LM Sensors Monitoring Prooblem.

Post by JabawokJayUK »

I am using the following script to monitor my lm sensors:

[root@nukleuz cacti]# cat scripts/check_sensors.pl
#!/usr/bin/perl

@sensoroutput=`/usr/bin/sensors`;

foreach(@sensoroutput) {
chomp();
split();
if ( "$_[0] Temp:" eq 'M/B Temp:' ) {
$temp1 = $_[2];
}
if ( "$_[0] Temp:" eq 'CPU Temp:' ) {
$temp2 = $_[2];
}
if ( $_[0] eq 'Temp3:' ) {
$temp3 = $_[1];
}
if ( $_[0] eq 'fan1:' ) {
$fan1 = $_[1];
}
if ( $_[0] eq 'fan2:' ) {
$fan2 = $_[1];
}
if ( $_[0] eq 'fan3:' ) {
$fan3 = $_[1];
}
}
$temp1 =~ s/\+//;
$temp1 =~ s/\°C//;
$temp2 =~ s/\+//;
$temp2 =~ s/\°C//;
$temp3 =~ s/\+//;
$temp3 =~ s/\°C//;

print "$fan1 $fan2 $fan3 $temp1 $temp2 $temp3\n";

I have created my Input Sources, Input methods & Graphs etc correctley, but my graphs contain no data.

if i run cmd.php from the cmd line this is what i get :

As you can see it is not updating the rra's for the lmsensors, but they do exist:

I am completeley stumped on this and would appreciate any help or advice that you can offer!!!

Ok i have changed my script to output this:

print "rpm1:$fan1 rpm2:$fan2 rpm3:$fan3 temp1:$temp1 temp2:$temp2 temp3:$temp3\n";

which gives this:

rpm1:2220 rpm2:1622 rpm3:3375 temp1:41 temp2:33 temp3:43

But how do i get the rrd update bit sorted?

HELP!!!
You must make a RRD with all six datasources
in Cacti->Data Sources->Your Source
---8<-----8<-----
DS:fan1:GAUGE:600:0:U \
DS:fan2:GAUGE:600:0:U \
DS:fan3:GAUGE:600:0:U \
DS:temp1:GAUGE:600:0:U \
DS:temp2:GAUGE:600:0:U \
DS:temp3:GAUGE:600:0:U \
---8<-----8<-----
(not probed).

But a idea is fans and temperatures in two RRD's.

Hy, I just done that, and suffer a lot to make it work :o))
So I really enjoy to share it !!

Anyway, here's how I did it:

I started with a scripts similar to yours and finally modified it to:

check_sensors.pl
  • @sensoroutput=`/usr/bin/sensors`;

    foreach(@sensoroutput) {
    chomp();
    split();
    if ( $_[0] eq 'Vcore:' ) {
    $Vcore = $_[1];
    }
    if ( $_[0] eq '3.3V:' ) {
    $V33V = $_[1];
    }
    if ( $_[0] eq '5V:' ) {
    $V5V = $_[1];
    }
    if ( $_[0] eq '12V:' ) {
    $V12V = $_[1];
    }
    if ( $_[0] eq 'CPU_Fan:' ) {
    $CPUFan = $_[1];
    }
    if ( $_[0] eq 'PWR_Fan:' ) {
    $PWRFan = $_[1];
    }
    if ( $_[0] eq 'SYS_Temp:' ) {
    $SYSTemp = $_[1];
    }
    if ( $_[0] eq 'CPU_Temp:' ) {
    $CPUTemp = $_[1];
    }
    }
    $CPUTemp =~ s/\+//;
    $CPUTemp =~ s/\°C//;
    $SYSTemp =~ s/\+//;
    $SYSTemp =~ s/\°C//;

    print "Vcore:$Vcore V33V:$V33V V5V:$V5V V12V:$V12V CPUFan:$CPUFan PWRFan:$PWRFan SYSTemp:$SYSTemp CPUTemp:$CPUTemp\n";
In the Data Input Methods, I created a new one with the Fields like this:

Data Input Methods [edit: Get LM Sensors]
Name: Get LM Sensors
Input Type: Scripts/Command
Input String: perl /usr/share/cacti/scripts/check_sensors.pl

Input Fields Add
Name Field Order Friendly Name
No Input Fields

Output Fields Add
Name Field Order Friendly Name Update RRA
V33V 0 (Not In Use) 3.3 V Selected
VCore 0 (Not In Use) Core Voltage Selected
V5V 0 (Not In Use) 5 V Selected
V12V 0 (Not In Use) 12 V Selected
CPUFan 0 (Not In Use) CPU Fan speed Selected
PWRFan 0 (Not In Use) Mobo Fan Speed Selected
SYSTemp 0 (Not In Use) Mobo Temperature Selected
CPUTemp 0 (Not In Use) CPU Temperature Selected

After that, it's the same as your's, the Data sources you created must have ont Data Source Item per mesurement, each one mapped on one output fields that is available.

I hope it will help you !!

If anyone have a trick so that I can convert this one to Template without losing the existing mesures, I could post the XML file there.
