Retrieving Top-N Analysis Data

To identify the best/worst players in a particular performance area, administrators need to rank components/descriptors for every metric collected by the eG Enterprise. For such ranking, administrators need to figure out the Top-N Analysis data offered by eG Enterprise. Using the eG REST API, administrators can figure out the Top-N data of the components/descriptors of a measure reported by eG Enterprise without logging into the eG console. The table below specifies the parameters that should be used to retrieve the health of the infrastructure.

URL: http://<eG manager IP:port>/api/eg/analytics/getTopNData

Method: POST

Content-Type: application/json

Inputs to be Specified
Parameters Key values Example


managerurl: Base URL of the eG Manager i.e., http://<IP address of the eG console:Port>

user: eG username or domain/eG username

pwd: Base64 encoded password

"componentName": "TEZ-MSSQL-DB:1433",

"componentType": "Microsoft SQL",

"test": "SQL Errors",

"measure": "Error rate",

"info": "Info Errors"





"timeline":"Timeline for retrieving the measure data (in hours/days/weeks)",

"componentName":"Hostname of the component:Port/Null",

"componentType":"Component Type",

"test":"Test name",

"measure":"Measure name",

Retrieving Top-N Analysis Data using cURL

To retrieve the Top-N Data of components/descriptors using cURL, the command should be specified in the following format:

curl -L -X POST "http://<eG Manager IP:Port>/api/eg/analytics/getTopNData" -H "user:<eG username or domain/eG username>" -H "pwd:Base64 encoded password" -H "managerurl:http://<eG Manager IP:Port>" -H "Content-Type:application/json" --data-raw "{\"timeline\":\"Timeline for retrieving the Top-N data (in hours/days/weeks)\",\"componentType\":\"Component Type\",\"componentName\":\"Component name:Port\",\"test\":\"Test name\",\"measure\":\"Measure name\",\"info\":\"Descriptor name\"}"

Figure 2 shows an example of retrieving the Top-N Analysis Data using cURL.
