Using Triggers to Modify the Sensor's Status

Out of the box, PRTG will only change the sensor status for one single interval. If the next scan results in another status, the status will change accordingly.

There is a workaround which will apply to these sensor types:

• SNMP Trap Receiver Sensor
• Syslog Receiver Sensor
• WMI Event Log Sensor
• Event Log (Windows API) Sensor

Steps to Go

1. Open the channel settings of
   • the New Records channel of the Event Log sensors
   • the Errors channel of the Syslog Receiver or Trap Receiver sensor
2. Enter the value 0,00000001 into the Upper Error Limit (#/min) field. This will ensure, that the status will immediately change as soon as an alarm occurs and the limit is exceeded.
   Note: This is the default setting for the Syslog and Trap Receiver sensors.

3. This will set the sensor in down status as soon as a message that matches the sensor filter rules arrives. This will allow you to immediately trigger a notification.
4. Click the Notifications tab of the sensor and choose these settings:

This will immediately trigger a message and inform you about the issue.

Advanced Notes and Guides

We also want to provide you with information, which will allow you to display the Alarm status in PRTG until it's resolved. Therefore, follow these steps to setup the required API calls as well as the settings in PRTG:

1. Create a device with a Green IT Sensor

2. Create a new notification and choose Execute HTTP Action. This is where the PRTG API comes into play:
3. Enter this code:

http(s)://YourServerIP/api/simulate.htm?id=objectid&action=1&username=YourUserAccount&Passhash=YourPasshash 

• Note: You will find your passhash on the Setup | System Administration | User Accounts page for the respective user.
• Now you will be able to assign the correct object ID of the newly created Green IT sensor to the notification. This is fairly straight forward, just replace the objectid by the ID value shown on the Overview tab of your Green IT sensor.

• You can clear the simulated error status by right clicking the sensor's name and by clicking Resume

Result

Following this guide will allow you to quickly change the status of one sensor, based on a speed trigger or limit assigned to a particular sensor based on #/s results and to get a persistent overview of previews events.
