Sample configuration for micro sized cluster with NGINX Ingress controller (micro, no HA)

Warning

Beginning with ITRS Analytics 2.14.2, the Micro t-shirt size is now supported for production deployments.

This update is not backward compatible. To use Micro in production, you must upgrade to ITRS Analytics version 2.14.2 or newer.

Download this sample Micro sized cluster with NGINX Ingress controller configuration provided by ITRS for installations with High Availability (HA) disabled.

# Example ITRS Analytics configuration for micro-sized instance handling ~100,000 entities, ~400,000 time series,
# ~3000 datapoints/sec (tested with approximately 2200 metrics/sec, 800 logs/sec, 10 signals/sec, 10 audit events/sec);
# and ~3000 span/sec (pre-sampling).
# Actual ingestion composition may vary by deployment.
# No HA and with nginx Ingress controller.
#
# The resource requests total ~18 cores / ~51 GiB requests (~60 cores / ~72 GiB limits)
# These totals include optional Linkerd sidecar resources
#
# It is recommended to use a storage class with defaults of 3000 IOPS and 125 MiB/s throughput.
#
# DISK REQUIREMENTS:
# Estimated disk requirements based on default retention and the ingestion rate above
# (actual size will vary depending on the shape of the data being ingested).
# - Kafka: 100 GiB
# - Kafka controller: 10 GiB
# - Postgres: 3 GiB
# - ClickHouse Keeper: 2 GiB
# - ClickHouse Platform: 20 GiB
# - ClickHouse Metrics: 200 GiB
# - ClickHouse Logs: 60 GiB
# - ClickHouse Traces: 30 GiB
# - etcd: 16 GiB
