1. 在被監控端創建腳本，此腳本用於獲取表空間及空間使用信息,此腳本由oracle用戶下創建

vim mornitor_tbs.sh

#!/bin/bash
source /home/oracle/.bash_profile
sqlplus -s zabbix/zabbix > /tmp/tablespace.log<<EOF
set linesize 140 pagesize 10000
col "Status" for a10
col "Name" for a25
col "Type" for a10
col "Extent" for a15
SELECT d.status            "Status",
d.tablespace_name   "Name",
d.contents          "Type",
d.extent_management "Extent",
NVL(a.bytes, 0) "Size (M)",
NVL(a.bytes - NVL(f.bytes, 0), 0) "Used (M)",
round(NVL((a.bytes - NVL(f.bytes, 0)) / a.bytes * 100, 0), 2) "Used %"
FROM sys.dba_tablespaces d,
(select tablespace_name, sum(bytes) bytes
from dba_data_files
group by tablespace_name) a,
(select tablespace_name, sum(bytes) bytes
from dba_data_files
group by tablespace_name) a,
(select tablespace_name, sum(bytes) bytes
from dba_free_space
group by tablespace_name) f
WHERE
d.tablespace_name = a.tablespace_name(+)
AND d.tablespace_name = f.tablespace_name(+)
AND d.tablespace_name not in ('SYSAUX', 'SYSTEM')
AND NOT
(d.extent_management like 'LOCAL' AND d.contents like 'TEMPORARY')
UNION ALL
SELECT d.status            "Status",
d.tablespace_name   "Name",
d.contents          "Type",
d.extent_management "Extent",
NVL(a.bytes, 0) "Size (M)",
NVL(t.bytes, 0) "Used (M)",
round(NVL(t.bytes / a.bytes * 100, 0), 2) "Used %"
FROM sys.dba_tablespaces d,
(select tablespace_name, sum(bytes) bytes
from dba_temp_files
group by tablespace_name) a,
(select
tablespace_name, sum(bytes_cached) bytes
from v\$temp_extent_pool
group by tablespace_name) t
WHERE
d.tablespace_name = a.tablespace_name(+)
AND d.tablespace_name = t.tablespace_name(+)
AND
d.extent_management like 'LOCAL'
AND d.contents like 'TEMPORARY'
ORDER BY 7;
EOF
sed -i '$d' /tmp/tablespace.log
sed -i '$d' /tmp/tablespace.log
sed -i 's/,//g' /tmp/tablespace.log

2. 利用腳本(oracle_discovery.sh)對取出數據文件(tablespace.log)進行格式化(因為zabbix自動發現數據類型是jason類型),取出Name那一列，後面配置zabbix自動發現用於自定義宏獲取表空間名稱

vim ora_discovery.sh

#!/bin/bash
TABLESPACE=`cat /tmp/tablespace.log |awk '{print$2}'|awk 'NR>3{print}'`
COUNT=`echo "$TABLESPACE" |wc -l`
INDEX=0
echo '{"data":['
echo "$TABLESPACE" | while read LINE; do
echo -n '{"{#TBSNAME}":"'$LINE'"}'
INDEX=`expr $INDEX + 1`
if [ $INDEX -lt $COUNT ]; then
echo ','
fi
done
echo ']}

3. 利用腳本(oracle_check.sh)獲取數據文件(tablespace.log)後三列

vim oracle_check.sh

#!/bin/bash
EQ_DATA="$2"
ZBX_REQ_DATA_TAB="$1"
SOURCE_DATA=/tmp/tablespace.log
case $2 in
maxmb) grep -Ew "$ZBX_REQ_DATA_TAB" $SOURCE_DATA |awk '{print $5}';;
used) grep -Ew "$ZBX_REQ_DATA_TAB" $SOURCE_DATA |awk '{print $6}';;
autopercent) grep -Ew "$ZBX_REQ_DATA_TAB" $SOURCE_DATA |awk '{print $7}';;
*) echo $ERROR_WRONG_PARAM; exit 1;;
esac
exit 0

4. zabbixagent配置文件添加自定義監控key

vim /etc/zabbix/zabbix_agentd.d/userparameter_oracle.conf

UserParameter=ora.tbs.discovery,/etc/zabbix/zabbix_agentd.d/oracle_discovery.sh

UserParameter=tablespace[*],/etc/zabbix/zabbix_agentd.d/oracle_check.sh $1 $2

5. 配置計劃任務，重啟zabbix_agentd服務

*/10 * * * * /app/scripts/monitor_tbs.sh > /app/scripts/monitor_tbs.log

6. 在zabbix_server端添加discovery模板，之前安裝過orabbix,直接在Template_Oracle下添加discovery rule

Configuration-> Template->Template_Oracle->Discovery Rules-> Create Discovery Rule

創建Item prototypes

Name ：{#TBSNAME} Autopercent

Key ：tablespace[{#TBSNAME},autopercent]
