procmeter3 modules - The modules that are used by the procmeter3, gprocmeter3, procmeter3-log and procmeter3-lcd programs.

The ProcMeter3 programs provide a framework that allows displaying of information in various formats. The collection of the data to be displayed is performed by a set of loadable modules.

The modules that are provided with the program are the following:

APM

Advanced Power Management information. These outputs are only available if you have configured the Linux kernel to have the APM feature and you have the appropriate hardware. The outputs can tell you the amount of time remaining and the state of charge of the battery.

Biff

Monitors the e-mail inbox (in /var/spool/mail/<username> or /var/mail/<username> ) and indicates the number of e-mails that are waiting and the size of the inbox. The options parameter in the .procmeterrc file can be used to specify an alternate filename to use for the inbox.

Date_Time

The current date and time and the amount of time since the system was last booted. Different outputs are available that allow the format of the date and time information to be changed. For the time outputs the options parameter in the .procmeterrc file can be set to 12 to indicate that a 12 hour format with AM/PM is to be used.

DiskUsage

Shows the percentage of the disk that is used and the amount of free space for each of the local disks that it finds are mounted or can be mounted when the program starts. Extra disks can be passed as options using the options parameter in the .procmeterrc file to contain a space separated list of mount points.

LogFile

Monitors the size and number of lines and the rate of increase of the size or number of lines in a set of log files. The options parameter in the .procmeterrc file contains a space separated list of log file names.

Memory

The amount of memory that is used for programs, buffers, cache and the amount that is free. This is the same information that is available from the free program, but is available here as a graph, bar or as text.

Network

The network devices and the amount of traffic on each of them. It will automatically pick up available devices when it starts. To specify others use the options parameter in the .procmeterrc configuration file which is a space separated list of device names.

Processes

The load average and the number of processes running and starting.

ProcMeter

Information about the procmeter program itself.

Sensors

Hardware sensors for temperature and fan speed. (Requires kernel patch from http://www.netroedge.com/~lm78/ or version 2.6 kernel or later).

Statistics

Low level system statistics. For example CPU usage, context switches, interrupts, disk usage (before kernel 2.6), swapping and paging (before kernel 2.6).

Stat-CPU

More detailed statistics about individual CPU usage including individual CPU usage for SMP machines.

Stat-Disk

More detailed statistics about individual disk usage read and write. For older linux kernels (before version 2.4) there is only support for up to 4 disks (this limit is set by the kernel and not by procmeter). For version 2.4 or later kernels the limit is removed and the disk names are picked up when the program starts. For version 2.6 or later kernels individual partitions are available. To force other disks to be listed use the options parameter in the .procmeterrc configuration file which is a space separated list of device names (e.g. /dev/fd0).

Stat-Intr

More detailed statistics about individual interrupts including support for up to 32 interrupts (more interrupts may be available from the kernel but not displayed).

Uname

The system information, hostname and Linux kernel version, the same as the output of the uname program.

Wireless

Information about wireless network devices. It will automatically pick up available devices when it starts. To specify others use the options parameter in the .procmeterrc configuration file which is a space separated list of device names.

Longrun

For systems with the Transmeta Crueso processor, information about longrun. Will not work unless the kernel is compiled with CPUID support, and /dev/cpu/0/cpuid must be readable by procmeter. (Allow regular users to access the cpuid device at your own risk!)

ACPI

Advanced Configuration and Power Interface information. These outputs are only available if you have enabled ACPI in the Linux kernel and you have the appropriate hardware. ACPI can report various information about a system's battery, and may also have thermal outputs available.

VM_Statistics

Low level system statistics about virtual memory (swapping and paging) for kernel version 2.6 where the information has moved from the Statistics section.
