# Monitoring with Nagios
|
|
|
|
## Context
|
|
|
|
Implementation of a monitoring solution for MediaSante: Nagios deployment with custom probes and log centralization with Rsyslog.
|
|
|
|
## Objectives
|
|
|
|
- Install and configure Nagios Core
|
|
- Create custom monitoring probes
|
|
- Centralize logs with Rsyslog
|
|
- Define SLA indicators and produce reports
|
|
|
|
## Technologies Used
|
|
|
|
- **Nagios Core**: infrastructure monitoring
|
|
- **NRPE**: remote probe execution
|
|
- **Rsyslog**: log centralization
|
|
- **SNMP**: network monitoring
|
|
|
|
## Configured Probes
|
|
|
|
| Service | Warning Threshold | Critical Threshold | Operator Action |
|
|
|---------|-------------------|-------------------|-----------------|
|
|
| CPU | > 80% | > 95% | Identify consuming processes |
|
|
| RAM | > 85% | > 95% | Check memory leaks |
|
|
| Disk | > 80% | > 90% | Cleanup or extension |
|
|
| HTTP | latency > 2s | unavailable | Service restart |
|
|
| MySQL | connections > 80% | > 95% | Query analysis |
|
