What is LibreNMS?

LibreNMS is in maintenance mode, with point releases that fix or revert rather than add.

LibreNMS is an open-source network monitoring system on a monthly release train. Its last four releases are all bug-fix point releases: a billing-polling fix, a custom-map rollback, a revert for older fping versions, and one release with no notes.

What is SigNoz?

SigNoz sets November 11 to drop v1 alert rules and ships Telegram alerts and GCP logs.

SigNoz ships a weekly changelog led by API deprecation notices. The October 22 edition sets November 11 for removing the v1 alert rule schema and endpoints, with stored rules rewritten to v2alpha1 on upgrade, and confirms the v1 alert-history endpoints are gone. It also moves saved views into the Explorer sidebar, rebuilds Notification Channels on the v2 API with richer Slack formatting, and adds Telegram alerts and GCP log collection.

LibreNMS vs SigNoz: editorial side-by-side

5.0

LibreNMS is in maintenance mode, with point releases that fix or revert rather than add.

◆ Current state

LibreNMS is an open-source network monitoring system on a monthly release train. Its last four releases are all bug-fix point releases: a billing-polling fix, a custom-map rollback, a revert for older fping versions, and one release with no notes.

◆ Where it's heading

Recent work is about stability, not scope. The project pulled the half-finished custom-map icon backgrounds and reverted a change that broke older installs, which suggests a cautious posture toward regressions in the field. These entries show no new capability.

◆ Prediction

The next monthly release will likely bring another round of polling and map fixes. The entries don't show where feature work is heading.

5.0

SigNoz sets November 11 to drop v1 alert rules and ships Telegram alerts and GCP logs.

◆ Current state

SigNoz ships a weekly changelog led by API deprecation notices. The October 22 edition sets November 11 for removing the v1 alert rule schema and endpoints, with stored rules rewritten to v2alpha1 on upgrade, and confirms the v1 alert-history endpoints are gone. It also moves saved views into the Explorer sidebar, rebuilds Notification Channels on the v2 API with richer Slack formatting, and adds Telegram alerts and GCP log collection.

◆ Where it's heading

SigNoz is retiring its v1 alerting API in stages, history first and rules next, while widening where alerts go (Jira, incident.io, now Telegram) and what it ingests. The August plugin for AI coding agents remains its main directional bet; recent weeks are platform cleanup around it.

◆ Prediction

Expect weekly reminders until November 11, then a release that removes v1 rules. Further alert channels and cloud-integration log sources are the likely feature follow-ups.
