If like me, you don't have an eth0 or an hda, it's nice to change the R5E50 rrdtool setup so it reflects your system.
The data collection files to change are in /usr/local/bin/rrdtool_*.pl
The web page files to change are in /var/www/rrdtool_*.html.
For me I have a wireless connection so I modified /usr/local/bin/rrdtool_traffic.pl to monitor /dev/ath0 instead of /dev/eth0.
Likewise you have to modify /var/www/rrdtool_daily.html and change eth0 to ath0. Do this for weekly, monthly, and yearly.
I changed hda to sda to monitor my actual HD as well.
Now the web display for rrdtool is correct for my system, very easy to change.

I think you mean: /usr/local/bin/rrd_*.pl

OK, I got my RRDtool graphs updating by using the suggestion in the "Don't Panic" thread. However, my eth0 chart isn't updating. I actually do have an eth0 (I even double checked my ifconfig just to make sure it wasn't something strange). I am using an HDHomeRun device as my HD tuner, so I know that I should be having some network traffic, but it is not showing up on my charts.
Where should I begin my search to get this configured correctly for my system?
Thanks,

A search of the forum on rrd_traffic should do it.

Thanks, I had been searching for rrdtool, which doesn't exist anywhere in that thread.

I did a little modding also. I have many hard drives and I wanted it to report the temp for all the hard drives so I modded the script to get them all.
Code: #!/usr/bin/perl # # copyright Martin Pot 2003 # http://martybugs.net/linux/hddtemp.cgi # # rrd_hddtemp.pl
use RRDs;
# define location of rrdtool databases my $rrd = '/var/lib/rrd'; # define location of images my $img = '/var/www/rrdtool';
#Define Drives $hd1 = 'hda'; $hd2 = 'hdb'; $hd3 = 'sda'; $hd4 = 'sdb'; #define drive descriptions $hd1des = 'Maxtor 120G'; $hd2des = 'Maxtor 160G'; $hd3des = 'WD 500G '; $hd4des = 'Maxtor 250G';
# process data for each specified HDD (add/delete as required) &ProcessHDD($hd1, $hd1des); &ProcessHDD($hd2, $hd2des); &ProcessHDD($hd3, $hd3des); &ProcessHDD($hd4, $hd4des);
sub ProcessHDD { # process HDD # inputs: $_[0]: hdd (ie, hda, etc) # $_[1]: hdd description
# get hdd temp for master drive on secondary IDE channel my $temp=`/usr/sbin/hddtemp -n /dev/$_[0]`; # remove eol chars and white space $temp =~ s/[\n ]//g;
print "$_[1] (/dev/$_[0]) temp: $temp degrees C\n";
# if rrdtool database doesn't exist, create it if (! -e "$rrd/$_[0].rrd") { print "creating rrd database for /dev/$_[0]...\n"; RRDs::create "$rrd/$_[0].rrd", "-s 300", "DS:temp:GAUGE:600:0:100", "RRA:AVERAGE:0.5:1:576", "RRA:AVERAGE:0.5:6:672", "RRA:AVERAGE:0.5:24:732", "RRA:AVERAGE:0.5:144:1460"; }
# insert value into rrd RRDs::update "$rrd/$_[0].rrd", "-t", "temp", "N:$temp";
} &CreateGraph("", "day"); &CreateGraph("", "week"); &CreateGraph("", "month"); &CreateGraph("", "year");
sub CreateGraph { # creates graph # inputs: $_[0]: hdd name (ie, hda, etc) # $_[1]: interval (ie, day, week, month, year) # $_[2]: hdd description
RRDs::graph "$img/hddtemp-$_[1].png", "--lazy", "-s -1$_[1]", "-t hdd temperature :: Hard Disk Drives", "-h", "80", "-w", "600", "-a", "PNG", "-v degrees C", "DEF:$hd1=$rrd/$hd1.rrd:temp:AVERAGE", "DEF:$hd2=$rrd/$hd2.rrd:temp:AVERAGE", "DEF:$hd3=$rrd/$hd3.rrd:temp:AVERAGE", "DEF:$hd4=$rrd/$hd4.rrd:temp:AVERAGE", "LINE2:$hd1#0000FF:$hd1des", "GPRINT:$hd1:MIN: Min\\: %2.lf", "GPRINT:$hd1:MAX: Max\\: %2.lf", "GPRINT:$hd1:AVERAGE: Avg\\: %4.1lf", "GPRINT:$hd1:LAST: Current\\: %2.lf degrees C\\n", "LINE2:$hd2#CC00CC:$hd2des", "GPRINT:$hd2:MIN: Min\\: %2.lf", "GPRINT:$hd2:MAX: Max\\: %2.lf", "GPRINT:$hd2:AVERAGE: Avg\\: %4.1lf", "GPRINT:$hd2:LAST: Current\\: %2.lf degrees C\\n", "LINE2:$hd3#339900:$hd3des", "GPRINT:$hd3:MIN: Min\\: %2.lf", "GPRINT:$hd3:MAX: Max\\: %2.lf", "GPRINT:$hd3:AVERAGE: Avg\\: %4.1lf", "GPRINT:$hd3:LAST: Current\\: %2.lf degrees C\\n", "LINE2:$hd4#553388:$hd4des", "GPRINT:$hd4:MIN: Min\\: %2.lf", "GPRINT:$hd4:MAX: Max\\: %2.lf", "GPRINT:$hd4:AVERAGE: Avg\\: %4.1lf", "GPRINT:$hd4:LAST: Current\\: %2.lf degrees C\\n";
if ($ERROR = RRDs::error) { print "$0: unable to generate $_[1] graph: $ERROR\n"; } } To set it up for yourself, just modify Code: #Define Drives $hd1 = 'hda'; $hd2 = 'hdb'; $hd3 = 'sda'; $hd4 = 'sdb'; #define drive descriptions $hd1des = 'Maxtor 120G'; $hd2des = 'Maxtor 160G'; $hd3des = 'WD 500G '; $hd4des = 'Maxtor 250G'; to match your own setup, and if you don't have 4 hard drives you can comment out the lines necessary in Code: # process data for each specified HDD (add/delete as required) &ProcessHDD($hd1, $hd1des); &ProcessHDD($hd2, $hd2des); &ProcessHDD($hd3, $hd3des); &ProcessHDD($hd4, $hd4des); and you will also need to comment out the lines at the bottom that involve the above commented lines eg: Code: "DEF:$hd4=$rrd/$hd4.rrd:temp:AVERAGE", and Code: "LINE2:$hd4#553388:$hd4des", "GPRINT:$hd4:MIN: Min\\: %2.lf", "GPRINT:$hd4:MAX: Max\\: %2.lf", "GPRINT:$hd4:AVERAGE: Avg\\: %4.1lf", "GPRINT:$hd4:LAST: Current\\: %2.lf degrees C\\n"; WARNING: if you do comment out the lines above you will need to move the ; to the last line of the last hard drive you are monitoring You will also need to modify your /var/www/rrdtool_*.html so it picks up the correct graph. replace hda with hddtemp on the line Code: <p align="center" class="style2 style1"><img src="rrdtool/hddtemp-day.png" alt="hddtemp_day" width="693" height="161">

The disk activity and temperature monitoring (and possibly other things) should really loop over multiple devices and process them. This avoids the need for most folks to tweak these things manually. Sadly I've made great strides in forgetting most of the Perl I ever learned, and really don't want to reverse the process for long enough to fix this. Can some helpful perlyte have a go at this?
- rrd_disk.pl Should either sum up the activity from all the drives matching "^[hs]d[a-h]" as listed by "/usr/bin/iostat -d", or draw a stack chart of activity for the various drives.
- rrd_hddtemp.pl should either draw a chart for each drive or plot a different colored line on the same chart for each drive detected via "hddtemp /dev/[hs]d[a-h]". Note that this will require filtering out lines like this:
Code: /dev/hdc: _NEC DVD_RW ND-3520A: S.M.A.R.T. not available
(edit 1: Corrected the hddtemp command since the names would be needed.)

Is it possible to add the /var/lib/rrd directory to the backup and restore scripts?

Thanks Gnarl, the scripts work great. I was waiting for someone to put them together as my perl skills were just a little (very) rusty.

That is what the supplemental /myth/backup/backup.list and /myth/backup/restore.list files are for. See the "Taking advantage of the enhanced backup and restore scripts" posting for more details.
You probably want to add:
Code: ./var/lib/rrd ./var/www/rrdtool_daily.html ./var/www/rrdtool_monthly.html ./var/www/rrdtool_weekly.html ./var/www/rrdtool_yearly.html ./usr/local/bin/rrd_cpu.pl ./usr/local/bin/rrd_disk.pl ./usr/local/bin/rrd_hddtemp.pl ./usr/local/bin/rrd_mbtemp.pl ./usr/local/bin/rrd_mem.pl ./usr/local/bin/rrd_traffic.pl

OBTW - I changed the data collection bit of my rrd_disk.pl like this to give a simple summary:
Code: my @diskdata = `/usr/bin/iostat -d | awk '/[hs]d[a-h]/ {rd+=\$5;wr+=\$6;} END {print rd,wr}'`; my $temp = $diskdata[0]; chomp($temp);
my @tempa = split(/\s+/, $temp);
$readsect= $tempa[0]; $writesect= $tempa[1];
print "Sectors read:$readsect Sectors written:$writesect\n";

This seems like the appropriate thread for this...
I'm struggling with adding additional hard drive temps to the included perl script rrd_HDtemp.pl in R5F1. I used Gnarl's script above with R5E50, but I wanted to try to get it to work with the script in R5F1 and use only one rrd db (i.e. all data stored in HDtemp.rrd). Gnarl's requires a seperate db for each HDD. I have two HDD, both are SATA, so sda and sdb. I've been working on this for a few days and can't seem to make headway. Can anyone offer assistance?

Ok, I figured it out... In case anyone needs to add a second hard drive for temperature monitoring, here's my script and associated section of the config file:
