Utilizing industry-standard tools such as Nagios, Zabbix, or SolarWinds to continuously monitor network devices, including routers, switches, firewalls, and servers. Employing SNMP (Simple Network Management Protocol) to collect real-time performance metrics such as bandwidth utilization, packet loss, latency, and device health status. Implementing custom monitoring scripts and probes to detect anomalies and performance degradation, enabling proactive intervention before issues escalate. Utilizing threshold-based alerting mechanisms to notify administrators of potential network disruptions or security breaches promptly. Employing SNMP traps and syslog monitoring to capture and analyze log data for troubleshooting and forensic analysis.
Leveraging packet capture and analysis tools such as Wireshark or tcpdump to diagnose network issues and identify root causes. Conducting traceroute and pathping tests to analyze network paths and pinpoint connectivity bottlenecks or routing issues. Performing SNMP walks and MIB (Management Information Base) analysis to identify misconfigured devices or abnormal behavior. Employing remote access technologies such as SSH (Secure Shell) or Telnet to troubleshoot and configure network devices remotely. Collaborating with network engineers and service providers to troubleshoot WAN (Wide Area Network) connectivity issues and ISP (Internet Service Provider) routing problems.
