Subject: Added a new filter which can directly read the output
X-Git-Tag: V0_0_11~16

Added a new filter which can directly read the output
of the UNIX df command. A brief description is added in
the user manual.

 <section>
+<heading>System resources</heading>
+<para>
+By monitoring the resources of a system, such as memory, cpu, file systems and
+network interfaces, you can keep track on the system's performance and capacity.
+The utilization of these resources varies frequently over time.
+Viewing the values of resource properties provides an excelent insight in
+the system's behaviour.
+Gnucomo can maintain  a record of the system resources by using DYNAMIC properties
+in parameters.
+You can define classes of parameters with properties that will reflect the state
+of your systems and feed the numbers into the Gnucomo database by using scripts
+that extract the information from a system and convert this into XML format.
+</para>
+<para>
+As an example, consider the processing load of a system.
+Two metrics can be of interest to keep an eye on the system load:
+The total number of processes and the number of runnable processes.
+These numbers are easily obtained with standard UNIX commands <code>ps</code>
+and <code>uptime</code>.
+To maintain this in Gnucomo, a <emph>class</emph> is needed to define the
+properties we want to maintain.
+For this example, we create a class <strong>systemload</strong> with the properties
+<strong>processes</strong> and <strong>runqueue</strong>.
+Note that both these properties are DYNAMIC.
+The properties for the <strong>systemload</strong> class can be defined by using
+Gnucomo's web interface or typing SQL statements directly into the database:
+</para>
+<verbatim>
+INSERT INTO parameter_class (name, property_name, description, property_type, min, max, notify)
+  VALUES ('systemload', 'processes', 'Total number of processes', 'DYNAMIC', 0, 1000, 'f');
+INSERT INTO parameter_class (name, property_name, description, property_type, min, max, notify)
+  VALUES ('systemload', 'runqueue', '5 minute average length of the run queue', 'DYNAMIC', 0, 5.00, 'f');
+</verbatim>
+<para>
+When the class is defined in the Gnucomo database, we are ready to feed the
+information into Gnucomo through <code>gcm_input</code>.
+The following shell script will create the appropriate XML document with the
+parameter values:
+</para>
+<verbatim>
+#!/bin/sh
+#
+# Gnucomo system load report.
+#
+# Create a parameter report with two values:
+# The total number of processes and the 5-min load average.
+# 
+
+
+HOST=`hostname`
+TIME=`date`

+echo "&lt;/gcmt:parameter&gt;"
+
+echo "    &lt;/gcmt:parameters&gt;"
+echo "   &lt;/gcmt:data&gt;"
+echo "&lt;/gcmt:message&gt;"

+<para>
+Filesystems are predefined in Gnucomo.
+Gcm_input understands the output of most <code>df</code> implementations directly.
+The following examples show how to feed filesystem information into Gnucomo:
+</para>
+<example>
+df -lPk -x tmpfs | gcm_input -h `hostname`
+df -lPi -x tmpfs | gcm_input -h `hostname`
+</example>
+<para>
+Make sure to add the <code>-k</code> option so <code>df</code> reports
+the filesystem sizes in kilobytes.
