Using Glances Tool to Monitor Unix Systems

Overview

Sometimes Kerio Connect may experience performance-related problems (CPU/RAM spikes, unstable overall User experience, system lags, etc.). This article provides information on how to monitor the system in-depth for Troubleshooting Performance Issues in Kerio Connect.

Prerequisites

• Kerio Connect being installed on Linux (Debian, Centos) or macOS, this article does not apply to Windows.
• Root access to the server.

Process

1. Depending on your operating system (OS), install the Glances tool.
   • Linux
   • macOS
   Glances is a Python made open source project for system monitoring.
2. Open the Command Prompt or the Terminal app.
3. Type the following command.
    
   

   glances -export csv -export-csv-file "~/location/file.csv"

   Replace ~/location with your actual folder name. This command exports all the results into a CSV file.
4. Observe the reported issue while the Glances tool is running.
   
   You might leave the tool running while experiencing the issue a couple of times. Please capture the exact date and time of the performance-related issues (RAM/CPU drops, system glitches, etc.) that you are experiencing.
5. Supply the above information, along with the resulting CSV file to the Support Team for further assistance.
