Grafana. - 80:80 I know of customers who have a fully virtualized infrastructure but their Icinga Servers are hardware boxes which have their own UPS and SMS gateways attached locally. Even for test i would not recommend it. in a container cluster such as Kubernetes. one main benefit of running applications in containers and layered images is that your base system doesn’t actually install the application, its dependencies, etc. I ask because on the documentation seems like I need other modules…. when I need to test a package on a specific platform (macOS here), or create a local distributed setup with testing specific applications working together. Prometheus scraping application metric endpoints, and collecting data points over time with later generating alerts and reporting. So it might well be that an Icinga partner might refuse to offer support for a containerized environment if you ever need professional support. Also I am currently creating ansible roles for icinga2 and icingaweb2. links: hostname: ${FIRSTNAME}-web-pnp Coming to your initial question - if you plan to use a Docker container just for learning how Icinga works, don’t do that. Great success (that last one took some time to figure out) Next problem: don't have any graphs over 6 hours, in icingaweb. monitoring 2.6.2 There is a variable called ICINGA2_FEATURE_DIRECTOR, if it’s set to zero it disables the module completely. docker run -d -ti --name icinga2-api -p 4080:80 -p 4665:5665 icinga/icinga2 After the container is up and running, connect via HTTP to the exposed port using the credentials root:icinga . can only be run as root, whereas the NRPE service on the remote host runs as a non-privileged user (usually called nagios). ports: Since there is a special volume for modules. However, using the Docker “logs” command is a little primitive, as every time you run docker logs container_id you get all the logs of that process from the beginning. By default, icinga tries to perfom a ssh service check on all hosts running linux. the Director installation should be persistent. What’s special in my dind image? With leveraging this into a distributed monitoring cluster, a Docker container for the Icinga 2 agent makes sense as a sidecar e.g. LAMP stack is a group of open source software components that are used to deploy PHP based applications. Maintaining and upgrading this installation will not be an easy task. Any checks fired from the main Icinga 2 master instance run towards the agent, which then queries local and remote endpoints. docker_check.py. A project by opsdis in category Plugins. build: context: ./web-pnp In order to prevent icinga always showing an error, insert If you find a good advantage that is worth another layer (in this case the container), then do it, otherwise don’t do it. This repository contains the source for the icinga2 dockerimage. - ./${FIRSTNAME}-container/etc/pnp4nagios:/etc/pnp4nagios So you need to enable the Director variable. 3. See my comment at the top of this thread. sharing the workload of web applications, or database backends. - ./${FIRSTNAME}-container/lib/php5/sessions:/var/lib/php5/sessions volumes: Thing is, containers are rather short lived. In case you ever wanted to look at Icinga2, even into distributed features, without messing with installing whole server setups, this might interesting for you. core: About; Puppet; Ansible; Search for: PUPPET, DOCKER, ICINGA AND AWS AUTOMATION – DEPLOYING INSTANCES, CONTAINERS AND MONITORING.
