How to monitor my server?

You can use “Netdata” tool to monitor your VMs remotely, which is a clean and clear tool.

Install netdata with the following commands: 

Install git-core

Debian / Ubuntu

#  sudo get update

# sudo apt install git-core

CenOS / Fedora

#  sudo yum check-update

# sudo yum install git-core

Clone the Netdata repo
git clone https://github.com/firehol/netdata.git

Change into netdata directory
cd netdata

Make the installscript executable
chmod +x ./kickstart.sh

Run the installscript
./kickstart.sh

It will prompt for pressing “Enter” for complete the installation

It will be installed at these locations:
- the daemon at /usr/sbin/netdata
- config files in /etc/netdata
- web files in /usr/share/netdata
- plugins in /usr/libexec/netdata
- cache files in /var/cache/netdata
- db files in /var/lib/netdata
- log files in /var/log/netdata
- pid file at /var/run/netdata.pid
- logrotate file at /etc/logrotate.d/netdata

Netdata uses port 19999 by default. To enable this port in security group,after the installation , goto your MijndomeinCloud dashboard to check the security group associated with your VM.

Then goto Network--> Security groups--->Manage rules, to add new tcp ingress rule for port 19999.
After adding the rule you should be able to access the netdata dashboard in browser as follows, http://your-public.ip:19999/
