Package: prometheus-blackbox-exporter
Version: 0.23.0-4+b4
Severity: minor
X-Debbugs-Cc: [email protected]
Dear Maintainer,
I am using MX Linux 23.6, which is based on Debian 12.12.
I have installed the "prometheus-blackbox-exporter" and "prometheus" packages.
When I execute the following command, I get approximately the following error
message.
$ service prometheus-blackbox-exporter start
failed!
Configuration test failed. Output of config test was:
Checking /etc/prometheus/blackbox.yml
FAILED: parsing YAML file /etc/prometheus/blackbox.yml: yaml: unmarshal
errors: line 49: field modules not found in type config.plain
As far as I understand the problem, it is not the configuration file
blackbox.yml, but rather the command that is supposed to check the
configuration file.
The “service” command accesses the file “/etc/init.d/prometheus-blackbox-
exporter”.
To start the service, the function do_start_prepare() is executed, which in
turn executes the function config_check(). In this function, the command
“promtool” is executed, which checks the configuration file
CFGFILE=/etc/prometheus/blackbox.yml.
The problem is that the promtool program, which is designed to check the
prometheus configuration, checks the configuration of the prometheus-blackbox-
exporter. But they are different programs with different configuration files.
My suggestion is to change the following line:
----------------------------------------------------
packet: prometheus-blackbox-exporter_0.23.0-4+b4_amd64.deb
Faulty line 35: errors="$(/usr/bin/promtool check config $CFGFILE 2>&1)" ||
retcode=$?
Corrected line: errors="$(/usr/bin/prometheus-blackbox-exporter --config.check
--config.file $CFGFILE 2>&1)" || retcode=$?
It would be nice if the following text were also displayed in the event of an
error. (After Line 39: echo "$errors" >&2)
Use the command prometheus-blackbox-exporter --config.check to check the
configuration file.
Best regards
Matthias
