We have a case where monitoring Linux server via the Linux SNMP Platform connector results in below errors:
Could this error message be please further clarified --> "Discovery Failed"
Yes, using version 3.
Hi Reza,
We received a similar report recently for symptoms as you describe here, could you let us know a bit about how that issue occurred?
Are you using IP address or hostname?
Do you happen to know if the element was recently in timeout just before that issue started to manifest itself?
Or if you point a different element to the same device if it also has issues?
“Are you using IP address or hostname?”
Using hostname.
“Do you happen to know if the element was recently in timeout just before that issue started to manifest itself?”
The element first reports as timeout in streamviewer and then discovery fail reports follow.
“Or if you point a different element to the same device if it also has issues?”
rebuilding new elements against the same device show the same symptoms.
Other linux elements against other devices work and creating an element against the same problematic destination works in a different Dataminer system.
It does indeed look like the same as a software issue we have identified recently and are in the process of investigating.
Could you reach out to support.data-acquisition@skyline.be and techsupport@skyline.be with the information regarding your issue so that we can further investigate a fix and validate also your setup once it is available?
Thanks João, query submitted.
Hi,
"DISCOVERY FAILED" basically means that DataMiner tries to set up a connection with the SNMPv3 device, but is not able to do this. There could be different causes to end up in such a situation e.g., host name could not be resolved into an IP address, the device is not replying to the initial request to get the Engine ID (device is not reachable), credentials are wrong,...
In DataMiner 10.4.4.0 this message has been changed to give a more clear idea of what the current underlying problem is that leads to the timeout.
Regards,
Hi Reza,
Small question, are you polling the Linux server via SNMPv3?
