EZZ8661I
TRMD TCP QOS exception log records suppressed:time,lhost=lhost,port=port,count=count,scope=scope,probeid=probeid,
sensorhostname=sensorhostname

Explanation

To prevent syslog flooding, Intrusion Detection Services (IDS) logging was suppressed for log message EZZ9318I (QOS exceptions). Traffic regulation (TR) support for TCP limits the number of EZZ9324I (TCP connection refused), EZZ9319I (TCP connection would have been refused) and EZZ9318I (QOS exception) log records written in a 5-minute interval. For a listening port, a maximum of 100 of these log records will be written in a 5-minute interval. Across all ports monitored by TCP TR, a maximum of 1000 of these log records will be written in a 5-minute interval.

time is the date and time of the first log record suppressed for the port in the 5 minute interval.

lhost is the IP address of the local host.

port is the listening port for which log suppression occurred.

count is the number of EZZ9318I log messages suppressed during the 5 minute interval.

scope is either:
Port
The log records were suppressed because 100 log records had already been written for the listening port in the 5-minute interval.
TR
The log records were suppressed because the total number of TCP TR log records written during the 5-minute interval exceeded 1000 log records.

probeid is the unique identifier of the probe detection point. See the intrusion detection services probeids in z/OS Communications Server: IP and SNA Codes for a description of the IDS probe IDs.

sensorhostname is the fully qualified host name of the IDS sensor.

System action

TCP/IP processing continues. TCP TR logging resumes.

Operator response

None.

System programmer response

Examine relevant syslog messages to determine the source of the log entries and take appropriate action: adjust the active policy to be less restrictive or investigate the logged QOS exceptions.

Module

EZATRMD

Procedure name
