I am trying to obtain metrics for an Azure Virtual Machine. The standard Insights API provided doesn't provide all the metrics. Upon more reading I found that these metrics are stored in Azure Storage Accounts under different tables. Is there a way to make an API call to these tables and retrieve the metrics ?
There are two categories of metrics for Azure Virtual Machine -- host level metrics that are derived from Hyper V performance counters and the guest level metrics that come from within the VM itself.
For host level metrics, the Insights REST API provides access to this data.
https://learn.microsoft.com/en-us/azure/monitoring-and-diagnostics/monitoring-overview-metrics
For guest metrics such as Memory metrics, you need to install the diagnostics agent to collect this data to one of the supported sink types such as storage account, event hub, or Application Insights. If you collect this data to storage account or event hub, you need to use the standard storage API or event hub API to access this data. Specifically for storage, the data will be stored in WADPerformanceCountersTable in Azure table storage. There is no additional REST API to retrieve this data outside of the existing storage API.

I want to view logs in azure, I mean logs that I have in the console in localhost where I can find them in web site deployed in azure? I am consuming an external API and I want to see what I send and what I received from the prod env
thank you
There are couple of ways to track logs in Azure
Azure API Management
Azure Monitor
Azure API Management helps you track all kinds of requests including
View activity logs
View resource logs
View metrics of your API
Set up an alert rule when your API gets unauthorized calls
Azure Monitor on the other hand helps it possible to programmatically retrieve the available default metric definitions, granularity, and metric values.
The data can be saved in a separate data store such as Azure SQL Database, Azure Cosmos DB, or Azure Data Lake. From there additional analysis can be performed as needed.
We are working on implementing a new project in Azure. The idea is to move out of on-premise systems into the cloud as we have our vendors, partners and clients moving into the cloud. The option we are trying out is to use Azure Data Share and have Azure SQL Database subscribe to the data.
The thing we are now trying to explore is once a new data snapshot is created how do we import this data into Azure SQL Database?
For instance we have Partner information and this information is made available via Azure Data Share and new data snapshot is created daily.
The part that I am not sure of is how to synchronize this data between Azure Data Share and Azure SQL Database.
Also, Is there an api available to expose this data out to external vendors, partners or clients from Azure SQL Database after we have data sync to Azure SQL Database from Azure Data Share?
Azure Data Share -> Azure SQL Database
Yes, Azure SQL Database is a supported.
Azure Data Share -> SQL Server Database (on-prem)? Is this option supported?
No, SQL Server Database (on-prem) is not supported.
Is there an api that could be consumed to read data?
Unfortunately, there is no such API that could be consumed to read data.
Azure Data Share enables organizations to simply and securely share data with multiple customers and partners. In just a few clicks, you can provision a new data share account, add datasets, and invite your customers and partners to your data share. Data providers are always in control of the data that they have shared. Azure Data Share makes it simple to manage and monitor what data was shared, when and by whom.
Azure Data Share helps enhance insights by making it easy to combine data from third parties to enrich analytics and AI scenarios. Easily use the power of Azure analytics tools to prepare, process, and analyze data shared using Azure Data Share.
Which Azure data stores does Data Share support?
Data Share supports data sharing to and from Azure Synapse Analytics, Azure SQL Database, Azure Data Lake Storage, Azure Blob Storage, and Azure Data Explorer. Data Share will support more Azure data stores in the future.
The below table details the supported data sources for Azure Data Share.
How to synchronize this data between Azure Data Share and Azure SQL Database.
You need to choose “Snapshot setting” to refresh data automatically.
A data provider can configure a data share with a snapshot setting. This allows incremental updates to be received on a regular schedule, either daily or hourly. Once configured, the data consumer has the option to enable the schedule.
I was monitoring microsoft.compute using a REST API Client and I was hoping that I could do the same for microsoft.storage. But unfortunately I get an error response while trying to do so
{
"code": "ResourceNotSupported",
"message": "Resource provider not supported: microsoft.storage"
}
The Rest API call I make is something similar to this
https://management.azure.com/subscriptions/xxxxxxxx/resourceGroups/xxxxx/providers/Microsoft.Storage/storageAccounts/xxxxx/providers/microsoft.insights/metricdefinitions?api-version=2016-03-01
Is there any way to get storage metrics from a REST API client?
Storage metrics are stored in a table called $MetricsTransactionsBlob. You will need to use the data plane APIs described in this link.
Simply you will need to access and query the table at https://<accountname>.table.core.windows.net/Tables("$MetricsTransactionsBlob")
There is no Azure Insights for Azure storage. You can use Storage analytics to get at the monitoring data that's stored in associated Table storage of the monitored account, but this will fail for Blob and Premium storage accounts. This is a big oversight from the Azure API perspective. For Standard Azure storage, you can get at the metric tables via the link that #Sercan provided.
If you're trying to monitor utilization of your VM disks on Premium or Blob accounts, you can use Physical Disk performance counters on the actual VMs to measure the throughput, IO requests, etc. This is what we advise our CloudMonix users do when they have this need.
I am trying the read the performance metrics of vms in the azure cloud using the rest api. As per the this link ( azure documentation ) http://www.windowsazure.com/en-us/documentation/articles/cloud-services-how-to-monitor/#accessverbose
but when i try to fetch the tables that are available for a particular from a storage account i am not getting empty table list.
Please correct me what the ways we can capture vm performance metrics using the rest api to integrate with 3rd party system management providers.
I am trying to implement azure storage metrics code in my role but i am checking if there is easy way to get azure storage metric data about my files usage. my code is stable and i do not want to change code again.
Actually if you already have Windows Azure role running, then you don't need to make any changes to your code and you still can get Windows Azure Blob storage Metrics data.
I have written a blog about it last time as Collecting Windows Azure Storage REST API level metrics data without a single line of programming, just by using tools
Please try above and see if this works for you.
Storage analytics is disabled by default, so any operations against your storage up til now has not been logged for analysis.
You may choose to enable analytics at any time, for both logging (detailed access information for every single object) and metrics (hourly rollups). Further, you may choose which specific storage service to track (blobs, tables, queues) and which operations to track (read, write, delete). Once analytics are enabled, you may access the resulting analytics data from any app (as long as you have the storage account name + key).
Persistent Systems just published a blog post on enabling storage analytics for Java apps. The same principles may be applied to a .net app (and the sdk's are very similar).
Additionally, Full Scale 180 published a sample app encapsulating storage analytics (based on REST API, as it was written before SDK v1.6 came out).
