This notification is issued when ccsSessionThresholdNotifEnabled is set to 'true', and when the number of sessions exceeds warning threshold or critical threshold or drops below the normal threshold. The critical threshold limit is 100% of ccsgsSessionThreshold. The warning threshold limit takes a default value of 85% of ccsgsSessionThreshold, which can be reconfigured in the application code via a CLI. The normal threshold limit is 5% less than the warning threshold. When the number of sessions in the system increases and reaches the warning threshold, a warning notification is sent. When the number of sessions again increases to reach the critical threshold, a critical notification is sent. When it drops below normal threshold, a normal notification is sent. ccsgsSessionCurrent indicates the total number of sessions on the system. A session corresponds to a TCP/UDP flow. ccsgsSessionThreshold indicates the maximum number of sessions allowed on the system. ccsgUserSessionSeverityNotifInfo indicates the severity of the notifications ciscoContentServicesUserEntriesThreshold and ciscoContentServicesSessionThreshold. The TP index responsible for the threshold crossing is specified by the ccsTPIndexNotifInfo varbind
