Monitor Sensu

This repository is to build the monitoring system with Sensu.

Requirement

Vagrant box file(Ubuntu14.04)
Chef-client 11.14 or later
knife solo

About Vagrantfile

Vagrantfile exists to develop and test this reposository in local environment. So you have to change a name of Ubuntu box to ubuntu14_04 or Vagrantfile.

Installation

git clone https://github.com/takanabe/monitor-sensu.git
berks vendor cookbooks
cd ./examples/ssl
 ./ssl_certs.sh generate
mkdir ../../data_bags/sensu
cp ssl.json ../../data_bags/sensu
vagrant up
vagrant ssh-config --host=sensu-server >> ~/.ssh/config
vagrant ssh-config --host=sensu-client1 >> ~/.ssh/config
knife solo bootstrap ec2-user@sensu-server --bootstrap-version 11.16.4
knife solo bootstrap ec2-user@sensu-client1 --bootstrap-version 11.16.4

if you add more clients, please do same as above.

vagrant ssh-config --host=sensu-client2 >> ~/.ssh/config
knife solo bootstrap ec2-user@sensu-client2 --bootstrap-version 11.16.4

Edit check script

To monitor your log file, edit command field included in site-cookbooks/sensu-wrapper/templates/default/checks/check_log.json.erb

For example, if you want chack the logfile named test whether it include the word "WARN", please edit the file like follows:

{
  "checks": {
    "check_log": {
      "handlers": [
        "default"
      ],
        "command": "/etc/sensu/plugins/check-log.rb -f /var/test -r -q WARN",
        "interval": 60,
        "subscribers": ["all"]

Access to Uchiwa

Open a browser you like
Access to 192.168.33.10:3000
Sign in with username&password
user:admin
pass:supersecret

Remaining Tasks

ssh login without key and password(only ec2-user)
it seems to be a waste of time when I use this repository for local dev env
Read check logging and simplify its code, because the code is complicated for new users.
