Performance SLA Calculation using AppDynamics REST API | Individual Business Transaction | PowerShell

Sahil_Gupta — Tue, 19 Jan 2021 10:53:05 GMT

Hi Experts,

I have created a PowerShell Tool to generate Daily Performance SLA Calculation for Individual Business Transactions using AppDynamics REST API. I tried my best to add explanation of each code line.

Hope it is helpful!

##It is PowerShell Code, marked it as Python to keep the indent as is##

#Prerequisites: # 0) Make Sure you have basic understanding of PoswerShell and AppD REST API - It is no rocket science
                # 1) PowerShell, MicroSoft Excel (I tested it with Excel 2013)

#Instructions: # 0) This tool automatically takes care of EPOCH time calculations. Calcumations are done in 
             # 1) Make sure user name is followed by '@customer1' or relevent customer ID
             # 2) It uses H:\ as default drive to save output excel, you can change it if required
             # 3) This reprot is created to support 4 Business Transactiosn, using same user ID for authantication
             # 4) Instructions to modify users is mentioned in script
             # 5) If you need to add / remove BTs, please understand this script and do it manually
             # 6) #This report works in UTC - Coordinated Universal Tim
             # 7) Formula Used: Percentage Successful transactions = ((Sum of Call - Sum of Errors )/ Sum of Calls) *100

#Clear Variable Cache (Without popping up erros on PowerShell Screen) - Start 
Remove-Variable * -ErrorAction:Ignore
#Clear Variable Cache - Completed

 
#Custom Message (Optional) - Start

hello Sahil,

first of all thanks for the code.

I got some errors when I wanted to use it. I wanted to change the url here. I wrote application id instead of "SUM-Calls-PER-MIN-ENDPOINT", but I still couldn't run it.

Also, how can I see the response results for a single url?

When I say $response it is empty.

I request your help.

$controllerEndpoint = "controller/rest/applications/SUM-Calls-PER-MIN-ENDPOINT/&time-range-type=BETWEEN_TIMES&start-time=$StartDateEpoch&end-time=$EndDateEpoch"
PS D:\Users\halerol> $restURL = "${protocol}://${controller}:${port}/${controllerEndpoint}"
PS D:\Users\halerol> $restURL
https://appd:443/controller/rest/applications/SUM-Calls-PER-MIN-ENDPOINT/&time-range-type=BETWEEN_TIMES&start-time=&end-time=
PS D:\Users\xxx> $headers = @{Authorization = 'Basic ' + [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("${user}:${password}"))}

PS D:\Users\xxx> $headers = @{Authorization = 'Basic ' + [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("${user}:${password}"))}

Hello @Haluk Yaşar.Erol,

I am the same Sahil, with just a new ID 😄

Thank you for your question. Here are a few things I can suggest:

#The script shared above works ONLY with Windows PowerShell. I used it so most of us can run it from our local desktop without any additional software.

1) Always copy the URL from Metric Browser. Check, screenshot1 attached

2) SUM-Calls-PER-MIN-ENDPOINT is NOT a valid API to call. We call the Calls%20per%20Minute API, the output of which gives us SUM/Count/current/Max/Min.

https://docs.appdynamics.com/21.7/en/extend-appdynamics/appdynamics-apis/metric-and-snapshot-api#MetricandSnapshotAPI-FullExample:.2

I will suggest you first try the basic AppDynamics APIs with PowerShell.

A good place to start? https://community.appdynamics.com/t5/Knowledge-Base/How-do-I-use-REST-API-calls-in-a-PowerShell-script/ta-p/37193

Additional Info: How to change time in AppD REST API?

More about AppD Metric REST API?

https://docs.appdynamics.com/21.7/en/extend-appdynamics/appdynamics-apis/metric-and-snapshot-api

Hope this helps!

Hello Sahil,

Thanks for your reply.
I will look into the links you shared.

How can we get the results by putting certain filters in X application.

Sample ;
in app X
Critical Category
Service in 7x24 period
Number of Calls > 10 and Response Time > 3s
Minor Category

Service in 7x24 period
Number of Calls > 10 to 1s 3s
Number of Calls > 1 and Response Time > 5s
Warning Category

Service in 7x24 period
1 < Number of Calls < Between 10 and 1s < 5s

How can I get the data in the categories here with api or powershell?

I do this with filters over standard appdynamics manually every month. I want to do it with script or with api, but I don't know much about these issues. If you have a chance to try, I would like you to share examples.

Hello @Haluk Yaşar.Erol ,

I would suggest you to use Dexter.

https://developer.cisco.com/codeexchange/github/repo/Appdynamics/AppDynamics.DEXTER

Creating a script from scratch is hell lot of a task and time-consuming.

#Not sure if I understood your request correctly, though if your goal includes to report how many Number/SUM-of-transactions in last 1 MONTH had response time > 3sec(or whatever), I think this is not archivable. AppD rolls up the data captured at 1 minute average. There is NO record for response time of individual transactions (except snapshot).

Metric Data Resolution over Time?
