Hallo,
in our environment we are using among others these interconnects:
- Synergy 12Gb SAS Connection Module
- Synergy 20Gb Interconnect Link Module
- Virtual Connect SE 16Gb FC Module for Synergy
- Virtual Connect SE 40Gb F8 Module for Synergy
As far as I saw in the REST API interface reference for my OneView, the interface
'GET https://{appl}/rest/interconnects/{id}/statistics'
provides a set of performance-related data.
My questions:
- The OneView REST only supports data for those interconnects supporting some sort of MIB, right? Meaning: OneView will not deliver any data for Synergy 20Gb Interconnect Link Module.
- More important: my main scenario is that I will have to investigate on a system reported as being slow. The moment I start, this state of being slow might well be over. So I am looking for data collected by the system over a past time interval to extract. As far as I got, the performance counters do only report a mean value, summed up over a defined time interval. Is there a tool offered by HP that allows to collect a set of data measurements (say, taken every minute) to investigate past problems? Or would it be up to the user to tailor something suitable for their needs by connecting to SNMP / REST on a regular base and collect the data as needed?
- Just for the case: there is no CLI as for other HP products?
Regards
Christof

Re: Historical data available for interconnects in OneView?
Hello Christofl,
- The OneView REST only supports data for those interconnects supporting some sort of MIB, right? Meaning: OneView will not deliver any data for Synergy 20Gb Interconnect Link Module.
Answer: Correct. 20Gb modules are Interconenct Link Module. Just like Pass-thru module.
2. More important: my main scenario is that I will have to investigate on a system reported as being slow. The moment I start, this state of being slow might well be over. So I am looking for data collected by the system over a past time interval to extract. As far as I got, the performance counters do only report a mean value, summed up over a defined time interval. Is there a tool offered by HP that allows to collect a set of data measurements (say, taken every minute) to investigate past problems? Or would it be up to the user to tailor something suitable for their needs by connecting to SNMP / REST on a regular base and collect the data as needed?
Could you please comment on this query with more clarifications ?
Regarding the Tool, I am not sure about any performance tool that can be used for Synergy Interconencts from HPE..
However will get back on this.
3. Just for the case: there is no CLI as for other HP products?
Answer : We do have CLI access to the interconnects. However its only meant for HPE Engineering and Troubleshooting.
For customer, The OneView is the interface to interact with the Interconencts.
Hope this helps.

Re: Historical data available for interconnects in OneView?
lo Sharis,
first, thanks for answering numbers 1. and 3.
Now, trying to elaborate a bit more on #2:
Actually, the question was more general, holding at least for these modules:
- Virtual Connect SE 16Gb FC Module for Synergy
- Virtual Connect SE 40Gb F8 Module for Synergy
but maybe as well for the 20GB module. Sorry for the confusion. Trying to be a bit more precise, I will focus on the two VIrtual Connect modules above in the list.
As far as I saw for those two, in OneView I can monitor at least the speed and the utilization. Looking up the REST interface manual / help, there are quite some counter values that might be obtained via the REST API. However, these data seem to represent the current throughput. There seems to be no way to get a list of data collected over a larger time range (say, one day with collecting every 5 minutes). The REST API offers a command to reset the counters, but this has to be triggered by the user. That might be ok in writing a small tool doing so, but maybe there is a way to have a set of measurements performed by the system and just extract the data (as a list) by sending one REST GET command, just specifying the time range for which to send over throughput data? Like the data delivered for the enclosures.

SolutionHello,
I did not found any option to gather historical data for a time period for the VC modules.
All we can see the current throughput using the REST API..
GET/rest/interconnects/{id}/statistics
Gets the statistics from an interconnect. Note: If a Virtual Connect SE 40Gb F8 Module for Synergy interconnect module is in 'Monitored' state, issuing a GET /rest/interconnects/{ID}/statistics will not provide any data. Note: For a Virtual Connect SE FC Module interconnect module, when issuing a GET /rest/interconnects/{ID}/statistics, firmware version 1.05.xx or later is required to return data and the number of samples returned is one less than the sample count configured in the logical interconnect group telemetry configuration.
Hope this helps.

Re: Historical data available for interconnects in OneView?
Did you find the way to monitor InterConnects? I would need stastic of the FC uplinks, but with 5.20.01 under Interconnect the Statistic and Advanced Statistic are empty. Is there way to monitor the InterConnect Uplinks?
We do also have "Virtual Connect SE 40Gb F8 Module for Synergy"

Re: Historical data available for interconnects in OneView?
Hello,
Please once check with the Powershell "Show-Portstatistics" cmdlet which give more Relevant information.
$Interconnect = Get-HPOVInterconnect "Encl1, Interconnect 1"
Show-HPOVPortStatistics $Interconnect
(Get-HPOVInterconnect "Encl1, Interconnect 1").ports | ? name -eq X1 | Show-HPOVPortStatistics
The Cmdlet will display the utilization (Format-Table view) or error (Format-List) statistics of a given Interconnect or Interconnect Port. The default view is Format-Table. Piping output to Format-List will display error statistics.
