Arbiter uptime absent

[superset1]

Hello In version 0.37.0, the MongoDB arbiter does not have mongodb_instance_uptime_seconds metrics or other similar metrics uptime I have to install the old version 0.11.2 for arbiter

To Reproduce Steps to reproduce the behavior:

1. download release 0.37.0
2. configure systemd unit

[Unit]
Description=Prometheus exporter for MongoDB (https://github.com/percona/mongodb_exporter)
After=network.target mongod.service

[Service]
Type=simple
RestartSec=5s
Restart=on-failure
User=mongodb-exporter
Group=mongodb-exporter
ExecStart=/usr/local/bin/mongodb-exporter --discovering-mode --mongodb.direct-connect --mongodb.uri=mongodb://mongodbexporter:[email protected]:27017/admin
ExecStop=/bin/kill -s SIGINT $MAINPID

[Install]
WantedBy=multi-user.target

Also I tried --compatible-mode --collector.diagnosticdata --collector.collstats

Expected behavior I expect that metrics uptime will be available.

Environment

• debian 10,
• MongoDB version
  • 4.4.18
  • 6.0.4
