Nagios vs Thanos: What are the differences?

Developers describe Nagios as "Complete monitoring and alerting for servers, switches, applications, and services". Nagios is a host/service/network monitoring program written in C and released under the GNU General Public License. On the other hand, Thanos is detailed as "Highly available Prometheus setup with long term storage capabilities". Thanos is a set of components that can be composed into a highly available metric system with unlimited storage capacity. It can be added seamlessly on top of existing Prometheus deployments and leverages the Prometheus 2.0 storage format to cost-efficiently store historical metric data in any object storage while retaining fast query latencies. Additionally, it provides a global query view across all Prometheus installations and can merge data from Prometheus HA pairs on the fly.

Nagios and Thanos can be categorized as "Monitoring" tools.

Some of the features offered by Nagios are:

  • Monitor your entire IT infrastructure
  • Spot problems before they occur
  • Know immediately when problems arise

On the other hand, Thanos provides the following key features:

  • Global querying view across all connected Prometheus servers
  • Deduplication and merging of metrics collected from Prometheus HA pairs
  • Seamless integration with existing Prometheus setups

Nagios and Thanos are both open source tools. Thanos with 3.83K GitHub stars and 429 forks on GitHub appears to be more popular than Nagios with 60 GitHub stars and 36 GitHub forks.

  • modern interface and architecture
  • large community
  • extendable I knew Nagios for decades but it was really outdated (by its architecture) at some point. That's why Icinga started first as a fork, not with Icinga2 it is completely built from scratch but backward-compatible with Nagios plugins. Now it has reached a state with which I am confident.
