import csv file with data to mysql

I'm trying to import csv file to MYSQL, and I have the following schema.

CREATE TABLE `monitor` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`time` time DEFAULT NULL,
`domain_name` text,
`cpu_ns` int(11) DEFAULT NULL,
`cpu_percentage` int(11) DEFAULT NULL,
`mem_bytes` int(11) DEFAULT NULL,
`mem_percentage` int(11) DEFAULT NULL,
`block_rdby` int(11) DEFAULT NULL,
`block_wrby` int(11) DEFAULT NULL,
`net_rxby` int(11) DEFAULT NULL,
`net_wrby` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1

I'm having issues importing a file with data presented as follows. 

16:48:27,2,s-1-VM,220000000.,0.448204684384,262144,0,0,0,60,0
16:48:30,2,s-1-VM,260000000.,0.528932926209,262144,0,0,16384,300,0
16:48:33,2,s-1-VM,300000000.,0.609786677944,262144,0,0,0,180,0
16:48:37,2,s-1-VM,290000000.,0.59000206364,262144,0,0,16384,120,0

16:48:49,2,s-1-VM,200000000.,0.407008216196,262144,0,0,0,300,0
16:48:52,2,s-1-VM,250000000.,0.508946559213,262144,0,0,0,240,0
16:48:55,2,s-1-VM,240000000.,0.488674160215,262144,0,0,0,120,0

How can import this to my database?

I have tried the following and I get lots of warnings.

LOAD DATA LOCAL INFILE '/tmp/domain2.csv' INTO TABLE vtop  FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n';

your help is highly appreciated.

Thank you

MySQL isn't an AI and can't figure out that 16:48:27 should go into the the time field - it'll be trying to stuff that into id instead.

You need to explictly map the columns in your CSV file to the fields they should go into in the table: 

LOAD DATA .... (time, domain_name, x, y, z, foo, bar)

If I understand http://dev.mysql.com/doc/refman/5.1/de/load-data.html correctly, you should set ID to null (that makes it auto_increment) via 

"SET id=NULL "

at the end of the statement. Otherwise column counts and column orders have to match perfectly.

But your columns don't match at all (what is the "2" at position 2?). So create a temp-Table with the structure of your CSV and then assign via insert into ... select the matching columns.
