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
I have watched this video https://developer.apple.com/wwdc20/10168
and tried to implement Logger in my application.
Then I've tried to generate .logarchive file from my iPhone device using this command (as it was mentioned in the video):
sudo log collect --device --start '2021-09-07 10:00:00' --output logTest.logarchive
where the result was:
Archive successfully written to logTest.logarchive
However, when I double-click over this file it opens the Console.app but then it stays infinitely loading the .logarchive.
Some notes:
The file size is about 150Mb, so I believe is not related with this.
Am I doing something wrong? Can you please help me?
Thanks in advance
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.

How to Fix 'doesn't have get-task-allow' in LogEntry which was retrieved using OsLogStore.
Example log output :

The above log is not having a proper log Message . Kindly help me to resolve this isse

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?
