Consolidate Nagios alerts from across multiple sites into a single "at-a-glance" console. Nagios 3 and Nagios 4 are now supported.
Transform this ...
Into this ...
You'll need the following system packages to Install nagios-alerta:
In RedHat/CentOS/Fedora:
yum install -y git curl gcc make libcurl-devel jansson-devel
In Debian/Ubuntu:
apt-get install -y git-core curl gcc make libcurl4-openssl-dev libjansson-dev libglib2.0-dev pkg-config
$ git clone https://github.com/alerta/nagios-alerta.git
$ cd nagios-alerta
$ make
$ sudo make install
$ sudo service nagios restart
$ git clone https://github.com/alerta/nagios-alerta.git
$ cd nagios-alerta
$ make nagios4
$ sudo make install
$ sudo service nagios restart
To forward host and service check results to Alerta,
modify /etc/nagios/nagios.cfg as follows:
broker_module=/usr/lib/nagios/alerta-neb.o http://localhost:8080
To specify the environment name:
broker_module=/usr/lib/nagios/alerta-neb.o http://localhost:8080 env=ENV_NAME_HERE
To specify the customer name:
broker_module=/usr/lib/nagios/alerta-neb.o http://localhost:8080 customer=CUSTOMER_NAME_HERE
To provide the API key if authentication is enabled on the alerta server:
broker_module=/usr/lib/nagios/alerta-neb.o http://localhost:8080 key=INSERT_API_KEY_HERE
To forward check results in Hard state only:
broker_module=/usr/lib/nagios/alerta-neb.o http://localhost:8080 hard_only=1
And to enable debug mode:
broker_module=/usr/lib/nagios/alerta-neb.o http://localhost:8080 debug=1
Note: The default environment is Production and the default service is Platform.
Use custom object variables
_Environment and _Service to set environment and service on a
per-check basis:
define host{
use generic-host ; Name of host template to use
host_name localhost
alias localhost
address 127.0.0.1
_Environment Development
_Service Network
}
define service{
use generic-service ; Name of service template to use
host_name localhost
service_description Total Processes
_Environment Production
_Service Web
check_command check_procs!250!400
}
Use custom object variables to set customer_views
define host{
use generic-host ; Name of host template to use
host_name localhost
alias localhost
address 127.0.0.1
_Customer Customer1
}
define service{
use generic-service ; Name of service template to use
host_name localhost
service_description Total Processes
_Customer Customer1
check_command check_procs!250!400
}
To configure the Nagios server to send regular heartbeats to Alerta to ensure that Nagios and the event broker are still forwarding alerts configure a dummy service check as follows:
- Define a heartbeat command and add it to
/etc/nagios/commands.cfg:
define command{
command_name check_heartbeat
command_line /usr/lib/nagios/plugins/check_dummy 0
}
- Define a hostgroup for the Nagios servers that have the Alerta event
broker installed and add it to
/etc/nagios3/conf.d/hostgroups_nagios2.cfg:
define hostgroup {
hostgroup_name nagios-servers
alias Nagios servers
members localhost
}
- Define a Heartbeat service check to execute every minute and add it
to
/etc/nagios/conf.d/services_nagios2.cfg:
define service {
hostgroup_name nagios-servers
service_description Heartbeat
check_command check_heartbeat
use generic-service
notification_interval 0 ; set > 0 if you want to be renotified
normal_check_interval 1
}
