# slmon(1)

program for monitoring system's performance in realtime.

## NAME

slmon - program  for  monitoring system's performance in realtime.

## SYNOPSIS

**slmon** \[options\]

## DESCRIPTION

**SLmon** is a tool for monitoring system's performance. It displays results using nice and (hopefully) readable text-based UI. Currently monitored are:

- o

  CPU load (SMP is supported)

- o

  network interfaces

- o

  memory (including swap)

- o

  uptime, date and time

- o

  number of logged in users

- o

  mounted filesystems

- o

  processes

**SLmon** uses *glibtop* version \>= 2 and *libslang* version \>= 1.2.2 (this version however has a bug that makes it impossible to write a character in lower right corner, but otherwise it works okay).

Starting with 0.5.13 *Glib* library is needed.

## OPTIONS

- \-v, --version

  Display version and copying and exit

- \-h, --help

  Display brief usage information

- \-f, --fs-unit=\[kmg\]

  Specify filesystem usage unit, where: b=bytes, k=kbytes, m=mbytes, g=gbytes

- \-m, --mem-unit=\[bkmg\]

  Specify memory usage unit, where: b=bytes, k=kbytes, m=mbytes, g=gbytes

- \-n, --net-unit=\[bkmg\]

  Specify network traffic unit, where: b=bytes, k=kbytes, m=mbytes, g=gbytes

- \-d, --mode=\[mpnh\]

  Start in mode 'M' where: m=main, p=process, n=network, h=histogram

- \-u, --update=\<seconds\>

  Specify update interval in seconds

## Configuration files

SLmon looks for the configuration file in the following locations:

- /etc/slmonrc

  - /usr/local/etc/slmonrc

  if the previous one fails

- $HOME/.slmonrc

  Options can be specified in the form of pairs: *\<key\> = \<value\>*. Lines beginning with '#' are treated as comments (note: all leading whitespaces are stripped). All subsequent definitions of a certain option overwrite previous declarations except for the *net\_dev* option.

Available options (more to come :)):

- mode

  Start certain mode: m=main, p=process, n=network, h=histogram.

- mem\_unit

  Specify memory usage unit \[bkm\].

- fs\_unit

  Specify filesystem usage unit \[kmg\].

- net\_unit

  Specify network traffic unit \[bkmg\].

- net\_dev

  Add a network interface to list of monitored interfaces.

- update\_time

  Specify update interval in seconds.

## FILES

/etc/slmonrc ~/.slmonrc Files with user defined options
