_caching_policy

Section: urs-stat
Default Value: 5
Valid Values: Integer
Changes Take Effect: Immediately

This option is mandatory.

URS Statistic caching policy in seconds.

_urs_stat_url_parameters

Section: urs-stat
Default Value: No default value
Valid Values: String
Changes Take Effect: Immediately

This option is mandatory.

Additional URS lvq input parameters (url-encoded format). For example: name=<VQ_Name>&tenant=<Tenant_Name>&aqt=urs

_urs_url

Section: urs-stat
Default Value: No default value
Valid Values: URL
Changes Take Effect: Immediately

This option is mandatory.

The URS URL formatted as follows: http://<urshost>:<ursport>/urs/call/max/lvq. This option can also point to the load balancer in front of the URS.

Urs-stat

Type: builtin
Updated in: 8.5.109

Create a GMS built-in service using the urs-stat template that provides the following benefits:

  • Statistics caching of the statistic to reduce load on URS. The _caching_policy parameter sets the cache period in seconds (see below).
  • Load balancing and scaling across multiple GMS nodes.
  • A single point of contact for your app.

Create a urs-stat Service

To create this GMS built-in service, select the urs-stat template when creating a new service. GMS-CreateURSStat.png

Configure urs-stat parameters

Configure the following parameters in your <name-of-urs-stat-service> service:

Option Description
_urs_url The URS URL formatted as follows: http://<urshost>:<ursport>/urs/call/max/lvq. This option can also point to the load balancer in front of the URS.

_urs_stat_url_parameters Additional URS lvq input parameters (url-encoded format). For example: name=<VQ_Name>&tenant=<Tenant_Name>&aqt=urs

_caching_policy URS Statistic caching policy in seconds.

For example:

_caching_policy=30 # Cache refresh time in seconds
_service=urs-stat
_type=builtin
_urs_stat_url_parameters=name=<VQ_Name>&tenant=<Tenant_Name>&aqt=urs
_urs_url=http://<urshost>:<ursport>/urs/call/max/lvq

Where: VQ_Name, Tenant_Name, urshost, and ursport match the environment and Callback service's Virtual Queue (VQ). The following screenshot shows the creation and configuration of the my-urs-stat service.

Important
The _urs_url option can point to the load balancer in front of the URS that should be configured as part of the GMS provisioning steps in that scenario.

Query EWT Using the urs-stat Service

The following query example shows the resulting response that you get when you call the service:

GET http://<gmshost>:<gmsport>/genesys/1/service/<name-of-urs-stat-service>
 
Response:
{ "wcalls" : 20, "wpos" : 21, "time" : 1467922222, "hit" : 95, "calls" : 20,
 "wt" : 0, "ewt" : 300, "pos" : 21, "aqt" : 300 }
Important
  • The value of interest here is ewt: the time unit is seconds and can be a float value.
  • An empty object will be returned if there is no activity for the VQ.

You can use a single service for multiple VQs by omitting the _urs_stat_url_parameters option from the service and including the value for that option (for example, name of virtual queue, tenant ID, or statistical method) in the HTTP request as follows:

http://<gmshost>:<gmsport>/genesys/1/service/<name-of-urs-stat-service>
?name=<one-of-the-callback-VQs>&tenant=<tenant-name>&aqt=urs

The URS stat service will append the content of the _urs_stat_url_parameters option and the HTTP request parameters to the URS query. To view additional URS lvq input parameters and output information, open a browser with URS running and run the help method for lvq as follows:

http://<urshost>:<ursport>/urs/help/call/lvq

The help method is described in the Universal Routing 8.1 Reference Manual, Appendix C, "Supported Methods."

If, for example, you set the following configuration for the <name-of-urs-stat-service> service:

_caching_policy=5
_service=urs-stat
_type=builtin
_urs_stat_url_parameters=scale=true&tenant=Environment&aqt=urs
_urs_url=http://<ursloadbalancer>:<ursport>/urs/call/max/lvq

You can can use this service for multiple VQs by specifying only the name of a virtual queue in the HTTP request as follows:

http://<gmshost>:<gmsport>/genesys/1/service/<name-of-urs-stat-service>
?name=<one-of-the-callback-VQs>
