windows diskfree - without agents

[michu]

hey all

i needed to check, if my windows server running out of disk-space but without any agents... so i created some scripts to check it.. not the most elegant solution but perhaps someone find it usefull:

(you need to install this scrips on the zabbix machine)

-[hdvoll.sh]------------------------------
#!/bin/bash

##
## 25.05.05 - michael vogt - v 1.0
##
## gibt benutzen plattenplatz in prozent zurueck
## parameter 1 ist hostname, parameter 2 ist disk id
##
## zb "./df 192.168.22.42 1" gibt die diskauslastung der disk 1 zurueck
##

host=$1
disk=$2

mulfix=1000000000 #because bash dosnt know floats... (or i dont know how to use it..)

SUSED=$(snmpget -P e -O q $host public host.hrStorage.hrStorageTable.hrStorageEntry.hrSto rageUsed.$disk | cut -f2 -d" ")
STOTAL=$(snmpget -P e -O q $host public host.hrStorage.hrStorageTable.hrStorageEntry.hrSto rageSize.$disk | cut -f2 -d" ")

#echo "tot: $STOTAL"
#echo "use: $SUSED"

if [ "$STOTAL" = "0" ]
then printf 'ERROR\n'
else
if [ "$STOTAL" = "" ]
then printf 'ERROR\n'
exit 1;
fi
divres=$((100 * $mulfix / $STOTAL))
resultm=$(($divres * $SUSED))
resultUnrounded=$(($resultm / ($mulfix/10))) # a primitive rounding algo...
resultUnroundedA=$(($resultUnrounded + 5))
result=$(($resultUnroundedA /10))
echo $result
fi
--------------------------------------------------------------

-[cronjob.sh]-------------------------------------------------------------
#use the tmp file, else its too fast and we get strange results
#SERVER01 F:
/opt/zabbix/hd_voll server01 4 > /opt/zabbix/disk/tmp
mv /opt/zabbix/disk/tmp /opt/zabbix/disk/server014
#SERVER01 C:
/opt/zabbix/hd_voll server01 2 > /opt/zabbix/disk/tmp
mv /opt/zabbix/disk/tmp /opt/zabbix/disk/server012
--------------------------------------------------------------

add the following lines to zabbix_agentd.conf and restart zabbix_agentd
UserParameter=DiskFree[SERVER01f],/bin/cat /opt/zabbix/disk/server014
UserParameter=DiskFree[SERVER01c],/bin/cat /opt/zabbix/disk/server012

now make sure, that the cronjob.sh script is called once per hour with cron.

now in zabbix use the localhost to add these 2 hosts (image1)

detail host view: image2.png

check image3.png for a rela life example..

From reading the script, it appears you are using SNMP to get the information therefore a SNMP Daemon / service needs to be running on the Microsoft server.

..

yes exactly... but i think in a company, the microsoft snmp service is easier to install than a 3rd party service...
