How to Setup Shinken Monitoring Tool on ECS Ubuntu 18.04

In this tutorial, we will learn how to install and configure Shinken on an Alibaba Cloud Elastic Compute Service (ECS) instance with Ubuntu 18.04.

By Hitesh Jethva, Alibaba Cloud Community Blog author.

Shinken is a free and open source system and network monitoring framework written in python and based on Nagios core. It works by monitoring hosts and services, gathers performance data and alerts users when error conditions occur. Shinken can be scaled to the LAN, through the DMZs and even across several data centers. It is used to monitor different network services and host resources such as processor load, disk usage, system log, and memory usage.

In this tutorial, we will learn how to install and configure Shinken Monitoring Tool on Ubuntu 18.04 server with an Alibaba Cloud Elastic Compute Service (ECS) instance.

Prerequisites

  • Two fresh Alibaba Cloud instance with Ubuntu 18.04 server installed.
  • A static IP address 192.168.0.11 is set up on the server instance and 192.168.0.249 is setup on the client instance.
  • A root password is set up on both instances.

Launch Alibaba Cloud ECS Instance

Create a new ECS instance, choosing Ubuntu 16.04 as the operating system with at least 2GB RAM, and connect to your instance as the root user.

Once you are logged into your Ubuntu 18.04 instance, run the following command to update your base system with the latest available packages.

apt-get update šCy

Getting Started

Before starting, you will need to install some required packages to your system. You can install all of them with the following command:

apt-get install python-pip python-pycurl python-cherrypy3 python-setuptools git -y

Next, add user for Shinken with the following command;

useradd -m -s /bin/bash shinken

Install Shinken Server

First, you will need to download the latest version of Shinken from Git repository. You can download it with the following command:

git clone https://github.com/naparuba/shinken.git

You should see the following output:

Cloning into 'shinken'...
remote: Enumerating objects: 70916, done.
remote: Total 70916 (delta 0), reused 0 (delta 0), pack-reused 70916
Receiving objects: 100% (70916/70916), 48.88 MiB | 181.00 KiB/s, done.
Resolving deltas: 100% (51043/51043), done.

Change the directory to the shinken and checkout the latest branch with the following command:

cd shinken

git checkout 2.4.3

Install Shinken server by running the following command:

python setup.py install

Once the installation has been completed successfully, you should see the output "Shinken setup done".

Next, start the Shinken service with the following command:

/etc/init.d/shinken start

You can check the status of Shinken service with the following command:

/etc/init.d/shinken status

Install Shinken Web Interface

You will need to install Webui2 (Shinken Web Interface) using the shinken command.

First, log in with shinken user:

su - shinken

Next, initialize the shinken configuration with the following command:

shinken --init

Install Webui2 with the following command:

shinken install webui2

Exit from the shinken user and install MongoDB and other python package with the following command:

apt-get install mongodb
pip install pymongo>=3.0.3 requests arrow bottle==0.12.8

You will need to define webui2 module in broker-master.cfg file. You can do this with the following command:

nano /etc/shinken/brokers/broker-master.cfg

Make the following changes:

modules     webui2

Save and close the file. Then, open admin.cfg file and set your admin password:

nano /etc/shinken/contacts/admin.cfg

Make the following changes:

contact_name    admin      
password        password

Install Nagios-plugins

You will need to install Nagios-plugins to your system. You can do this with the following command:

apt-get install nagios-plugins* cpanminus

Install the required Perl modules with the following command:

cpanm Net::SNMP
cpanm Time::HiRes
cpanm DBI

Create new link for utils.pm file to shinken the directory and create a new directory for Log_File_Health:

chmod u+s /usr/lib/nagios/plugins/check_icmp
ln -s /usr/lib/nagios/plugins/utils.pm /var/lib/shinken/libexec/
mkdir -p /var/log/rhosts/
touch /var/log/rhosts/remote-hosts.log

Log in to shinken user and ssh and linux-snmp for monitoring SSH and SNMP with the following command:

su - shinken
shinken install ssh
shinken install linux-snmp

Add Monitoring Host

You will need to configure a new Linux host to monitored from Shinken server.

First, log in to Shinken client instance and Install the snmp and snmpd packages with the following command:

apt-get install snmp snmpd -y

Next, open snmpd.conf file and make some changes:

nano /etc/snmp/snmpd.conf

Make the following changes:

#agentAddress  udp:127.0.0.1:161
agentAddress udp:161,udp6:[::1]:161
#rocommunity mypass  default    -V systemonly
#rocommunity6 mypass  default   -V systemonly
rocommunity password

Save and close the file. Then, start the snmpd service with the following command:

systemctl start snmpd

Next, you will need to define the new host on Shinken server instance.

Go to the Shinken server instance and create a new file /etc/shinken/hosts/host-one.cfg:

nano /etc/shinken/hosts/host-one.cfg

Add the following lines:

define host{
        use                 generic-host,linux-snmp,ssh
        contact_groups      admins
        host_name           host-one
        address             192.168.0.249
        _SNMPCOMMUNITY      password        # SNMP Pass Config on snmpd.conf
    }

Save and close the file. Then, open SNMP configuration file:

nano /etc/shinken/resource.d/snmp.cfg

Make the following changes:

$SNMPCOMMUNITYREAD$=password

Save and close the file. Then, restart Shinken service with the following command:

/etc/init.d/shinken restart
