PRTG Manual: WMI Event Log Sensor
The WMI Event Log sensor monitors a Windows log file via Windows Management Instrumentation (WMI).
You can individually set the sensor to a specific status according to a new event log entry.
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

Consider the following remarks and requirements for this sensor:
Remark |
Description |
---|---|
Performance impact |
This sensor has a very high performance impact. We recommend that you use no more than 50 of this sensor on each probe. |
WoW64 |
This sensor requires WoW64 (Windows 32-bit on Windows 64-bit) for target systems that run Windows Server 2016. |
Credentials |
This sensor requires credentials for Windows systems. |
IPv6 |
This sensor supports IPv6. |
Knowledge Base |
|
Hosted probe |
You cannot add this sensor to the hosted probe of a PRTG Hosted Monitor instance. If you want to use this sensor, add it to a remote probe device. |
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- wmieventlogsensor

Log File |
The Windows log file that this sensor monitors. |
Result Handling |
Define what PRTG does with the sensor result:
In a cluster, PRTG stores the result in the PRTG data directory of the master node. |

Event Type |
Specify the type of event that this sensor processes:
The sensor cannot process other event types. |
Filter by Source |
Filter all received events for a certain event source:
|
Filter Type |
This setting is only visible if you select Enable above. Select the filter type:
|
Match String (Event Source) |
This setting is only visible if you select Enable above. Enter an event source that you want to filter for. Depending on the kind of filter, the sensor either processes the event source (Include filter option) or it does not process it (Exclude filter option). Enter a string. |
Filter by ID |
Filter all received events for a certain event ID:
|
Filter Type |
This setting is only visible if you select Enable above. Select the filter type:
|
Match Values (Event ID) |
This setting is only visible if you select Enable above. Enter an event ID that you want to filter for. Depending on the kind of filter, the sensor either processes the event ID (Include filter option) or it does not process it (Exclude filter option). The WMI Event Log supports more than one event ID. You can enter a comma-separated list of event IDs to filter for more than one ID. For example, 1100,4627,4747,4884,5050,6422. |
Filter by Category |
Filter all received events for a certain event category:
|
Filter Type |
This setting is only visible if you select Enable above. Select the filter type:
|
Match String (Event Category) |
This setting is only visible if you select Enable above. Enter a category that you want to filter for. Depending on the kind of filter, the sensor either processes the event category (Include filter option) or it does not process it (Exclude filter option). Enter a string. |
Filter by User |
Filter all received events for a certain event user:
|
Filter Type |
This setting is only visible if you select Enable above. Select the filter type:
|
Match String (Event User) |
This setting is only visible if you select Enable above. Enter a user name that you want to filter for. Depending on the kind of filter, the sensor either processes the event user (Include filter option) or it does not process it (Exclude filter option). Enter a string. |
Filter by Computer |
Filter all received events for a certain event computer:
|
Filter Type |
This setting is only visible if you select Enable above. Select the filter type:
|
Match String (Event Computer) |
This setting is only visible if you select Enable above. Enter a computer name that you want to filter for. Depending on the kind of filter, the sensor either processes the event computer (Include filter option) or it does not process it (Exclude filter option). Enter a string. |
Filter by Message |
Filter all received events for a certain event message:
|
Filter Type |
This setting is only visible if you select Enable above. Select the filter type:
|
Match String (Event Message) |
This setting is only visible if you select Enable above. Enter a message that you want to filter for. Depending on the kind of filter, the sensor either processes the event message (Include filter option) or it does not process it (Exclude filter option). Enter a string. You must use the percent sign (%) as wildcard for any or no character if you want to check if the string is part of the message. Otherwise, the whole event message must match the string. For example, you can enter %RAS% for any event message that contains the string RAS. |

Primary Channel |
Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor. You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab. |
Graph Type |
Define how this sensor shows different channels:
|
Stack Unit |
This setting is only visible if you select Stack channels on top of each other above. Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so. |
By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click under the corresponding setting name to disable the inheritance and to display its options.
For more information, see section Inheritance of Settings.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

Description |
---|---|
Downtime |
In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status |
New Records |
The number of new records This channel is the primary channel by default. |
