Promtail [DEPRECATED]

DEPRECATION NOTICE

Grafana Promtail has been deprecated and is no longer maintained by Big Bang.

Big Bang will be migrating to Grafana Alloy as the core log collector.

Overview

Promtail is an agent which reads log files and sends streams of log data to the centralised Loki instances along with a set of labels.

Big Bang Touch Points

Architecture:

• Promtail Client

Storage

Promtail does not persist data, and instead reads log files and streams the data to a log aggregation system.

Istio Configuration

Istio is disabled in the promtail chart by default and can be enabled by setting the following values in the bigbang chart:

istio:
  enabled: true

These values get passed into the promtail chart here.

High Availability

By default, Promtail runs as a daemonset with a pod on each node.

Single Sign on (SSO)

None. This service doesn’t have a web interface.

Licensing

Promtail utilizes an AGPLv3 License for it’s code and binaries.
