Icingabeat

The Beats are lightweight data shippers, written in Go, that you install on your servers to capture all sorts of operational data (think of logs, metrics, or network packet data). The Beats send the operational data to Elasticsearch, either directly or via Logstash, so it can be visualized with Kibana.

Icingabeat is an Elastic Beat that fetches data from the Icinga 2 API and sends it either directly to Elasticsearch or Logstash.

Eventstream

Receive an eventstream from the Icinga 2 API. This stream includes events such as checkresults, notifications, downtimes, acknowledgemts and many other types. See below for details. There is no polling involved when receiving an eventstream.

Example use cases:

• Correlate monitoring data with logging information
• Monitor notifications sent by Icinga 2

Statuspoller

The Icinga 2 API exports a lot of information about the state of the Icinga daemon. Icingabeat can poll these information periodically.

Example use cases:

• Visualize metrics of the Icinga 2 daemon
• Get insights how each enable Icinga 2 feature performs
• Information about zones and endpoints

Installation

Download and install your package from the latest release page.

Configuration

Configuration of Icingabeat is split into 3 sections: General, Evenstream and Statuspoller. On Linux configuration files are located at /etc/icingabeat

General

Settings in this section apply to both modes.

host

Hostname of Icinga 2 API. This can be either an IP address or domain. Defaults to localhost

port

Defaults to 5665

user

Username to be used for the API connection. You need to create this user in your Icinga 2 configuration. Make sure that it has sufficient permissions to read the data you want to collect.

Here is an example of an API user in your Icinga 2 configuration:

object ApiUser "icinga" {
  password = "icinga"
  permissions = ["events/*", "status/query"]
}

Learn more about the ApiUser and its permissions in the Icinga 2 docs.

password

Defaults to icinga

skip_ssl_verify

Skip verification of SSL certificates. Defaults to false

Eventstream

Settings in this section apply to the eventstream mode. To disable the eventstream completely, comment out the section.

types

You can select which particular Icinga 2 events you want to receive and store. The following types are available, you must set at least one:

• CheckResult
• StateChange
• Notification
• AcknowledgementSet
• AcknowledgementCleared
• CommentAdded
• CommentRemoved
• DowntimeAdded
• DowntimeRemoved
• DowntimeStarted
• DowntimeTriggered

To set multiple types, do the following:

  types:
    - CheckResult
    - StateChange
    - Notification
    - AcknowledgementSet
    - AcknowledgementCleared

filter

In addition to selecting the types of events, you can filter them by attributes using the prefix event.. By default no filter is set.

Examples

Only check results with the exit code 2:

  filter: "event.check_result.exit_status==2"

Only check results of services that match mysql*:

  filter: 'match("mysql*", event.service)'

retry_interval

On a connection loss Icingabeat will try to reconnect to the API periodically. This setting defines the interval for connection retries. Defaults to 10s

Statuspoller

Settings of this section apply to the statuspoller mode.

interval

Interval at which the status API is called. Set to 0 to disable polling. Defaults to 60s

Run

On Linux systems, use one of the following commands to start Icingabeat:

• service icingabeat start or
• systemctl icingabeat start or
• /etc/init.d/icingabeat start

Dashboards

We have dashboards prepared that you can use when getting started with Icingabeat. They are meant to give you some inspiration before you start exploring the data by yourself. Download the dashboards from the latest release page.

Note: The dashboards require Kibana >= 5.2.0

The tool to import dashboards with is already included in the Icingabeat package.

unzip icingabeat-dashboards-1.1.0.zip -d /tmp
/usr/share/icingabeat/scripts/import_dashboards -dir /tmp/icingabeat-dashboards-1.1.0 -es http://127.0.0.1:9200

Fields

Icingabeat exports a bunch of fields. Have a look to the fields.asciidoc for details.

Development

Building and running manually

Requirements

• Golang 1.7

Clone

To clone Icingabeat from the git repository, run the following commands:

mkdir -p ${GOPATH}/github.com/icinga
cd ${GOPATH}/github.com/icinga
git clone https://github.com/icinga/icingabeat

For further development check out the beat developer guide.

Build

Ensure that this folder is at the following location: ${GOPATH}/github.com/icinga

To build the binary for Icingabeat run the command below. This will generate a binary in the same directory with the name icingabeat.

make

Run

To run Icingabeat with debugging output enabled, run:

./icingabeat -c icingabeat.yml -e -d "*"

Test

To test Icingabeat, run the following command:

make testsuite

alternatively:

make unit-tests
make system-tests
make integration-tests
make coverage-report

The test coverage is reported in the folder ./build/coverage/

Update

Each beat has a template for the mapping in elasticsearch and a documentation for the fields which is automatically generated based on etc/fields.yml. To generate etc/icingabeat.template.json and etc/icingabeat.asciidoc

make update

Cleanup

To clean Icingabeat source code, run the following commands:

make fmt
make simplify

To clean up the build directory and generated artifacts, run:

make clean

Packaging

The beat frameworks provides tools to crosscompile and package your beat for different platforms. This requires docker and vendoring as described above. To build packages of your beat, run the following command:

make package

This will fetch and create all images required for the build process. The whole process can take several minutes to finish.

To disable snapshot packages or build specific packages, set the following environment variables:

export SNAPSHOT=false
export TARGETS="\"linux/amd64 linux/386\""
export PACKAGES=icingabeat/deb
make package

Dashboards

To be able to export dashboards with all their dependencies (visualizations and searches) you have to name the dashboard with a icingabeat- prefix.

Export dashboards:

export ES_URL=http://127.0.0.1:9200
make export-dashboards

After exporting, dashboards can be packaged:

export SNAPSHOT=false
make package-dashboards
