Which of the following are typical tools used for logging and monitoring in cloud environments?

• A. Only CloudWatch is used.
• B. Prometheus and Grafana are not suitable for cloud-native.
• C. Stackdriver is obsolete.
• D. Tools include CloudWatch, Stackdriver/Cloud Monitoring, Prometheus, Grafana, ELK/Splunk; set alerts and dashboards.

Answer: (D)

In cloud environments, you observe and respond to the health and performance of systems by using a mix of tools that handle metrics, logs, alerts, and visual dashboards. Relying on a single tool almost never covers all data sources across different clouds and on‑prem components. That’s why typical setups include cloud-native services like AWS CloudWatch, which collects metrics and logs from AWS resources and can trigger alerts and dashboards, and Google Cloud’s monitoring (the successor to Stackdriver), which provides similar capabilities for Google Cloud resources.

At the same time, teams often add open‑source or third‑party solutions to cover multi‑cloud or heterogeneous workloads. Prometheus is widely used for scraping and storing metrics from services, especially in Kubernetes environments, with Alertmanager handling alerting rules. Grafana complements these by offering rich, unified dashboards that can pull data from Prometheus and many other sources. For centralized logging and advanced search/analysis, the ELK stack (Elasticsearch, Logstash, Kibana) or Splunk are common choices. Bringing these tools together lets you correlate metrics and logs across clouds and on‑prem, enabling effective monitoring and rapid incident response.

So, the best answer reflects this practical landscape: a suite of tools including CloudWatch, Cloud Monitoring (Stackdriver), Prometheus, Grafana, and ELK or Splunk, all used with alerts and dashboards to monitor cloud environments. The other statements are too limiting or outdated: only one tool is rarely sufficient; Prometheus and Grafana are indeed suitable for cloud‑native setups; Stackdriver isn’t obsolete, it’s rebranded as Cloud Monitoring; and you typically deploy multiple tools to cover all data sources and use cases.
