Cloud application performance monitoring tools are utilized to gather an extensive range of metrics and logs from cloud resources and services. Some commonly monitored metrics include CPU utilization, memory usage, network traffic, disk I/O, latency, and response time. By monitoring these metrics, among others, it becomes possible to gain insights into resource utilization, identify performance bottlenecks, and ensure that the infrastructure operates according to expectations. An application's performance may be degraded if CPU utilization consistently exceeds a certain threshold, for example. The monitoring of metrics helps administrators identify such issues and take appropriate action, such as provisioning additional resources or optimizing application code.

Monitoring cloud service logs is also crucial to understanding the behaviour and health of cloud-based systems. A system log often contains valuable information regarding system events, errors, warnings, and security-related activities. Monitoring logs enables the detection and investigation of anomalies, issue resolution, and identification of root causes. By analyzing application logs, it is possible to identify specific errors encountered by users or uncover patterns that may indicate potential performance or security weaknesses. This allows for a proactive approach to addressing and resolving problems.

In general, cloud monitoring provides organizations with visibility, insights, and control over their cloud infrastructure and applications. By proactively monitoring and analyzing metrics, logs, and security events, organizations can ensure optimal performance, address issues promptly, and enhance the overall reliability and security of their cloud environment.

Throughout this article, we will examine the most commonly used tools for cloud monitoring.

4. Nagios


Among open-source monitoring systems, Nagios is widely used. The software monitors hosts, services, and network devices in a variety of environments. Both active and passive monitoring methods are supported by Nagios. In active monitoring, resources are monitored actively via probes or agents, while in passive monitoring data is gathered from external sources such as log files or SNMP traps. Plugins in Nagios allow integration with different technologies and systems to monitor diverse metrics. With Nagios, users can set thresholds, escalation procedures, and notification preferences.

5. Icinga

Icinga is an open-source monitoring platform forked from Nagios. It builds upon the Nagios core while introducing new features and improvements. For large environments, Icinga offers a scalable and distributed architecture. Cloud resources, network devices, host services, and network devices can all be monitored. Icinga supports both agent-based and agentless data collection methods. Metrics can be collected and processed from a variety of sources with the help of plugins. Using Icinga, users can define checks, notifications, and dependencies according to their needs.

These previously named open-source cloud monitoring tools provide organizations with powerful and flexible options for monitoring their cloud infrastructure, applications, and services. As we move forward, we will discuss the leading SaaS solutions for cloud monitoring.
