Network Troubleshooting Technique #3: Traceroute
Network Troubleshooting Technique #3: Traceroute

Traceroute is a network troubleshooting technique that helps identify the path that network packets take from the source device to the destination device. It works by sending a series of packets to the destination device, with each packet having a different time-to-live (TTL) value. Each router along the path to the destination device decrements the TTL value, and if it reaches zero, it discards the packet and sends an ICMP "Time Exceeded" message back to the source device.

Traceroute uses the ICMP protocol to identify the routers along the path to the destination device, and it reports the IP address, hostname, and response time of each router. This information helps network administrators identify the location of network issues and diagnose latency or connectivity problems.

what is network troubleshooting - traceoute

Some of the uses of traceroute as a network troubleshooting technique include:

  • Identifying network routing issues: Traceroute helps identify routing issues by reporting the IP address and hostname of each router along the path to the destination device.
  • Identifying network latency issues: The response time reported by traceroute helps identify latency issues and can help identify where delays are occurring along the path to the destination device.
  • Diagnosing connectivity issues: Traceroute can help diagnose connectivity issues by identifying where packets are dropping or being lost along the path to the destination device.

Traceroute is a valuable network troubleshooting technique that can help administrators identify and resolve network issues. However, it does have limitations. For example, some routers are configured to block ICMP packets, which can result in incomplete traceroute reports. Additionally, traceroute only reports the path taken by network packets and does not provide detailed information about the nature of network issues.

  • How to solve problems for a quick and smooth fix.

Network Troubleshooting Step 3. Isolate the Network Problem
Network Troubleshooting Step 3. Isolate the Network Problem

To begin the network troubleshooting process, you've got to catch and isolate the network problem.

To do this, compare the monitoring sessions you created from deploying Obkio's NPM tool.

A. If’s Not a Network Issue
A.  If’s Not a Network Issue

As a reference, below is an example of a Network Session with no network problems.

network troubleshooting

If you're not experiencing a network problem, it might be a user issue. In this case, you can troubleshoot by installing a Monitoring Agent directly on a user’s workstation (the user who is experiencing the performance problems) to see the issue from their point-of-view.

If you still don’t find that it’s a network problem at this point, it may just be a problem that IT specialists can troubleshoot and resolve directly on the user's workstation or on the remote destination. The problem could be several other hardware-intensive videoconferencing systems, which use up a lot of resources (CPU, RAM).

Obkio monitors these other resource metrics as well.

B. Check for A Network Problem On 2 Network Sessions

how to Troubleshoot network issues

A. Check your Network Hardware
A. Check your Network Hardware

Believe it or not, many network problems may be caused by faulty hardware, bad physical connections, or incorrect configurations. When you begin the troubleshooting process, check all your hardware to make sure it’s correctly connected, turned on, and working.

If a cord has come loose or has broken, or somebody has switched off an important router, this could be the problem behind your network issues. There’s no point in going through the process of troubleshooting network issues if all you need to do is replace a cord, so make sure all switches are in the correct positions and haven’t been bumped accidentally.

Here are some general network troubleshooting steps for network hardware that can help you identify and resolve network issues:

  1. Check physical connections: Ensure that all physical connections are secure and correctly plugged in. Loose or damaged cables can cause network connectivity issues.
  2. Restart devices: Power cycle the affected devices, including the router, switch, and modem. Sometimes, this can resolve the issue by resetting the devices and clearing out any temporary network configurations.
  3. Check network settings: Verify that the network settings, including IP addresses, subnet masks, and default gateways, are correctly configured. Misconfigured network settings can cause connectivity issues.
  4. Update firmware and software: Ensure that the devices and software used in the network are updated to the latest versions. Newer versions can contain bug fixes and performance improvements that can resolve network issues.

Going through to check every cord one-by-one can be tiresome and a gigantic loss of time. Thankfully, a network performance monitoring software like Obkio monitors problems within your network interface that are commonly caused by hardware!

B. Check for CPU or Bandwidth Issues
B. Check for CPU or Bandwidth Issues

When you compare your previous data with Device Monitoring metrics, you may find CPU or Bandwidth issues. These resource issues likely means that the network issue is on your end and you need to troubleshoot internally.

Here are a few network troubleshooting suggestions got CPU or bandwidth issues:

  1. Traffic Analysis: Examine your firewall logs to determine if the traffic passing through your network is legitimate. This will help identify potential security breaches such as data exfiltration or improper data backup during business hours.

  2. Firewall Management: Prioritize important traffic in order to reduce congestion during periods of high traffic. This ensures that traffic to and from critical applications is given priority and is less likely to cause network congestion.

  3. Bandwidth Upgrade: Contact your Internet Service Provider (ISP) to upgrade your bandwidth if you are experiencing bandwidth constraints.

  4. Resource Investigation: Investigate the reason for missing resources and high CPU usage on your device. This may be due to a software issue, firmware update requirement, buggy software update, or simply inadequate resources, which can be resolved by upgrading to a more powerful device.

C. Check for Internet Problems on Your ISP’s End
C. Check for Internet Problems on Your ISP’s End

If you don’t see any resource issues from your devices, this is a sign that the network problem is actually on your Service Provider’s end.

If you suspect that the issue is with your ISP, you should open a service ticket and provide as much information as possible to support your claim. This will help to quickly escalate the issue past the first level of support. Additionally, Obkio's app can serve as a valuable tool to aid in this process.

The data you can provide is that from your dashboard in the previous steps, as well as your Traceroutes in the next step.

Network Troubleshooting Step 5. Troubleshoot using Traceroutes
Network Troubleshooting Step 5. Troubleshoot using Traceroutes

The next step in the network troubleshooting process is to collect the last bit of data to help you pinpoint exactly where the network problem is located so you can share that information with your Service Provider.

To do this, we’ll be using Obkio Vision, Obkio’s free Visual Traceroute tool that runs continuously to interpret Traceroute results to identify network problems in your WAN and over the Internet.

Note: If the network problem happening only on your end, you don’t need to do this step. It’ll just give you the same results.

Use Traceroutes, the Network Map, and the Quality Matrix to identify if:

A. The network issue is happening specifically towards a specific location over the Internet. So only one specific site is being affected.

network troubleshooting traceroutes Obkio Vision Network Map

B. The network issue is on your ISP’s side. At this point, open a service ticket with as much information as you can collect.

Network Troubleshooting Step 6. Contact Your Service Provider
Network Troubleshooting Step 6. Contact Your Service Provider

If you encounter an issue, it is recommended to contact your Service Provider (MSP or ISP) for assistance with troubleshooting. However, this time, you won't have to deal with first-level support simply instructing you to "reboot your modem." Armed with the data collected using Obkio, you can hold your Service Provider accountable and provide them with all the necessary information to effectively troubleshoot the issue.

  1. Contact your ISP to get technical support using the screenshots of Monitoring Sessions, Dashboards or Traceroutes in Vision.
  2. Share results of Live Traceroutes with your ISP using a public link.
  3. If your ISP wants to analyze your data further, you can create a temporary Read-Only User in your Obkio account for them.

By sharing traceroute results, ISP network engineers can see the problem, change the traceroute options and validate that their changes are fixing the issue without having to get back to you.

Your ISP will then be able to confirm if your analysis is good or not, and if they can fix the issue at hand. If you have the chance to have a good ISP, they will also explain why your analysis is wrong if this is the case.

Network Troubleshooting Step 7. Perform a DNS Check
Network Troubleshooting Step 7. Perform a DNS Check

At this point, if you're still ensure of the cause of the issue, one last thing you can do it perform a DNS check.

DNS, which stands for Domain Name System, is a directory for the Internet (and every internet-connected device) that matches domain names with IP addresses. Every single website has its own IP address on the web, and computers can connect to other computers via the Internet and look up websites using their IP address.

Use the “nslookup” command to determine whether there’s a problem with the server you’re trying to connect to. If you perform a DNS check on, for example, google.com and receive results such as “Timed Out,” “Server Failure,” “Refused,” “No Response from Server,” or “Network Is Unreachable,” it may indicate the problem originates in the DNS server for your destination. (You can also use nslookup to check your own DNS server.)

With Obkio’s Application Performance Monitoring (APM) for HTTP URLs feature, users can now monitor DNS performance! DNS is key to URL monitoring, and is one of the five steps to download the content of a single URL.

Network Troubleshooting Step 8. Continue to Monitor Network Performance
Network Troubleshooting Step 8. Continue to Monitor Network Performance

Continuing to monitor network performance is a crucial step in network troubleshooting. After implementing a fix, it's essential to ensure that the network is operating optimally and that the issue is resolved.

Here's why continuing to monitor network performance is important:

  • Verify that the issue is resolved: Continuing to monitor the network performance can help you ensure that the issue is resolved. If the issue persists, you may need to investigate further and implement additional fixes.
  • Identify new issues: Even if the original issue is resolved, new issues may arise. Continuously monitoring the network performance can help you identify any new issues and address them proactively.
  • Optimize network performance: Monitoring the network performance can help you identify areas of the network that can be optimized for better performance. For example, you may find that some devices or applications are using an excessive amount of bandwidth, causing performance issues for other devices on the network.
  • Ensure network security: Monitoring the network performance can help you identify potential security threats and breaches. You can set up alerts to notify you of any suspicious network activity and take action to prevent security breaches.

In summary, continuing to monitor network performance after troubleshooting helps you ensure that the network is operating optimally and proactively address any new issues that may arise.
