Lists the APIC upgrade logs location and file structure for monitoring upgrade progress.
Beginning in software release 4.0, the upgrade logs (installer logs) for the APICs have been moved to a user accessible location to allow for live consumption. They can be opened or tailed to determine if the APIC upgrade is proceeding as expected. Depending on the upgrade jump, there will be either one or two log files to encompass the entire upgrade process.
The file that is always expected will have a name similar to insieme_*_installer.log, and for upgrades starting with 4.x there will be an additional atom_installer.log. In all version scenarios, the insieme_*_installer.log should be checked first, as this log will have a message indicating when it has invoked the atom_installer which then logs to the atom_installer.log.
The log files are stored in the /firmware/logs/YYYY-MM-DDTHH-MM-SS-MS directory on each APIC, where the timestamp of the folder corresponds to the timestamp where that specific upgrade was triggered.

atom_installer.log
insieme_4x_installer.log In the example above, a recent upgrade was triggered on May 28, 2021 around 10:18. The corresponding log files are contained within that directory. The individual log files can be opened with your linux file viewer of choice for content viewing. If instead the goal is to watch the logs live to ensure an upgrade is still in-progress, issue a tail –f insieme_zx_installer.log to view the content as its being written to the log file in real time.
