手头有几台dell服务器,分别是PE2850和PE R710,想把硬件状态监控加入icinga中,但是网上提供的大多是依赖dell openmanager的snmp服务,用起来有些不对劲,自己对snmp所知较少,尤其是那些OID,一大串数字,不知道具体代表什么。
前几天发现openmanager自带的命令omreport可以直接执行,于是写了这个脚本,很简单,分别检查chassis(基础构件,包括主板,电源)和storage(存储)
1. 脚本
vim /usr/local/nagios/libexec/check_dell_omreport
#!/bin/bash
# Program : check_dell_omreport
# Version : 1.0
# Date : Jul 28 2012
# Author : huky -
# Summary : a simple nagios/icinga plugin that checks the status of chassis &
# storage on Dell PowerEdge servers with omreport in Dell Openmanager
# Licence : GPL - summary below, full text at
#这里指定openmanager安装路径,默认是/opt/dell/srvadmin
DELL_SRV_DIR=/opt/dell/srvadmin
PATH=$PATH:$DELL_SRV_DIR/oma/bin:$DELL_SRV_DIR/bin:$DELL_SRV_DIR/sbin
#OMREPORT=`find $DELL_SRV_DIR -name omreport 2> /dev/null`
STOR_CTRL=/tmp/dell.storage.ctr
LOG_FILE=/tmp/dell_omreport.log
STATE_OK=0
STATE_WARNING=1
STATE_CRITICAL=2
STATE_UNKOWN=3
if [ ! -d $DELL_SRV_DIR ]; then
echo "Please install OpenManger and define the PATH after DELL_SRV_DIR" && exit $STATE_UNKOWN
fi
/etc/init.d/dataeng status >> /dev/null
if [ ! $? -eq 0 ]; then
echo "Please start the service dataeng" && exit $STATE_UNKOWN
fi
#check chassis
omreport chassis | grep ^[^Ok] | grep ":" | sed '/COMPONENT/d' > $LOG_FILE
#check storage
omreport storage controller | grep "^ID" | cut -d":" -f2 > $STOR_CTRL
if [ ! -s $STOR_CTRL ]; then
echo "Have you installed the package for storage?" >> $LOG_FILE
fi
for CONTR_ID in `cat $STOR_CTRL`
do
omreport storage controller controller=$CONTR_ID | grep -2
^Status | sed '/--/d' | awk '{if (NR%5==0){print $0} else {printf"%s
",$0}}' | grep -v Ok | tr -s " *" " " >> $LOG_FILE
done
if [ -s $LOG_FILE ]; then
paste -s $LOG_FILE > $LOG_FILE.2
if [ `grep -c "Critical" $LOG_FILE` -eq `grep -c "\-Critical" $LOG_FILE` ]; then
echo `cat $LOG_FILE.2` && exit $STATE_WARNING
else
echo `cat $LOG_FILE.2` && exit $STATE_CRITICAL
fi
else
echo "Machine is Health" && exit $STATUS_OK
fi
2. 安装
2.1 把脚本放在受控端相应位置(默认是这里:/usr/local/nagios/libexec/check_dell_omreport)
2.2 然后在受控端修改nrpe服务的配置文件
vim /usr/local/nagios/etc/nrpe.cfg
增加一行
command[check_omreport]=/usr/local/nagios/libexec/check_dell_omreport
3. 监控
主控端修改相应的监控配置,我是把这几个服务放在一个服务组里面,如下:
define service {
use generic-service
host_name 主机名1,主机名3,主机名3,主机名4,主机名5
service_description Dell_OM
check_command check_nrpe_1arg!check_omreport
}
define servicegroup{
servicegroup_name Hardware_Status
alias 硬件状态
members 主机名1,Dell_OM,主机名2,Dell_OM,主机名3,Dell_OM,主机名4,Dell_OM,主机名5,Dell_OM
}
4. 测试
# /usr/local/icinga/libexec/check_nrpe -H 192.168.10.121 -c check_omreport
Controllers ID : 0 Status : Non-Critical Name : PERC H700 Integrated Slot ID : Embedded Physical Disks ID : 0:0:0 Status : Non-Critical Name : Physical Disk 0:0:0 State : Online ID : 0:0:1 Status : Non-Critical Name : Physical Disk 0:0:1 State : Online ID : 0:0:2 Status : Non-Critical Name : Physical Disk 0:0:2 State : Online
5. 启用
重启服务后,在服务组里面可以看到相关的信息
警告级别的:
阵列卡和磁盘
严重级别的:
