Description

TECHNICAL FIELD Embodiments presented in this disclosure generally relate to monitoring and assessing device performance in a network. More specifically, embodiments disclosed herein are related to monitoring a performance of a device over a deployment of the device in a network and using the monitored performance to generate baseline performance expectations for the device. BACKGROUND Optical and electronic devices deployed in a network are often hot pluggable or swappable devices that are easily removed and replaced by a network operator. While these devices are monitored at a network level, existing failure predictors utilize measurements related to real-time network effects and implementation of the network devices. In these examples, monitoring is focused on preventing any failures and outages of in the overall optical network and not directed to individual device performance. Moreover, once a deployment of a device is ended and the device is dismantled or removed from the network, access to monitoring data is often either no longer available or is not available in a format that aids deployment-agnostic analysis of the device performance. This absence of device specific monitoring data prevents a fabricator or network operator from properly assessing device performance and may also lead to devices being decommissioned before a service life of the device is met. Device specific monitoring and assessment for devices in a network deployment remains a challenge.
