This configuration parameter specifies the size, in KB, of disk space available for the local cache that should generate a warning message. The agent will check the availability of free disk space at the interval specified with the adclient.disk.check.interval parameter. If the disk space available at any interval is less than the value you set for the adclient.disk.check.free parameter, the agent stops saving data in the local cache and displays a warning message to indicate that you should free up disk space. At the next interval when the available disk space exceeds the size you set for this parameter, the agent resumes normal operation and saving data to its cache.
In most cases, you set this configuration parameter using group policy. You can, however, set it manually in the configuration file if you are not using group policy or want to temporarily override group policy.
The parameter value must be an integer of zero or greater. A value of zero disables the display of a warning message about the available disk space. The default minimum of available disk space that triggers a warning message is 51200 KB. For example:
Note: Keep in mind that the value you set for this parameter can affect the recovery of a system. The agent will only resume saving data in its local cache if there is more disk space available than what you have specified to generate the warning. For example, if you have specified that the agent issue a warning when the available disk space falls to 51200 KB, there must be more than 51200 KB of disk space available for the agent to return to normal operation and write to the cache.
