AzureDiagnstics table is used by many Azure Services when you send diagnostic logs thus the 500 column limit that Microsoft is trying to fix for that table. When you hit that limit there is currently the described workaround but let’s say you have used one service that was sending logs and you no longer use that service. The logs associated with that service are yet to purged but you also want to clean up any custom columns that the service was using. That way you can free some slots for new custom columns for new services that will send logs to AzureDiagnostics table. Of course you can delete the custom column from Log Analytics blade but you do not want to delete a custom column that is also used by another service. This will be a short blog post that I will show you how to find if custom column is used by more than one service by using Kusto query language.
I have been away from blogging for a while as I needed to dedicate some more time to my family but now I am back with new blog post. Today’s topic we will focus on two Azure Monitor features – Resource Health and Log Analytics. Resource Health is may be not so known feature of Azure Monitor. The service will basically track the health of your resources for specific known issues. Think of it like something between Service Health which monitors health for specific services rather resources on higher level and Log Analytics/Application Insights which allows you to monitor on lower level. Using all of them you can achieve end-to-end monitoring. There are a number of resources that are supported by resource health with a number of issues that are monitored. My advise is if you do not have any monitoring on an Azure resource you should at least create resource health alerts for it. Even if you have monitoring I would still advise to use resource health as it will alert you on things that you probably cannot or your are not checking with your monitoring.
In case you couldn’t catch the Inside Azure Management Virtual Summit live we have now uploaded the recordings. You can check them out at Inside Azure Management YouTube channel. Enjoy the free content.
As you know we recently have released the fourth edition of Inside Azure Management book. What is better then free book? – A free book and free virtual summit. Yes that is right we are organizing a free virtual summit titled Inside Azure Management. I must say the actual organization is mainly led by Peter Zerger so once again I would like to thank him for his efforts. The virtual summit will take place on 23rd of July. If you want to register you can check the official web site of the event. You will find some interesting sessions and speakers that you might not see so much on other events. I will be delivering a session titled "Exploring Configuration Management in Azure" which will focus on showing you the different configuration management options within Azure with focus on Azure Policy and Azure Resource Manager Deployments.
It is also important to say that if you like the summit and you want to help people you can check one of the causes we are supporting with this event.
Enjoy the summit!!!
The time has come to publish the Inside Azure Management v4 book. This is the only free book that focuses on Azure Management. If you want you can also support us with purchase from Amazon. Links for both the free and purchasable version you will find below. It is needless to say that the authors of this book Pete Zerger, Tao Yang and Kevin Greene and me have put a lot of effort. Additionally also Ryan Irujo, Alexandre Verkinderen and Bert Wolters have put also a lot of effort in authoring of certain chapters. I would like to thank to all authors for the great work. Comparing v3 to v4 release we have tried to make the existing content better with providing even more examples. Overall we have followed the same guidance as before: trying to give you less content that is already available and focus on tips, tricks, scenarios and examples. Any feedback you can send it to us via e-mail: insidemscloud (at) outlook.com. I hope that you will enjoy our work and you will find it useful.
