Zabbix - 04 custom templates, web monitoring

A custom template

1. Create a template

1.1 cloned three

1.2 Direct created a trigger

1.3 Creating Graphics

The template is created, you can create a host again with the direct selection

Modify the template, can all take effect

For example: the modified time 30 days

2. Export Templates

3. Monitoring TCP11 states

Write zabbix profile

[root@web01 /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. Restart zabbix-agent

[root@web01 ~]# systemctl restart zabbix-agent.service 

3.3. Test Monitor items

Use zabbix-get command to test

[root@m01 ~]# yum install zabbix-get.x86_64 -y
[root@m01 ~]# zabbix_get -s 10.0.1.7 -k ESTABLISHED
2
[root@m01 ~]# zabbix_get -s 10.0.1.7 -k LISTEN
12

4. import file template

The host associated template file

6. View the latest data

7. View graphics

Second, the custom template to monitor the state of nginx

1. Turn on the monitor page and access test

[root@web01 ~]# cat /etc/nginx/conf.d/status.conf 
server {
   listen 80;
   server_name localhost;
   location /nginx_status {
       stub_status on;
       access_log off;
   }
}

[root@web01 ~]# curl 127.0.0.1/nginx_status/
Active connections: 1 
server accepts handled requests
 6 6 6 
Reading: 0 Writing: 1 Waiting: 0 

2. Prepare nginx monitor the status of the script

[root@web01 /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. Write zabbix monitoring profile

[root@web01 ~]# cat /etc/zabbix/zabbix_agentd.d/nginx_status.conf
UserParameter=nginx_status[*],/bin/bash /etc/zabbix/zabbix_agentd.d/nginx_monitor.sh $1

[root@web01 ~]# systemctl restart zabbix-agent.service

4. Use Value zabbix_get

[root@m01 ~]# zabbix_get -s 10.0.1.7 -k nginx_status[accepts]
7

5. Template Import

6. Link templates

7. View data

Third, custom templates to monitor the state of php

1. Open the monitoring page

[root@web01 ~]# tail -1 /etc/php-fpm.d/www.conf    
pm.status_path = /php_status

[root@web01 ~]# 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;
   }
}

[root@web01 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@web01 ~]# systemctl restart nginx.service php-fpm.service

2. Access Test

[root@web01 ~]# 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. Prepare access script

[root@web01 ~]# cat /etc/zabbix/zabbix_agentd.d/fpm.sh 
#!/bin/bash

# php-fpm:
#  - anything available via FPM status page

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:

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

[root@web01 ~]# bash /etc/zabbix/zabbix_agentd.d/fpm.sh "total processes" http://127.0.0.1/php_status
5

4. Prepare zabbix profile

[root@web01 ~]# cat /etc/zabbix/zabbix_agentd.d/fpm.conf    
UserParameter=php-fpm[*],/etc/zabbix/zabbix_agentd.d/fpm.sh "$1" "$2"
[root@web01 ~]# systemctl restart zabbix-agent.service

4. Use Value zabbix_get

[root@m01 ~]# zabbix_get -s 10.0.1.7 -k php-fpm["total processes",http://127.0.0.1/php_status]
5

5. Template Import

You need to modify the template in the macro configuration after importing

Four, WEB monitoring

Demand, monitor page status code

Creating Triggers

When stopped service

Start Service

V. fault record summary

Fault 1

Symptom:
Tips zabbix-server is not running

img

Error log:

 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)

Cause of the malfunction:
zabbix-Server configuration file with the configuration database password
Troubleshooting:
add the correct account password information database

[root@m01 ~]# grep "^DB" /etc/zabbix/zabbix_server.conf     
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix

Fault 2

Symptom: micro-channel alarm failed
error log:

[root@m01 ~]# 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

Cause of the problem:
the lack of module requests

Problem Solving:
install the missing dependencies

[root@m01 ~]# yum install python-pip
[root@m01 ~]# pip install --upgrade pip
[root@m01 ~]# pip install requests

Fault 3

: Symptom
WARNING When using zabbix_get command key test command server side

[root@m01 ~]# 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
