overload recovery started on %s (%d current CPU usage)”
10073 “GCTI_SS_OVERLOAD_RECOVERY_FAILED - Overload recovery failed on %s (%d current CPU usage)”.
qos-default-overload-policy
Section: overload
Default Value: 0
Valid Values: 0, 1, 2
Changes Take Effect: After restart
Introduced: 8.5.108
Defines the global overload policy.
If this option is set to:
- 0 (zero) - sends and updates for requested statistics can be cut
- 1 - only sends of statistics to Stat Server clients can be cut
- 2 - nothing can be cut. Stat Server updates and sends all requested statistics.
protection
Section: overload
Default Value: false
Valid Values: true, false
Changes Take Effect: Immediately
Introduced: 8.5.108
Controls whether the overload protection is applied during the Stat Server overload.
cut-debug-log
Section: overload
Default Value: true
Valid Values: true, false
Changes Take Effect: Immediately
Introduced: 8.5.108
Controls debug logging in the overload. If set to true, the debug log is cut during the Stat Server overload.
cpu-threshold-low
Section: overload
Default Value: 60
Valid Values: 0-100
Changes Take Effect: After restart
Introduced: 8.5.108
Defines the lower level of the main thread CPU utilization threshold, which signifies the start of the Stat Server recovery.
cpu-threshold-high
Section: overload
Default Value: 80
Valid Values: 0-100
Changes Take Effect: After restart
Introduced: 8.5.108
Defines the higher level of the main thread CPU utilization threshold, which signifies the start of the Stat Server overload.
cpu-poll-timeout
Section: overload
Default Value: 10
Valid Values: 1-60
Changes Take Effect: After restart
Introduced: 8.5.108
Defines, in seconds, how often the main thread CPU is polled.
cpu-cooldown-cycles
Section: overload
Default Value: 30
Valid Values: 1-100
Changes Take Effect: After restart
Introduced: 8.5.108
Defines the number of cpu-poll-timeout cycles in a cooldown period.
For example, if the cpu-poll-timeout = 10sec and cpu-cooldown-cycles = 30, then the cooldown period is 10x30 =300sec. It means that the main thread CPU should be below the value of the cpu-threshold-low option for 300sec, after this period overload recovery is considered to be over.
allow-new-requests-during-overload
Section: overload
Default Value: true
Valid Values: true, false
Changes Take Effect: Immediately
Introduced: 8.5.108
Controls whether new requests can be made during the Stat Server overload.
allow-new-connections-during-overload
Section: overload
Default Value: true
Valid Values: true, false
Changes Take Effect: Immediately
Introduced: 8.5.108
Controls whether new clients can connect during the Stat Server overload.
8.5.108.15

Resolved Issues
This release contains the following resolved issues:
Stat Server now correctly calculates the following statistic:
Category=Formula
Expression=@MAX(CallWait; duration; <user-data dependent expression> )
Objects=Queue
Subject=DNAction
(SS-7896)
Stat Server now correctly calculates filtered Custom Formula statistics, which contain current sub-aggregates (such as @SUM), when Subject=DNStatus. (SS-7881, SS-7880)
Stat Server no longer incorrectly converts non call related ACW to call related ACW upon receiving the EventAddressInfo event, when there are a call and a non call-related ACW in progress. (SS-7874)
Stat Server no longer logs the wrong "Stat Server has removed a stuck call" diagnostic message upon receiving the EventAddressInfo event on a regular DN, when there is a UserEventReceived action in progress on that DN with non-empty ConnID. (SS-7871)
Stat Server now correctly applies the xx-disconnect-clients-on-ixn-server-disconnect option, disconnecting its clients before handling the EventAgentLogout, upon Interaction Server disconnect. (SS-7870)
Stat Server now correctly calculates time-sensitive Custom Formula statistics with Subject=DNStatus|AgentStatus|PlaceStatus. (SS-7834)
Stat Server no longer intermittently terminates unexpectedly on Linux 7 when trying to load multiple Java Extensions at startup. (SS-7799)
Stat Server now reads time-zone objects from the Environment tenant only. Previously, Stat Server read time-zones from all assigned tenants while it only used time-zones that are configured on the Environment tenant. (SS-7710)
Stat Server now correctly evaluates current non-incrementally computable Custom Formula statistics, aggregating on action kv-lists. (SS-7701)
