Monitor Type: aspdotnet (Source)

Accepts Endpoints: No

Multiple Instances Allowed: No

Overview

(Windows Only) This monitor reports metrics about requests, errors, sessions, worker processes for ASP.NET applications.

Windows Performance Counters

The underlying source for these metrics are Windows Performance Counters. Most of the performance counters that we query in this monitor are actually Gauges that represent rates per second and percentages.

This monitor reports the instantaneous values for these Windows Performance Counters. This means that in between a collection interval, spikes could occur on the Performance Counters. The best way to mitigate this limitation is to increase the reporting interval on this monitor to collect more frequently.

Sample YAML configuration:

monitors:
 - type: aspdotnet

Configuration

To activate this monitor in the Smart Agent, add the following to your agent config:

monitors:  # All monitor config goes under this key
 - type: aspdotnet
   ...  # Additional config

For a list of monitor options that are common to all monitors, see Common Configuration.

Config option Required Type Description
counterRefreshInterval no int64 (Windows Only) Number of seconds that wildcards in counter paths should be expanded and how often to refresh counters from configuration. (default: 60s)
printValid no bool (Windows Only) Print out the configurations that match available performance counters. This is used for debugging. (default: false)
