Collectl is a light-weight performance monitoring tool capable of reporting interactively as well as logging to disk. It reports statistics on cpu, disk, infiniband, lustre, memory, network, nfs, process, quadrics, slabs and more in easy to read format.
Real-time analysis and diagnostics tools for OpenResty
...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 Although the toolkit is no longer actively maintained—development has shifted to OpenResty XRay—it remains a valuable set of examples and utilities for advanced users of OpenResty and NGINX.
sarPplot simple application which takes output of atsar application and put it into Gnuplot config files , kind of useful on server boxes for performance analyze . cpu,process load,disk,disk-partition,memory & swap,paging & swapping, and many others...
Pscope is a process analyzer that delves deep into every proccess (PID) on a Linux system and provides details such as paging, memory, and CPU utilization. Used with a tool such as sar, pscope helps identify what pids correlate to system usage.

psmon is a *NIX process monitoring daemon which may optionally be run as a standalone program. Allows slaying and respawning of critical processes which die, or exceed pre-determined TTL, concurrent instances and or memory or CPU usage. Supports syslog a
sysprofd is a system profiling daemon that can report results through a tcp connection to a remote client. sysprofd profiles cpu, memory, and swap usage statistics, process status statistics e.t.c. Imagine using it to easily monitor lots of linux boxes
process checker. to kill or/and display any high cpu or mem processes
with command line options. can be run on a crontab and can email
you of the high cpu/mem.
The purpose of snmpwatch is to remotely watch via SNMP the size and
the memory used by each process. Snmpwatch will warn you if a process
exceeds its `quota' of CPU or memory, theses limits are based on
process and host name.
