Performance Co-Pilot (PCP) is a framework and services to support system-level performance monitoring and performance management.
The services offered by PCP are especially attractive for those tackling harder system-level performance problems. For example this may involve a transient performance degradation, or correlating end-user quality of service with platform activity, or diagnosing some complex interaction between resource demands on a single system, or management of performance on large systems with lots of "moving parts".
The distributed PCP architecture makes it especially useful for those seeking centralized monitoring of distributed processing (e.g. in a cluster or webserver farm environment), especially where a large number hosts are involved.
Main features:
- A single API for accessing the performance data that hides details of where the data comes from and how it was captured and imported into the PCP framework.
- A client-server architecture allows multiple clients to monitor the same host, and a single client to monitor multiple hosts (e.g. in a Beowulf cluster). This enables centralized monitoring of distributed processing.
- Integrated archive logging and replay so a client application can use the same API to process real-time data from a host or historical data from an archive.
- The framework supports APIs and configuration file formats that enable the scope of performance monitoring to be extended at all levels.
- An "plugin" framework (libraries, APIs, agents and daemon) to collect performance data from multiple sources on a single host, e.g. from the hardware, the kernel, the service layers, the application libraries, and the applications themselves.
- Libraries and sample implementations encourage the development of new "plugins" (or agents) to capture and export the performance data that matters in your application environment, along side the other generic performance data.
- An endian-safe transport layer for moving performance metrics between the collector and the monitoring applications over TCP/IP. This means an IRIX desktop with PCP can monitor one or more Linux systems with the Open Source release of PCP installed.
- A Linux agent that exports a broad range of performance data from most kernels circa 2.0.36 (RedHat 5.2) or later. This includes coverage of activity in the areas of: CPU, disk, memory, swapping, network, NFS, RPC, filesystems and all the per-process statistics.
- Other agents export performance data from:
- Web server activity logs
- arbitrary application-level tracing (via a PCP trace library)
- Cisco routers
- sendmail
- the mail queue
- the PCP infrastructure itself
- Assorted simple monitoring tools that use the PCP APIs to retrieve and display either arbitrary performance metrics, or specific groups of metrics (as in pmstat a cluster-aware vmstat lookalike).
- The PCP inference engine supports automated monitoring through a rule-based language and interpreter that performs user-defined actions when rule predicates are found to be true.

compact system monitor is a small and compact system monitor for SuperKaramba.

Credit where credit is due, i think i stole the icons from Borealis? Nice are they not? And the idea from someone else.

The theme can be changed somewhat by editing the theme and comenting out some lines.

Hope you like it! Its my first!

Skipole Network Monitor project is a simple network monitor with built in web server.

It allows the user to input host IP addresses, it then pings these hosts every five minutes and displays their status via a built-in web server, on port 8000.

So calling http://your_pc_address:8000 will display pages showing green, yellow or red host or group symbols.

Each host is pinged four times every five minutes, and symbols are displayed as:

green : if three or four pings are successfull
yellow : if only one or two are successfull
red : if all four fail

As well as hosts, group symbols are displayed, and can be opened to show hosts, or sub-groups nested within. The operator can create groups, and sub-groups via the gui.

System Health Monitor for Linux is a handy python program that will setup your system to generate RRD Graphs of network interface traffic, system load, memory usage, disk space and inode usage and graphs of the number of running processes.

System Health Monitor features a user-friendly interactive configuration mode and auto-generated html pages. Just point your web server to the health_html directory to get an overview of the status of your machine. You can see examples of it in operation here on my machine and on KPLUG.org

Linux Kernel Monitor is a tool for monitoring and managing linuxs kernel. It has been developed for GNOME, using Glib and Gtk libraries in C language.
lkmonitor tries to offer detailed information of the characteristics of the system, as type of cpu, state of the memory or the file system registered in kernel.
lkmonitor is an open source project with information about the source code and software architecture to make easy the development of new characteristics.
Enhancements:
- IO information, kernel information, networking info, processes specific information, filesystems, modules, etc.
