Hi all

I have an event viewer query in the form of an .xml file which loads when S+ starts. Basically it's a filter which displays a few relevant things in event viewer.

In my case the filter filters and shows Windows sleep, shutdown, boot-up events. This is how I keep track of who logged in and when, to Windows.

Is there a way to fetch the data directly from the event viewer into S+ so it can be displayed *neatly* or stored elsewhere?

Searching online gives ways to do something similar(?) on power shell such as here: Use PowerShell to Query All Event Logs for Recent Events

This is not a high priority thing but any pointers are much appreciated.
Thanks
Rob

I'm pretty sure I have System.Diagnostics included in the script engine, so you should be able to get this to work with some refactoring

Thanks for the pointer Rob

I have tried this so far,
Code:
var myLog = new System.Diagnostics.EventLog();

myLog = System.Diagnostics.EventLog.GetEventLogs();

var n = 2;
myLog[n].Log; //contains log name
myLog[n].LogDisplayName; //contains read-friendly log name
myLog[n].Entries.Count; //contains count of entries in the log


MS Documentation gives examples but I am unable to convert them for S+ properly such as How to: Query for Events, sample:
Code:
' Query two different event logs using a structured query.
        Dim queryString As String = _
                "<QueryList>" & _
                "  <Query Id=""0"" Path=""Application"">" & _
                "    <Select Path=""Application"">" & _
                "        *[System[(Level &lt;= 3) and" & _
                "        TimeCreated[timediff(@SystemTime) &lt;= 86400000]]]" & _
                "    </Select>" & _
                "    <Suppress Path=""Application"">" & _
                "        *[System[(Level = 2)]]" & _
                "    </Suppress>" & _
                "    <Select Path=""System"">" & _
                "        *[System[(Level=1  or Level=2 or Level=3) and" & _
                "        TimeCreated[timediff(@SystemTime) &lt;= 86400000]]]" & _
                "    </Select>" & _
                "  </Query>" & _
                "</QueryList>"

        Dim eventsQuery As New EventLogQuery("Application", PathType.LogName, queryString)
        Dim logReader As New EventLogReader(eventsQuery)

        ' Display query results.
        DisplayEventAndLogInformation(logReader)



On a similar note, I found a power shell query to fetch required logs such as
Code:
Get-EventLog -LogName System -InstanceId 1 -Newest 1 //can be customized according to event ID, source, message text and so on.


Is there a way to get power shell output (as input) in S+ in the form of string or something so it can be displayed neatly? Crying

You can probably get the output from a PowerShell command by redirecting the standard output. See this post, search for "redirect"

https://forum.strokesplus.net/posts/t8434-Searching-text-file-contents-in-background

However, this script sample should help you along working within S+:
Code:
var allEventLogs = System.Diagnostics.EventLog.GetEventLogs();
var systemEventLog = -1;

// Find the System event log
for(var i = 0; i < allEventLogs.Count(); i++) {
    //StrokesPlus.Console.Log(allEventLogs[i].Log);
    if (allEventLogs[i].Log == "System") {
        systemEventLog = i;
    }
}

// Start at the end of the event log and work backward (most recent first)
for(var i = allEventLogs[systemEventLog].Entries.Count - 1; i > 0; i--) {

    // EventLogEntry Properties:
    //https://docs.microsoft.com/en-us/dotnet/api/system.diagnostics.eventlogentry?view=dotnet-plat-ext-6.0
    let entry = allEventLogs[systemEventLog].Entries.Item(i);

    // Looks like these types will show logoff/shutdown/etc (but see link in next section for better details)
    if(entry.EntryType.ToString() == "Information" 
       && entry.Source == "User32") {
        StrokesPlus.Console.Log(`${entry.TimeGenerated.ToString("yyyy-MM-dd hh:mm:ss tt")} - ${entry.EntryType.ToString()} - ${entry.Source} - ${entry.Message}`)
    }

    // Below are just 2 events I found to map here, the post below seems to cover a variety of event sources and IDs
    // https://serverfault.com/questions/885601/windows-event-codes-for-startup-shutdown-lock-unlock
    if(entry.EntryType.ToString() == "Information" 
       && entry.Source == "Microsoft-Windows-Kernel-General") 
    {
        switch(entry.EventID) {
            case 12:
                StrokesPlus.Console.Log(`${entry.TimeGenerated.ToString("yyyy-MM-dd hh:mm:ss tt")} - ${entry.EntryType.ToString()} - ${entry.Source} - System Started`)        
                break;
            case 13:
                StrokesPlus.Console.Log(`${entry.TimeGenerated.ToString("yyyy-MM-dd hh:mm:ss tt")} - ${entry.EntryType.ToString()} - ${entry.Source} - System Shudown`)        
                break;
        }
        
    }
}
