[Observium] Logging changes to Observium

Is there a way to log who is doing what whithin Observium? I would like to be able to tell who is adding or deleting devices, making changes to the config, or making any changes to Observium for that matter. I am not able (allowed) to lock down the config by making changes in the config.php. I have to keep the configs open to be changed by anyone on the team. This is truthfully a null point as the admin and root passwords are mandated to be stored in our team password vault anyway. I'd like a way to make others accountable for their actions.

Thanks,

Josh
