Benchmark

This repository consists of kubernetes manifests for otel-collector and node-exporter. These manifests can be used to generate time-series data in SigNoz cluster. We can plot graphs in the Dashboard from SigNoz UI.

Using Helm

The metrics-benchmark helm chart uses single Node-Exporter alongside Nginx for cache. It deploys Otel-Collector which scrapes data simulated hosts with unique host labels.

1. Change directory to charts/metrics-benchmark:

cd charts/metrics-benchmark

2. Use Makefile to helm install:

make install

*Note: In case of SigNoz cluster running in different cluster, replace my-release-clickhouse.platform.svc.cluster.local in values.yaml with appropriate accessible address.

Example Manifests

We have two types of manifests:

• Single-Node-Expoter: runs single instance of Node-Exporter and Otel-Collector as Deployment.
• Multiple-Node-Expoters: runs multiple instance of Node-Exporter as DaemonSet and Otel-Collector as Deployment.

1. Create benchmark namespace:

kubectl create ns benchmark

2. Change directory to manifests:

cd manifests

3. You can either create Node-Exporter as Deployment or DaemonSet:

# For Deployment, cd to single-node-exporter
cd single-node-exporter

# Alternatively for DaemonSet, cd to multiple-node-exporters
cd multiple-node-exporters

4. Create Node-Exporter resources:

kubectl apply -n benchmark -f node-exporter/

5. Create Otel-Collector resources:

kubectl apply -n benchmark -f otel-collector/

*Note: In case of SigNoz cluster running in different cluster, replace my-release-clickhouse.platform.svc.cluster.local in otel-collector/config.yaml with appropriate accessible address.
