Monitoring IT infrastructure is a complicated activity, as there are multiple devices and factors involved —each of which needs to be given its due importance. Some of the critical factors that can result in degradation of IT performance include:

• Excessive CPU utilization and inconsistent hardware health and availability.
• Mismanaged bandwidth consumption between individual devices.
• Misconfigurations during updates or upgrades to IT infrastructure.
• Lack of adherence to essential compliance measures.
• Ineffective or outdated firewall rules and policies.

As you can see, crafting a clearly defined IT infrastructure monitoring strategy is essential to ensure your organization's IT infrastructure functions efficiently. Now let us talk about,

• Components of IT infrastructure monitoring
• IT infrastructure monitoring challenges

Components of IT infrastructure monitoring

IT infrastructure monitoring can be divided into five individual components which includes,

Physical and virtual infrastructure monitoring

Physical and virtual infrastructure monitoring deals with ensuring the health, availability, and optimum performance of all critical devices in a network. It includes network monitoring, server monitoring, and monitoring of the health and performance of virtual devices, such as those from VMware, Hyper-v, and Nutanix. Physical and virtual infrastructure monitoring is not just restricted to devices but also extends to monitoring the various processes and services that run on these devices. Monitoring health and availability is an important aspect that helps in reducing downtime and optimizing the performance of the entire IT infrastructure, thereby resulting in a highly efficient IT infrastructure management strategy.

Bandwidth monitoring

Tracking bandwidth consumption is another important aspect of monitoring IT infrastructure that helps optimize the availability and performance of devices in an IT infrastructure. Bandwidth management must happen at both the infrastructure level (for individual devices based on their capacity and criticality) and at the global, network level (tracking and defining global traffic patterns). Proactive bandwidth consumption planning, coupled with active, real-time monitoring of network traffic patterns, is key to ensure your IT infrastructure does not succumb to the pitfalls of mismanaged bandwidth usage.

Change monitoring

Planning a clearly defined change implementation and management process is critical to ensure your IT infrastructure environment remains well-protected from disasters due to misconfigurations. “Change” in this context refers not just to configuration changes (implemented at the individual infrastructure level) but also security-level alterations (firewall rules, policies, etc.).

Any change, irrespective of its nature, size, significance, and implications, must be quantified, assigned a well-defined approval hierarchy, and preceded by a backup of existing changes. The entire change management process must also be evaluated at the user level to ensure only IT admins with appropriate privileges can implement changes.

Log monitoring

You need to proactively monitor logs from your organization ’s IT infrastructure to detect and identify critical network faults. Analyzing various types of logs, including syslogs, event logs, and firewall logs, helps in both optimizing performance as well as detecting security threats.

IP address monitoring

Periodic scanning and monitoring of IP addresses in your IT infrastructure is key to ensure rogue devices do not intrude into your network environment. It also helps in avoiding havoc-wreaking network issues like IP address collision.

IT infrastructure monitoring challenges

While there is no doubt that having a clearly defined strategy can help your organization get the most out of every penny invested in its IT infrastructure and ensure that the business does not suffer losses due to network issues, monitoring IT infrastructure does have its challenges. This includes:

• Dealing with the complexities of a multivendor environment: Devices from different vendors might have different critical parameters. You must monitor the critical metrics under each aspect such as bandwidth monitoring, availability monitoring etc irrespective of the vendor heterogeneity among devices and processes.
• Designing proactive monitoring strategies: For a real-time IT infrastructure monitoring strategy to be efficient, it has to be proactive. This is achieved through in-depth analysis of critical parameters and connecting the dots between inferences from multiple components to arrive at the bigger picture.
• Managing licensing for multiple IT monitoring tools: Your organization needs a unified tool that supports the various infrastructure monitoring components discussed above. In the absence of a single tool for the entire process, you’ll be tasked with the additional challenge of finding the right set of IT infrastructure monitoring tools, then implementing and managing those tools’ licenses to ensure that monitoring for critical devices is not disrupted due to license issues.

Best practices to monitor your infrastructure efficiently

To ensure the maximum efficiency of an IT infrastructure monitoring strategy, the following best practices are recommended:

1. Establish a secure, well-defined user-access system where the right IT admin has access to the right set of real-time data that allows them to monitor quickly and resolve IT infrastructure faults while ensuring no compromise in security.
2. Periodically analyze critical metrics and foresee unprecedented issues with the help of reports. This lets technicians take proactive, informed measures in order to prevent them from occurring thereby improving the performance.
3. Monitor critical devices and metrics constantly. This allows to take immediate remedial measures for IT infrastructure faults and helps prevent business losses.
4. Automate repetitive maintenance tasks to save a ton of time and resources overhead and effectively use manpower for troubleshooting critical issues.

Key elements of IT Infrastructure Monitoring

A few key elements of IT infrastructure monitoring are discussed below to obtain an optimal level of performance.

• Infrastructure Prioritization: Prioritizing critical devices and critical metrics in your IT infrastructure plays a vital role in effective monitoring and troubleshooting. Given that an IT infrastructure may be composed of hundreds of thousands of components, prioritization allows proper planning and execution of a stable IT operations monitoring strategy. It allows IT technicians to prioritize network issues and fix them accordingly.
• Unified licensing model: A Unified licensing model helps save on overhead cost and time. Thus eliminating tracking of multiple licenses which creates more complexity and workload.
• Security & privacy: As the complexity of the network increases, security becomes a key element of IT infrastructure monitoring. Monitoring and management privileges should be provided only to essential stakeholders. Users must be carefully categorized based on their roles (such as admin, operator, etc) and efforts must be taken to ensure that there is no unauthorized access to data during the IT infrastructure monitoring process.

Types of IT Infrastructure Monitoring

Agent-less monitoring

Agent-less methodology of IT infrastructure monitoring in a network allows IT admins to gain insights into IT performance through direct polling of network devices from the monitoring tool. By establishing direct contact with network infrastructure, this method of monitoring eliminates the need for overheads/agents, thus saving time, effort, and resources that can be used for proactively optimizing other critical aspects of IT infrastructure.

Agent-based monitoring

Agent-based monitoring lets IT admins collect data on critical metrics of your network devices periodically with the help of an agent. An agent is a small, lightweight software installed on devices. It monitors the devices round the clock and updates their status instantly to the server in real-time. This methodology reduces the load on the server and helps improve its performance.
