    Table 1. REST Transport Metrics
    Metric Metric type Description
    Access Time - The date and time at which the metrics have been retrieved
    Average AppServer time Time The average time spent in returning a response from the AppServer to the REST transport
    Average connect time Time The average time spent in using the REST transport to connect to the AppServer
    Average transport time Time The average of the times spent in making a request to the AppServer via the REST transport and in returning a response from the AppServer by the REST transport
    Connect requests Count The number of requests for which new connections have been made between the REST transport and AppServer
    Expression errors Count The number of requests in which a parameter value has incorrectly formatted JSON data
    Failed requests Count The number of requests that have resulted in a failure error message
    Last reset time - If you click Reset, this field displays the date and time at which you have reset the metrics for the service. When the metrics are reset, the Last Reset Time field is updated.
    Maximum AppServer time Time The maximum time spent in returning a response from the AppServer to the REST transport
    Maximum connect time Time The maximum time spent in using the REST transport to connect to the AppServer
    Maximum transport time Time The maximum value of the times spent in making a request to the AppServer via the REST transport and in returning a response from the AppServer by the REST transport
    Minimum AppServer time Time The minimum time spent in returning a response from the AppServer to the REST transport
    Minimum connect time Time The minimum time spent by the REST transport to connect to the AppServer
    Minimum transport time Time The minimum value of the times spent in making a request to the AppServer via the REST transport and in returning a response from the AppServer by the REST transport
    Requests Count The total number of requests (successful or failed) made to the REST transport for access to the AppServer
    Run requests Count The number of requests for which an ABL class, function, or procedure has been invoked on the AppServer
    Service not found Count The number of requests for which a REST service has not been found
    Service unavailable requests Count The number of requests made during which the REST transport is disabled
    Standard deviation AppServer time Time The standard deviation of the time spent in returning a response from the AppServer to the REST transport
    Standard deviation connect time Time The standard deviation of the time spent by the REST transport to connect to the AppServer
    Standard deviation transport time Time The standard deviation of the times spent in making a request to the AppServer via the REST transport and in returning a response from the AppServer by the REST transport
    Status requests Count The number of requests made for the status of the REST transport
    Successful connect requests Count The number of requests for which connection objects have been successfully created. These objects are used to run a service on the AppServer.
    Successful requests Count The number of requests for which the AppServer has sent a successful response
    Successful run requests Count The number of requests for which an ABL class, function, or procedure has been executed successfully on the AppServer and a response is sent to the REST transport
    Type - The transport for which the metrics are collected
    Note: If the collectMetrics property is not set in the openedge.properties file, only the Access Time, Last Reset Time, and Type metrics are collected.

    You can reset the time and count values of REST transport metrics to zero by clicking Reset statistics. The Last Reset Time field is updated when the statistics are reset.

    Additionally, you can see PAS REST WebApp Requests Rate graph that displays the request data over time. Using the options on the top-right corner of the graph, you can select a time period, ranging from 2 hours to 2 weeks, to display the data collected for that period of time, reload the graph, and select different forms of graphical interpretation.
