I just opened a support ticket on this one.  I'm not getting any graphs when I drill down to certain operations.  On one or two it works fine but on others I get "No Data for Selected Time Period" or just the image not found icon (black box with red X in center).

Anyone else having this issue?

After working with the very capable Solarwinds tech support and development staff we have determined that there is a Cisco bug which will cause graphs to break in IP SLA Manager after 49 days of uptime:

CSCin66315 - Inconsistency with sysuptime and rttMonLatestRttOperTime

It is resolved in 12.2(46)SG and 12.3(7)T.

I did a little math and I think I know what the bug is.  The number of "ticks" in 49 days is 423,360,000 which is pretty close visually to the maximum 32 bit integer which is 4,294,967,296.  My guess is that the programmer left out a digit when trying to detect a wrap condition.

I have a TAC case open still because the suggested IOS is not compatible with my hardware.  Hope this does not affect you!

Well I just got off the phone with Rick, the Manager of the TAC group that deals with such things.  He was very apologetic and finally was able to tell me what I already knew:  The fix for this bug has not yet been ported to the 12.2SX train yet which is what 6500's use.  He is going to get that moving ASAP.

I asked him if others should also open TAC cases and he said it cannot hurt.  So if your hardware does not support either of the two trains where this bug is already fixed then I encourage you to also open a case.

Worth noting is that the fix will almost certainly appear in 12.2SXJ which will be the first 6500 IOS to support EnergyWise.  If you're like me and have been waiting for this so you can use the capabilities that Orion already offers, you can kill two birds with one stone by going to SXJ.  No word when that will come out.  :-)

What graphs are you specifically having issues with?  Also, could you please email me screenshots of what you're seeing?  craig.mcdonald@solarwinds.com

Thanks!

Craig,

Screenshots on the way.  The graphs that don't appear are on any "Operation Details" page.  For instance, for a DNS operation you would normally see two graphs: (1) Min/Max/Avg Graph of Round Trip Time and (2) Operation Availability.  I have had these operations running for a couple of hours now and I still get "No Data to Display for Selected Time Period".  I have tried to change the time period as well as the sample period and I still get nothing.

I also opened a support ticket withe the same issue. Is there any workaround in the SLA Mgr itself ?

Right now I've no historical data for my SLA operations, and for me that is very unsatisfying.

I configured the operations on my core switch and seems that no new IOS is available.

 

Thanks

Andre

Andre, I have had a TAC case open for over a week.  They tried to close the case but I have not let them because they have yet to acknowledge that there's no fix or workaround for my hardware (mainly 6500).  By happy coincidence we're having a utility maintenance in the building this weekend which will cause most of my devices to power cycle.  I guess I've just bought myself 49 more days! :-)

Kahmeelyon, that sounds very annoying so I'll hope Cisco will fix your issue within the next weeks. I'm just looking forward that "our" Solarwinds support find another solution for my issue. I can't belive, that every IOS is affected with this bug.

I get no graphs no matter what combination I try to monitor via IP SLA in my company net. Not with my core switch neither on my edge routers. I would love to get some historical data  ;-(

Goose,

A couple of responses to you:

1. I'm surprised that this has not come up unil now.  VoIP Manager has been around for a while and I don't see why this bug didn't surface when the product was called that.

2. In fairness to Solarwinds they can't really be expected to fix Cisco bugs.  What we might expect in the future is a more rigorous testing cycle.  I know that this particular team did not have any 6500s to test on and seemed to test only on low end Cisco gear.  Apart from that, this is a Cisco bug pure and simple and I don't see any easy way to code around it without creating other possible issues.

I'm on with the TAC right now.  I have been ignored by the TAC engineer for over a week so now it's time to knock some heads.  I'll let you know how it goes.

There's no workaround in the current version of IPSLA Manager to the IOS bug being discussed here.  In this case, IP SLA Manager is reporting based on what the router tells it to report.

Can you give us a list of some of the IOSes you are encountering this issue on?

thanks!

Hi Kahmeelyon--

Could you give the TAC number for this case? This way we can include it in the KB article we will write addressing this issue.

Thanks,

M

kahmeelyon, thank for sharing that information. I think I'm going to restart that cisco devices I monitor in the SLA Manager this weekend. Do you get the the graphs from the point you restarted your switch til the 49 days are expired ?

Hi, a very strange thing happened. As I'm goining to configure the schedule for the device restart this night, I looked once again in the SAL Manager. And I was very surprised to see, that I've a graph in the sla operations detail since 3 pm this day. All I did was to follow the proposal of Alan from the Solarwinds support to change the language of the sa and the Netperfmon user in the SQL Manager to English. But that was yesterday morning.

Thats realy strange, but I'm happy :-)

BTW The devices have longer uptime than 49 days
