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.
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.
While discussing Azure/OMS topics in the community I often see incorrect usage of OMS (Operations Management Suite). That is understandable of course as Microsoft hasn’t done good job at clearing out all the terms but I still think we should be using the correct term when posting questions or discussing OMS in forums and other sites. This can help us communicate better between each other and especially in forums could result to answering question faster. As we the move from OMS Portal to Azure Portal it was about time to write this blog post which I’ve intended to do for quite some time but always delayed due to different circumstances.
It took us some time but we’ve managed to update the one and only free OMS book. We had plans to release it earlier but unforeseen things has happened which prevented us to do it earlier. I hope you will understand but you will still enjoy it. The other authors and me put a lot of effort to get it out along with the reviewers.
The new query language of Log Analytics is not included in the book but that should not discourage you as the content is still relevant.
Go grab Inside the Microsoft Operations Management Suite for free. Let us know if you have any feedback.
I mostly would like to thank my fiancée for being patient with me and supporting me while I was writing my chapters.
