How To Fix prometheus-varnish-exporter: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu prometheus-varnish-exporter is provided by prometheus-varnish-exporter package.

prometheus-varnish-exporter is:

Prometheus exporter for Varnish metrics.

prometheus-varnish-exporter scrapes the varnishstat -j JSON output on each Prometheus collect and exposes all reported metrics. Metrics with multiple backends or Varnish defined identifiers (e.g. VBE..happy SMA..c_bytes LCK..creat) and other metrics with similar structure (e.g. MAIN.fetch_) are combined under a single metric name with distinguishable labels. Vanish naming conventions are preserved as much as possible to be familiar to Varnish users when building queries, while at the same time trying to following Prometheus conventions like lower casing and using _ separators.

To fix this problem, we can install more using the command below.

sudo apt-get -y install prometheus-varnish-exporter
