核心数据库10.100.0.20和21表空间已经修改完成，可以正常监控使用率和大小，并邮件告警通知。
修改Oracle数据库表空间监控
创建表空间信息收集脚本：
vim /home/oracle/scripts/check_tablespace.sh
脚本内容如下：
#!/bin/bash
# tablespace usagep check
source ~/.bash_profile
function check {
sqlplus -S "/ as sysdba" << EOF
set numwidth 20
set linesize 200
set pagesize 200
spool /tmp/ora_tablespace.txt
select aa.tablespace_name,
round(bb.maxs, 2) "MAX(G)",
round(aa.usd, 2) "USED(G)",
round((bb.maxs - aa.usd) , 2) "FREE(G)",
round(aa.usd / bb.maxs * 100, 2) "USED%"
from (Select b.Tablespace_Name, (b.Bytes - Nvl(a.Bytes, 0)) "USD"
From (select tablespace_name, sum(bytes) bytes
from Dba_Free_Space
group by tablespace_name) a,
(select tablespace_name, sum(bytes) bytes
from Dba_Data_Files
group by tablespace_name) b
Where b.tablespace_name = a.tablespace_name(+)
-- and b.tablespace_name='MAXIMO_DATA'
) aa,
(select tablespace_name,
sum(case
when maxbytes = 0 then
user_bytes
else
maxbytes
end) "MAXS"
from dba_data_files
-- where tablespace_name='MAXIMO_DATA'
group by tablespace_name
order by tablespace_name) bb
where aa.tablespace_name = bb.tablespace_name and aa.tablespace_name not like '%UNDO%'
order by 5 desc, 1;
spool off
set linesize 100
set pagesize 100
spool /tmp/ora_autex.txt
select tablespace_name,autoextensible from dba_data_files;
spool off
quit
EOF
};check &>/dev/null
赋予执行权限
chmod +x /home/oracle/scripts/check_tablespace.sh
配置计划任务(oracle用户)
*/5 * * * * /home/oracle/scripts/check_tablespace.sh
手动执行脚本并查看结果
表空间脚本执行结果
自动发现脚本内容如下：
# cat discovery_oracle_tablespace.sh
#!/bin/bash
#zabbix discovery oracle tablespace
table_spaces=(`cat /tmp/ora_tablespace.txt | sed -e "1,3d" -e "/^$/d" -e "/selected/d" | awk '{print $1}'`)
length=${#table_spaces[@]}
printf "{\n"
printf '\t'"\"data\":["
for ((i=0;i<$length;i++))
do
printf "\n\t\t{"
printf "\"{#TABLESPACE_NAME}\":\"${table_spaces[$i]}\"}"
if [ $i -lt $[$length-1] ];then
printf ","
fi
done
printf "\n\t]\n"
printf "}\n"
执行结果
# ./discovery_oracle_tablespace.sh
{
"data":[
{"{#TABLESPACE_NAME}":"EMA"},
{"{#TABLESPACE_NAME}":"SYSAUX"},
{"{#TABLESPACE_NAME}":"MHWEB"},
{"{#TABLESPACE_NAME}":"SYSTEM"},
{"{#TABLESPACE_NAME}":"OGG"},
{"{#TABLESPACE_NAME}":"USERS"},
{"{#TABLESPACE_NAME}":"QDPTTBS"},
{"{#TABLESPACE_NAME}":"UYUN"},
{"{#TABLESPACE_NAME}":"LINKSCAPEH5DB"},
{"{#TABLESPACE_NAME}":"WX_HUANGHE_TBS"}
]
}
监控项脚本内容如下：
# cat tablespace_check.sh
#!/bin/bash
# oracle tablespace check
CEHCK_TYPE=$1
TABLESPACE_NAME=$2
function usagepre {
grep "\b$TABLESPACE_NAME\b" /tmp/ora_tablespace.txt | awk '{printf "%.f\n",$5}'
# grep "\b$TABLESPACE_NAME\b" /tmp/ora_tablespace.txt | awk '{printf "%.f\n",$3/$2*100}'
}
function available {
grep "\b$TABLESPACE_NAME\b" /tmp/ora_tablespace.txt | awk '{printf $4}'
# grep "\b$TABLESPACE_NAME\b" /tmp/ora_tablespace.txt | awk '{printf ($2-$3)*1024*1024}'
}
function check {
if grep "\b$TABLESPACE_NAME\b" /tmp/ora_autex.txt | awk '{print $2}' | uniq | grep "YES" &>/dev/null;then
echo 1
else
echo 0
fi
}
case $CEHCK_TYPE in
pre)
usagepre ;;
fre)
available ;;
check)
check ;;
*)
echo -e "Usage: $0 [pre|fre|check] [TABLESPACE_NAME]"
esac
Agent参数配置：
# cat /etc/zabbix/zabbix_agentd.d/oracle_tablespace.conf
UserParameter=discovery.oracle.tablespace,/etc/zabbix/scripts/discovery_oracle_tablespace.sh
UserParameter=tablespace.check[*],/etc/zabbix/scripts/tablespace_check.sh $1 $2
重启zabbix-agent
主机添加模板
添加自动发现模板
等待一会后查看监控结果：
表空间监控的数据
监控指标图形展示：
这个的告警我就不去模拟了，因为都是生产环境的，下图为4月份的TEMP表空间告警邮件截图：
