Parameter | Description |
|---|---|
Type | The type of the event log. Each type has separate configuration parameters and logs to a separate file. |
State |
...
Specifies the requested state of the given |
...
event log type.
Accounting logs cannot be disabled. | |
File Count | The number of event log files that will be maintained for this event type. All event types will overwrite the oldest file when the file count is exceeded. A warning will be issued when the count approaches the maximum. Enter a value between the range |
...
1 and 2048. | |
File Size | The maximum size (in KB) that a single event log file will ever grow to. Enter a value between in the range (256 |
...
-65535) KB. File size should be set to 65535 for trace and account logs when trying to trace all the calls on the system for use with Protect. | |
Message Queue Size | The number of event log message entries to buffer before writing them to disk. The size may be a value between 2 and |
...
100. The default is 10. If capturing all of the SIP PDU messages in the trace log for use with Protect, set this value to 100 for the trace log. | |
Save To | Save events. The values are:
|
...
| |
Filter Level | The filter severity level of events. Events that are at least as severe as the designated level will be logged. |
...
Noevents suppresses all events of this type from being logged. |
Rollover Start Time |
...
Specifies the start |
...
time for event log rollover. The format is CCYY-MM-DDTHH:MM:SS. For example: 2010-01-01T01:01:01. | |
Rollover Interval | Enter the number of seconds |
...
for the event log rollover interval. |
Rollover Type |
...
Event log rollover type. |
...
Options are:
| |
Rollover Action | Event log rollover actions. The values are:
|
File Write Mode | Identifies event log NFS write mode. The values are: |
...
|
...
|
Syslog State |
...
Specifies whether the contents of this log are also written out to the syslog
...
Syslog Remote host
...
Specifies the remote host where the messages are written to the syslog. This must be a valid host name or a valid IP address.
...
Syslog Remote Protocol
...
Specifies the protocol to use to send messages to the remote syslog.
...
Syslog Remote Port
...
The IP Port Number. Specifies the port to use to send messages to the remote syslog.
Enable this option to log events of specified type to syslog.

Rename Open Files | Enable this option to append an ".OPEN" extension to accounting and files which are open for writing.
NOTE: You must enable the Signaling Packet Capture State parameter to capture SIP and H.323 packets (refer to Call Trace and Packet Capture - Signaling Packet Capture for configuration details). Once Signaling Packet Capture State is enabled, any subsequent changes tothe SBC device configurations or filter information will not be available to signaling packet captures until the state is reset (state is disabled, and then re-enabled). |
| Disk Throttle Limit | Specifies the limit on INFO level messages logged to the disk in one second. A value of 0 disables the limit. The default is 5000 and the value can go up to 4,294,976,295. For the trace log, if tracing is being performed to capture all of the SIP PDU for all of the calls on the system for use in conjunction with Protect, then this value needs to be tuned to accommodate the maximum call load anticipated for the SBC instance. For example, for a call rate of 1350 cps and assuming 14 messages in a basic SIP call (ingress and egress legs), it would require a total of 18,900 messages. Adding this to the default 5000, the recommendation in this case would be to set the limit at 25,000. |
| Event Log Validation | Specifies whether the logs at rest for this log type should be cryptographically hashed. The values are:
Hashing is only recommended for the security and audit logs. These are the main logs required to triage security issues and do not roll very frequently. IMPORTANT: You must disable this control for any logs which are rolling at a very high rate, for example, if capturing trace logs of all SIP PDUs for use with Protect. If logs are being exported using Rsyslog then there is no need to enable Event Log Validation as the logs are copied off the SBC before they could be modified. Refer to OAM - Event Log - Platform Rsyslog |
