Create custom resource to show "Who is On Call" via OpsGenie API

Question

I'm setting up an OpsGenie trial right now, with SolarWinds Orion integration for on-call management. The feature set looks pretty sweet after having managed scheduling, rotation, and weekly changes manually!

Question: I'm curious if there is a way to create a custom resource on an Orion page that shows the current on-call person[s] via OpsGenie's API.

Continuing this quest, I spoke with a developer colleague and he determined that api.opsgenie.com doesn't allow CORS requests (Cross-Origin Resource Sharing). In his words, "Basically, for security reasons the browser prevents javascript code from making requests to a domain that is different than the origin from which it was served, unless the requested resource returns the proper headers. When a CORS request is made, the browser sends a “pre-flight” check – an OPTIONS request to the server. If the server responds with the proper access control header(s), the “real” request is sent, otherwise it’s a no-go. I’m not sure what the simplest way around this is. You’d either need a proxy server to return the proper CORS headers to allow the browser to make the api call or a local endpoint (ie, one that we control) that would make the call and return the results to the browser client." - Developer Colleague Already being beyond my pay grade, I decided to return to what I know: PowerShell and Orion application templates. The process began with creating a new node in Orion for "app.opsgenie.com" and configuring it to monitor status only (ICMP). For extra measure, I also populated the URL field with https://app.opsgenie.com farther down in the properties page. Node Application Template The next step was to create a template to poll OpsGenie. This template uses a Windows PowerShell Monitor to poll OpsGenie and pull the on-call information into Orion! As an aside, I also used this template to send an API heartbeat to OpsGenie. The OpsGenie service can be configured to alert the team if a heartbeat is not received. This is a good way to tell if your internal infrastructure might have a problem that is preventing alerts from getting posted to OpsGenie. After receiving the heartbeat 'PING', OpsGenie then sends a 'PONG' response back to the PowerShell script in Orion. Working both ways now, if Orion does not receive the 'PONG' response, it will alert that OpsGenie is non-functional. Anyway, the details of this will be a separate post, I think! The script below is what I used to pull all IT teams' on-call schedules. It can be simplified to pull specific teams if necessary, but in this case we wanted all of the IT teams presented. $key = "REDACTED" #OpsGenie Default Integration API Key $header = @{'Authorization' = 'GenieKey ' + $key} #Authentication is required with every OpsGenie API request. $OnCall = @{} #Create a hash table to store team names and on call names. $allSchedules = (Invoke-RestMethod -Method GET -Uri " ">api.opsgenie.com/.../" -Headers $header).Data #Get the deta for all on call schedules. foreach ($schedule in $allSchedules) #Loop through each on call schedule to get the team name and the on call person's name. { $thisScheduleID = $schedule.ID $uriEach = " ">api.opsgenie.com/.../on-calls" $OnCall.Add( (Invoke-RestMethod -Method GET -Uri $uriEach -Headers $header).data._parent.name, ` (Invoke-RestMethod -Method GET -Uri $uriEach -Headers $header).Data.onCallParticipants.Name ) } #End foreach schedule $OnCall.GetEnumerator() | ForEach-Object { $StatLabel = $_.Key.ToString().Replace(' ','')+":" #Write the statistic label as the team name without spaces, followed by a colon. $StatOutput=$StatLabel + " " + $_.Value #Create the stat output string with the label and a numeric value. #Format the output for Orion. The message can be a string, but the statistic must be a number, so the hash table item indecies are passed. Write-Host "Message.$StatOutput" Write-Host "Statistic.$StatLabel" $($OnCall.Keys).IndexOf($_.Key) } The resulting preview output shows: A message with the team name and that team's person on call. A statistic with the index of the item (team) in the $OnCall hash table. (Because it seems Orion will only accept an integer as the returned stat.) Back in the application template, we now have 4 script output values, with one example shown here: It feels like we're close! Now I'm just looking for a way to capture the script output message[s] into an alert or a custom property that can then be queried on a page in a custom view. This last piece would fulfill the original goal.
