Security: eMudhra CA compromise
Priority: Low. On October 20, 2026, the private keys for 8 intermediate certificate authorities operated by eMudhra were reported compromised. This is an industry-wide issue, not specific to Coralogix. Update the supervised collector and supervised eBPF profiler to 0.17.0 or later out of an abundance of caution. Coralogix endpoints and internal services do not use eMudhra or emSign certificates, and we have not identified any impact to customer data. Learn more
Overlays for ECS, Host, and Custom configuration groups
Configuration overlays are no longer limited to Kubernetes. Pick the overlay type when you create it, and the target list narrows to configuration groups of that type, so one overlay covers one kind of fleet. Kubernetes, Host, and ECS overlays present the fields of their agent type; a Custom overlay gives you a YAML editor instead and can target any agent type. The type is fixed once the overlay exists, so moving a change to a different agent type means creating a second overlay. Learn more
Apply a configuration overlay on a schedule
An overlay can now apply only inside a scheduled window, so a temporary change such as more log detail during a nightly batch switches itself off without anyone having to remember. Set a start, a duration, and a time zone, repeat the window every N minutes, hours, days, weeks, or months with an optional termination date, and record a reason such as planned maintenance, deployment, migration, or incident response. Outside the window, the targeted groups run their base configuration.
Schedules are all or nothing. An individual window does not have its own Activate and Deactivate, and the overlay's own Activate and Deactivate turn every schedule on it on or off together. An overlay can carry as many schedules as needed, and two of its windows cannot overlap. A configuration change creates a version and the schedules carry over to it, while a change to the schedules alone saves in place without creating one. A new Activate overlay option in the editor turns the overlay on as you save it. Learn more
Restarting a collector is now documented
The agent list carries a Restart collector row action, and the Agent management page now covers it: how to run it, that telemetry still queued on the collector may be lost, and that a queued command means accepted for delivery rather than carried out, so the agent's status is what confirms it came back. It also explains why the action is missing on some rows rather than greyed out.
Manage Fleet configuration groups as code
Define and update Fleet Management configuration groups outside the UI, so changes go through your existing infrastructure-as-code workflows.
Terraform. Manage a configuration group with the coralogix_fleet_configuration_group resource. Learn more
Coralogix Operator. Manage a configuration group with the ConfigurationGroup custom resource in Kubernetes. Learn more
ECS configuration templates
Build OTel Collector configurations for Amazon Elastic Container Service from Fleet Management, alongside the existing Kubernetes and Host templates. Select New configuration on the Configurations tab and pick ECS to get pre-validated YAML and the observability features that suit an ECS deployment. ECS support runs on EC2. Learn more
Configuration overlays
Push one setting change across many configuration groups from a single object, instead of editing each group in turn. Define the change once, select the groups it targets, and activate it; your base configurations stay untouched, so you lift the change back off by deactivating the overlay rather than editing every group back. Before activating, Summary of changes lists the settings that differ for a chosen group and Live preview shows the configuration that group ends up with, as a pipeline diagram or as YAML. Overlays are versioned, and View difference reports how many settings changed between any two versions. Kubernetes configuration groups only for now. Learn more
Configuration fallback path update
Newly activated configurations are now uploaded to the new S3 paths. Previously uploaded configurations remain at their current paths until they are deactivated. The configuration fallback user guide has been updated to reflect these changes. Learn more
Configuration templates and fallback
Configuration templates. Generate production-ready OpenTelemetry Collector configurations from environment-specific templates, without writing YAML from scratch. Learn more
Configuration fallback. Set up S3-based configuration fallback so agents always have a working configuration, even when Fleet Manager is unreachable. Learn more
