Object storage cloud is widely used to store unstructured data like photo, emails, video etc. generated from use of digital technologies. The number of object storage services has increased rapidly over the years and so is increased the complexity of the infrastructure behind it. Effective and efficient monitoring is constantly needed to properly operate and manage the complex object storage infrastructure. Ceph is an open source cloud storage platform that provides object storage as a service. Several works have discussed ways to collect the data for monitoring. However, there is little mention of what needs to be monitored. In this paper, we provide an infrastructure monitoring list for Ceph object storage cloud. We analyze the Ceph storage infrastructure and its processes for identifying the proposed lists. The infrastructure monitoring list allows selecting requirements, in contrast to, specifying fresh requirements, for monitoring. The monitoring list helps developer during requirement elicitation of the monitoring functionality when developing a new tool or updating an existing one. The checklist is also useful during monitoring activity for selecting parameters that need to be monitored by the system administrator.
