# Get status of a specific unit
Here I have requested the status of the currently running `mongodb` unit:
```
$ systemctl status mongod
mongodb.service - MongoDB Database Server
Loaded: loaded (/usr/lib/systemd/system/mongodb.service; enabled; preset: disabled)
Active: active (running) since Wed 2022-08-17 07:25:27 BST; 24h ago
Docs: https://docs.mongodb.org/manual
Main PID: 931 (mongod)
Memory: 304.1M
CPU: 2min 18.630s
CGroup: /system.slice/mongodb.service
└─931 /usr/bin/mongod --config /etc/mongodb.conf
Aug 17 07:25:27 archbish systemd[1]: Started MongoDB Database Server.****
```
In addition to the core info it tells us the unit type. In this case it is a
service.
We can also view the journal entry for the given unit. This provides you with
its diagnostic log messages:
```
journalctl --unit=mongodb.service
