Configuring the HttpClient Monitoring Item

On the Modify HttpClient Monitoring Configuration page, set the following URL normalization parameters:

  • Collection Interval: The default value is 60s and cannot be changed.
  • URL normalization is used to aggregate URLs that meet the conditions you set. For example, http://localhost/rest/v1/test/123 and http://localhost/rest/v1/test/234 can be aggregated into http://localhost/rest/v1/test/{id}.

Normalization Methods

There are four normalization methods: startwith, endwith, include, and regex.

  • startwith: URLs starting with a certain expression are counted as normalized URLs. For example, URLs starting with http://127.0.0.1/v1 are aggregated into /v1/test/{id}, as shown in Figure 1.
  • endwith: URLs ending with a certain expression are counted as normalized URLs. For example, URLs ending with /test are aggregated into /{id}/test, as shown in Figure 1.
  • include: URLs containing a certain expression are counted as normalized URLs. For example, URLs containing test are aggregated into /test/{id}, as shown in Figure 1.
  • regex: URLs that meet the wildcard expression are counted as normalized URLs. For details about the wildcard rules, see Table 1.
