Cacti optimized spine Polling device

because of the efficiency, when a large amount of data acquisition is required, if the use of the cmd.php poll will be slow, 1 minutes 1 times the acquisition frequency may not complete the polling of all the monitored machines, This may result in the partial monitoring project not showing the graph or the graphics intermittent . In order to solve the efficiency problem, cacti official also launched spine, using multi-threaded way of efficient polling.

1. Solve the dependency relationship
# # dependent on MySQL mysql-devel net-snmp-devel openssl-devel
# # We've installed MySQL mysql-devel when installing cacti so, just install the other 2
# yum-y Install Net-snmp-devel Openssl-devel

2, install spine, download the best version with cacti consistent, spine-0.8.8b
# Tar XF cacti-spine-0.8.8b.tar.gz
# CD CACTI-SPINE-0.8.8B
#./configure
# Make && make install

3. Provide configuration files
# cp/usr/local/spine/etc/spine.conf.dist/etc/spine.conf
# # Edit the configuration file, please modify it according to the actual situation
# vi/etc/spine.conf
Db_host localhost
Db_database CACTIDB
Db_user Cactiuser
Db_pass Cactiuser
Db_port 3306
Db_preg 0

# How did the configuration come about here? Remember, it's cacti/include/config.php.
/* Make sure these values refect your actual Database/host/user/password * *
$database _type = "MySQL";
$database _default = "CACTIDB";
$database _hostname = "localhost";
$database _username = "Cactiuser";
$database _password = "Cactiuser";
$database _port = "3306";
$database _ssl = false;

4. Testing
#/usr/local/spine/bin/spine
spine:using SPINE config file [/etc/spine.conf]
Spine:version 0.8.8b Starting
spine:time:0.1707 s, Threads:5, Hosts:2

5, set the path of the spine
Spine poller File Path, Alternate poller Path, Settings, Configureation, Console
Enter the path to the spine: installed by default in/usr/local/spine/bin/spine

6, modify the cacti default Poller Types
Poller Type, Poller, Cacti Settings, Console
In the drop-down box, select Spine, and then remember "Save"

Note: Spine does not have to add a scheduled task for it, Cacti well spawn Spine every 5 minutes instead of cmd.php
Poller.php needs to define a scheduled task to execute, and then poller.php to dispatch the data collection method.
