Hmm, seems very similar and was fixed in their code? Same issue?
https://issues.opennms.org/browse/NMS-8775
Observium Unable to parse header `DSName'.
Vs their ERROR: undefined vname ds
Grasping at straws ☺
Thanks, Sam

Hi,
There shouldn't really be any issue with 1.6, since that's what most people are running these days.
There doubly shouldn't be any issues, since it was 1.6 which created the file (as you deleted it!)
The only thing I can think of which would cause it is the rrdtool package, though! oO

as listed in the install docs http://yum.opennms.org/repofiles/opennms-repo-stable-rhel7.noarch.rpm
https://yum.opennms.org/stable/rhel7/rrdtool/
Now provides 1.6, and possibly broke those graphs. I’ll find out shortly. Thanks, Sam

This error is an error from rrdtool related to the RRD format. I don't see how we can do anything to affect this. Adam.

Anything I can retrieve to help verify if this a bug in the stable branch or system? Problem is limited to Netscaler TCP graphs and Graphs -> Netscaler SSL graphs
netscaler-stats-tcp.rrd netscaler-SslStats.rrd

This is likely because your rrd local files are corrupted.

So far I’ve only noticed it on specific Citrix Netscaler graphs, the Netscaler SSL ones nsSslHandshakes, nsSslSessions, etc and TCP Connections and TCP Packets for the netscalers are all in the same state with Unable to parse header `DSName'.

Sadly I didn’t notice when, I did recently upgrade to revision 8417, however these aren’t graphs I frequently look at. Anybody else with netscalers in their environment at the same revision?
