The following Short Term Canister thresholds are compared with the Canister statistics that are polled by the Statistics service and stored in shared memory. This polling occurs every 30 seconds.
If any of these thresholds is breached, the Capture Socket service stops sending hits to the
Canister and begins queuing hits. If the CanCheckEventLog setting is ON, messages
appear in the event application log when a Canister threshold has been exceeded.
Note: These threshold settings must take into account the size of the systems on which they are
installed. Thresholds that are set too low cause the Canister to stop accepting hits too often and
interrupt traffic flow. Thresholds that are too high may cause data to overflow the Canister
memory.
- Display Name values are displayed in TMS, which is the recommended method for configuring session agents.
- Name values are displayed in
TealeafCaptureSocket.cfg.
| Display Name | Name | Description |
|---|---|---|
Canister Check |
Cancheck |
Enables checking of the Canister. |
Canister Logging |
CanCheckLog |
Outputs Canister statistics to a log file whose location is specified by the LogDir setting |
Canister Max % Memory Used |
CanCheckMaxCtreeMemUsedPct |
Maximum allowed percentage of memory allocated by the Canister Server. When set to 0, the cache value is ignored, and the CanCheckMinCtreeMemUsedPct setting is also ignored. |
Canister Min % Memory Used |
CanCheckMinCtreeMemUsedPct |
Specifies the minimum percentage of FairCom Cache in use.
|
Max Unevaluated Canister Hits |
CanCheckMaxUnevalHits |
If the number of un-evaluated hits in the Canister exceeds this number, the Canister health is compromised. |
Min Unevaluated Canister Hits |
CanCheckMinUnevalHits |
Specifies the minimum number of unevaluated hits. When the maximum value is reached, the Extended Decoupler queues hits until the minimum value is reached. If CanCheckMaxUnevalHits is set to 0, this setting is ignored. |
Max Sessions Waiting for LTC |
CanCheckMaxSesnWaitForLtc |
If the number of sessions waiting to be archived exceeds this value, the Canister health is compromised. |
Min Sessions Waiting For LTC |
CanCheckMinSesnWaitForLtc |
Specifies the minimum threshold of sessions waiting to be archived. When the maximum threshold has been exceeded, Extended Decoupler queues until the minimum number has been reached. |
Max Sessions Waiting For IDX |
CanCheckMaxSesnWaitForIdx |
If the number of sessions waiting to be indexed exceeds the specified number, the Canister health is compromised. |
Min Sessions Waiting for IDX |
CanCheckMinSesnWaitForIdx |
Specifies the minimum threshold of sessions waiting to be indexed. When the maximum threshold has been exceeded, Extended Decoupler queues until the minimum number has been reached. |
Drain STC on Error |
CanCheckDrainSTCOnError |
When a maximum threshold is surpassed, the Extended Decoupler signals to the Canister to close all sessions and drain the Canister without waiting for the session timeout. The default value is OFF. |
