Install Cacti, Spine, Memcached, Better MySQL Cacti Template on FreeBSD 7.2


Cacti… oh.. cacti.. simply monitoring but complex configuration….

Ujian

On this tutorial i would like review how to install cacti. But small differents of previous tutorial. Now, i try out with FreeBSD 7.2. Cacti, Memcached, Spine via ports and Better MySQL Cacti Template.

ok,.. let’s prepare :

Install Cacti:

1. Cacti needs web server and mysql server.
Check this out to install web server and mysql server on FreeBSD 7.2 . Make sure php module enable for webserver (apache2), also sockets, snmp and xml modul for php. Those checked by pkg_info | grep php. If those aren’t system, please install:

# cd /usr/ports/net/php5-sockets; make install clean
# cd /usr/ports/net-mgmt/php5-snmp; make install clean
# cd /usr/ports/net/php5-xmlrpc; make install clean

2. Cacti needs RRD TOOL

to install rrdtool change to into directory below and make install clean

# cd /usr/ports/databases/rrdtool; make install clean

On this step, you can install cacti, please see previous posting how to install cacti (Step 4)

Make sure cacti running fine.. 😉 and then install spine..

Install Spine

Via Ports:

# cd /usr/ports/net-mgmt/cacti-spine
# make install clean

when cacti-spine installed, these package included:

libtool-1.5.26
net-snmp-5.4.2.1_3

Via Source:

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

If you installing cacti-spine via source, please make sure net-snmp installed too

%pkg_info | grep snmp
net-snmp-5.4.2.1_3  An extendable SNMP implementation
# cd /usr/ports/net-mgmt/net-snmp

Please choose one how to install spine. Maybe you need more specific installation when install spine via source if you won’t replace binary spine from port. Use option –prefix=/your/own/folder in example when you type make install.

ok, until here install spine or cacti-id is done. You need hard configuration now !.. 😆

3. 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. Disable crontab poller cacti

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

try to keep your database cacti and rra isn’t gone or error 😀

2. Change poller configuration on cacti
a. Fill path spine
click settings -> Path . u will see like this:

path spine

path spine

then click save

b. change poller configuration

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

poller spine

poller spine

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.

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 *

3. Set crontab time for 1 minutes

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

Finish..

check your log to make sure spine is running .. 😉

spine log

Install memcached and Better MySQL Cacti Templates

We use MySQL Cacti Template for create better Cacti templates for MySQL, Apache, Memcached and more. And we use ssh based templates to create graphics of other machine which snmpd run, so we need create public key and secret key to automatic login on that machine. And next, Install MySQL Cacti Template based ssh:

# tar zxf better-cacti-templates-1.1.4.tar.gz
# cd better-cacti-templates-1.1.4
# cp better-cacti-templates/scripts/ss_get_by_ssh.php /usr/local/www/cacti/scripts/

Now import the template files through your web browser. In the Cacti web interface’s Console tab, click on the Import Templates link in the left sidebar. Browse to the directory containing the unpacked templates, select the XML file for the templates you’re installing, and submit the form. In our example, the file will be named something like cacti_host_template_x_mysql_server_ht_0.8.6i-sver1.1.4.xml. [1]

Configuration:

and then you need set auto login for ssh user as your username. see previous post how to make auto login.

next, need some modified of script:

# cd  /usr/share/cacti/site/scripts/
# vi ss_get_by_ssh.php.cnf
$ssh_user   = 'username';
$ssh_iden   = '-i /your/locate/id_rsa';

done.

On others machine (server monitored, ex: 172.16.0.22) install memcached from ports:

# cd /usr/ports/databases/memcached
# make install clean

start daemon:

/usr/local/bin/memcached -m 4000 -d -u nobody

-m : memori
-d : sebagai daemon
-u : user

boot daemon:

add to rc.conf for memchaced daemon activated every boot.

memcached_enable="YES"
memcached_flags="-t 8 -m 4000"

Testing your ssh based Templates. Run this command on cacti’s machine:

%/usr/local/bin/php /usr/local/www/cacti/scripts/ss_get_by_ssh.php --type memcached --host 172.16.0.22 --items b6,b7
b6:4846539 b7:8779665%
%

and then just create graph for new device and looks like this …

memcached

memcached

Troubleshoot:

If u got an error:

Call to undefined function session_name()

just install via ports:

# /usr/ports/www/php5-session
# make install clean

done…

good luck… 😉

semoga bermanfaat..

🙂
