HetrixTools - Linux Server Monitoring Agent Issues – Incident details

We’ve identified an issue in our Linux Server Monitoring Agent that occurs when Daylight Saving Time ends (in autumn). If the server where the agent is installed is not configured to use the UTC timezone, the agent will fail to collect metrics during the repeated (backward) hour.

This only affects the following versions of our Linux Server Monitoring Agent:

• 2.3.1

• 2.3.2

• 2.3.3

• 2.3.4

The issue stems from how the agent scheduler uses the server's time to run the agent every one minute; a scheduler that won't fire up when the hour turns backwards.

A solution has been implemented for this with version 2.3.5 of our Linux Server Monitoring Agent.

You can easily update your agent with the following command:

wget -4 -qO- https://raw.githubusercontent.com/hetrixtools/agent/master/hetrixtools_update.sh | sudo bash
