一、自定义模版
1.创建模版
1.1克隆出三台
1.2直接创建好触发器
1.3创建图形
模版创建好,再次创建主机就可直接选择用
修改模版,可全部生效
例如:把时间修改成30天
2.导出模版
3.监控TCP11种状态
编写zabbix配置文件
[[email protected] /etc/zabbix/zabbix_agentd.d]# cat zbx_tcp.conf
UserParameter=ESTABLISHED,netstat -ant|grep -c 'ESTABLISHED'
UserParameter=SYN_SENT,netstat -ant|grep -c 'SYN_SENT'
UserParameter=SYN_RECV,netstat -ant|grep -c 'SYN_RECV'
UserParameter=FIN_WAIT1,netstat -ant|grep -c 'FIN_WAIT1'
UserParameter=FIN_WAIT2,netstat -ant|grep -c 'FIN_WAIT2'
UserParameter=TIME_WAIT,netstat -ant|grep -c 'TIME_WAIT'
UserParameter=CLOSE,netstat -ant|grep -c 'CLOSE'
UserParameter=CLOSE_WAIT,netstat -ant|grep -c 'CLOSE_WAIT'
UserParameter=LAST_ACK,netstat -ant|grep -c 'LAST_ACK'
UserParameter=LISTEN,netstat -ant|grep -c 'LISTEN'
UserParameter=CLOSING,netstat -ant|grep -c 'CLOSING'
3.2.重启zabbix-agent
[[email protected] ~]# systemctl restart zabbix-agent.service
3.3.测试监控项
使用zabbix-get命令测试
[[email protected] ~]# yum install zabbix-get.x86_64 -y
[[email protected] ~]# zabbix_get -s 10.0.1.7 -k ESTABLISHED
2
[[email protected] ~]# zabbix_get -s 10.0.1.7 -k LISTEN
12
4.导入模版文件
5.主机关联模版文件
6.查看最新数据
7.查看图形
二、自定义模版监控nginx状态
1.开启监控页面并访问测试
[[email protected] ~]# cat /etc/nginx/conf.d/status.conf
server {
listen 80;
server_name localhost;
location /nginx_status {
stub_status on;
access_log off;
}
}
[[email protected] ~]# curl 127.0.0.1/nginx_status/
Active connections: 1
server accepts handled requests
6 6 6
Reading: 0 Writing: 1 Waiting: 0
2.准备nginx监控状态脚本
[[email protected] /etc/zabbix/zabbix_agentd.d]# cat nginx_monitor.sh
#!/bin/bash
NGINX_COMMAND=$1
CACHEFILE="/tmp/nginx_status.txt"
CMD="/usr/bin/curl http://127.0.0.1/nginx_status/"
if [ ! -f $CACHEFILE ];then
$CMD >$CACHEFILE 2>/dev/null
fi
# Check and run the script
TIMEFLM=`stat -c %Y $CACHEFILE`
TIMENOW=`date +%s`
if [ `expr $TIMENOW - $TIMEFLM` -gt 60 ]; then
rm -f $CACHEFILE
fi
if [ ! -f $CACHEFILE ];then
$CMD >$CACHEFILE 2>/dev/null
fi
nginx_active(){
grep 'Active' $CACHEFILE| awk '{print $NF}'
exit 0;
}
nginx_reading(){
grep 'Reading' $CACHEFILE| awk '{print $2}'
exit 0;
}
nginx_writing(){
grep 'Writing' $CACHEFILE | awk '{print $4}'
exit 0;
}
nginx_waiting(){
grep 'Waiting' $CACHEFILE| awk '{print $6}'
exit 0;
}
nginx_accepts(){
awk NR==3 $CACHEFILE| awk '{print $1}'
exit 0;
}
nginx_handled(){
awk NR==3 $CACHEFILE| awk '{print $2}'
exit 0;
}
nginx_requests(){
awk NR==3 $CACHEFILE| awk '{print $3}'
exit 0;
}
case $NGINX_COMMAND in
active)
nginx_active;
;;
reading)
nginx_reading;
;;
writing)
nginx_writing;
;;
waiting)
nginx_waiting;
;;
accepts)
nginx_accepts;
;;
handled)
nginx_handled;
;;
requests)
nginx_requests;
;;
*)
echo 'Invalid credentials';
exit 2;
esac
3.编写zabbix监控配置文件
[[email protected] ~]# cat /etc/zabbix/zabbix_agentd.d/nginx_status.conf
UserParameter=nginx_status[*],/bin/bash /etc/zabbix/zabbix_agentd.d/nginx_monitor.sh $1
[[email protected] ~]# systemctl restart zabbix-agent.service
4.使用zabbix_get取值
[[email protected] ~]# zabbix_get -s 10.0.1.7 -k nginx_status[accepts]
7
5.导入模版
6.链接模版
7.查看数据
三、自定义模版监控php状态
1.开启监控页面
[[email protected] ~]# tail -1 /etc/php-fpm.d/www.conf
pm.status_path = /php_status
[[email protected] ~]# cat /etc/nginx/conf.d/status.conf
server {
listen 80;
server_name localhost;
location /nginx_status {
stub_status on;
access_log off;
}
location /php_status {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME html$fastcgi_script_name;
include fastcgi_params;
}
}
[[email protected] ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[[email protected] ~]# systemctl restart nginx.service php-fpm.service
2.访问测试
[[email protected] ~]# curl 127.0.0.1/php_status
pool: www
process manager: dynamic
start time: 08/Aug/2019:22:31:27 +0800
start since: 37
accepted conn: 1
listen queue: 0
max listen queue: 0
listen queue len: 128
idle processes: 4
active processes: 1
total processes: 5
max active processes: 1
max children reached: 0
slow requests: 0
3.准备访问脚本
[[email protected] ~]# cat /etc/zabbix/zabbix_agentd.d/fpm.sh
#!/bin/bash
##################################
# Zabbix monitoring script
#
# php-fpm:
# - anything available via FPM status page

# Zabbix requested parameter
ZBX_REQ_DATA="$1"
ZBX_REQ_DATA_URL="$2"
# Nginx defaults
NGINX_STATUS_DEFAULT_URL="http://localhost/fpm/status"
WGET_BIN="/usr/bin/wget"
#
# Error handling:

#
ERROR_NO_ACCESS_FILE="-0.91"

ERROR_WRONG_PARAM="-0.93"

# Handle host and port if non-default
if [ ! -z "$ZBX_REQ_DATA_URL" ]; then
URL="$ZBX_REQ_DATA_URL"
else
URL="$NGINX_STATUS_DEFAULT_URL"
fi
# save the nginx stats in a variable for future parsing
NGINX_STATS=$($WGET_BIN -q $URL -O - 2>/dev/null)
# error during retrieve
if [ $? -ne 0 -o -z "$NGINX_STATS" ]; then
echo $ERROR_DATA
exit 1
fi
#
# Extract data from nginx stats
#
#RESULT=$(echo "$NGINX_STATS" | awk 'print $0;match($0, "^'"$ZBX_REQ_DATA"':[[:space:]]+(.*)", a) { print a[1] }')
#RESULT=$(echo "$NGINX_STATS" | grep "$ZBX_REQ_DATA" | awk -F : '{print $2}')
RESULT=$(echo "$NGINX_STATS" | awk -F : "{if(\$1==\"$ZBX_REQ_DATA\") print \$2}")
if [ $? -ne 0 -o -z "$RESULT" ]; then
echo $ERROR_WRONG_PARAM
exit 1
fi
echo $RESULT
exit 0
[[email protected] ~]# bash /etc/zabbix/zabbix_agentd.d/fpm.sh "total processes" http://127.0.0.1/php_status
5
4.准备zabbix配置文件
[[email protected] ~]# cat /etc/zabbix/zabbix_agentd.d/fpm.conf
UserParameter=php-fpm[*],/etc/zabbix/zabbix_agentd.d/fpm.sh "$1" "$2"
[[email protected] ~]# systemctl restart zabbix-agent.service
4.使用zabbix_get取值
[[email protected] ~]# zabbix_get -s 10.0.1.7 -k php-fpm["total processes",http://127.0.0.1/php_status]
5
5.导入模版
导入之后需要修改一下模版里的宏配置
四、WEB监控
需求,监控页面状态码
创建触发器
停掉服务时
启动服务
五、故障记录总结
故障1
故障现象:
提示zabbix-server is not running
报错日志:
34983:20190807:202215.171 database is down: reconnecting in 10 seconds
34983:20190807:202225.172 [Z3001] connection to database 'zabbix' failed: [1045] Access denied for user 'zabbix'@'localhost' (using password: NO)
故障原因:
zabbix-server的配置文件里配有配置数据库密码
故障解决:
添加正确的数据库账号密码信息
[[email protected] ~]# grep "^DB" /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
故障2
故障现象:微信报警失败
报错日志:
[[email protected] ~]# tail -f /var/log/zabbix/zabbix_server.log
Problem name: TIME_WAIT过多
Host: web01
Severity: Average
Original problem ID: 51
'": Traceback (most recent call last):
File "/usr/lib/zabbix/alertscripts/weixin.py", line 7, in <module>
import requests
ImportError: No module named requests
问题原因:
缺少模块 requests
问题解决:
安装缺失的依赖包
[[email protected] ~]# yum install python-pip
[[email protected] ~]# pip install --upgrade pip
[[email protected] ~]# pip install requests
故障3
故障现象:
在server端使用zabbix_get命令测试键值命令时提示警告
[[email protected] ~]# zabbix_get -s 10.0.1.7 -k ESTABLISHED
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
2
问题原因:
zabbix_agent是以普通用户zabbix运行的,而普通用户执行netstat -antp时会有警告,网上查找发现只要不是用p参数就可以以普通用户运行
解决方案:
监控脚本里的命令修改为netstat -ant
