Centos7 Monit configure to monitor disk space usage detail report

These steps will guide how to add Disk Storage monitor report into the Monit web access

First, you need to know which drive you want to be included into the Monit  report by following command

df

For example here I have one partition /dev/vda1 and I want to monitor it with the usage detail.

Update the Monit configuration file

Now open the monit config file by the path: /etc/monit.d/storagespace 

Create that file if it is not existed. Paste the following content

check filesystem Ubuntu with path /dev/vda1
    if space usage > 90% then alert

If you have multiple volumes, easy that clone those 2 lines in multiple breakdown. Note that Ubuntu is the optional name you want to be showed as alias name in report.

Done, save it.

Check and Restart Monit process

Check the configuration file is ok by command

sudo monit -t

It will output *Control file syntax OK* means fine, otherwise try to review again your config file.

Restart monit service

systemctl restart monit

Check for status of service

systemctl status monit

So everything is fine, now point to web browser to access monit report, by default port is 2812 and your url will look like http://<host>:2812

The monit monitoring my disk right now, so click on it will go to details

Finished!
