What diagnostic tools have you used in your past roles?


Basic Network Tools

  • Ping – Checks if a device is reachable on the network and measures response time. Used when verifying connectivity to a server or device.

  • Traceroute – Shows the path packets take to reach a destination. Used to diagnose network routing issues or delays.

  • nslookup – Looks up DNS records for a domain or IP address. Used when troubleshooting name resolution problems.

  • netstat – Displays active network connections and listening ports. Used to monitor open ports and active sessions on a device.

Advanced Network Tools

  • Wireshark – Captures and analyzes network traffic in detail. Used to investigate complex network issues or monitor suspicious traffic.

  • Nmap – Scans networks for active devices and open ports. Used for network discovery, auditing, or security checks.

  • SolarWinds Network Performance Monitor – Provides real-time network health and bandwidth usage stats. Used for continuous network monitoring in larger environments.

Hardware Testing Tools

  • Fluke Network Testers – Tests network cable quality, signal, and wiring standards. Used during installation or troubleshooting of physical cabling.

  • Cable Continuity Testers – Checks if the wires in a cable are connected properly end-to-end. Used when verifying if a patch cable or cable run is intact.

System & Server Monitoring

  • Nagios – Monitors servers, network devices, and alerts on failures. Used for proactive monitoring of IT infrastructure.

  • Zabbix – Similar to Nagios but with advanced graphing and monitoring. Used for detailed monitoring of performance metrics and alerts.

  • SNMP Tools – Gathers information from network devices using SNMP protocol. Used for monitoring device status, like routers, switches, or printers.

Remote Access Tools

  • PuTTY / SSH Clients – Connects securely to servers over SSH. Used for remote command-line access and troubleshooting.

  • RDP (Remote Desktop Protocol) – Provides remote GUI access to Windows systems. Used for full desktop access during remote support or maintenance.

  • VNC (Virtual Network Computing) – Provides remote desktop access across platforms. Used for GUI access to systems, often in mixed environments.

Log Analysis Tools

  • Syslog Servers / Graylog – Collects and analyzes logs from various devices. Used for centralized logging and tracking of system events.

  • Event Viewer (Windows) – Shows logs related to system events, errors, and security. Used for diagnosing issues on Windows systems.

  • journalctl / syslog (Linux) – Views system logs on Linux-based systems. Used for troubleshooting and system audits on Linux servers.


What are common safety protocols in a data center environment?


Common Safety Protocols in a Data Center

  1. Access Control

    • Restrict entry to authorized personnel only using badges, biometrics, or keycards.

    • Maintain visitor logs and escort non-employees at all times.

  2. Personal Protective Equipment (PPE)

    • Use anti-static wrist straps and grounding mats when handling sensitive equipment.

    • Wear safety shoes, gloves, and eye protection as needed.

  3. Proper Handling of Equipment

    • Follow manufacturer guidelines for lifting heavy servers or components to avoid injury.

    • Use appropriate tools for installation and maintenance.

  4. Fire Safety

    • Install fire detection and suppression systems (e.g., smoke detectors, FM200 gas suppression).

    • Keep fire extinguishers accessible and staff trained on their use.

  5. Electrical Safety

    • Ensure power is off before working on electrical components unless using approved live-work procedures.

    • Use insulated tools and avoid water or conductive materials near equipment.

  6. Environmental Controls

    • Monitor temperature and humidity to prevent overheating or condensation.

    • Keep aisles and exits clear to avoid trip hazards and enable quick evacuation.

  7. Cable Management

    • Secure cables to prevent tripping and reduce risk of damage.

    • Avoid overloading power outlets and use surge protectors.

  8. Emergency Procedures

    • Clearly post evacuation routes and emergency contact information.

    • Conduct regular drills and training for staff on emergency response.

  9. Regular Audits and Inspections

    • Routinely check safety equipment, signage, and compliance with protocols.

    • Promptly address any hazards or violations.
