Troubleshooting Latencies from One Monitoring Location

There are several methods for identifying a latency problem in a particular monitoring location. Log in to your AlertSite Console and try these strategies:

  • Run a Technical Benchmark Report in order to compare your site with either more of your own sites or other high profile sites on the Internet:
    • Go to Reports–>Performance Reports
    • Choose the site or transaction in question from the dropdown
    • Under Select, leave the radio button checked for Detail
    • Under Include, check the box next to Technical Benchmarks
      Note: Select Report Details only if you are running a report for 24 hours or less or have long monitoring intervals (> 15 minutes),
      otherwise the report could be truncated if it's more than 2500 rows
    • Select the Monitoring Location in question
    • Select the desired Date Range
    • In the Technical Benchmarks section (top right), choose your device
    • In the Compare to your other monitored site(s) box, choose up to 7 additional sites to compare with your selected site
    • Click Create Report.

  • Run a Traceroute from that particular monitoring location:
    • Go to Support–>Site Diagnostics
    • Select a Site from the Test Your Site dropdown
      Note: You cannot run a traceroute to a DejaURL or DejaClick Transaction. If you are not monitoring any sites, click the radio button
      next to Test Other Site and enter any website address, e.g., www.google.com; the Type should be Web Site.
    • From the Test Type dropdown, select TCP Traceroute
    • Choose the Location in question
    • Enter an email address where you want to receive the traceroute output
    • Click Submit in the upper right
    • Check your email for the traceroute output

  • Run a Test On Demand for your DejaURL or DejaClick Transaction from Site Diagnostics:
    • Go to Support–>Site Diagnostics
    • Select a DejaURL or DejaClick Transaction from the Test Your Site dropdown
    • From the Test Type dropdown, select Test On Demand
    • Choose the Location in question
    • Click Submit in the upper right
    • The Test On Demand screen will appear and run your test
    • Examine the Detail Report (link at the bottom center) and Fullpage Report (blue and green horizontal bar chart in the thumbnail) that result

  • Analyze your site's Diagnostic Details to see what IP numbers you are directed to and if there are any errors you may not be aware of:
    • Go to Reports–>Performance Reports
    • Choose the site or transaction in question from the dropdown
    • Run a Detail Report and include Report Details
    • Select the Monitoring Location in question
    • Select the desired Date Range
      It is recommended to use a short time period, say, an hour before and after the problem time frame, when including Report Details
    • View the HTML- formatted report and select one of the measurements that is showing latency
    • Click on the Diagnostics Icon (small multicolor bar chart) in the left column of the measurement line
    • Analyze the report for the IP numbers we are resolving to as well as any returned error information from your server.
