Public Metrics

Overview

Metrics play a crucial role in monitoring and analyzing the performance of Oxla, enabling users to gain valuable insights into their data processing and analytics workflows. The metrics are specific to a single node.

This documentation will guide you on how to access and leverage the metrics.

All metrics exposed by Oxla have a label_node_id with a node ID set. This is the same node_id that can be found in logs and on data storage.

Accessing Metrics

Once you have successfully deployed Oxla, you can access the comprehensive metrics that provide valuable insights into the performance and health of your database. To access the metrics, follow the steps below:

Open your preferred web browser and enter the following URL:

<ip>:8080/metrics

Replace <ip> with the actual IP address of your Oxla deployment. For example, if your Oxla instance is hosted on IP address 128.128.1.1, the URL would be:

128.128.1.1:8080/metrics

If you are running Oxla locally on your machine, you can use localhost as the IP address. In that case, the URL would be:

localhost:8080/metrics

Upon accessing the URL, you will be presented with various metrics as shown below:

# HELP exposer_transferred_bytes_total Transferred bytes to metrics services
# TYPE exposer_transferred_bytes_total counter
exposer_transferred_bytes_total 0
# HELP exposer_scrapes_total Number of times metrics were scraped
