|
||
安装软件包：`lm-sensors`、`lm-sensors-detect`
|
||
|
||
修改 `/usr/libexec/rpcd/luci` 文件，添加一个 `ubus` 的 `method`：
|
||
<pre style="font-family: 'SF Mono', consolas, Menlo, 'PingFang SC', 'Microsoft YaHei', monospace; font-size: 13px; line-height: 24px; white-space: break-spaces">
|
||
return { result = args.localtime }
|
||
end
|
||
},
|
||
<span style="background: #dfd">
|
||
getCPUInfo = {
|
||
call = function()
|
||
local sys = require "luci.sys"
|
||
local rv = {}
|
||
rv.cpufreq = sys.exec("grep 'MHz' /proc/cpuinfo | cut -c11- | sed -n '1p' | tr -d '\n'")
|
||
rv.cputemp = sys.exec("sensors | grep Core | awk '{print $1,$2,$3}' | tr '\n' ' '")
|
||
return rv
|
||
end
|
||
},
|
||
</span>
|
||
getTimezones = {
|
||
</pre>
|
||
|
||
<!-- more -->
|
||
|
||
修改 `/usr/share/rpcd/acl.d/luci-base.json` ，给刚刚添加的 `getCPUInfo` 添加权限：
|
||
|
||
<pre style="font-family: 'SF Mono', consolas, Menlo, 'PingFang SC', 'Microsoft YaHei', monospace; font-size: 13px; line-height: 24px; white-space: break-spaces">
|
||
"ubus": {
|
||
"file": [ "list", "read", "stat" ],
|
||
"iwinfo": [ "assoclist", "freqlist", "txpowerlist", "countrylist" ],
|
||
"luci": [ "getConntrackList", "getInitList", "getLocaltime", "getProcessList", "getRealtimeStats", "getTimezones", "getLEDs", "getUSBDevices", "getSwconfigFeatures", "getSwconfigPortState", "getBlockDevices", "getMountPoints"<span style="background: #dfd">, "getCPUInfo"</span> ],
|
||
"luci-rpc": [ "getBoardJSON", "getDHCPLeases", "getDSLStatus", "getDUIDHints", "getHostHints", "getNetworkDevices", "getWirelessDevices" ],
|
||
</pre>
|
||
|
||
修改 `/www/luci-static/resources/view/status/include/10_system.js`
|
||
|
||
<pre style="font-family: 'SF Mono', consolas, Menlo, 'PingFang SC', 'Microsoft YaHei', monospace; font-size: 13px; line-height: 24px; white-space: break-spaces">

var callCPUInfo = rpc.declare({

|

return baseclass.extend({

|
||
fs.lines('/usr/lib/lua/luci/version.lua')
|
||
]);
|
||
},
|
||
render: function(data) {
|

var boardinfo = data[0],
|

var fields = [

|

_('Kernel Version'), boardinfo.kernel,
|

_('Local Time'), datestr,
|
||
_('Uptime'), systeminfo.uptime ? '%t'.format(systeminfo.uptime) : null,
|

<span style="background: #dfd"> _('CPU Info'), cpuinfo.cpufreq + ' MHz / ' + cpuinfo.cputemp,</span>
|
||
_('Load Average'), Array.isArray(systeminfo.load) ? '%.2f, %.2f, %.2f'.format(
|
||
systeminfo.load[0] / 65535.0,
|

|
||
systeminfo.load[2] / 65535.0
|
||
) : null
|
||
];
|
||
</pre>
|
||
|
||
使用命令 `/etc/init.d/rpcd restart` 重启 `rpcd` 服务，最后清除浏览器页面缓存。
|
||
|
||
PS：可使用 `ubus call luci getCPUInfo` 检查执行是否有异常。 |
