20.5. Suppressing Repetitive Log Messages

Repetitive log messages in the Red Hat Gluster Storage Server can be configured by setting a log-flush-timeout period and by defining a log-buf-size buffer size options with the gluster volume set command.
Suppressing Repetitive Log Messages with a Timeout Period

To set the timeout period on the bricks:
Copy to Clipboard Toggle word wrap 
# gluster volume set VOLNAME diagnostics.brick-log-flush-timeout <value>

Example 20.13. Set a timeout period on the bricks

Copy to Clipboard Toggle word wrap 
# gluster volume set testvol diagnostics.brick-log-flush-timeout 200
volume set: success
To set the timeout period on the clients:
Copy to Clipboard Toggle word wrap 
# gluster volume set VOLNAME diagnostics.client-log-flush-timeout <value>

Example 20.14. Set a timeout period on the clients

Copy to Clipboard Toggle word wrap 
# gluster volume set testvol diagnostics.client-log-flush-timeout 180
volume set: success
To set the timeout period on glusterd:
Copy to Clipboard Toggle word wrap 
# glusterd --log-flush-timeout=<value>

Example 20.15. Set a timeout period on the glusterd

Copy to Clipboard Toggle word wrap 
# glusterd --log-flush-timeout=60
Suppressing Repetitive Log Messages by defining a Buffer Size

The maximum number of unique log messages that can be suppressed until the timeout or buffer overflow, whichever occurs first on the bricks.

To set the buffer size on the bricks:
Copy to Clipboard Toggle word wrap 
# gluster volume set VOLNAME diagnostics.brick-log-buf-size <value>

Example 20.16. Set a buffer size on the bricks

Copy to Clipboard Toggle word wrap 
# gluster volume set testvol diagnostics.brick-log-buf-size 10
volume set: success
To set the buffer size on the clients:
Copy to Clipboard Toggle word wrap 
# gluster volume set VOLNAME diagnostics.client-log-buf-size <value>

Example 20.17. Set a buffer size on the clients

Copy to Clipboard Toggle word wrap 
# gluster volume set testvol diagnostics.client-log-buf-size 15
volume set: success
To set the log buffer size on glusterd:
Copy to Clipboard Toggle word wrap 
# glusterd --log-buf-size=<value>

Example 20.18. Set a log buffer size on the glusterd

Copy to Clipboard Toggle word wrap 
# glusterd --log-buf-size=10

Note

To disable suppression of repetitive log messages, set the log-buf-size to zero.
