/bin/echo "$Date,$Se,$Cp,$Me" > /log/dbload.txt

/bin/cat /log/dbload.txt | tr -s ‘[:blank:]‘ > /log/dbload2.csv

/usr/bin/mysql -h 10.0.0.2 -u icinga2 -p‘xxxxxxx‘ --local-infile=1 dbload -e "LOAD DATA LOCAL INFILE ‘/log/dbload2.csv‘ INTO TABLE loadavg FIELDS TERMINATED BY ‘,‘"

:wq

mysql部分：

create database dbload default character set utf8;
create table loadvag(time datetime,server char(50),cpu float,mem float);
grant all on dbload.* to icinga2@‘10.%‘ identified by ‘xxxxx‘;
flush privileges;
exit

grafana语句：

select UNIX_TIMESTAMP(Time) as time, cpu as "db2" from loadavg where server="db2";

通过shell抓取mysql应用的CPU、内存负载
