Hello @robertkwild
For monitoring switch uplink bandwidth per port and identifying potential bottlenecks, you can use network monitoring tools that support SNMP to gather data from your switches. Additionally, integrating Grafana for visualization is a great idea.
Icinga is another excellent open-source monitoring tool that you can use to monitor your network devices, including switches. It supports SNMP and can be integrated with Grafana for visualization. Here's how you can use Icinga for network monitoring:
- Icinga Core:
Install Icinga Core on your monitoring server. Icinga Core is the core monitoring engine that handles checks, alerts, and notifications.
- Icinga Web 2:
Install Icinga Web 2, which provides a web-based interface for configuration, monitoring, and reporting.
- Icinga Director:
Optionally, you can use Icinga Director, a web-based configuration tool for Icinga, to manage your monitoring configuration.
- SNMP Plugin:
Icinga provides a plugin called `check_snmp` that allows you to perform SNMP queries on your devices. You can use this plugin to collect SNMP data from your switches.
- Integration with Grafana:
Grafana can be integrated with Icinga to visualize the collected data. You can use Grafana's Icinga 2 data source to connect Grafana with Icinga and create dashboards for network monitoring.
