Is it possible to get the URL access log when a client access websites via Open Proxy (I mean the proxy outside of the organization) as a system log? Of course I think browser history records the access URL but it is not a log. Than you in advance.

It seems like signposts generated with os_signpost() APIs are not appearing in the trace files collected with ktrace (ktrace artrace). On the other hand, if the signposts are generated with kdebug_signpost APIs - they do show up correctly. Is this expected behavior? Specially since the kdebug_signpost APIs are now deprecated? Thanks. Devendra. ps: The os_signpost generated signposts do appear if capturing with Instruments app, just that they are not captured by ktrace.

Hi, all. I try logging some message of my console application. Just like syslog daemon in linux, I want to change and apply facility and level printing if requested. So, I just try to use syslog API and os_log API both of them. And try to change syslog.conf, add asl.configuration in /etc/asl directory But, it seems not to be applied. Only I can see, log messages can be gotten by using "log" command not saved to file. How can i config just like syslog system in linux and apply this? Thansk.

I'm looking to construct a custom logger API. For example: log.verbose(Date(), "Begun process") (That's contrived example, the point being some object and a message. I will then be manipulating both.) Within my Log object I then want to transform the date value and the message into a final log message. "Nanoseconds: 9790324:: Begun process". If I was working with strings, it would be a pretty simple issue. But I'm not. It looks like Logger, which actually does the logging takes in a OSLogMessage which I cannot instantiate and cannot pass by value or reference. Even if I had just: func verbose(_ date: Date, _ message: OSLogInterpolation) { log(date: Date, level: .info, message: message) } func info(_ date: Date, _ message: OSLogInterpolation) { log(date: Date, level: .default, message: message) } private func log(date: Date, level: OSLogType, message: OSLogInterpolation) { // Neither of these work log.log(level: level, message) log.log(level: level, OSLogMessage(interpolation: message)) } Ideally what I'd like is: private func log(date: Date, level: OSLogType, message: OSLogInterpolation) { let interpolation = "Nanoseconds: \(date.getNanoseconds):: " + message log.log(level: level, OSLogMessage(interpolation: interpolation)) } With the idea being that OSLogMessage is still respecting any privacy notices on the interpolation.

Hi, I am trying to collect OSLog's logs using the OSLog framework, but I am not being able to access them. I've seen some examples that use something like this: swift import OSLog let myLogStore =try OSLogStore(scope: .currentProcessIdentifier) but when I try to run it throws: bash main.swift:5:20: error: argument labels '(scope:)' do not match any available overloads main.swift:5:20: note: overloads for 'OSLogStore' exist with these partially matching parameter lists: (URL: URL), (url: URL) I couldn't find any solution on google so far... I am running it on a Mac OS X's 10.15 with Darwin Kernel Version 19 and Swift version 5.2.2 Any guidance on how to collect logs by using this framework will be highly appreciated

I have a Swift 3 Cocoa application that uses Apple's Unified Logging, like this: - import os class MyClass { @available(OSX 10.12, *) static let scribe = OSLog(subsystem: "com.mycompany.myapp", category: "myapp") func SomeFunction(){ if #available(OSX 10.12, *){ os_log("Test Error Message", log: MyClass.scribe, type: .error) } if #available(OSX 10.12, *){ os_log("Test Info Message", log: MyClass.scribe, type: .info) } if #available(OSX 10.12, *){ os_log("Test Debug Message", log: MyClass.scribe, type: .debug) } } }Within the Console application, both Include Info Messages and Include Debug Messages are turned on.When os_log is called, only the error type message is visible in the Console application.Using Terminal, with the command, all message types are visible in the Terminal output: -sudo log stream --level debugI've tried running the Console app as root, via sudo from the command line and the same issue occurs; no debug or info messages can be seen, even though they're set to being turned on under the Action menu.Setting system-wide logging to be debug, has no effect on the Console application output:sudo log config --mode level:debugPlease can someone tell me what I'm missing and how can I view debug and info messages in the Console application?
