New monitoring graphs not getting enabled on my redis server

Make sure you have DigitalOcean Agent installed on your Droplet. You can do this by executing the following command:

curl -sSL https://agent.digitalocean.com/install.sh | sh

If you already have it, verify the service’s status:

sudo systemctl status do-agent

The output contains information about the process, along with its status, which should report active (running).

systemctl output

   Loaded: loaded (/lib/systemd/system/do-agent.service; enabled; vendor preset: enabled)
   Active: active (running) since Thu 2018-01-18 19:16:17 UTC; 14s ago

   CGroup: /system.slice/do-agent.service
           └─2272 /opt/digitalocean/bin/do-agent -log_syslog

If it’s not running or you still have problems, try to get some logs and open a support ticket. You can find logs in the syslog file, which contains logs for your system and applications.

sudo nano /var/log/syslog

The do-agent-related entries should look like this:
