Microsoft IIS
Supported versions
IIS monitor allows monitoring all versions of Microsoft IIS (Internet Information Services).
Definition
The available performance objects are:
- Internet Information Services Global
- Web Service
- Web Service Cache
- HTTP Indexing Service
As the monitor uses the same technology as the Perfmon monitoring tool included with Windows, NeoLoad is able to access all the counters available for IIS.
Microsoft monitors use a Windows API to list and query performance counters, namely the Performance Data Helper (PDH) library used by Perfmon which is a Windows tool. Therefore, the NeoLoad Microsoft monitors have the same characteristics and constraints as Perfmon:
- Monitoring is done without installing any additional component, which obviates the installation of a specific client on the machine to be monitored.
- The monitoring of Microsoft servers is only possible using Windows monitoring agents. Microsoft servers cannot be monitored with a Unix/Linux monitoring agent.
- The account used to start the monitoring agent (or NeoLoad for the built-in agent) must have the appropriate user rights. See Connect to a remote server.
When defining a counter, and depending on the type of counter, one or more instances may be also selected. One instance corresponds to a certain sub-division of the monitored object. For example, Processor/Processor Time % has several instances, one for each processor present in the monitored machine. Usually, an instance named _Total allows retrieving an average value across all available instances.
Create an IIS monitor
NeoLoad makes it possible to create a new monitor either using the monitored machine creation wizard, as described in Create and configure a monitored machine, or from an existing monitored machine, as described in Create and configure a monitor.
