We've got SANnav working in our test environment, in that everything is connected, all in sync, no SNMP errors, switches/hosts/storage ports all reporting healthy, no errors/warnings in the event log. But we've hit a weird issue whereby we can't see any historical performance stats, but we can generate real-time stats.
In the Investigate option on a SAN port, top right you have options of historical stats for 30 mins, 2 hours, etc..., or an option of Real-time. When we chose the default historical stats, we get nothing come up, no data points, "No data to display" on the graph area. However, as soon as we change from historical to real-time the stats appear, data points get written to the graph every 10 seconds, and we get a real-time graph.
So to me, logically, if the real-time performance monitoring is working, then the config of the switch and SANnav must be correct, but why is the historical graphs showing no data? We have a mix of switches/directors in Access Gateway mode, and normal switch mode. The normal switches show in the SANnav Inventory show the switches are bound successfully to the SANnav IP address.
We are stumped as to why real-time works, and historical does not. We are running SANnav 2.1.1.
Anyone have any ideas as to the reason why, what we can do to allow SANnav to trap historical data?
Just to add a curve ball in to this, we have in the same envionment Network Advisor running alongside Spectrum Control, which is trapping historical stats just fine, but the new implementation of SANnav won't trap historical stats.
