Sample configuration for AWS EC2 handling 125k Obcerv entities and 50k metrics/sec (medium) with NGINX Ingress controller
Download this sample AWS EC2 handling 125k Obcerv entities and 50k metrics/sec (medium) configuration provided by ITRS.
# Example Obcerv configuration for AWS EC2 handling 125k Obcerv entities, 50k metrics/sec, and 50k OpenTelemetry
# spans/sec (pre-sampling).
#
# Nodes:
# - (3) m5.4xlarge (16 CPU, 64GiB Memory) for Timescale
# - (4) c5.4xlarge (16 CPU, 32GiB Memory) for all other workloads
#
# The resource requests for Timescale total 24 cores and 182GiB memory.
# The resource requests for the other workloads total ~44 cores and ~98GiB memory.
# These totals include Linkerd resources.
#
# Disk requirements:
# - Timescale:
# - 4 x 1 TiB timeseries data disk for each replica (x3)
# - 100 GiB data disk for each replica (x3)
# - 150 GiB WAL disk for each replica (x3)
# - Kafka: 200 GiB for each replica (x3)
# - Loki: 30 GiB for each replica (x1)
# - Zookeeper: 1 GiB for each replica (x3)
# - etcd: 1 GiB for each replica (x3)
# - Downsampled Metrics:
# - Raw: 5 GiB for each replica (x3)
# - Bucketed: 5 GiB for each replica (x3)
#
# The configuration references a default storage class named `gp3` which uses EBS gp3 volumes. This storage class should
# be configured with the default minimum gp3 settings of 3000 IOPS and 125 MiB/s throughput - you can create
# this class or change the config to use a class of your own, but it should be similar in performance.
#
# This configuration is based upon a certain number of Obcerv entities, average metrics per entity, and
# average metrics collection interval. The following function can be used to figure out what type of load to expect:
#
# metrics/sec = (Obcerv entities * metrics/entity) / average metrics collection interval
#
# In this example configuration, we have the following:
#
# 50,000 metrics/sec = (125,000 Obcerv entities * 4 metrics/entity) / 10 seconds average metrics collection interval
#
# NOTE: Ingestion, storage, and retrieval of OpenTelemetry spans is a beta feature.
#
# Additionally, the configuration is based upon a certain number of OpenTelemetry spans per second that are sampled
# based upon the following rules:
# - Error traces are always sampled
# - Target sampling probability per endpoint (corresponds to the name of the root span) is 0.01
# - Target sampling rate / second / endpoint (corresponds to the name of the root span) is 0.5
# - Root span duration outlier quantile is 0.95. The durations of all root spans are tracked and used to make guesses about
# abnormally long spans
