SysUsage

SysUsage is a system monitoring and alarm reporting tool. The project can generate historical graph views of CPU, memory, IO, network and disk usage, and much more.

USAGE

Once you have correctly installed and configured SysUsage the best way to run it is by croni job. As it is very fast you can set running time each minute. This is the default interval used in the graph report tool sysusagegraph. So I recommand you to do so or to modify this script to match you interval.

Here is how I use it with an installation with all path by default :

*/1 * * * * /INSTALL_DIR/sysusage
*/5 * * * * /INSTALL_DIR/sysusagegraph

If you have change the default installation path (/usr/local/sysusage) you need to give these script the path to the configuration into the command line argument using -c option. To know what arguments can be passed use option -h or --help.

Features:

• Load average.
• CPUs usage. (total, system, user, iowait, idle, steal)
• Memory usage (with and without cache).
• Share memory usage (POSIX /dev/shm).
• Swap usage.
• Page swapping.
• Page I/O stats.
• R/W request stats.
• R/W block stats.
• Created process per second.
• Percentage of open file regarding to file-max.
• Number of socket in use. With TCP versus UDP.
• Any active network interface usage.
• Errors on network interface (bad packet, dropping, collision.
• Any mounted partition disk space usage.
• Monitoring running process.
• Monitoring number of file in queue directory.

What is new in this release:

• Add monitoring of I/O workload and maximum disk throughput per device to help finding where a I/O bottleneck can occur. Allow multiple recipient for alarm report. Alarm on high memory load is know calculated in percentage of real memory used, i-e: without cache and buffer memory usage. See ChangeLog for a complete list of changes.

What is new in version 3.2:

• This release fix a bug in workload notification and add the new 'menu' configuration directive in the PLUGIN section to allow classification of plugins under submenus.

What is new in version 3.1:

• This release include the excellent work of Marat Dyatko on new web design as well some pending bugs fix. There's 2 new configuration options HIRES and LINE_SIZE.

What is new in version 3.0:

• This release is a major code rewriting and features addons. It also include better support to major Linux distribution with RPM, SlackBuild and Debian packaging support. To see all changes take a look at Changelog and the Features menu link.

What is new in version 2.12:

• Fix incorrect warning on socktw report type.
• Add report of the number of active/passive TCP connections per second. See output of "sar -n TCP".
• Add report of the number of receveid/sent TCP segments per second. See output of "sar -n TCP".

What is new in version 2.11:

• Fix memory usage report. Real used memory (without cache) was wrong. Thank to Stephane Silly for the report.
• Add memory cached+kernel buffer report in memory stats.
• Add report of socket in TIME_WAIT state.

What is new in version 2.10:

• Fix missing replacement of underscore in pathname for queue or disk.
• Fix missing prompt on "What device do you want to monitor" question.
• Fix warning when hddtemp is not found during installation.
• Force df to only report local disk usage excluding tmpfs.
• Add monitoring of sensors temperature and fan speed following regexp. See INSTALL file for more details (chap. SENSORS).

What is new in version 2.9:

• This release adds support for versions of sysstat up to 8.1.5.
• Some more system information is reported, like CPU usage for a given device and the amount of memory needed for current workload.
• It also introduce an RPM .spec file given by the Fedora Core team to build distribution packages.
