Merge-SPLogFile doesn’t return any records, but entries are there in SharePoint logs

When I run the below Merge-SPLogFile it throws me the warning

WARNING: Cmdlet did not return any records in the log file. Check your time range or filters.

Merge-SPLogFile -Correlation 2816f89e-8451-7054-1584-ad125aa03b3 -Path D:\Log.txt 

But when I checked the SharPoint logs it got messages for same correlation. I exported the logs using ULS viewer, but in my case there are multiple SharePoint WEB & APP Servers

Couple of months ago, it was returning me the records, but now it stopped working.

malformed URL in the logs

I have come across, malformed URL in the logs: 
It was part of a tier project. I wonder if it is related to URLs found in the verified URL file. if I double click one of them i get:
http//thedomain.com 
It fails because “:” is missing between http and //

UPDATE:
I checked in the verified URL lists. I didn’t find any issues. I think it is not related to GSA SER but I can’t delete this question.
SORRY

Automatic zipping and archival of older logs

As my disk space is less , i would need to zip and archive the logs in another directory which are older than 30 days.

Can someone please modify the below command to zip the 30 days older files and move it to destination folder.

find . -name ‘server.log*’ -mtime +30 -exec zip -r /home/user/Logs/ /opt/apps/log {} \;

where server.log is a log file and there will be many logs with datestamp attached like this server.log_290719. /home/user/Logs is destination folder and /opt/apps/log is source folder.

How to see see/configure Windows Defender Firewall logs in non-domain private Windows 10 Computer?

How to see see/configure Windows Defender Firewall logs in non-domain private Windows 10 Computer? Of course – I am aware of the answer How do I access a firewall log (Windows 10 w. Windows Defender) but it applies to workstations managed in the domain and by domain controller. I have simple, private workstation that is attached to the public network, no special domain, no domain controller. How can I manage Windows Defender Firewall logs without any references to some Windows domain?

Firewall logs with Local IP contacting local IP over the internet

I noticed some wierd behavior in our firewall logs: a computer in our subnet 192.168.1.0/24 sending UDP packets in port 161 to an IP in subnet 192.168.20.0 (we don’t have a subnet like that), and the packets going through the LAN to WAN policy. I have installed Sysmon in the computer that is creating this connection, but I don’t know what to look for in it. Does anybody in here have an idea of what is going on? I’m sorry if I’m not giving enough info. I don’t want to mess up giving too much details.

How to separate out the displaying of logs in the terminal from the logging data

I am trying to jump back into logging and it’s been a while. From what I remember, in the past I’ve logged things as JSON and saved it to a file or larger distributed system, and it was processed into the db and such async. But what I don’t recall is how it goes from the log call in the source code to the display on the terminal, like when you tail the Heroku logs in a Rails app.

enter image description here

The question is how you generally display the logs in the terminal while keeping them separate as raw data/json for the backend to process. Is there a stdout log that is also recording what is written to the terminal (stdout)? Are we instead reading from that file to get our backend logs? Or do we not have a log file for stdout and instead just do 2 things: (1) write to stdout without logs on it, and (2) write our JSON to our log server.

Wondering generally how it’s done.

I ask because I would like to display a better more pretty version of the logs in the terminal, yet still keep them as JSON data in the backend.

Ubuntu 19.04 logs out randomly after first sleep

I just installed Ubuntu 19.04 on my computer, and ever since I installed it, I’ve been getting this weird bug where, after the first sleep, if I try to log in again, Ubuntu will keep logging out. The only way I’ve been able to bypass this is by powering off my computer (by holding down the power button), and logging in again. Any thoughts on how to fix this?

Wakeup device is filling all my logs on Ubuntu ARM

I use Ubuntu on a Rasperry PI like board, and all my storage ( 3GB ) is filled by logs:

How can I see where it comes from and how not to log it ?
