Logging and Monitoring Tools

Logging and monitoring tools are critical components of any modern software infrastructure, giving information about system behaviour, performance, and faults. Here’s a summary of their main tools:

Site24X7:

For IT teams and DevOps, Site24x7 is a cloud-based solution for IT monitoring, alerting, and reporting. It offers support for a variety of verticals, including:

Server monitoring, Cloud monitoring, Network monitoring, Application monitoring, Real user monitoring, Website monitoring.

Site24x7 offers both free and paid monitoring services for an entire IT environment. It can remotely monitor websites and alert users if a website goes down. It also provides weekly reports on the performance of monitored websites.

Site24x7 is a product of Zoho Corp., which was previously known as AdventNet Inc.. It has integrated data centers in the US, European Union, India, China, Australia, and Japan.

Promethus:

Prometheus Monitoring is a free, open-source tool that monitors computer systems and applications. It collects and stores system performance data in a time-series database. This data can be used to identify and diagnose problems, set up alerts, and optimize systems

Prometheus is particularly useful for monitoring Kubernetes clusters. It can also be used to monitor applications, microservices, and networks, including service meshes and proxies.

Prometheus has several advantages, including:

Service discovery: Service discovery: Kubernetes and Prometheus are integrated, allowing Prometheus to locate all services and retrieve metrics from Prometheus endpoints.
Always works: Prometheus continues to work even if other parts of the infrastructure are broken.
Fast outage discovery: Prometheus allows for fast outage discovery.
No extensive setup: Prometheus doesn’t require extensive setup.

Prometheus is well suited for working with time series data and drawing insights from it. It’s also one of the best tools for monitoring running databases.

Prometheus collects metrics, individual identifiers, and timestamps. It has four primary metric types: counters, gauges, histograms, and summaries. The official Prometheus client libraries for Go, Java, Ruby, and Python contain these metric types.

Prometheus exposes data in a basic style, with a new line for each statistic and separated by line feed characters.

Grafana:

Grafana is a free, open-source, interactive data visualization platform that allows users to see their data through charts and graphs. It is often used in DevOps environments to visualize and analyze data from various sources.

Grafana allows users to:

Query, visualise, alert, and investigate metrics, logs, and traces.
Convert time-series database (TSDB) data into graphs and visualisations.
Unify data into one dashboard for easier interpretation and understanding

Nagios:

Nagios is a free, open-source software programme for monitoring systems, networks, and infrastructure.. It’s a legacy IT infrastructure monitoring tool that focuses on server, network, and application monitoring.

Nagios can monitor systems, services, applications, and business processes in a DevOps context. It performs rapid tests and is simple to configure on the client and server sides.

Nagios is designed to run on the Linux operating system and can monitor devices running Linux, Windows, and Unix OSes. It periodically checks crucial parameters of application, network, and server resources.

Nagios can also monitor an assortment of metrics on many different virtualization platforms, such as VMware, Microsoft Virtual PC, Xen, and Amazon EC2.

Some reasons to use Nagios include:

Detects all network or server faults.
Helps you to find the root cause of the problem
Actively monitor your entire infrastructure and business processes.
