Powershell log parser examples

An Exchange organization may have send connectors that are believed to be no longer in use, for example a send connector used for shared SMTP namespace.

However when you are planning the removal of a send connector there is the concern that some email traffic may still be using that send connector, and so you want to investigate this further before making your change. One way of determining send connector usage is to analyze protocol logs. If you're not already familiar with protocol logging I wrote an article about it here that is a good starting place.

There are two possible values; None off or Verbose on. If protocol logging is not already set to Verbose you can turn it on using Set-SendConnector. A default protocol logging configuration will retain 30 days worth of logs, but you can start analyzing them after a day or so if that is all the time you think you will need to discover any systems still using the connector. Obviously for less used connectors the longer you wait the more chance you'll capture something. Refer to the protocol logging article if you need more help finding the path on your serverand then run the command:.

Knowing which recipients are still receiving email that is going over a particular send connector can be very useful in tracking down any stragglers among the mailboxes or applications that the connector was originally set up for, but that have not been migrated properly. As you can see in the examples above there is some very useful information contained within protocol logging that can help you determine whether a send connector is still being used in your Exchange Server organization.

Digging into SMTP logs is a time consuming process. In addition, The SMTP service sends hundreds of emails and tracking a specific session can be quiet a challenge.

I found that a session can be scattered around the log in a non-consecutive order. Boy, this tool is something. After experimenting with log parser I automated the process via PowerShell.

Labels: logparsersmtpw3c. I like how you've used the tools to come back and customize the coloring of the lines!

Hi, I based a bounce counter program on this post, only to find out later that this method doesn't actually work for high-volume senders because SMTP logs are not in linear sequential order. Here it is 9 years later and I still can't find a better or easier tool for gathering this information from a Windows SMTP log. I'm fairly comfortable with PowerShell, though not at all an expert.

I discovered that when running this from a 64 bit server, I needed to specify the explicit path to logparser. That much is all well and good. What's the fix for that? Yes, that's very useful yet.

Michael, I follow your suggestion but, for some reason, it doesn't work. No result displayed. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. Elven I installed logparser and it works great. I tried adding the path to the environmental variables but I still getting issues with "The term 'logparser' is not recognized as the name of a cmdlet, function, script file, or operable program.

By default, Get-EventLog gets logs from the local computer. To get logs from remote computers, use the ComputerName parameter. You can use the Get-EventLog parameters and property values to search for events. The cmdlet gets events that match the specified property values. This example displays the list of event logs that are available on the local computer.

The names in the Log column are used with the LogName parameter to specify which log is searched for events. The Get-EventLog cmdlet uses the List parameter to display the available logs. The Newest parameter returns the five most recent events. This example shows how to find all of the sources that are included in the most recent entries in the System event log. The Newest parameter selects the most recent events.

Group-Object uses the Property parameter to group the objects by source and counts the number of objects for each source. The NoElement parameter removes the group members from the output.

The Sort-Object cmdlet uses the Property parameter to sort by the count of each source name. The Descending parameter sorts the list in order by count from highest to lowest. The EntryType parameter filters the events to show only Error events.

The Source parameter specifies the event property. This command gets the events from the System event log on three computers: Server01, Server02, and Server The ComputerName parameter uses a comma-separated string to list the computers from which you want to get the event logs. This command gets all the events in the System event log that contain a specific word in the event's message.

It's possible that your specified Message parameter's value is included in the message's content but isn't displayed on the PowerShell console. The Message parameter specifies a word to search for in the message field of each event. The Newest parameter selects the most recent event object. The Source parameter specifies the application name, Outlook. The objects are sent down the pipeline to the Where-Object cmdlet.

The objects are sent down the pipeline to the Select-Object cmdlet. Select-Object uses the Property parameter to select the properties to display in the PowerShell console.When you enter a command at the command prompt, PowerShell breaks the command text into a series of segments called tokens and then determines how to interpret each token.

PowerShell breaks the following command into two tokens, Write-Host and bookand interprets each token independently. When processing a command, the PowerShell parser operates in expression mode or in argument mode:. In expression mode, character string values must be contained in quotation marks.

Numbers not enclosed in quotation marks are treated as numerical values rather than as a series of characters. The following table provides several examples of commands processed in expression mode and argument mode and the results produced by those commands.

Every token can be interpreted as some kind of object type, such as Boolean or string. PowerShell attempts to determine the object type from the expression. The object type depends on the type of parameter a command expects and on whether PowerShell knows how to convert the argument to the correct type.

The following table shows several examples of the types assigned to values returned by the expressions. When calling an executable program in PowerShell, place the stop-parsing symbol before the program arguments. This technique is much easier than using escape characters to prevent misinterpretation.

When it encounters a stop-parsing symbol, PowerShell treats the remaining characters in the line as a literal. The stop-parsing symbol is effective only until the next newline or pipeline character. To run this command in PowerShell 2. You may also leave feedback directly on GitHub.

Skip to main content. Exit focus mode. For example, if you type: Write-Host book PowerShell breaks the following command into two tokens, Write-Host and bookand interprets each token independently. When processing a command, the PowerShell parser operates in expression mode or in argument mode: In expression mode, character string values must be contained in quotation marks.

If preceded by one of these characters, the value is treated as a value expression. Example Mode Result Write-Output! For example, the following command calls the Icacls program. Is this page helpful? Yes No. Any additional feedback?One of the useful reports you can extract from message tracking logs is the daily email message traffic load for an Exchange server. I run this report almost every day we retain up to 30 days of message tracking logs so running every day is not required to look for any patterns or trends that may concern us.

The report can be quickly generated using Log Parser. Install it on the server and run the following query from the folder where the message tracking logs are stored. Pretty useful on its own, but if you plan to create graphical reports using this data you can save yourself a bit of time and let Log Parser generate the chart for you, as long as you have Office or the Office Web Components installed on the computer running Log Parser.

He works as a consultant, writer, and trainer specializing in Office and Exchange Server. Very useful script, thanks. Is there anything that needs to be modified in this string in order for it to process all of logs in the MessageTracking directory. Currently it will only process 19 out of 83 logs on one sever I have.

The script works just fine, i was wondering if we can tweak this script for a particular exchange database, your help is appreciated. Hi paul thanks again for this useful article,just one question,how can i make this amazing report for a specific mailbox? Paul, I am looking to have this script run everyday via task scheduler.

Is it possible to get this report for subdomains? Company X hosts emails for 10 different domains. Would like to get a report of total mail volume for each domain. You can create any query you like.

You can then modify the Log Parser query to filter to specific domains. Can I get that report in Exchange ? Hi Paul as i am planning to migrate from exchange to on premises. When i run your group command below. Log Parser Studio comes with some preset reports for that.

The path cannot contain any spaces. RegularExpression - This is used for regular expression searches to find a desired string in the log file.That's where you usually spot most of the pertinent messages. However, sometimes you also need to reference log files in textual format. For example, this is the case for the Windows Update log or the Firewall log. The Get-Content cmdlet can be useful in many situations, such as when displaying text or log files.

For instance, the following command line displays the whole content of the httperr1. Some log files are very long, and if you want to display them one page at a time, just pipe the content to the Out-Host cmdlet along with the -Paging parameter. Get Content with paging output. However, usually the last lines are the most relevant ones because they contain either the global success messages or fatal errors.

Thus, it's sometimes useful to view only the final lines of log files. Because some services write continuously to a log file, you may want to display new lines as soon as they appear. That's exactly the purpose of the - Wait parameter. Please note that Get-Content still continues to wait for new lines even when the process or service writing to the file has already stopped.

In the next example, the command line displays the last five lines of the WindowsUpdate. Get Content and wait. There's a blinking underscore on that last screen. This means the cmdlet is waiting for new lines to display. If you want to search for packets the firewall has dropped, you can use the command below. This searches all lines from the firewall log containing the word "Drop" and displays only the last 20 lines.

Fortunately, the - Pattern parameter accepts arrays as input, and you can provide several patterns to search.

About Parsing

All patterns are processed with the logical OR operator. For instance, the following command displays lines containing the word "error" or the word "warning" from the Windows Update agent log file. For this purpose, Select-String has another interesting parameter named - Contextwhich shows you the lines before and after the string matching the pattern. The following command searches for lines with the word "err" preceded and followed by a space.

It also displays the three lines before and after every match from the cluster log file.

Searching with Select String. The last screenshot shows that the line containing the pattern starts with a greater than symbol. But you can also see that the Select-String cmdlet displays the line number of the log file for each hit. Thus, if you spotted a specific line in the midst of log file, you can display only the context for this specific line by using the Get-Content cmdlet and piping the result to the Select-Object cmdlet associated with the First and Skip parameters.

For instance, the following command line displays lines 45 to 75 from the netlogon. This command directly opens the file without the need to download it locally first.

For example, the following command line downloads and opens the log file of the default IIS website.
