Learn More About Container Monitoring Tools
What are Container Monitoring Tools?
Container monitoring tools monitor running containers, collect container activity logs, and analyze the data to provide observability and insights into container performance.
Containers are ephemeral. It means that they are deleted once their work is complete. So it becomes necessary to continuously collect data and move it to a centralized location to ensure the data is not lost. Container monitoring solutions provide visibility and real-time insights into these highly dynamic containers.
Container monitoring is not very straightforward. Container environments have multiple elements—container hosts, container engines, cluster management systems, and microservices. Failure of any of these elements can affect container performance. This inflates the number of components that container monitoring tools must track. In addition, several layers of abstraction between containers and hardware ensure they can run anywhere. While this is one of the most significant advantages containers offer, monitoring is much more difficult. Containers share resources, which makes monitoring them more tricky. Container monitoring systems can come to the rescue here as they help observe and keep track of the highly elusive containers. Container monitoring systems generally capture metrics such as CPU usage, cache memory usage, network traffic, and time-series data. The information thus collected is compared with preset thresholds to identify anomalies and alert the concerned teams. Most container monitoring tools also provide visualizations and dashboards to enable users to get insights about container health and performance easily.
What Types of Container Monitoring Tools Exist?
The following are the different types of container monitoring tools that exist.
Open-source container monitoring solutions
Open-source container monitoring products often have a lower price point than proprietary software and may even be free. These options may be better for smaller businesses that do not need expansive, feature-rich products. One important point to note is that most open-source products have little or no support staff behind them. So buyers should ensure they have a good in-house development team when implementing one.
Proprietary container monitoring solutions
Proprietary container monitoring software offers more powerful features and performance than open-source software. It also has a more robust support structure for implementation and maintenance. However, it can be expensive. Moreover, some features might be part of the proprietary software package, which is irrelevant to the buyer’s business. This can unnecessarily add up costs.
