RAID STATS / Temperature to MRTG

MRTG wants 4 attributes.
In / Out / Uptime / Hostname.

So I put those 4 things into a file…. n4.$DRIVE
for each drive in the array. Then I’m going to use cron to run this
script (Below) which puts it on a samba share that has the server
that’s running MRTG. Which will also have a cron job that will be
polling that file every 5 minutes. Then running MRTG to grab that
data and store it in it’s log file.

Then It’ll give me out 5 sets of graphs with the temperature displayed
over the last 24 / 48 hours.

I used Drive Temp from SYSCTL
Raspberian Temperature to grab the CPU Temp (Which is an independent device from the drives)
as well as grabbing uptime and hostname…

Getting temperature from the CPU is fairly simple / straightforward as well

Flight Aware

I started running Fligtaware from my home the other day 8/1/20

With a (5 / 7) DBi Antenna

Flightaware Opens in a new Window

and then again on 8/15/20 with another antenna (9 / 10 / 12 DBi)

Flightaware 2
Opens in a new window

The 5/7 is on the roof. The 9/10/12 DBi is in my office.

Going to be putting the larger antenna up on the roof in the near future.

starting my own ddns.

have my own vm with westhost… barilin.com

using cron.

# Updated 2/9/19
2,7,12,17,22,27,32,37,42,47,52,57 * * * * /root/bin/reportipaddress &> /dev/null

I have it running the foloowing every 5 minutes…
pushing the IP Address up to my VM

root@cp1:~/bin# cat reportipaddress
DATE=/usr/bin/date
QUERY=""
QUERY="/usr/bin/curl http://barilin.com/whatipaddressami"
$QUERY
if [ "$QUERY" != "" ]; then
  $ECHO $DATE >> /var/log/reportipaddress.log
fi;
root@cp1:~/bin#

I have it report into my vm and have it query a non exsistant url..
Then I parse the logs every 5 mintues with cron

5,10,15,20,25,30,35,40,45,50,55,59 * * * * ~/bin/5minutes.sh

cron calls a script

[uscopley@sl-508-21 bin]$ cat 5minutes.sh
CAT=/usr/bin/cat
FILE="/home/uscopley/access-logs/barilin.com"
HEADHTML="/home/uscopley/bin/5minutes.head"
TAILHTML="/home/uscopley/bin/5minutes.tail"
GREP=/usr/bin/grep
TAIL="/usr/bin/tail -10"
STRING=whatipaddressami
REPORT="/home/uscopley/www/reportipaddress.html"
#
#
#
$CAT $HEADHTML > $REPORT
$CAT $FILE | $GREP $STRING | $TAIL >> $REPORT
$CAT $TAILHTML >> $REPORT
#
#
#

#cat ~/access-logs/barilin.com | grep whatipaddressami | tail -3 > ~/www/reportipaddress.html

The next part hasn’t been written yet. I’m going to grab that ip address that’s reported
and shove it into dns… With my home A name.

whole lotta pies / Download config on reboot

So, I like to have all my pies download a set of configs at boot. Allows me to make a change
a centeralized location and push it out to everyone (When they reboot)

All pies get this in their /etc/rc.d/rc.local

/home/zero/updates/update.sh
#
/etc/sethostalias.sh > /etc/hostalias
#
/usr/sbin/netdate ntp1 >> /home/netdate/n3.netdate.log
#
sleep 20;
/etc/rc.d/rc.ntpd restart
#

and then of course /etc/fstab has a samba mounted share with the following

//cp1/zero      /home/zero      cifs      user=timc,pass=[password]       0   0

and the /home/zero/updates/update.sh has the following

#
#  Setup some variables
#
CP="/usr/bin/cp"
DIR="/home/zero/updates"
MKDIR="/usr/bin/mkdir"
#
#  Updatre aliases and hosts and profiles from CP1
#
$CP $DIR/sethostalias.sh /etc
$CP $DIR/hosts /etc
$CP $DIR/profile /etc
$CP $DIR/alias /etc
#
#  Make a bin directory for root on host
#
EDIR="/root/bin"
if [ ! -d $EDIR ]; then
  $MKDIR $EDIR
  $CP $DIR/bin/ $EDIR
fi
#
#  Couple files for Serial stuff on PI's
#
$CP $DIR/config.txt /root
$CP $DIR/cmdline.txt /root
$CP $DIR/inittab /root
#
# Couple fixes for snmp / ntp
$CP $DIR/rc.M /etc/rc.d/
$CP $DIR/snmpd.conf /etc/snmp/
$CP $DIR/ntp.conf /etc/

with all the appropiate file goodies. This seems to fluctuate based upon what I’m doing…
