You use IIS monitors to check metrics of your IIS servers.
Requirements
To monitor an IIS server, you need to prepare it in the same way you prepare Windows servers for testing:
-
ReadyAPI must run on a Windows machine. Windows, IIS and MSSQL monitors are not available on Linux and macOS machines.
-
The Remote Registry service must be enabled on the server.
-
Ports 139 and 445 must be open on the server, the computer with ReadyAPI and any proxy between them.
-
The user account must have Performance Monitor or Administrator permissions on the server.
For detailed information, see Preparing Servers for Monitoring.
Monitor Settings
The monitor does not have settings.
Frequently Used Metrics
The IIS monitor provides information about user interaction with the server. ReadyAPI displays the following statistics in charts by default:
-
Web Service – Current Connections – Total – The current number of connections to the server. This value should be the same as the number of virtual users you simulate.
-
Web Service Cache – Kernel – URI Cache Hits – The number of hits to the cached URIs. It is generally preferred to have this value as high as possible. However, if your server cannot store the response cache, this value should be low.
Here are some other frequently used metrics:
-
Web Service – Service Uptime – Measures the period of time during which the server has been running. Most servers need to be regularly rebooted for installation of updates and for maintenance. A server with long uptime may cause performance issues.
-
Web Service – Locked Errors/sec – Measures the number of requests which failed because the requested resources were already in use. The resources may be in use, or "locked" if the previous request did not free them up before the server tried to handle the next request in the queue.
-
Web Service Cache – Current File Cache Memory Usage – Measures the amount of memory used by the web service cache. The files are cached to increase the speed of access, but, if there is not enough memory in your server, this may cause performance issues.
Other Metrics
ReadyAPI can access the Web Service and Web Service Cache PerfMon objects and their respective counters. You can find a full reference to IIS 6.0 counters on the Microsoft web site. The following statistics are usually available:
