SKALE 3.0.1 upgrade

This document describes the procedure for upgrading from 3.0.0 to 3.0.1 release.

New monitoring pipeline

In 3.0.1 release we added new metrics collection pipeline.

In the 3.0.0 release, we have introduced a new metrics collection pipeline. The Telegraf service (https://github.com/influxdata/telegraf) will be deployed on the nodes, pushing various node metrics to a database server hosted by the SKALE Core team. The metrics collected include:

  • CPU usage of the host and each service.

  • RAM usage of the host and each service.

  • Disk performance data.

  • Various internal SKALE service metrics.

Firewall rules should be adjusted to allow outgoing 8391 port.

Telegraf configuration can be found here https://github.com/skalenetwork/skale-node/blob/stable/telegraf.conf.j2 .

It is possible to use telegraf for your own needs. However currently custom configuration will be reset after each skale node update execution.

In the next releases we are planning to provide more metrics and enhance the healthcheck API.

If you have any questions regarding the new pipeline feel free to communicate with us through dedicated channel.
