Install Monit

Overview

The install_monit.sh script is designed to monitor and start critical processes, including Hub and Probe in the event of unexpected termination. This ensures continuous data collection and processing, minimizing downtime and data loss.

Requirements

• Ensure Monit is installed in your system

Usage

NetFlow Customers

The script is installed in /usr/local/share/trisul-hub; run it from there. Use -x once for each context you do not want monitored. The examples below exclude contexts named netflow and context0; replace them with your own context names.

To configure process monitoring for NetFlow customers, run the script with the following arguments:

./install_monit.sh -n hub0 -p probe0 -x netflow -x context0

IPDR Customers

For IPDR customers, add the -d option to the command:

./install_monit.sh -n hub0 -p probe0 -x netflow -x context0 -d

How it Works

• The script adds the specified processes (Hub and Probe) to the Monit configuration file, /etc/monitrc or /etc/monit/monitrc, whichever exists.
• Monit checks the status of these processes every minute.
• If a process is found to be not running, Monit automatically restarts it.

Important Notes: The script assumes that the Monit service is already installed and configured on the system. The -d option is specific to IPDR customers and should not be used for NetFlow customers.

Options

Option	Default value	Description
-d		Monit IPDR process
-x		Exclude a context from being monitored
-n	hub0	Hub node
-p	probe0	Probe node
-h		Shows Help

Example: ./install_monit.sh -n hub0 -p probe0 -x netflow -x context0 -d
