【转】collectd的部署

以版本三为例，因为版本四有太多的改动
wget http://collectd.org/files/collectd-3.11.7.tar.gz
cd /root/collectd-3.11.7
./configure --prefix=/opt/collectd --with-rrdtool=/usr/local/rrdtool/ && make && make install

此段非转载--------------------------------------------------------

我自己机器上

sudo apt install librrd-dev

./configure --enable-rrdtool --with-librrd=/usr/include

-----------------------------------------------------------------------------------
上面是安装server端，因为server端要用到rrdtool来写数据
./configure --prefix=/usr/local/collectd --without-rrdtool && make && make install
这句是安装client端，因为没必要用到rrdtool，所以加了一句--without-rrdtool

然后就是修改配置文件
client
vi /usr/local/collectd/etc/collectd.conf
Mode    Client
Server 192.168.1.107 1800
LoadPlugin load
LoadPlugin memory
LoadPlugin processes
LoadPlugin swap
LoadPlugin traffic

server
vi /opt/collectd/etc/collectd.conf
Mode    Server
Listen 192.168.1.107 1800
LoadPlugin load
LoadPlugin memory
LoadPlugin processes
LoadPlugin swap
LoadPlugin traffic

        Process java
        Process httpd

两端配置完成后，就可以起服务了

server
/opt/collectd/sbin/collectd

client
/usr/local/collectd/sbin/collectd
当然你也可以用-C 来指定配置文件，比如这样/usr/local/collectd/sbin/collectd -C /root/collectd_server.conf
可以看一下help就知
[root@work_monitor 192.168.1.107]# /usr/local/collectd/sbin/collectd --help
/usr/local/collectd/sbin/collectd: invalid option -- -
Usage: collectd [OPTIONS]

Available options:
General:
    -C        Configuration file.
                    Default: /usr/local/collectd/etc/collectd.conf
    -P        PID-file.
                    Default: /usr/local/collectd/var/run/collectd.pid
    -f              Don't fork to the background.

Builtin defaults:
Config-File       /usr/local/collectd/etc/collectd.conf
PID-File          /usr/local/collectd/var/run/collectd.pid
Data-Directory    /usr/local/collectd/var/lib/collectd
Step              10 seconds
Heartbeat         25 seconds

两边服务起了之后，就可以在server端生成你所需要的rrd文件了，路径在
/opt/collectd/var/lib/collectd下面
一个机器一个文件夹
所生成的rrd文件就可以导入cacti中，cacti就可以出图了
查看rrd数据有无数据
/usr/local/rrdtool/bin/rrdtool fetch /opt/collectd/var/lib/collectd/192.168.1.107/load.rrd AVERAGE -r 900 -s e-30min
