There are two conditions to configure the monitor status:.You can add/remove multiple strings using the ( / -) button. Enter the string for which you want to check content matching in the Content to be searched text box.Under this window, select the severity criteria for Health (CRITICAL / WARNING / CLEAR) or Availability (UP / DOWN) from the Severity drop-down menu.This opens a new window where you can add new rules. You can add criteria based on which the content check can be performed to change the Health or Availability severity by clicking on the Create New Rule link.Select the required option under Monitor Severity to perform this content check to change the Health or Availability severity status.Choose between the File Parsing Options to perform a content check to Only appended content or the Whole File.If this checkbox is enabled, perform the following steps: For a File monitor, select the Do Content Check checkbox if you wish to run a content check.However, hostnames that are already present and configured for server monitoring cannot be deleted in this manner. The new hosts that are created can also be deleted by selecting the required host and clicking on the Delete Host link.Also, there is an option to Resolve Hostname / IP, enabling which will resolve the entered IP address to its corresponding hostname. Select the Mode Of Monitoring ( WMI for Windows, Telnet / SSH for Linux), the port and the Command Prompt, if required. You can either enter the credential details like user name, password, the command prompt or select the required credential from the Credential Manager list. You can create a new host by entering a new hostname / IP address and login credentials of the host.If it is in the Remote Server, either select the Host Name from the dropdown or create a new host, and then provide the file / directory's absolute path.If it is in the Local Server, provide the absolute path to the file / directory.Specify whether the File / Directory to be monitored is in the Local or Remote Server.Select whether it is a File or Directory monitor. ![]() Provide a Display Name for the monitor.From the New Monitor link, select File / Directory Monitor.To create a file / directory monitor, follow the steps given below: Using the REST API to add a new File/Directory monitor: Click here Configuring RCA Message for File Monitor.PS> Get-EventSubscriber | Unregister-EventĪt this point, the subscriber has been removed and we're back to where we started. Then, to remove them, use the Unregister-Event cmdlet. We can view all existing subscribed events by using the Get-EventSubscriber command. This will continue to monitor this folder until the PowerShell session ends. This message came from the watcher we created. Our New-Item command didn't return anything since the output was sent to $null, but we did get a message saying the file was created. PS C:\> $null = New-Item -path 'C:\FolderWhereStuffChanges\file.txt' -ItemType FileĬ:\FolderWhereStuffChanges\file.txt was Created at 15:42:35 Let's now drop a file into the C:\FolderWhereStuffChanges folder and see what happens. Id Name PSJobTypeName State HasMoreData Location Command PS> Register-ObjectEvent $watcher 'Created' -Action $action To do that, I'll use the Register-ObjectEvent cmdlet and provide it the watcher object we created, as well as the type of action to monitor. Now that I have the watcher object and the action I'd like to take when a file is created, I then need to register this event. Write-Host "$path was $changetype at $(get-date)" This is a variable that will be present every time an event fires and contains information such as the file path and the type of event that fired. As you can see below, I'm using the built-in variable. We define this action by creating a PowerShell scriptblock. There are different types of events you can "watch," such as new files or modified files, but in this article we're just going to focus on new files. For simplicity, I'll write output to the console with the name of the path of the file that gets created and the type of event. I now need to define some action to take when the event fires. $watcher.Path = 'C:\FolderWhereStuffChanges' ![]() I do that with the Path property, and since I want the watcher to raise events when one happens, I'll also set the EnableRaisingEvents property to $true. I also need to specify which folder I'll be monitoring. To do that, I'll assign the IncludeSubdirectories property. ![]() For example, I'll be monitoring a folder for new files and perhaps I'd like to monitor all subfolders, as well. Once you've instantiated the object, you can then provide various "parameters" to the watcher by assigning values to different object properties. $watcher = New-Object System.IO.FileSystemWatcher
