How to move Cloudwatch logs across regions?


How to move Cloudwatch logs across regions?



I'm currently exploring an AWS setup using Lambda@Edge to capture metrics from viewer requests. Since I cannot control where the logs will end up (it simple ends up in Cloudwatch in the region closest to the request origin) I somehow need to transfer logs between regions.



I currently have an ElasticSearch cluster in eu-west-1 where I would ultimately want to ingest all my logs, from all regions.
What is the recommended approach to move logs in CloudWatch from one region into and ElasticSearch cluster in another region?

I think you have two options.



You can stream all of your log groups to lambda and have lambda post
to ElasticSearch (repeat for every region).



You can stream your log groups to ElasticSearch as if it were in
another account (repeat for every region). This would require a public endpoint for your ElasticSearch cluster.





Can you explain how to setup the streaming directly to ElasticSearch? When I click "Stream to ElasticSearch" on any loggroup except eu-west-1, the option "This account" is selected and it says "You don not have any Elasticsearch clusters in this region". Or I can select "Other account". But my ES cluster is not in another account...

It may not be in another account, but you need to treat it as if it were. When you select other account you can enter an ARN and endpoint (must be public).

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false. I added itms-apps to my plist: LSApplicationQueriesSchemes and put this in my app delegate: func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return true } func moreTapped() { let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877") if #available(iOS 10.0, *) { UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in }) } else { UIApplication.shared.openURL(url! as URL) } } Are you testing on a real device? – rmaddy Jun 21 at 23:57 I try on a device, get "Cannot Connect to App Store".

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
