~ The time-taken column shows the numbers in milliseconds.
Please note that all the results, lines, graphs and panels are completely clickable and enable further drill down into the root cause analysis of a specific item presented.
A quick glance at the XpoLog access logsInsight section (in the left sidebar), tells you that XpoLog automatically found some HTTP errors, although you did not specifically ask XpoLog to look for them.
XpoLog is indicating HTTP error codes it has found that obviously causing your web page to malfunction.
In order to analyze there root cause you may want to have a closer look and see how many times an HTTP status code occurred.
In order to do that, copy & paste the following query:
Notice the table row below the graph has a plus-sign on the right. If you hover over it, you will get two view options, Log Viewer and Analytics.
In the Log Viewer, you can view each individual log in detail. You can open a new tab for each log and view many logs, each individually down to the smallest detail, and then toggle through the tabs to compare them.
Here is what one of the logs containing a 404 error looks like (scrolled to the middle):
If you choose to view the log in Analytics, XpoLog Access Logs Performance Analyzer will show you all the errors in this log, 404 and any others:
and the result will bring you back to the XpoLog Search interface:
Another awesome XpoLog Access Logs Performance Analyzer feature you can see in the above screen capture is the drill down box explicitly presenting the number of specific errors found within each moment in time. This box will appear any time you hover over a graph in the Search interface. It is essentially like the XpoLog Analytics Insight section in the left sidebar, but specific per time-instance.
From the aforementioned example, we learn that the reason the performance slowed down was not the weight of the page, but rather the HTTP errors – resources not found, internal server errors and not supported/implemented (server does not recognize the request method and is not capable of supporting it for any resource).
XpoLog Access Logs Performance Analyzer GEO IP
Now that we have analyzed the root cause of the website performance, we view and analyze the locations of the visitors with the access logs.
Using XpoLog Access Logs Performance Analyzer a view of all visitors geographic like location and IP is done intuitively.
