first paragraph

the expression "rate(node_network_receive_bytes_total{device="$device"})[$__rate_interval]"

returns an error: bad_data: invalid parameter "query": 1:56: parse error: ranges only allowed for vector selectors

even entering "rate(node_network_receive_bytes_total{device="enp3s0"})[5m]" in the prometheus query editor returns: Error executing query: invalid parameter "query": 1:56: parse error: ranges only allowed for vector selectors

very frustrating!

Note from the Author or Editor:
There's a mistake in the PromQL expression on page 121.

Currently, it reads:
rate(node_network_receive_bytes_total{device="$device"})[$__rate_interval]

But it should be corrected to:
rate(node_network_receive_bytes_total{device="$device"}[$__rate_interval])

The error lies in the positioning of the closing parenthesis. The correct placement ensures the rate function wraps the entire range vector selector.

The URL for the consul_exporter is invalid and returns 404.

Note from the Author or Editor:
An incorrect URL was printed on page 188 for downloading consul_exporter.

Incorrect:
https://github.com/prometheus/consul_exporter/releases/download/v0.3.0/consul_exporter-0.8.0.linux-amd64.tar.gz

Corrected:
https://github.com/prometheus/consul_exporter/releases/download/v0.8.0/consul_exporter-0.8.0.linux-amd64.tar.gz

The error was due to a version mismatch in the URL.
