Graphite: Instalasi

Sumber: https://www.digitalocean.com/community/tutorials/how-to-install-and-use-graphite-on-an-ubuntu-14-04-server

Instalasi

sudo apt-get update
sudo apt-get install graphite-web graphite-carbon

Jika di tanya "Carbon to remove the database files" bisa jawab "No" jika kita tidak ingin data yang sudah ada hilang. Jika ini merupakan instalasi yang fresh / baru, kita bisa jawab "Yes".

Install PostgreSQL

sudo apt-get install postgresql libpq-dev python-psycopg2

Buat Database User dan Database

sudo -u postgres psql

Buat database graphite, user graphite dengan password graphite

CREATE USER graphite WITH PASSWORD 'graphite';
CREATE DATABASE graphite WITH OWNER graphite;
\q

Konfigurasi Graphite Web Application

Edit

sudo nano /etc/graphite/local_settings.py
sudo vi /etc/graphite/local_settings.py

Set SECRET_KEY dengan password yang panjang, unik, dan aman, misalnya

SECRET_KEY = '123456'
SECRET_KEY = 'UNSAFE_DEFAULT'
SECRET_KEY = 'a_salty_string'

Set TIME_ZONE

TIME_ZONE = 'Asia/Jakarta'

Set USE_REMOTE_USER_AUTHENTICATION

USE_REMOTE_USER_AUTHENTICATION = True

Set DATABASES

DATABASES = {
    'default': {
        'NAME': 'graphite',
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'USER': 'graphite',
        'PASSWORD': 'graphite',
        'HOST': '127.0.0.1',
        'PORT': 
    }
}

Save konfigurasi

Sync Database

Ketik

sudo graphite-manage syncdb

Akan keluar dan perlu di isi

You just installed Django's auth system, which means you don't have any superusers defined.
Would you like to create one now? (yes/no): yes
Username (leave blank to use 'root'): 
Email address: onno@indo.net.id
Password: 
Password (again):

Konfigurasi Carbon

Carbon adalah Graphite storage backend.

Edit

sudo nano /etc/default/graphite-carbon
sudo vi /etc/default/graphite-carbon

Pastikan

CARBON_CACHE_ENABLED=true

Save file.

Edit

sudo nano /etc/carbon/carbon.conf
sudo vi /etc/carbon/carbon.conf

Aktifkan log rotation, dengan

ENABLE_LOGROTATION = True

Save file.

Konfigurasi Storage Schemas

Edit

sudo nano /etc/carbon/storage-schemas.conf
sudo vi /etc/carbon/storage-schemas.conf

Di dalamnya, akan ada entry seperti berikut,

[carbon]
pattern = ^carbon\.
retentions = 60:90d

[default_1min_for_1day]
pattern = .*
retentions = 60s:1d

Bisa juga di tambahkan

[test]
pattern = ^test\.
retentions = 10s:10m,1m:1h,10m:1d

yang akan menyimpan setiap 10 detik, selama 10 menit dst.

Save.

Metoda Agregasi Storage

Copy contoh konfigurasi

sudo cp /usr/share/doc/graphite-carbon/examples/storage-aggregation.conf.example /etc/carbon/storage-aggregation.conf

Edit

sudo nano /etc/carbon/storage-aggregation.conf
sudo vi /etc/carbon/storage-aggregation.conf

This looks a bit similar to the last file. You will find entries that look like this:

[min]
pattern = \.min$
xFilesFactor = 0.1
aggregationMethod = min

Nama section dan pattern sama dengan storage-schemas file.

Save file.

Start Carbon Cache

sudo service carbon-cache start

Instalasi dan Konfigurasi Apache

Install apache

sudo apt-get install apache2 libapache2-mod-wsgi

Disable virtual host file

sudo a2dissite 000-default

Copy Graphite Apache virtual host file ke site directory

sudo cp /usr/share/graphite-web/apache2-graphite.conf /etc/apache2/sites-available

Enable virtual host file

sudo a2ensite apache2-graphite

Reload apache,

sudo service apache2 reload

Atau dalam satu klik

sudo apt-get install apache2 libapache2-mod-wsgi

sudo a2dissite 000-default
sudo cp /usr/share/graphite-web/apache2-graphite.conf /etc/apache2/sites-available
sudo a2ensite apache2-graphite
sudo service apache2 reload

Cek Web

Browse ke

http://server_domain_name_or_IP
http://192.168.0.100

Kondisi server dapat dilihat di

Graphite > carbon > agents > .... > cache

Coba kirim data

Data dikirim menggunakan TCP. Cara paling sederhana menggunakan nc

echo "test.count 3 `date +%s`" | nc -q0 192.168.0.100 2003

Format data yang dikirim kita-kira

test.count 3 1456194469

Data dikirim secara realtime.
