New user of the BAM with CEP integration, I'm currently following the "Monitoring Realtime Traffic" sample from WSo2 Doc and block when creating the Execution-plan step. Link to doc
The doc requires to
4. Under Import Stream select org.wso2.sample.rt.traffic for Import Stream, and enter traffic for As.
Unfortunatly when I click "import" nothing happens (in the doc it shows we should get //imported from org.wso2.sample.rt.traffic:1.0.0)
When I try to add the execution plan I get the "Imported streams cannot be empty"
Am I making a mistake ?
Regards
Vpl
I was able to solve the issue of this UI problem by creating the event stream directly into the registry table. For that I've created the following resource
/_system/governance/StreamDefinitions/org.wso2.sample.rt.traffic/1.0.0
containing
{
"streamId": "org.wso2.sample.rt.traffic:1.0.0",
"name": "org.wso2.sample.rt.traffic",
"version": "1.0.0",
"payloadData": [
{
"name": "entry",
"type": "STRING"
}
]
}
With a Media Type: application/json
Then creating the execution plan I could import the event stream and continue the use-case/ / tutorial

We need a way to access data through an automated way (either Rest API or some SDK) that is contained within the Retrospective Azure Dev Ops extension. Currently, there is an option to export CSV but the process is manual and limited to each Retrospective. Any ideas/thoughts?
You can try like as the following steps:
Run the API to get the information of project teams in a project.
Request URL
POST https://dev.azure.com/{organization_Name}/_apis/Contribution/HierarchyQuery?api-version=5.0-preview.1
Request Body
{
"contributionIds": ["ms.vss-admin-web.org-admin-groups-data-provider"],
"dataProviderContext": {
"properties": {
"teamsFlag": true,
"sourcePage": {
"url": "https://dev.azure.com/{organization_Name}/{project_Name}/_settings/teams",
"routeId": "ms.vss-admin-web.project-admin-hub-route",
"routeValues": {
"project": "{project_Name}",
"adminPivot": "teams",
"controller": "ContributedPage",
"action": "Execute",
"serviceHost": "{organization_Id} ({organization_Name})"
}
}
}
}
}
Run the API to list the retrospectives for a specified project team in the project.
GET https://extmgmt.dev.azure.com/{organization_Name}/_apis/ExtensionManagement/InstalledExtensions/ms-devlabs/team-retrospectives/Data/Scopes/Default/Current/Collections/{projectTeam_identityId}/Documents?api-version=3.1-preview.1
Run the API to get more details about a specified retrospective.
GET https://extmgmt.dev.azure.com/{organization_Name}/_apis/ExtensionManagement/InstalledExtensions/ms-devlabs/team-retrospectives/Data/Scopes/Default/Current/Collections/{retrospective_Id}?api-version=3.1-preview.1
However, we have not any available interface (API or CLI) to Export CSV content.
I'm using the docker image of Keycloak 10.0.2. I want Keycloak to supply access_tokens that can be used by Hasura. Hasura requires custom claims like this:
{
"sub": "1234567890",
"name": "John Doe",
"admin": true,
"iat": 1516239022,
"https://hasura.io/jwt/claims": {
"x-hasura-allowed-roles": ["editor","user", "mod"],
"x-hasura-default-role": "user",
"x-hasura-user-id": "1234567890",
"x-hasura-org-id": "123",
"x-hasura-custom": "custom-value"
}
}
Following the documentation, and using a script I found online, (See this gist) I created a Script Mapper jar with this script (copied verbatim from the gist), in hasura-mapper.js:
var roles = [];
for each (var role in user.getRoleMappings()) roles.push(role.getName());
token.setOtherClaims("https://hasura.io/jwt/claims", {
"x-hasura-user-id": user.getId(),
"x-hasura-allowed-roles": Java.to(roles, "java.lang.String[]"),
"x-hasura-default-role": "user",
});
and the following keycloak-scripts.json in META-INF/:
{
"mappers": [
{
"name": "Hasura",
"fileName": "hasura-mapper.js",
"description": "Create Hasura Namespaces and roles"
}
]
}
Keycloak debug log indicates it found the jar, and successfully deployed it.
But what's the next step? I can't find the deployed mapper anywhere in the GUI, so how do I activate it? I tried creating a protocol Mapper, but the option 'Script Mapper' is not available. And Scopes -> Evaluate generates a standard access token.
How do I activate my deployed protocol mapper?
Of course after you put up a question on SO you still keep searching, and I finally found the answer in this JIRA issue. The scripts feature has been a preview feature since (I think) version 8.
So when starting Keycloak you need to provide:
-Dkeycloak.profile.feature.scripts=enabled
and after that your Script Mapper will show up in the Mapper Type dropdown on the Create Mapper screen, and everything works.
I am trying to integrate Azure App insights service into the service fabric app for logging and instrumentation. I am running fabric code on my local VM. I exactly followed the document here [scenario 2]. Other resources on learn.microsoft.com also seem to indicate the same steps. [ex: https://learn.microsoft.com/en-us/azure/service-fabric/service-fabric-diagnostics-event-aggregation-eventflow
For some reason, I don’t see any event entries in App insights. No errors in code when I do this:
ServiceEventSource.Current.ProcessedCountMetric("synced",sw.ElapsedMilliseconds, crc.DataTable.Rows.Count);
eventflowconfig.json contents
{
"inputs": [
{
"type": "EventSource",
"sources": [
{ "providerName": "Microsoft-ServiceFabric-Services" },
{ "providerName": "Microsoft-ServiceFabric-Actors" },
{ "providerName": "mystatefulservice" }
]
}
],
"filters": [
{
"type": "drop",
"include": "Level == Verbose"
}
],
"outputs": [
{
"type": "ApplicationInsights",
// (replace the following value with your AI resource's instrumentation key)
"instrumentationKey": "XXXXXXXXXXXXXXXXXXXXXX",
"filters": [
{
"type": "metadata",
"metadata": "metric",
"include": "ProviderName == mystatefulservice && EventName == ProcessedCountMetric",
"operationProperty": "operation",
"elapsedMilliSecondsProperty": "elapsedMilliSeconds",
"recordCountProperty": "recordCount"
}
]
}
],
"schemaVersion": "2016-08-11"
}
In ServiceEventSource.cs
[Event(ProcessedCountMetricEventId, Level = EventLevel.Informational)]
public void ProcessedCountMetric(string operation, long elapsedMilliSeconds, int recordCount)
{
if (IsEnabled())
WriteEvent(ProcessedCountMetricEventId, operation, elapsedMilliSeconds, recordCount);
}
EDIT
Adding diagnostics pipeline code from "Program.cs in fabric stateful service
using (var diagnosticsPipeline =
ServiceFabricDiagnosticPipelineFactory.CreatePipeline($"{ServiceFabricGlobalConstants.AppName}-mystatefulservice-DiagnosticsPipeline")
)
{
ServiceRuntime.RegisterServiceAsync("mystatefulserviceType",
context => new mystatefulservice(context)).GetAwaiter().GetResult();
ServiceEventSource.Current.ServiceTypeRegistered(Process.GetCurrentProcess().Id,
typeof(mystatefulservice).Name);
// Prevents this host process from terminating so services keep running.
Thread.Sleep(Timeout.Infinite);
}
Event Source is a tricky technology, I have been working with it for a while and always have problems. The configuration looks good, It is very hard to investigate without access to the environments, so I will make my suggestions.
There are a few catches you must be aware of:
If you are listening etw events from a different process, your process must be running with a user with permissions on 'Performance Log Users. Check which identity your service is running on and if it is part of performance log users, who has permissions to create event sessions to listen for these events.
Ensure the events are being emitted correctly and you can listen to them from Diagnostics Events Window, if it is not showing there, there is a problem in the provider.
For testing purposes, comment out the line if (IsEnabled()). it is an internal check to validate if your events should be emitted. I had situations where it is always false and skip the emit of events, probably it cache the results for a while, the docs are not clear how it should work.
Whenever possible, use the EventSource from the nuget package instead of the framework one, the framework version is full of bugs and lack fixes found in the nuget version.
Application Insights are not RealTime, sometimes it might take a few minutes to process your events, I would recommend to output the events to a console or file and check if it is listening correctly, afterwards, enable the AppInsights.
The link you provide is quite outdated and there's actually a much better way to log application error and exception info to Application insights. For example, the above won't help with tracking the call hierarchy of an incoming request between multiple services.
Have a look at the Microsoft App Insights Service Fabric nuget packages. It works great for:
Sending error and exception info
Populating the application map with all your services and their dependencies (including database)
Reporting on app performance metrics,
Tracing service call dependencies end-to-end,
Integrating with native as well as non-native SF applications
i've deployed a vm using Resource Manager deployment model.
Using rest api as described here: https://msdn.microsoft.com/en-us/library/azure/mt163682.aspx
i'm able to get informations about my VM. But i cannot see if the VM is running or not. I want that information to start/stop the VM Automatically via code.
Does anyone have tried that and get the VM powerstate?
best regards...
i make a GET using this URI
string.Format("https://management.azure.com/subscriptions/{0}/resourceGroups/{1}/providers/Microsoft.Compute/virtualMachines/{2}?api-version={3}", subscriptionID, resssourcegroup, vmname,apiversion);
apiversion is 2016-03-30.
The API call for this information is:
https://management.azure.com/subscriptions/{subscription-id}/resourceGroups/{resource-group-name}/providers/Microsoft.Compute/virtualMachines/{vm-name}/InstanceView?api-version={api-version}
Needed to use the second request uri "Get information about the instance view of a virtual machine" from the following url https://msdn.microsoft.com/en-us/library/azure/mt163682.aspx to get the instance powerstate.
Thank you.
This is the link to the documentation where you can see the Status of the VM:
https://learn.microsoft.com/en-us/rest/api/compute/virtual-machines/instance-view?tabs=HTTP
This is an example of the output
"statuses": [
{
"code": "ProvisioningState/succeeded",
"level": "Info",
"displayStatus": "Provisioning succeeded",
"time": "2022-07-25T02:12:52.7726725+00:00"
},
{
"code": "PowerState/running",
"level": "Info",
"displayStatus": "VM running"
}
]
I have created a Activit Process using Service Tasks etc with eclipse and deployed the .bar to Activiti which is running on tomcat. It was successfully deployed I can start my process using activiti-explorer without any issue. The deployed process name is "My process" and it is listed under Processes->Deployed Process Definitions in the Activiti-Explorer as well. In the diagram it has the name "myProcess:1:1473"
But I have two questions.
I need to start my process using REST call. (i.e. Without using Activiti-explorer) . What is the URL for that? I tried several variations of (http://localhost:8080/activiti-rest/service/runtime/process-instances) but none of them working.
When I restart the tomcat my process instance is not shown in the Activit -explorer. Each time I restart I need to redeploy the process .bar file. Is that the natural behavior of the engine?
For your first question check this guide for further details:
POST runtime/process-instances should be your endpoint (Be sure to make a POST request, with application/jsonas your content type)
The payload on the other hand should be formatted in one of three templates:
Request body (start by process definition id):
{
"processDefinitionId":"oneTaskProcess:1:158",
"businessKey":"myBusinessKey",
"variables": [
{
"name":"myVar",
"value":"This is a variable",
}
]
}
Request body (start by process definition key):
{
"processDefinitionKey":"oneTaskProcess",
"businessKey":"myBusinessKey",
"tenantId": "tenant1",
"variables": [
{
"name":"myVar",
"value":"This is a variable",
}
]
}
Request body (start by message):
{
"message":"newOrderMessage",
"businessKey":"myBusinessKey",
"tenantId": "tenant1",
"variables": [
{
"name":"myVar",
"value":"This is a variable",
}
]
}
As for your second issue, you should be aware that the OOTB (Out Of The Box) config may involve automatic DB cleaning upon each and every restart, you need to locate that config and override it with values of your choice! Check this section for further info, the databaseSchemaUpdate param might be exactly what you are looking for!
