Icinga

Icinga2 is an excellent contender in the monitoring world

Kommentare: Monitoring is a question to be considered carefully -- rarely is a solution one-size-fits-all. Icinga2 is a great option for basic monitoring.

Vorteile:

Icinga2 fills a niche very similar to that of the Nagios project. Where Icinga excels (over Nagios) is in the niceties of its configuration language, as well as many advanced features. As an open source project, Icinga offers a free, open, and complete solution for most operation monitoring. In particular, Icinga is great for monitoring hosts and alerting on basic metrics.

Nachteile:

There are a few disadvantages of Icinga -- the frontend is php, the stack is fairly monolithic, and the architecture does not take advantage of time-series databases. Having used (and set up) both monolithic monitoring infrastructure and pipelined infrastructure, I have found that although the monolithic (nagios/icinga2) systems have a much lower barrier to entry, a pipelined architecture tends to be more maintainable for more advanced requirements.

A cloud-native jack of all trades

Kommentare: Easy to deploy, in a cloud-native fashion using Icinga satellites, provides the core functionality nicely that anyone in their right mind is expecting from a monitoring system, but might lack some things that larger enterprises consider "mandatory".

Vorteile:

Icinga is, even though it's already at this point in time a relatively mature open source project, getting updates released very frequently. It seems to be increasing the feature upside it has over its most direct competition, slowly, but surely. The API is also more straightforward in design over its direct competition.

Nachteile:

Graphs and visualization over longer time periods is really lacking or if existing, really difficult to use. The .conf file configuration also feels very old school now in 2021.

Easy to use

Vorteile:

Easy to use, to install. HA capability and satellite usage are greats features Windows Installation

Nachteile:

Reporting features are not great. If we need to create some reports of Availability module are not reporting somes informations or graph Grafana / graph integration is not easy Documentation is not complete Windows Integration and check are not easy to use. It will be great to install with the agent the powershell checks

My experience using Icinga for my clients

Kommentare: I've used this tool for a number of firms, monitoring anything from standard server response to ensuring that specialised daemons are up and functioning. Icinga's client/server architecture allows it to monitor almost anything for which you can create a script. You may monitor local CPU, RAM, processes, and more without using SNMP by installing the client on a server. TLS encryption is used to encrypt communication between the client and the server, offering security where it is often lacking. Icinga has been used to monitor network and system devices throughout the whole organisation.

Vorteile:

Beautiful Web User-Interface, Highly Configurable and Scalable, The secure connections between systems are possible thanks to the client/server concept. It also permits data to be captured even if there is a communication problem, with the data being queued for upload when communication is restored.

Nachteile:

Sometimes io2db process fails and the UI freezes, Configuration can be hard for non-unix users and this leads to hours of search surfing but if the documentation got improved things will go smooth.

The ultimate tool for server monitoring

Kommentare: After getting past the initial hurdle of setup, the software worked exactly as advertised and allowed our company to have much better monitoring of our servers. It has also allowed us to get much more information about these servers than before that helps us determine business priorities.

Vorteile:

The build-in icingaweb plugin is great and allows our less-technical employees to still use this application. Initial set-up can be tricky, but the community following is great and generally very helpful. Extending the number of hosts or services checked is a breezy, with easy "clone this object" functionalities on the web interface, or detailed customization for the sysadmin. The fact that you can customize alerting for a specific time of day for your various users is a life-saver.

Nachteile:

As stated before, the initial set-up is tricky, with varying steps needed depending on the OS it is running on. Also, installing an agent on the servers that need to be monitored requires some trial and error. As with any complicated piece of software, the learning curve is quite steep.
