1.监控原理
将APC源码包中的apc.php放到/usr/local/bin/ 目录下
添加nginx子配置文件php-apc_status.conf
server { listen 80; server_name 127.0.0.1; access_log off; client_max_body_size 5m; autoindex off; location / { root /usr/local/zabbix/bin/; index index.php; autoindex off; } location ~ \.php$ { root /usr/local/zabbix/bin/; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name; include fastcgi_params; } }通过links这个命令可以在命令行下方为HTML页面
links 127.0.0.1/apc.php -dump 2>/dev/null
如果没有这个命令可以用过yum -y install links 安装
2.编写PHP-APC状态信息获取脚本
php-apc_status.sh
#!/bin/bash #This script is used to get php apc cache data from apc.php page #you need put nginx sub-config file php-apc_status.conf under conf/conf.d/ directory apc_metric=$1 apc_status_url="http://127.0.0.1/apc.php" apc_status_file=/tmp/php-apc_status.txt /usr/bin/links $apc_status_url -dump 2>/dev/null > $apc_status_file #echo $apc_status #we need to convert GBytes,Mbytes,KBytes to Bytes #echo "308.345 * 1024 * 1024 * 1024"|bc|cut -f1 -d. #331082922721 convert_size() { value=$1 unit=$2 echo $value | grep -E '^[0-9.]+$' 2>&1 > /dev/null if [ $? -ne 0 ]; then echo "$value is not number" exit 1 fi case $unit in Bytes) echo "$value" ;; KBytes) echo "$value * 1024" | bc | cut -f1 -d. ;; MBytes) echo "$value * 1024 * 1024" | bc | cut -f1 -d. ;; GBytes) echo "$value * 1024 * 1024 * 1024" | bc | cut -f1 -d. ;; esac } #get apc metric data case $apc_metric in version) cat $apc_status_file|grep "APC Version"|awk '{print $3}' ;; cached_files_count) cat $apc_status_file|grep "Cached Files"|head -1|awk '{print $3}' ;; cached_files_size) convert_size $(cat $apc_status_file|grep "Cached Files"|awk '{print $4 " " $5}'|sed -e 's/(//' -e 's/)//') ;; hits) cat $apc_status_file|grep "Hits"|head -1|awk '{print $2}' ;; phits) cat $apc_status_file|grep "Free"|head -1|awk '{print $7}'|sed -e 's/(//' -e s'/)//' -e 's/%//' ;; misses) cat $apc_status_file|grep "Misses"|head -1|awk '{print $2}' ;; request_rate) cat $apc_status_file|grep "Request Rate"|head -1|awk '{print $5}' ;; hit_rate) cat $apc_status_file|grep "Hit Rate"|head -1|awk '{print $3}' ;; miss_rate) cat $apc_status_file|grep "Miss Rate"|head -1| awk '{print $3}' ;; insert_rate) cat $apc_status_file|grep "Insert Rate"|head -1| awk '{print $3}' ;; cache_full_count) cat $apc_status_file|grep "Cache full count"|head -1|awk '{print $4}' ;; shm_size) #apc.shm_size can be 400M or 2G , convert M or G to Bytes shm=$(cat $apc_status_file|grep "apc.shm_size"|head -1| awk '{print $2}') if [ $(echo "$shm"|grep 'M$') ];then size=$(echo $shm|sed 's/M//') echo "$size * 1024 * 1024"|bc elif [ $(echo "$shm"|grep 'G$') ];then size=$(echo $shm|sed 's/G//') echo "$size * 1024 * 1024 * 1024"|bc fi ;; mem_free) convert_size $(cat $apc_status_file|grep "Free"|head -1|awk '{print $2 " " $3}') ;; mem_used) convert_size $(cat $apc_status_file|grep "Used"|head -1|awk '{print $2 " " $3}') ;; mem_pused) cat $apc_status_file|grep "Used"|head -1|awk '{print $4}'|sed -e 's/(//' -e 's/)//' -e 's/%//' ;; fragmentation) cat $apc_status_file|grep "Fragmentation:"|head -1|awk '{print $2}'|sed -e 's/%//' ;; *) echo "please input the right parameter" ;; esac3.添加zabbix 子配置文件php-apc_status_zabbix.conf
