Syslog Receiver Probe Disconnected

Hello,

I'm having some issues with the syslog receiver. Every time I try and search for a data that doesn't exist the probe disconnects. I've had this issue for Over a year now. I did contact support and they confirmed it to be a bug, but i haven't heard anything since . I'm posting now because it would be nice to have syslog working with PRTG as i'm using it for other purposes. Just wondering if anybody else is having the below issue.

On the Juniper SRX router I send syslog structured data messages to PRTG syslog server which contain policy rule information. The PRTG syslog server is accepting them without any issues. It's when I need to troubleshoot and start needing to search through the messages that are getting sent by the Juniper router. I log into the web interface and click on devices and then go to the syslog sensor on the Juniper SRX. I then attempt to filter details on the data tab and as long as I search for data that exists the sensor works as expected. As soon as I search on a term that doesn't exist then you start to see the PRTG Probe process begins to consume memory until it reaches a limit of 3.6 GBs and then the CPU spikes and the probe disconnects.

Thanks

We're aware of this...limitation, I guess. According to previous tickets, the host sends rather many syslog messages to PRTG. Perhaps an alternative more suited for logging analysis, such as ELK Stack would work for you as well?

I'm already using graylog as this issue has been happening for over a year now. I was hoping to centralize syslog into PRTG to cut down on the amount of applications i use for monitoring and logging.

it's indeed a limitation, meaning PRTG can't handle the amount of syslog messages my router is sending it. As a test i reduced the amount of policies that log resulting in 90% less messages sent to PRTG. Once i did this the syslog receiver worked properly with no probe disconnects.

That's unfortunate as that's one of the reasons we purchased PRTG.

Thanks

Thanks for the update on this one. We've bumped the ticket internally to have it revisited - perhaps we can resolve this anytime soon.
