Based on this topic
Code
http://forums.openmediavault.org/viewtopic.php?f=13&t=79I created a template to graph the RPi SoC temperature.
First of all
Code
nano /var/www/openmediavault/js/omv/module/admin/Sensors.js
and put inside
Code
/**
* Sensors plugin for system information.
*/
// require("js/omv/NavigationPanel.js")
// require("js/omv/PluginMgr.js")
// require("js/omv/data/DataProxy.js")
// require("js/omv/data/Store.js")
// require("js/omv/grid/TBarGridPanel.js")
// require("js/omv/RrdGraphPanel.js")
Ext.ns("OMV.Module.Diagnostics.SysInfo");
/**
* @class OMV.Module.Diagnostics.SysInfo.Temperatures
* @derived Ext.TabPanel
*/
OMV.Module.Diagnostics.SysInfo.Temperature = function(config) {
var initialConfig = {
title: "CPU temperature",
rrdGraphName: "sensors"
};
Ext.apply(initialConfig, config);
OMV.Module.Diagnostics.SysInfo.Temperature.superclass.constructor.call(
this, initialConfig);
};
Ext.extend(OMV.Module.Diagnostics.SysInfo.Temperature, OMV.RrdGraphPanel, {
});
OMV.preg("sysinfo", "system", OMV.Module.Diagnostics.SysInfo.Temperature);
Then you have to create another file to get your changes in to collectd.conf and omv-mkgraph:
Code
nano /usr/share/openmediavault/scripts/collectd.d/sensors
and put inside
Bash
#!/bin/sh
set -e
. /etc/default/openmediavault
. /usr/share/openmediavault/scripts/helper-functions
OMV_COLLECTD_CONFIG=${OMV_COLLECTD_CONFIG:-"/etc/collectd/collectd.conf"}
OMV_COLLECTD_RRDTOOL_MKGRAPH=${OMV_COLLECTD_RRDTOOL_MKGRAPH:-"/usr/sbin/omv-mkgraph"}
cat <<EOF >> ${OMV_COLLECTD_CONFIG}
LoadPlugin sensors
EOF
cat <<EOF >> ${OMV_COLLECTD_RRDTOOL_MKGRAPH}
# Read temperature from sensor
tempread=\`cat /sys/class/thermal/thermal_zone0/temp\`
tempread=\$((\$tempread/1000))
value=\`echo \$tempread | cut -c -4\`
# Update database

#0000FF means blue trace color in the graphs.
EOFCode
cd /var/lib/collectd/rrd/localhost
Then you have to create the temperature database
Code
nano createrrd.shand put inside
Bash
#!/bin/bash
rrdtool create database.rrd --start N --step 300 \
DS:value:GAUGE:600:U:U \
RRA:AVERAGE:0.5:1:12 \
RRA:AVERAGE:0.5:1:288 \
RRA:AVERAGE:0.5:12:168 \
RRA:AVERAGE:0.5:12:720 \
RRA:AVERAGE:0.5:288:365 \
RRA:MIN:0.5:1:12 \
RRA:MIN:0.5:1:288 \
RRA:MIN:0.5:12:168 \
RRA:MIN:0.5:12:720 \
RRA:MIN:0.5:288:365 \
RRA:MAX:0.5:1:12 \
RRA:MAX:0.5:1:288 \
RRA:MAX:0.5:12:168 \
RRA:MAX:0.5:12:720 \
RRA:MAX:0.5:288:365
Afterwards you have to make it executable
Code
chmod +x createrrd.shand then run it
Code
./createrrd.sh. This should create a file inside the folder named database.rrd. which will store all the temp data. After that, log in the webgui, go to the System information-> System->Temperature tab. After some minutes you should get you SoC temp
The next step is to graph also the CPU freq parallel to the temp graph (for those who overclocked the SoC)
