Question - What do you mean by cloud usage monitor?
Answer -
A cloud usage monitor is a lightweight, autonomous program situated on a cloud that aids in monitoring resources and collecting and processing resource usage data.
There are three standard agent-based implementations of the usage monitor as follows.
- Monitoring agent: responsible for transparent monitoring and analysis of the data flow. It is an event-driven program that resides on the existing communication paths. It aids in measuring network traffic and metrics.
- Polling agent: responsible for gathering cloud service usage data by polling The resources. It also monitors the resource status and forwards usage data to log databases for reporting and post-processing purposes.
- Resource agent: processing models that collect data using event-driven interactions with resources. It aids in checking the usage metrics based on pre-defined, tangible events, like initiation, suspension, resumption, and scaling of resources.
