ASnull null when using ASN() function on 3.2-1721

[Ian Coetzee]

Hi Team,

After upgrading to 3.2-1721 we are unable to resolve ip addresses to ASN's, the result comes up as null. Previously we were on 3.1, can't remember the build number.

Increasing the log level, I am seeing the following

Dec 17 08:38:11 run-rt[358538]: FINER: decode header error, com.sflow.rt.B.F(Decoder.java:3574)
Dec 17 08:38:11 run-rt[358538]: FINER: decode header error, com.sflow.rt.B.h(Decoder.java:3774)
Dec 17 08:38:11 run-rt[358538]: FINER: decode header error, com.sflow.rt.B.F(Decoder.java:3574)
Dec 17 08:38:11 run-rt[358538]: FINER: decode header error, com.sflow.rt.B.h(Decoder.java:3774)

Perhaps an error in the parsing functions?

Kind regards

Hi Ian,

Thank you for reporting the problem. There is an issue with the 3.2-1721 build that affected asn (and country) lookups that we have fixed. Please download 3.2-1722 and confirm that it is working for you.

The "decode header error" messages you are seeing with the FINER log level aren't really errors, they are artifacts of the way the packet decoder works when there isn't enough data in the packet header to fully decode a field.

Hi Peter,

Thank you, appreciate the quick response. All happy now, ASN resolving.

One thing I noted, is under About the application still thinks it is build 1721.

Kind regards

Hi Ian,

Thanks again for your feedback. The 3.2 release moved from Java 11 to Java 17 so that we could use maintained versions of services that sFlow-RT depends on (e.g. Jetty 12). This ensures we have the latest security updates, but unfortunately, involved some major API changes and changes to the release process. I believe we have them sorted out now and we have updated 3.2-1722 release packages.

Regards,

Hello Peter,

I've tested 3.2-1722 build and Country is still not resolving, as example "World Map" provides no metrics. But I can confirm that ASN resolve is working fine.

Thank you for raising the issue - we missed a dependency. Release 3.2-1723 should fix the country lookup. Please let me know if you run into any issues.
