Nemesis has now officially been promoted to the Release Candidate stage and the latest build is available for download.
This release is fully compatible with previous beta versions and existing configuration files, however, we have integrated some additional information in order to more effectively provide data about the operational status of the host machine and the state of the nemesis daemon process.
The telemetry protocol has also been tuned to work with the new administration portal: NemesisHQ scheduled for release in early 2020.
Many thanks to all of our beta testers. We certainly could not have achieved this milestone without your help and feedback.
Welcome to the December 2019 release of the Nemesis engine. After many weeks of various design discussions, development, and testing, we are all very pleased to present to you this latest release code-named: “Garfunkel” (...it’s a deep and dark December).
This version presents a slight departure from our previous architectures and introduces a series of improvements to operational stability while further lowering resource overheads ( CPU / Memory ) required by the system. Network device discovery and reporting tasks have also been more effectively parallelized to improve reliability and resiliency.
In previous releases, certain edge cases could cause the polling engine to crash in ways that could only be fixed by restarting the process or by rebooting the appliance device. Operational stability has been addressed in v1.7.40, and a new recovery model has been introduced to address these situations. It remains our sincere hope to make Nemesis the most fault-tolerant, reliable, Network device monitoring platform ever.
There is still a fair amount of work to do before we can confidently move forward with a Release Candidate, but the sooner we can gather feedback from our beta testers, the better.
The installation package no longer runs the executable as root and grants only a minimum set of capabilites to program and the non-root user under which it executes.
Nemesis daemon v1.7 is here. Although still Beta, this release focuses on stability and bug fixes and will lay the groundwork for our upcoming v1.8 LTS release.
This version of the daemon offers a complete overhaul of the previous network device discovery module with a focus on parallelization and performance.
Benchmark tests for this indicate sub 2 second discovery time on /23 networks (512 nodes) and sub 10 second discovery on /16 (65K nodes).
