zabbix3.2學習筆記（六）：自定義監控nginx+php-fpm status

zabbix自帶了一些模版，可根據須要修改對應監控項的閾值；但是像nginx/ph-fpm/redis/mysql等一些應用還須要咱們自定義監控項、用腳本在客戶端取值。下面簡單監控nginx和php-fpm的狀態：兩者自己自帶status參數，只需開啓便可。

1，開啓status

vi /etc/php-fpm.conf 尾部添加一行
pm.status_path = /php-fpm_status

cd /etc/nginc/conf.d/
vi nginxphp_status.conf
server {

listen 40080;
allow 127.0.0.1;
deny all;
access_log off;
location /php-fpm_status {
     fastcgi_pass 127.0.0.1:9000;
      include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
}

location /nginx_status {
      stub_status on;
}
}

service php-fpm restart
service nginx restart

curl -s http://127.0.0.1:40080/nginx_status
Active connections: 1
server accepts handled requests
6 6 6
Reading: 0 Writing: 1 Waiting: 0

nginx status詳解
active connections – 活躍的鏈接數
server accepts handled requests — 總共處理了6個鏈接 , 成功建立6次握手, 總共處理了6個請求
reading — 讀取客戶端的鏈接數
writing — 響應數據到客戶端的數量
waiting — 開啓 keep-alive 的狀況下,這個值等於 active – (reading+writing), 意思就是 Nginx 已經處理完正在等候下一次請求指令的駐留鏈接。因此,在訪問效率高,請求很快被處理完畢的狀況下,Waiting數比較可能是正常的.若是reading +writing數較多,則說明併發訪問量很是大,正在處理過程當中。

curl -s http://127.0.0.1:40080/php-fpm_status
pool: www
process manager: dynamic
start time: 17/Aug/2017:17:09:32 +0800
start since: 64
accepted conn: 2
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

php-fpm status詳解
pool – fpm池子名稱，大多數爲www 
process manager – 進程管理方式,值：static, dynamic or ondemand. dynamic 
start time – 啓動日期,若是reload了php-fpm，時間會更新 
start since – 運行時長 
accepted conn – 當前池子接受的請求數 
listen queue – 請求等待隊列，若是這個值不爲0，那麼要增長FPM的進程數量 
max listen queue – 請求等待隊列最高的數量 
listen queue len – socket等待隊列長度 
idle processes – 空閒進程數量 
active processes – 活躍進程數量 
total processes – 總進程數量 
max active processes – 最大的活躍進程數量（FPM啓動開始算） 
max children reached - 大道進程最大數量限制的次數，若是這個數量不爲0，那說明你的最大進程數量大小了，需改大一點。 
php-fpm狀態頁能夠經過帶參數實現個性化，能夠帶參數json、xml、html而且前面三個參數能夠分別和full作一個組合。
json格式：http://127.0.0.1:40080/php-status?json
xml格式： http://127.0.0.1:40080/php-status?xml
html 格式： http://127.0.0.1:40080/php-status?html 
full格式： http://127.0.0.1:40080/php-status?ful

2，在zabbix agent端新建shell腳原本取值
cd /etc/zabbix/zabbix_agentd.d
vi php-fpm_status.sh

#!/bin/bash

idle(){
        wget --quiet -O - http://127.0.0.1:40080/php-fpm_status?auto |grep "idle processes" |awk '{print$3}'
}

total(){
        wget --quiet -O - http://127.0.0.1:40080/php-fpm_status?auto |grep "total processes" |awk '{print$3}'
}

active(){
        wget --quiet -O - http://127.0.0.1:40080/php-fpm_status?auto |grep "active" |awk '{print$3}'|grep -v "process"
}

mactive(){

        wget --quiet -O - http://127.0.0.1:40080/php-fpm_status?auto |grep "max active processes:" |awk '{print$4}'
}

listenqueuelen(){
        wget --quiet -O - http://127.0.0.1:40080/php-fpm_status?auto |grep "listen queue len" |awk '{print$4}'
}

listenqueue(){
        wget --quiet -O - http://127.0.0.1:40080/php-fpm_status?auto |grep "listen queue:"|grep -vE "len|max"|awk '{print$3}'
}

since(){
        wget --quiet -O - http://127.0.0.1:40080/php-fpm_status?auto |grep "start since: " |awk '{print$3}'
}

conn(){
        wget --quiet -O - http://127.0.0.1:40080/php-fpm_status?auto |grep "accepted conn" |awk '{print$3}'
}
$1

vi nginx_status.sh

#!/bin/bash

Active(){
        wget --quiet -O - http://localhost:40080/nginx_status?auto |awk 'NR==1 {print$3}'
}
Reading(){
        wget --quiet -O - http://localhost:40080/nginx_status?auto |awk 'NR==4 {print$2}'
}
Writing(){
        wget --quiet -O - http://localhost:40080/nginx_status?auto |awk 'NR==4 {print$4}'
}
Waiting(){
        wget --quiet -O - http://localhost:40080/nginx_status?auto |awk 'NR==4 {print$6}'
}
$1
3，修改/etc/zabbix/zabbix_agentd.conf添加一下內容
UnsafeUserParameters=1 

UserParameter=idle.processe,/etc/zabbix/zabbix_agentd.d/php-fpm_status.sh idle
UserParameter=total.processes,/etc/zabbix/zabbix_agentd.d/php-fpm_status.sh total
UserParameter=active.processes,/etc/zabbix/zabbix_agentd.d/php-fpm_status.sh active
UserParameter=max.active.processes,/etc/zabbix/zabbix_agentd.d/php-fpm_status.sh mactive
UserParameter=listen.queue.len,/etc/zabbix/zabbix_agentd.d/php-fpm_status.sh listenqueuelen
UserParameter=listen.queue,/etc/zabbix/zabbix_agentd.d/php-fpm_status.sh listenqueue
UserParameter=start.since,/etc/zabbix/zabbix_agentd.d/php-fpm_status.sh since
UserParameter=accepted.conn,/etc/zabbix/zabbix_agentd.d/php-fpm_status.sh conn

UserParameter=Active,/etc/zabbix/zabbix_agentd.d/nginx_status.sh Active
UserParameter=Reading,/etc/zabbix/zabbix_agentd.d/nginx_status.sh Reading
UserParameter=Writing,/etc/zabbix/zabbix_agentd.d/nginx_status.sh Writing
UserParameter=Waiting,/etc/zabbix/zabbix_agentd.d/nginx_status.sh Waiting

service zabbix-agent restart

4，在zabbix web端導入如下模版
http://pan.baidu.com/s/1bp3wJYf

將主機關聯以上模版，隨後在最新數據裏查看是否收集到監控值

github上搜索zabbix會看到不少開源的監控模版，挑你須要的試試吧
