Viewing logs (classic)

Controller Integration for Browser Display

All that is required is to execute the method in a Controller that is mapped to a route:

A typical Controller (LogViewerController.php) will have the following content:

private $logViewer;

public function __construct() {
    $this->logViewer = new \CILogViewer\CILogViewer();

public function index() {
    echo $this->logViewer->showLogs();

Then the route (application/config/routes.php) can be configured thus:

$route = "logViewerController/index";

And that’s all! If you visit on your browser
you should see all the logs that are in application/logs folder and their content


The folder path for log files can be configured by adding clv_log_folder_path to CodeIgniter’s config.php file e.g.

The file pattern for matching all the log files in the log folder can be configured by adding
clv_log_file_pattern to CodeIgniter’s config.php file e.g.

Free File Viewer

Free File Viewer is a versatile file viewer that can open files of various formats. It supports opening log files as well and opens large log files quickly without affecting any other running task. It is such a fast large log file viewer that opening 1 GB large log files is a cake walk for this software. In terms of features, it is pretty basic. You can open a log file, and perform basic searches in it. It only shows one search result at a time, and you need to manually move to next search result. Apart from that, it really does not have any feature that make it a good log file viewer.

On the contrary, I noticed a couple of issues while installing it. It tried to change homepage of my browser without my permission. It also downloaded Real Player’s browser plugin, without asking me for the same.

So, I would suggest you to stay away from this, unless you are looking for a versatile file viewer that can support a lot of file formats (including image and video formats).

This tool has not been tested on Internet Explorer, but definitely won’t work on versions earlier than version 9.

Your web browser must support the video codec that your flight video uses in order to play it. Firefox doesn’t support
H.264 videos on Mac, so if your video won’t play, try Google Chrome instead. If it still won’t play, follow the
instructions in the next section to convert your video using Handbrake.

The best performing web browser tends to be Google Chrome, especially when trying to play your flight video at the same

This tool is currently in the Beta stage, so a number of key features have yet to be implemented:

  • There is no control over the amount of smoothing applied to the graph lines
  • There is no way to single-step between loop iterations with the arrow keys

Log Expert

Log Expert is a lightweight log viewer for Windows. This log file viewer is suitable for small log files. I was able to open a 300 MB log file in it, but a larger file didn’t open. It can open multiple log files in separate tabs. If you reopen the software, all tabs will be restored. The best part of this freeware is that you can edit a log file and save it on your PC. Like some other log viewer software in this list, it also displays the list of recently opened files, which provides you quick access. It opens a log file and displays its line numbers.

You can add bookmarks to any row and switch among added bookmarks easily. If you want to view all your added bookmarks, simply press F6 key. This log analyzer will open a window that contains all your added bookmarks. It also lets you export all bookmarks on your PC.

Filters: Use filters to modify your searches. You can make your searches case sensitive, invert your matches, restrict columns, open filtered results in new tabs, etc.

Search Tool: You can start your search either from selected text or from top. Besides this, directional search is also available in this software, which lets you start search in forward or backward direction. It highlights all searched text within the entire log file with yellow color. This lets you recognize them easily. After the completion of a search, it shows all the lines that contain searched text along with their line numbers at its bottom part.

Encoding: It supports 5 types of encoding, which include: ASCII, Windows-1252, UTF8, etc.

File Peeker

File Peeker is a free lightweight log file reader which lets you open large log files quickly. The main advantage of this log file viewer is that it lets you specify the part of the log files that you want to view. For example, you can specify that you want to start viewing the log file starting 22,000 bytes, and view 10,000 bytes from there on. You can also specify this in percentage, that where do you want to start viewing your log file from, and then what percentage of it you want to view. I wish it had option to specify this information in terms of number of lines as well, but that feature is missing.

So, if you have a very large log file, but you know which part of it you want to view, then this freeware log viewer will come very handy.

It does provide search as well, but the search feature is pretty basic. You can only search for an exact match string, and choose to perform the search case sensitive or non-case sensitive. It does not have any option to perform regex based search. Also, when you search for a string, it does not highlight all the instances of that string, but only the first instance is highlighted. You have to press Search button again to go to the next search result.

A good feature of search is that you can choose to search the entire log file, or only the part of the log file that you have chosen to view.

So, to summarize, if you want a log viewer that lets you view a specific part of a log file, then File Peeker is a good software for that. But if you want one with powerful search options, then you need to use some other log viewer from this list.

Giving a definition of the term “comedy”, one may face some difficulties as it’s one of the most complex categories of aesthetics. Comedy is historically volatile, it depends on the context and has a social nature. The laughter is not always a sight of comedy, and comedy is not always defined by laughter. It is circumstances, sharpening the contradictions and helping to reveal its social nature

Before you Begin

To connect to offline log files, an instance of SQL Server must be installed on the computer that you are using to view the offline log files, and on the computer where the log files that you want to view are located. If an instance of SQL Server is installed on both computers, you can view offline files for instances of SQL Server, and for instances that are running earlier versions of SQL Server on either computer.

If you are using Registered Servers, the instance that you want to connect to must be registered under Local Server Groups or under Central Management Servers. (The instance can be registered on its own or be a member of a server group.) For more information about how to add an instance of SQL Server to Registered Servers, see the following topics:

For more information about how to view offline log files programmatically through WMI and WQL queries, see the following topics:

  • SqlErrorLogEvent Class (This topic shows how to retrieve values for logged events in a specified log file.)

  • SqlErrorLogFile Class (This topic shows how to retrieve information about all SQL Server log files on a specified instance of SQL Server.)


Click the «Open log file/video» button at the top right and select your log file and your flight video (if you recorded one).

You can scroll through the log by clicking or dragging on the seek bar that appears underneath the main graph. The
current time is represented by the vertical red bar in the center of the graph. You can also click and drag left and
right on the graph area to scrub backwards and forwards.

Syncing your log to your flight video

The blackbox plays a short beep on the buzzer when arming, and this corresponds with the start of the logged data.
You can sync your log against your flight video by pressing the «start log here» button when you hear the beep in the
video. You can tune the alignment of the log manually by pressing the nudge left and nudge right buttons in the log
sync section, or by editing the value in the «log sync» box. Positive values move the log toward the end of the video,
negative values move it towards the beginning.

Customizing the graph display

Click the «Graph Setup» button on the right side of the display in order to choose which fields should be plotted on
the graph. You may, for example, want to remove the default gyro plot and add separate gyro plots for each rotation axis.
Or you may want to plot vbat against throttle to examine your battery’s performance.

Viewing logs using GNOME System Log Viewer

The GNOME System Log Viewer provides a simple GUI for viewing and monitoring log files. If you’re running Ubuntu 17.10 or above, it will be called Logs. Otherwise, it will be under the name System Log.

System Log Viewer interface

The log viewer has a simple interface. The sidebar on the left shows a list of open log files, with the contents of the currently selected file displayed on the right.

The log viewer not only displays but also monitors log files for changes. The bold text (as seen in the screenshot above) indicates new lines that have been logged after opening the file. When a log that is not currently selected is updated, it’s name in the file list will turn bold (as shown by in the screenshot above).

Clicking on the cog at the top right of the window will open a menu allowing you to change some display settings, as well as open and close log files.

There is also a magnifying glass icon to the right of the cog that allows you to search within the currently selected log file.

Native app build via NW.js

App build and release

The tasks are defined in and can be run through yarn:

List of possible values of :

  • dist copies all the JS and CSS files in the folder.
  • apps builds the apps in the folder .
  • debug builds debug version of the apps in the folder .
  • release zips up the apps into individual archives in the folder .

Running this task on macOS or Linux requires Wine, since it’s needed to set the icon for the Windows app (build for specific platform to avoid errors).

Setting up and building on a Mac

  • Install GitHub desktop application from and open the GitHub Desktop application.
  • At, select Clone or Download > Open in Desktop

(The GitHub Desktop application should come to the front and create a repository (not necessarily where you want it). The blackbox-log-viewer repository (folder) should appear under the list of local repositories. You can find your local repository location on your mac using the ‘Locate in Finder’ command GitHub Desktop It can be moved somewhere more else, but you’ll then need to tell Github where you’re moved it to.)

Open and install or update homebrew:

install node 8.x and yarn, if already installed, agree to update them

Change Terminal’s working directory wherever you put blackbox-log-viewer folder; easiest way is to type ‘cd ‘ in Terminal then drag the blackbox-log-viewer folder from the Finder to the terminal window. Or use a terminal command like

install dependencies into that folder (ignoring many confusing messages) with:

finally build the DMG itself, which will end up in blackbox-log-viewer/release/, with:

Build or release app for one specific platform

To build or release only for one specific platform you can append the plaform after the .
If no platform is provided, only for the platform you are builing from will be build.

  • MacOS X use
  • Linux use
  • Windows use
  • ChromeOS use

You can also use multiple platforms e.g. .

macOS DMG installation background image

The release distribution for macOS uses a DMG file to install the application.
The PSD source for the DMG backgound image can be found in the root (). After changing the source, export the image to PNG format in folder .

How to View Log Files: UniFi Security Gateways

To view log files under a USG:

1. Connect to the USG via SSH. 2. In the EdgeOS CLI, the log can be viewed by running the following commands:

General Logging

show log

IPsec VPN Logging

show vpn log 

FreeRADIUS Logging 

sudo cat /var/log/freeradius/radius.log

DNSmasq Logging

sudo cat /var/log/dnsmasq.log

IPS/IDS Engine Logging

sudo cat /var/log/suricata/suricata.log

3. View live logging.

To view the live logs, with output updating in your SSH session as new logs are appended, run the following instead of the cat command above.

tail -f /var/log/messages

User Tip:If a user would like to only get the last number of lines the tail utility can be used. The command below will output the last 10 lines of the radius.log file. 

sudo tail -n 10 /var/log/freeradius/radius.log

NOTE:Firewall logs aren’t in the UI yet. Please see this for more details.  

File Viewer Lite

File Viewer Lite is a free log file viewer which lets you open large log files quickly. It displays metadata and other information of opened file on its interface. For example, if I open a log file in this free log viewer, I will get alpha and omega of that file, which includes: file size, file location, date and time on which it was opened, date and time on which it was modified, etc. On the right side on its interface, entire log file is displayed along with the line numbers, Ruler, and Syntax Tree. There are options to hide one or any of these.

If I talk about the type of view, there are three types of views available for a log file, namely: Native, Text, and Hex view.

  • Native view is the original representation of a log file, i.e. it shows a log file in its original code. This is the default view.
  • Text view converts a log file and displays it in a coded text format.
  • Hex view converts a log file in Hexadecimal code and displays it on the interface.

A very useful feature of this freeware is Find Tool.

Find Tool: You can search a text in the entire log file by pressing Ctrl+F keys on your keyboard. Following are types of searches that are available in this free log viewer:

  • Case Sensitive
  • Whole Words Only
  • Regular Expressions Searches

This file viewer provides further options to customize the search:

  • Direction Search: Use this search mode to start search either in forward or in backward direction.
  • Origin Search: This type of search mode starts searching texts either from the position where you have placed cursor in a log file or from the beginning.

Apart from this, it also lets you edit a log file and export it on your PC as txt file. Cut, Copy, and Paste features are also available in this free log analyzer for PC.

Though this free log viewer comes with many good features, but I do not recommend it to you if you are looking for log viewers that can handle heavy files easily. This freeware is limited for small log files whose size do not exceeds 300 MB. I have tried 500 MB log file in this Windows log viewer, but it failed to open it and displayed a message “Not Sufficient Memory“. Hence, I suggests you to download it only if you are looking for a very basic log file viewer.

NOTE: Save feature is not available in its free version.

Trace data

When a log entry contains both the and the latency-related field, both
the latency and trace icon appear.

When a log entry contains only the field, then only the trace icon appears.

To view the trace data related to the log entry, click the trace icon. You have
the following options:

View trace details: Shows the parent span and child traces along with
details about the trace. To view more details about
the trace, navigate to Cloud Trace by clicking
View in Trace. For more information about the
content in the flyout panel, see Viewing trace details.

  • Show all logs for this trace: Refines and runs the query by adding the
    field set to the identifier of
    the trace associated with the log entry.

  • Show only traced requests: Refines and runs the query by adding the
    field set to . For more
    information on sampling, go to
