spine: a backend data gatherer for cacti

This code represents high speed poller replacement for cmd.php. It has come quite a ways from it’s initial development. It is 100% compatible with the legacy cmd.php processor. (Larry Adams aka TheWitness)

Prepare:

1. Make sure net-snmp-devel package have been installed on your machine.

# rpm -qa | grep snmp

on my machine results:

net-snmp-5.4.1-77.4
snmp-mibs-5.4.1-77.4
libsnmp15-5.4.1-77.4
php5-snmp-5.2.9-0.1
net-snmp-devel-5.4.1-77.4

if you dont have anything of package, install using yast. yeah, i’m using rh based / opensuse 11.

# yast2 -i net-snmp

2. Get package from www.cacti.net

# cd /usr/src
# wget http://www.cacti.net/downloads/spine/cacti-spine-0.8.7c.tar.gz

Installation spine:

1. extract package

# tar -xzvf cacti-spine-0.8.7c.tar.gz

2. Configure, make and make install :)

# cd cacti-spine-0.8.7c
# ./configure && make && make install

Configuring spine:

0. Copying spine.conf and configuring it

# cd /usr/local/spine/etc
# cp spine.conf.dist spine.conf

# vi spine.conf
DB_Host         localhost
DB_Database     cacti
DB_User         cactiuser
DB_Pass         cactipassword
DB_Port         3306

1. Set crontab time for 1 minutes

* * * * * /usr/bin/php /srv/www/htdocs/cacti/poller.php > /dev/null 2>&1

2. Change poller configuration on cacti</strong>

a. Fill path spine

click settings -> Path . u will see like this:

then click save

b. change poller configuration

click settings -> Poller . u will see like this:

then click save

others configuration:

1. Update value of poller on database

default value of poller on cacti database are 300 seconds. We can change that value via mysql console

# mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 28894
Server version: 5.0.77-community MySQL Community Edition (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

change into cacti database

mysql> use cacti;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed

and update value of poller on database.

mysql> update data_template_data set rrd_step='60';
mysql> update data_template_rrd set rrd_heartbeat='120';
mysql> flush privileges;

2. Remove rra data on rra directory.</strong>

Remove old rra data that does not confuse with the new data of spine poller. Backup first if u not sure what r u doing.

# cd /srv/www/htdocs/cacti/rra
# tar -czvf /srv/www/htdocs/backup-rra.tar.gz *

then u can remove rra data

# rm *

Finish..

check your log to make sure spine is running .. ;)

Troubleshooting:

if u got error like below when using spine version cacti-spine-0.8.7/a/c

configure: error:


*** [Gentoo] sanity check failed! ***
*** libtool.m4 and ltmain.sh have a version mismatch! ***
*** (libtool.m4 = 1.5.22, ltmain.sh = 1.5.26) ***

try using spine version 7c beta 2 on this page

gud luck ;)
