EMC/Netsight - interface and device statistics collection

Could you please share how you do it ?

Even in my small lab network it's a pain to enable statistics collection.
https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-setup-interface-and-device-statisti...

To do it for the device is OK as it's one click but to do it for every interface is a very annoying task.

I'd need to open every device one by one and select the ports and enable it.
Even worst let's say you replace a AP you need to remember to enable the stats collection in EMC ..... or if you add a new SSID.

Or do I don't unterstand it and you don't enable it for every interface in the network ?
Are there any plans to set it global so on every new device all interfaces are enabled by default ?

Thanks,
Ron

It would be great to have a less tedious way of enabling interface statistics.

Hi Ronald,

I'm not sure how to do this in Oneview directly, but in Console you can select multiple devices, then right click on them > Select Oneview > Collect Device Statistics.

You may already know about this though.

Tony

This may work for you.  I've done this in Netsight 7.0, not sure if it works in earlier versions.  In Oneview select a device group and click on the Devices menu item (highlighted in grey in the image below).  Then select all of the devices in the group and click on the piece of paper with the gear on it just below the Devices menu item (sorry, don't know the technical term for the button).  Then select View > Interfaces.  A new tab will appear with interfaces from all selected devices.  Select all of the devices and right click on one of them.  Select Collect Interface Statistics.  Then Interface Statistics window will appear.  Hope this helps.  It's a bit convoluted, maybe there is/will be a more elegant way to do this.

I've tried to do it for all switches at once but...

1) I've rx the error message that the switches are not the same model.
In that case I must sort out the same switch model and then run it for every switch model/family - not sure how EMC decide what is the same family because as far as I'd remeber I've selected only XOS devices and even then I've rx the error.

2) not all "interfaces" are shown in this flexview
For example - you'd also enable it on "other components" like the PSU (screenshot below) - I have no idea what that will do.

I think that is the main point... I don't unterstand what I get out of it = should I have it enabled for everything and also for the "other components".

What reports/views are affected if I don't enable it.

I wish someone from the EMC team would take the time and expain in it detail in a KB article.

If the answer is - yes, enable it for everything then I wonder why is it not done automatically if I just enable the device - or give us the option of device+all current&future interfaces&components

I.e. if I add another VLAN in the customers network I'd need to go to EVERY switch and enable it for the VLAN - EMC should help to make the job of the network team easier but not waste time with such task.

Ronald,  I'm at the limit of my knowledge on this subject.  As you mentioned, maybe someone from the EMC group can chime in or write an article regarding this procedure.

Thx Tony, I'll open a ticket if no one from the EMC group answers till next week.

Hi,
From Oneview, you can load interface Summary Flexview for up to 10 switches    


Multiselect and right click gear box and collect interface stats this way. Flexview in the web client is currently limited to 10 devices at the moment, but it helps with enabling interface collection on many ports.


Historical collection are generally used to build Oneview reports that show something historically. Top switches by CPU or by Memory. Top 100 interfaces by daily bandwidth, or active flows, or poe utilization. Where Console [Java Client] used flexviews which was dynamically pulled from SNMP, Collectors are used to make the web snappier as it just has to query the database for data instead of going out to every corner of the earth to build a view to see.

Personally, I don't enable it on all interfaces, I generally only enable it on uplinks and AP ports so I can see if there are wired interface error/historical usage. The biggest reason I could see not enabling it is the amount of stats generated and disk usage.
