NOTE: Metric Insights by default installs to /opt. MySQL by default installs to /var. The installer and the application makes use of /tmp. If the three directories live as separate partitions on the host server, please ensure there is adequate disk space to support the application and database.

Metric Insights app directory = /opt/mi
MySQL default directory = /var/lib/mysql
Temp files = /tmp

For disk space requirements, please see What are the system requirements for a Metric Insights server?

3. Operating Systems Supported

3.1. Additional Actions for Operating Systems

Different operating systems require specific additional steps to be performed before and after installation process. Refer to the table below to learn additional commands that should be run for successful package installation.


If you are using a firewall on the linux machine, inbound TCP ports 443 and 8443 are necessary for Metric Insights to work correctly. To open them use the following commands:

Examples for iptables:

iptables -A INPUT -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT
iptables -A OUTPUT -p tcp --sport 80 -m state --state ESTABLISHED -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -m state --state NEW,ESTABLISHED -j ACCEPT
iptables -A OUTPUT -p tcp --sport 443 -m state --state ESTABLISHED -j ACCEPT
iptables -A INPUT -p tcp --dport 8443 -m state --state NEW,ESTABLISHED -j ACCEPT
iptables -A OUTPUT -p tcp --sport 8443 -m state --state ESTABLISHED -j ACCEPT

Examples for ufw:

ufw allow 80/tcp
ufw allow 443/tcp
ufw allow 8443/tcp

Examples for firewall-cmd:

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=443/tcp --permanent
firewall-cmd --zone=public --add-port=8443/tcp --permanent
firewall-cmd --reload
Operating System Additional steps
Centos 6, 7
    1. yum -y update
    2. sudo yum install epel-release
Debian 7 If you cannot get access to ssh root@000.000.000.000, run the following command to verify whether the ssh service has been previously installed:
    service ssh status
If it is installed, the system will return the OK status, informing you that ssh is running. If the system perceives this command as unknown, install ssh servoce on Debian:
    apt-get install ssh
RedHat 7
    1. yum -y update
    2. cd /tmp/
    3. wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
    4. sudo yum install epel-release-latest-7.noarch.rpm
    5. subscription-manager repos --enable=rhel-7-server-optional-rpms

4. Ensure required Linux packages to support the application are available

5. Unpack the downloaded zip archive using the following command

tar -xvf MetricInsights-Installer-<version_number>.tar.gz

6. Change directory to the new install location

cd MetricInsights-Installer-<version_number>

7. Initiate the installation process

./installer.py -vv

NOTE: The installer must be run as root or a user with sudo access.

For additional parameters to use with the installer, please see ./installer.py --help

If you encounter any errors, please contact support@metricinsights.com.

8. Post-checks once the install is complete

Once the installation is complete, confirm the version of Metric Insights from the command line by running this command:

mi-version

Also confirm that major system services for the application are running without issue:

  • MySQL/MariaDB service
  • Apache service
  • Cron service
  • NTP service

Next, log into the UI and confirm the version number in the lower left-hand corner of the homepage. Also check Admin > Status Monitor to get an overview of the application's status.

9. If upgrading by running the installer

First, back up your application before running the installer to upgrade. Run this utility from the command line:

mi-app-backup -vv

By default, the backup file will save to /var/backups/mi-app-backups/. To specify a different path and for additional parameters to use with the utility, please see mi-app-backup --help.
