Node Clinic is a suite of diagnostic tools for Node.js applications, designed to help developers identify and resolve performance issues, memory leaks, and other common problems in their code.

CAT is a distributed application performance monitoring and alerting system that specializes in tracking request flows, exceptions, and metrics across microservice ecosystems. It offers real-time dashboards showing throughput, response times, error rates, and service dependency graphs to help operations and development collaborate on reliability issues. In addition to metrics, it enables tracing—propagating context across RPC boundaries so problems like latency spikes or failed calls can be traced end-to-end. Alert rules and anomaly detection can be defined to notify teams proactively. The system supports multiple data backends and ingestion pipelines to collect data from JVM, C/C++, Python, and other ecosystems. ...

...It provides developers and system administrators with tools to trace performance bottlenecks, memory usage, request distribution, regex execution, Lua execution, and file I/O behaviors in production systems. The toolkit helps identify leaks, analyze TCP queues, inspect shared memory usage, and generate flame graphs for CPU and off-CPU profiling. Many scripts are specific to NGINX worker and master processes, while others are generic enough to be applied to any Linux user-space process. Although the toolkit is no longer actively maintained—development has shifted to OpenResty XRay—it remains a valuable set of examples and utilities for advanced users of OpenResty and NGINX.

cpuplot Command Line Profiler of CPU Usage and Load Average. Synopsis: BASH script that shows the history of CPU usage, and what procces uses the most CPU at a given time. Bar graphs represent the percentage of Total CPU Usage, and the percentage of Total 1 Minute Load Average. Default wait interval between system readings is 5secs. But a different one can be set in the command line with the "-i" argument. Default output is formatted for the standard console width of 80 columns, and will show only the bar chart for the CPU usage. ...

It's a very light Redhat Linux and Oracle OVM System Performance Monitoring tool written in Perl using rrdtool for Database and Graphing. Allows you to query the RRD database given a set of dates and generates a web based graphs. Easy to install. Uses less disk space than most performance monitoring tool. Data of each host monitored is kept for 2 years and occupy less that 25 MB of disk space.

jLlama is a desktop application to monitor servers over SSH. Any figure retrieved from the command line can be polled and graphed in real time. Out of the box, jLlama can graph CPU and Memory usage for Linux and Solaris servers.

Simple tool to parse the contents of /proc or /sys entries and graph their values. An oscillosope for software types. Intended for developers, admins or the curious to understand the performance and behaviour of their systems.
