mongodb_exporter.service TLS is disabled

[l0rdaxel]

Hello everyone, I have a problem with the mongodb_exporter.service to export metrics to Grafana.

It is configured as follows:

###############################à
[Unit]
Description=MongoDB Exporter
User=prometheus

[Service]
Type=simple
Restart=always
ExecStart=/usr/local/bin/mongodb_exporter --mongodb.uri=mongodb://mongodb_exporter:collaudo@xxx:27017/admin?ssl=true

[Install]
WantedBy=multi-user.target
###############################

But when I start mongodb_exporter.service, I get this output:

###############################

My MongoDB cluster is configured on 3 nodes (one primary and two secondary) and SSL connection is enabled.

In fact, if I try to connect with a client with the following string, I can connect without problems mongodb://mongodb_exporter:collaudo@xxx:27017/?authSource=admin&readPreference=primary&appname=MongoDB%20Compass&ssl=true

My prometeus.yml is:

###############################

global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.

Could you please help me solve this issue?
Thanks!
