Netdata v1.18.1 releases, real-time performance and health monitoring system

2 days ago ddos

Netdata is distributed, real-time, performance and health monitoring for systems and applications. It is a highly optimized monitoring agent you install on all your systems and containers.

Netdata provides unparalleled insights, in real-time, of everything happening on the systems it runs (including web servers, databases, applications), using highly interactive web dashboards. It can run autonomously, without any third party components, or it can be integrated to existing monitoring tool chains (Prometheus, Graphite, OpenTSDB, Kafka, Grafana, etc).

Netdata is fast and efficient, designed to permanently run on all systems (physical & virtual servers, containers, IoT devices), without disrupting their core function.

Netdata is free, open-source software and it currently runs on Linux, FreeBSD, and MacOS.

Changelog v1.18.1

Release v1.18.1 contains 17 bug fixes, 5 improvements, and 5 documentation updates.

At a glance

Patch release 1.18.1 contains several bug fixes, mainly related to FreeBSD and the binary package generation process.

Netdata can now send notifications to Google Hangouts Chat!

On certain systems, the slabinfo plugin introduced in v1.18.0 added thousands of new metrics. We decided the collector’s usefulness to most users didn’t justify the increase in resource requirements. This release disables the collector by default.

Finally, we added a chart under Netdata Monitoring to present a better view of the RAM used by the database engine (dbengine). The chart doesn’t currently take into consideration the RAM used for slave nodes, so we intend to add more related charts in the future.
