Revolutionized Monitoring Solution for B2B Products Company with 400 Servers
Key Results
The Challenge
The client was using Nagios as their monitoring solution for approximately 400 servers across Linux and Windows infrastructure in a hybrid setup. Nagios's static configuration made it cumbersome to integrate into automated provisioning processes and lacked scalability. The periodic check-based approach didn't provide real-time monitoring capabilities, creating delays between issue occurrence and detection. The legacy monitoring system couldn't accommodate the dynamic cloud environment and required extensive manual configuration for each new server.
Our Solution
We implemented a comprehensive modern monitoring stack based on Prometheus with multiple layers of monitoring. The solution included HTTP endpoint monitoring with Blackbox Exporter, APM for code behavior analysis, system metrics monitoring with Node Exporter, and specialized exporters for MySQL, Redis, and RabbitMQ. We automated inventory management using IMDB APIs to build Ansible hosts inventory, implemented EC2 service discovery for automatic node detection, and configured intelligent alerting to Slack and PagerDuty.
The Results
The transformation provided real-time monitoring capabilities with instant issue detection instead of periodic delays. The automated discovery eliminated manual configuration when new nodes were provisioned, significantly reducing operational overhead. Multiple monitoring layers provided comprehensive visibility from HTTP endpoints down to database performance. Intelligent alerting ensured the operations team was immediately notified of issues through Slack and PagerDuty, enabling proactive problem resolution before customers were impacted.
Customer Overview
Our customer is a USA-based B2B solutions provider with a vast infrastructure of approximately 400 servers including both Linux and Windows systems. These servers are hosted in a hybrid setup, utilizing both their internal data center and cloud providers, creating a complex monitoring challenge.
Challenge
The client faced two major problems with their existing monitoring solution:
Nagios Limitations
Static Configuration Issues
Nagios is not designed to accommodate dynamic environments. Its configuration is static, which makes it cumbersome and complex to integrate into automated provisioning processes. Every new server required manual configuration changes, creating operational bottlenecks.
Scalability Problems
It is widely acknowledged that Nagios lacks scalability as one of its key weaknesses. As the infrastructure grew to 400+ servers, the limitations became increasingly apparent with slow UI responsiveness and configuration management nightmares.
Real-Time Monitoring Gaps
Periodic Check Delays
Nagios primarily relies on periodic checks, which means it may not provide real-time monitoring capabilities out of the box. Depending on the configuration, there can be significant delays between the occurrence of an issue and its detection.
Reactive Approach
The delays meant that customers often reported issues before the monitoring system detected them, leading to reactive rather than proactive problem resolution.
Solution
Monitoring is a crucial part for any mission critical applications. This helps identify issues even before customers call and complain about the website, enabling teams to proactively fix any potential problems and avoid business impact.
Multi-Layer Monitoring Approach
Our solution contains multiple levels of monitoring to ensure comprehensive visibility:
HTTP Monitoring
Endpoint Availability
- Monitor any endpoint like website homepage or API endpoints
- Check for successful response codes
- Measure response times and latency
- Alert in case of any failure
- Track SSL certificate expiration
APM (Application Performance Monitoring)
Code Behavior Analysis
- Identify issues on how code is behaving in production
- Detect memory leaks before they cause outages
- Identify deadlocks in multi-threaded applications
- Monitor heap/stack memory usage
- Track backend performance metrics
- Analyze database query performance
System Monitoring
Infrastructure Health
Critical metrics are monitored for systems where code is running, whether web servers, application servers, or database servers:
- CPU utilization and load averages
- Memory usage and swap activity
- Disk usage and I/O performance
- Network throughput and errors
- Process monitoring
Implementation Highlights
Build Inventory
Automated Inventory Management
All the servers and their related information was available in their IMDB (Infrastructure Management Database). We used the IMDB API to build Ansible hosts inventory automatically, eliminating manual inventory maintenance.
Effortless Prometheus Setup
Expert Configuration
Our team specializes in Prometheus configuration and set up Prometheus with precision. The installation was smooth and hassle-free, enabling the client to start monitoring their systems immediately with minimal disruption.
Node Exporter Installation Made Easy
Ansible Automation
Leveraging our proficiency in Ansible, our expert engineers developed a powerful playbook that effortlessly installs the Node Exporter on various EC2 machines and on-premise servers. We eliminated manual installation steps and embraced automation for efficient monitoring.
Key Features
- Idempotent playbooks for safe re-execution
- Support for both Linux and Windows systems
- Automatic service configuration
- Version management and updates
Auto Discovery of New Nodes
EC2 Service Discovery
With our expertise in Prometheus, we implemented EC2 service discovery to enable automatic detection of any newly provisioned nodes. The system is seamlessly monitored without manual intervention when new nodes are added.
Benefits
- Zero-touch onboarding for new instances
- Automatic tagging and labeling
- Dynamic target updates
- Reduced operational overhead
Expanded Monitoring Capabilities
Our expert engineers went beyond the basics and set up additional exporters for enhanced monitoring:

- Monitor cache hit/miss ratios
- Track memory usage and eviction rates
- Stay informed about vital Redis metrics
RabbitMQ Exporter
Message Queue Monitoring
- Seamlessly integrated RabbitMQ Exporter
- Created dedicated scrape job for messaging systems
- Monitor queues, exchanges, and bindings
- Track message rates and consumer performance
- Monitor with ease for messaging infrastructure
Blackbox Exporter
External Monitoring
- Implemented Blackbox Exporter for URL monitoring
- Monitor all important URLs and endpoints
- Check HTTP/HTTPS response codes
- Measure DNS lookup times
- Validate SSL certificates
- Ensure critical web services are constantly checked
Intelligent Alerting
Multi-Channel Notifications
To ensure critical system events are never missed, our expert engineers configured alerts to be sent to various notification channels:
Slack Integration
- Real-time alerts to dedicated Slack channels
- Color-coded severity levels
- Actionable alert messages with context
- Alert acknowledgment tracking
PagerDuty Integration
- Critical alerts routed to PagerDuty
- On-call rotation management
- Escalation policies for unacknowledged alerts
- Integration with incident management workflows
