Final answer:
The default downtime limit for Splunk offline is not fixed and can be configured by administrators using parameters such as auto_restart_after_secs in the server.conf file, tailored to specific system requirements.
Step-by-step explanation:
The default downtime limit for Splunk offline mode is not predefined as it primarily depends on the specifics of the deployment and the configurations set by the administrator. However, Splunk provides parameters to configure the limits for downtime in several scenarios, mainly through the server.conf and indexes.conf files. For instance, the auto_restart_after_secs setting in server.conf can be used to restart Splunk after a specified number of seconds of being offline. It is important for administrators to configure these settings in accordance with their system requirements and the expected tolerance for downtime.
