Setting up weekend thresholds?

Votes:

0

The way we use our PRTG monitoring is to output data from DBs into XML format. We use this to track transaction counts for our data loads. Over the weekends some of our clients send less data and the sensors go off every single time due to this.

Is there a way to have the thresholds modified to expect a slightly lower amount on a weekend? I know that when using XML the thresholds are set in stone from the first time they are sent to a sensor and cannot be changed even if you send a new LimitMaxError amount in the XML.

This is causing a lot of noise for us and I was wondering if anyone who uses PRTG or Paessler themselves had a workaround for this?

I know you can completely pause the sensor over the weekend but we monitor 7 days a week so we don't want to pause them but rather have it be possible to set lower thresholds over the weekend to account for the drop.

Hello J,
thank you for your inquiry and KB-Post.

You are right, as described here you can't change the LimitXXXError and LimitXXXWarning:

However, did you consider the approach suggested in this KB-Post? Instead of working with limits, use something like this to change the sensor's state:

write-host "<prtg>"
write-host "<error>1</error>"
write-host "<text>Value ($value) is above limit</text>"
write-host "</prtg>"

The downside is that a sensor in error state has no values. Limits in comparison continue with measurements even in error state.

You could also assign a Schedule to the Notification, this way monitoring goes on but notifications are paused. Does this help?

If none of the above helps, you could also use a scheduled task that interact's with PRTG's API to change the limits. However, this may become unpractical depending on the amount of sensors. Please refer to:

Best Regards,
