About

Collectl is a versatile and lightweight performance monitoring tool for Linux systems. It provides comprehensive metrics on system performance and resource utilization, making it useful for administrators and developers who need to monitor various aspects of their systems in real-time or historically. Here’s a detailed overview of Collectl:

Key Features

  1. Comprehensive Metrics:
    • CPU Usage: Provides detailed information on CPU usage, including per-core statistics.
    • Memory Usage: Monitors memory usage, swap usage, and memory page statistics.
    • Disk I/O: Tracks disk read/write operations, throughput, and latencies.
    • Network I/O: Measures network traffic, bandwidth usage, and packet statistics.
    • Processes: Monitors process-level metrics, including CPU and memory usage per process.
  2. Real-Time and Historical Data Collection:
    • Real-Time Monitoring: Collects and displays performance metrics in real-time.
    • Historical Data: Stores collected data for later analysis and trend identification.
  3. Lightweight and Efficient:
    • Minimal Overhead: Designed to have minimal impact on system performance, making it suitable for high-load environments.
    • Efficient Data Collection: Uses efficient data collection methods to avoid excessive resource consumption.
  4. Flexible Data Output:
    • Text Output: Can output data in a plain text format for easy reading and analysis.
    • CSV Export: Supports exporting data in CSV format for use in spreadsheets or other analysis tools.
    • Graphical Tools: Integrates with graphical tools like gnuplot and R for visualizing collected data.
  5. Customizable and Extensible:
    • Configuration Options: Offers various configuration options to tailor data collection and reporting to specific needs.
    • Plugins: Supports plugins for extending functionality and integrating with other monitoring tools.
  6. Historical Data Analysis:
    • Aggregated Reports: Generates reports on historical data to identify trends and analyze performance over time.
    • Graphical Visualization: Supports the creation of graphs and charts for data visualization.
  7. Command-Line Interface:
    • CLI Tool: Provides a command-line interface for collecting and querying performance data.
    • Scriptable: Can be used in scripts and automated monitoring setups.

You can subscribe to Wagtail, an AWS Marketplace product and launch an instance from the product’s AMI using the Amazon EC2 launch wizard.

To launch an instance from the AWS Marketplace using the launch wizard

  • Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/
  • From the Amazon EC2 dashboard, choose Launch Instance. On the Choose an Amazon Machine Image (AMI) page, choose the AWS Marketplace category on the left. Find a suitable AMI by browsing the categories, or using the search functionality. Choose Select to choose your product.
  • A dialog displays an overview of the product you’ve selected. You can view the pricing information, as well as any other information that the vendor has provided. When you’re ready, choose Continue.
  • On the Choose an Instance Type page, select the hardware configuration and size of the instance to launch. When you’re done, choose Next: Configure Instance Details.
  • On the next pages of the wizard, you can configure your instance, add storage, and add tags. For more information about the different options you can configure, see Launching an Instance. Choose Next until you reach the Configure Security Group page.
  • The wizard creates a new security group according to the vendor’s specifications for the product. The security group may include rules that allow all IP addresses (0.0.0.0/0) access on SSH (port 22) on Linux or RDP (port 3389) on Windows. We recommend that you adjust these rules to allow only a specific address or range of addresses to access your instance over those ports
  • When you are ready, choose Review and Launch.
  • On the Review Instance Launch page, check the details of the AMI from which you’re about to launch the instance, as well as the other configuration details you set up in the wizard. When you’re ready, choose Launch to select or create a key pair, and launch your instance.
  • Depending on the product you’ve subscribed to, the instance may take a few minutes or more to launch. You are first subscribed to the product before your instance can launch. If there are any problems with your credit card details, you will be asked to update your account details. When the launch confirmation page displays.

Usage / Deployment  Instructions:

Step 1: SSH into your instance with username ubuntu and key pair to start the application.

ssh -i ssh_key.pem ubuntu@instance-IP

Step 2:  collectl

Step 3: If you want to print statistics for all subsystems, run the command with the –all option:

collectl --all

To use Collectl command work as the top utility, run the following command:
collectl --top

To get the information about TCP and CPU, run the following command:

collectl -stc

Step 4: You can display the information of cpu, disks and network data with the following command:

collectl -scdn

You can successfully installed the collectl using the following steps.Thank You!

    Amazon EC2 enables “compute” in the cloud. Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment. Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change. Amazon EC2 changes the economics of computing by allowing you to pay only for capacity that you actually use.

    Until now, small developers did not have the capital to acquire massive compute resources and ensure they had the capacity they needed to handle unexpected spikes in load. Amazon EC2 enables any developer to leverage Amazon’s own benefits of massive scale with no up-front investment or performance compromises. Developers are now free to innovate knowing that no matter how successful their businesses become, it will be inexpensive and simple to ensure they have the compute capacity they need to meet their business requirements.

    The “Elastic” nature of the service allows developers to instantly scale to meet spikes in traffic or demand. When computing requirements unexpectedly change (up or down), Amazon EC2 can instantly respond, meaning that developers have the ability to control how many resources are in use at any given point in time. In contrast, traditional hosting services generally provide a fixed number of resources for a fixed amount of time, meaning that users have a limited ability to easily respond when their usage is rapidly changing, unpredictable, or is known to experience large peaks at various intervals.

    Traditional hosting services generally provide a pre-configured resource for a fixed amount of time and at a predetermined cost. Amazon EC2 differs fundamentally in the flexibility, control and significant cost savings it offers developers, allowing them to treat Amazon EC2 as their own personal data center with the benefit of Amazon.com’s robust infrastructure.

    When computing requirements unexpectedly change (up or down), Amazon EC2 can instantly respond, meaning that developers have the ability to control how many resources are in use at any given point in time. In contrast, traditional hosting services generally provide a fixed number of resources for a fixed amount of time, meaning that users have a limited ability to easily respond when their usage is rapidly changing, unpredictable, or is known to experience large peaks at various intervals.

    Secondly, many hosting services don’t provide full control over the compute resources being provided. Using Amazon EC2, developers can choose not only to initiate or shut down instances at any time, they can completely customize the configuration of their instances to suit their needs – and change it at any time. Most hosting services cater more towards groups of users with similar system requirements, and so offer limited ability to change these.

    Finally, with Amazon EC2 developers enjoy the benefit of paying only for their actual resource consumption – and at very low rates. Most hosting services require users to pay a fixed, up-front fee irrespective of their actual computing power used, and so users risk overbuying resources to compensate for the inability to quickly scale up resources within a short time frame.
