Embodiments of the present disclosure include systems and methods for determining readiness for switchover operations for network devices. A policy definition specifying a set of criteria and a set of instructions is received. Based on the set of instructions, a first supervisor module is determined whether it is ready for a switchover operation based on the set of criteria. The switchover operation includes a second supervisor module configured as a backup to the first supervisor module taking over for the first supervisor module. A set of conditions are determined whether they are satisfied. When the set of conditions are determined to be satisfied and the first supervisor module is determined to be ready for the switchover operation, the switchover operation is triggered to cause the second supervisor module to take over for the first supervisor module.

Determining readiness for switchover operations for network devices

In some implementations, a method is provided. The method includes detecting a reboot of a network device. The method also includes determining a set of causes for a reboot of the network device. The method further includes updating a reboot log to include a first entry associated with the reboot of the network device. The first entry indicates the set of causes for the reboot of the network device. The reboot log includes a plurality of previous entries. The plurality of previous entries are associated with previous reboots of the network device. The plurality of previous entries indicates previous sets of causes for the previous reboots of the network device.
