Configuring How and When GTM Saves Configuration Changes
Overview: Configuring how and when GTM saves configuration changes
By default, BIG-IP® Global Traffic Manager™ (GTM™) automatically saves GTM configuration changes 15 seconds after the change is made in either the Configuration utility or tmsh. You can change how long GTM waits before it saves GTM configuration changes. In addition, you can disable automatic saves of GTM configuration changes, but then you must run a command in tmsh to save those changes. All changes to the GTM configuration are stored in the bigip_gtm.conf file.
Task summary
Perform one of these tasks to configure how and when the BIG-IP system saves GTM configuration changes.
Changing the automatic configuration save timeout
Ensure that GTM™ is provisioned on the device.
You can change how long the BIG-IP system waits to save the GTM configuration
following a GTM configuration change. For example, if you are making many changes to the
GTM configuration at one time, you might want to extend the Configuration
Save Timeout to allow you to complete more changes before the GTM
configuration is saved.
The BIG-IP system waits the specified number of seconds before saving GTM
configuration changes to the stored configuration.
Enabling manual saves of configuration changes
Ensure that GTM™ is provisioned on the device.
You can disable automatic saves of GTM configuration changes when you want to have
strict control over when GTM configuration changes are saved to the stored
configuration. CPU usage can be affected simply by saving small changes to a large
configuration.
Configuring how and when GTM saves configuration changes using tmsh
Ensure that GTM™ is provisioned on the device, and that your
user role provides access to tmsh.
By default, the BIG-IP® system automatically saves GTM
configuration changes made in the Configuration utility and tmsh. You
can change how long the system waits to save GTM configuration changes. You can also
configure the system for manual saves that require you to run a tmsh
command to save GTM configuration changes.
GTM waits the number of seconds you specify before saving GTM configuration changes.
If you specified -1, then you must save the configuration
manually using this command: tmsh save sys config gtm-only partitions
