6 Universal Monitoring Dockapp.
14 5. filesystems - space utilization
16 7. wireless link quality
18 9. CPU temperature, fan speed, voltages (no lm_sensors required!)
19 10. battery status (with actual - not guessed - discharge rate!)
20 11. traffic from your router
23 The dockapp is configured via ~/.wmsupermon file,
24 which specifies what to monitor and how to present the results.
26 The syntax of a config file is:
27 =========================
29 Source = /proc/meminfo
30 Regex = {MemTotal: *([0-9]+).*MemFree: *([0-9]+).*Buffers: *([0-9]+) kB.Cached: *([0-9]+)}[(\1 - \2 - \3 - \4)/\1]s
33 Source = /proc/diskstats
34 #major minor name rio rmerge rsect ruse wio wmerge wsect wuse running use aveq
35 # note that "name" part is limited to letters!
36 # thus we count, e.g. "sda" line, but not "sda1", "sda2", etc.
37 Regex = /^ +[0-9]+ +[0-9]+ [a-z]+ ([0-9]+) [0-9]+ [0-9]+ [0-9]+ ([0-9]+) /DIFF(SUM(\1+\2))/
40 Source = !/usr/local/bin/check_email
45 Regex = {cpu ([0-9]+) ([0-9]+) ([0-9]+) ([0-9]+)}{DIFF(\1+\2+\3+0.01)/DIFF(\1+\2+\3+\4+0.01)}
48 Source = /sys/bus/i2c/drivers/w83627hf/9191-0290/temp2_input
60 =========================
62 Empty lines are allowed, if the line starts with #, it is ignored.
64 First there are sources of readings. Every source starts with a label
65 (e.g. [mem]) which can be one to three characters long.
67 After the label, the following keywords are allowed:
69 Source = specifies where to take the data from. It's either a
70 filename or an executable/script (if the value starts from the
73 Regex = defines how to parse the source (the file or the output of
74 an executable). It consists of two parts delimited by any non-blank
75 character (e.g. regex= !...!...! or /..../..../) or two pairs of
76 matching brackets (e.g. [ ...]{...} or (...)<....>).
77 The first part is an extended regex, the second - an expression to
78 evaluate. This expression can use numeric constants (floating
79 point), \1 .. \9 to refer to parts of regex, operators + - * / > < ?:,
80 parentheses, and two functions SUM() and DIFF().
82 The DIFF function (which means differentiate) returns the difference
83 between the value of its argument and the value of its argument from
84 the previous evaluation. See [cpu] source above to for an example -
85 DIFF is used to convert the constantly growing number of raw "cpu
86 ticks" into "cpu usage".
88 The SUM() function is explained below.
90 After the expression one can put flags. Supported are
91 i - case insensitive match
92 s - single line (see below)
93 d - debug (the result of the expression is printed to stdout).
95 Normally the source is read line by line, until the regex matches
96 for the first time. The result of the expression is the reading of
99 If SUM() function is present anywhere in the expression, all lines
100 of the source are read, and all matches are accumulated. The result
101 of the SUM() is the sum of values of its argument for all matches.
102 See [i/o] source above for an example - SUM is used to calculate i/o
103 for all block devices.
105 If 's' (single line) flag is specified, regex is used to match
106 file's content as a whole, not linewise. See [mem] source above for
109 If no regex is specified, the source is expected to contain just one
110 number (many files on sysfs do).
112 Other recognized keywords are:
114 Interval = N, the reading of a source is taken every N seconds. 0
115 means "as fast as possible" (currently - four times a second).
117 Scale = N, the reading calculated from Source+Regex is divided by N.
118 That's most useful when there's no regex, see [Tem] example above.
120 Range = N1 .. N2, used by bar and graph widgets. Without explicit
121 range, bar expect readings to be in 0..1 range, and graph
122 autoscales. As with scale, this is most useful when no regex is
123 specified, as in [Tem] example above.
125 Action = shell command to be executed on left mouse click on the
128 Besides sources, config file defines windows and panes.
130 Every window definiftion starts from [[name]], where "name" is the
131 window title. Wmsupermon may open many windows, with different
132 layouts and values to monitor.
134 Window definition consists of widgets, which are placed on panes. A
135 pane has four rows, and a widget can take up to all the four,
136 depending on the type and options, see below. A pane is thus defined
137 by one to four lines, specifying widgets for this pane. Empty
138 lines are used to separate panes. One widget line looks like
140 name=widget [options]
142 where <name> is the name of a source, defined above, and <widget> is
143 the widget type. Supported widget types are "number", "percent",
144 "bar", and "graph". After the type, one can optionally put
145 <options>, from the following list:
147 -label - print a source name on the widget.
148 can be used with any widget
149 -smooth - smooth the output by averaging last 8 readings.
150 can be used with any widget
151 -float - print a number with the decimal dot, not an integer.
152 can be used only with "number" widget
153 -log - use logarithmic scale. only valid for "graph" widgets
154 -big - 4-rows graph, only valid for "graph" widgets
155 -medium - 2-rows graph, only valid for "graph" widgets
156 -small - 1-row graph, only valid for "graph" widgets.
157 by default a graph takes 3 rows.
158 -scaledown - if the graph autoscales, allow the scale to decrease,
159 by default it can only increase.
