Nach dem Servercrash am Wochenende und der anschliessenden Installationsorgie habe ich mir überlegt wie man auf dem Desktop einfach seine Serverstatus anzeigen kann.

Da ich sowieso schon Conky auf meinem Desktop einsetze, überlegte ich mir wie das am einfachsten zu Handhaben ist.

Ablauf ist wie folgt:

Per Ping wird überprüft ob der Server online ist. Je nach Status wird eine Datei mit der IP/Hostname angelegt und das ganze von Conky dann optisch dargestellt. Dazu kann man die History derServerstatus im Verzeichnis "/.status/history" je IP/Hostname verfolgen.

Meine .conkyrc:

Dazu passend müssen im Verzeichnis ".conky" de beiden Dateien "publicip.sh" und "ping.sh" angelegt werden

publicip.sh

 #!/bin/bash
# eigene öffentliche ip anzeigen

wget http://checkip.dyndns.org/ -q -O - |
grep -Eo '\<[[:digit:]]{1,3}(\.[[:digit:]]{1,3}){3}\>'

ping.sh

 #!/bin/bash
#CHDATE=`date +%F-%R`
echo $CHDATE;
#if  [["$#" != "3"]] ; then echo "Usage: silentping IP onsign offsign"; fi
# Get the status
STATUS="$(ping $1 -c 1 -w 2 | grep packets | sed "s/^.*tted, //;s/1/$2/;s/0/$3/;s/ re.*$//")"
# Create the directory
if [ ! -d ~/.conky/status ]; then mkdir ~/.conky/status; fi
if [ ! -d ~/.conky/status/history ]; then mkdir ~/.conky/status/history; fi
if [ ! -d ~/.conky/status/history/$1 ]; then mkdir ~/.conky/status/history/$1; fi
# Remove the old status
if [ "$STATUS" == "$2" ]; then
  if [ -f ~/.conky/status/$1.$3 ]; then mv ~/.conky/status/$1.$3 ~/.conky/status/history/$1/$1.$2.`date +%F-%R`; fi
else
  if [ -f ~/.conky/status/$1.$2 ]; then mv ~/.conky/status/$1.$2 ~/.conky/status/history/$1/$1.$3.`date +%F-%R`; fi
fi
# Create the new status file
if [ ! -f ~/.conky/status/$1.$STATUS ]; then touch ~/.conky/status/$1.$STATUS; fi
