Web Server Monitoring provides information about the availability and performance of web servers, such as Apache, Microsoft Internet Information Services (IIS), IBM HTTP Server, and the Oracle HTTP Server web server. Using the Web Server Monitoring, web server administrators can detect and resolve web server availability and performance problems.
Install the Web Server Monitoring on any host behind a firewall. Configure the monitored web servers to publish the performance statistics to a URL on that web server. The Web Server Monitoring periodically connects remotely using HTTP or HTTPS to the web server, collects the statistics, and reports the statistics to Introscope. Configure the Web Server Monitoring to discover and monitor any new web server that appears on the specified subnet or subnets.
Only applications that are monitored by Java agents are correlated with web server nodes in CA APM Team Center.
To assist web server administrators to find and fix problems, the Web Server Monitoring provides the following information:
  • Alerts that indicate the availability of each web server.
  • Performance statistics that track the web server load, throughput, cache usage, and the number of threads or processes that are idle or in use.
  • Details about the time you spend on various tasks for each web server.
  • Predefined dashboards that enable quick diagnosis of the most common web server issues.
  • Web server node that appear as a component on the APM Map. Calls to and from the Web server that originate from or are going to other monitored applications are correlated with the Web server.
The Web Server Monitoring provides the following capabilities:
  • Minimal Setup
    • Auto-discovery finds all web servers on your network
    • Auto-configuration tunes Web Server Monitoring settings for each individual web server
    • Agentless design that eliminates the need to install anything on each web server.
  • Dynamic Reconfiguration
    • Auto-discovery detects changes to web servers and adjust web server monitoring settings without user intervention.
  • Improved Web Server Support
    The following web servers are supported:
    • Customized and new versions of the Apache web server
    • Apache-based web servers
    • New releases of Microsoft IIS
Troubleshooting
Issue 1
Symptom
I am not able to view the Web Server metrics.
Solution
Each webserver exposes URL to APM for gathering performance metrics. Ensure Web Server infrastructure agent is able to access the Web Server.
Issue 2
Symptom
ATC map is not visible
Solution
Make sure x-Forwarded-For and x-Forwarded-Host headers are enabled and transactions are going through Web Server.
