Logs for local-db-publisher

Hello,

These events will be stored in /var/log based on event type... Posting some document excerpts below, let me know if this helps. 

 

local-syslog     Causes the system to store log messages in the local Syslog database. When you choose this log destination, the BIG-IP Configuration utility displays the log messages in these categories: System, Local Traffic, Global Traffic, and Audit.

local-db   Causes the system to store log messages in the local MySQL database.

When you choose local-db, the BIG-IP Configuration utility does not display the log messages.

 

For local log messages that the BIG-IP system stores in the local Syslog data base, the BIG-IP system automatically stores and displays log messages in these categories:

• System messages
• Packet filter messages
• Local Traffic messages
• Global Traffic messages
• BIG-IP system configuration (audit) messages

Each type of event is stored locally in a separate log file, and the information stored in each log file varies depending on the event type. All log files for these event types are in the directory /var/log.

 

GTM is the older product name that was used with older TMOS versions.  GTM is the correct logfile in this case.  Typically you would not want to log every query/response as it does have performance impact to your system.  Configuring BIG-IP DNS to log dns queries and responses (f5.com).  

To log query/responses here are some quick instructions extracted from that KB article above:

Creating a custom DNS logging profile for logging DNS queries and responses

Create a custom DNS logging profile to log both DNS queries and responses when troubleshooting a DDoS attack.

Note: Logging both DNS queries and responses has an impact on the BIG-IP system performance.

1. On the Main tab, click DNS > Delivery > Profiles > Other > DNS Logging or Local Traffic > Profiles > Other > DNS Logging. The DNS Logging profile list screen opens.

2. Click Create. The New DNS Logging profile screen opens.

3. In the Name field, type a unique name for the profile.

4. From the Log Publisher list, select a destination to which the BIG-IP system sends DNS log entries.

5. For the Log Queries setting, ensure that the Enabled check box is selected, if you want the BIG-IP system to log all DNS queries.

6. For the Log Responses setting, select the Enabled check box, if you want the BIG-IP system to log all DNS responses.

7. For the Include Query ID setting, select the Enabled check box, if you want the BIG-IP system to include the query ID sent by the client in the log messages.

8. Click Finished.
