[mrtg] problem with router2 compact summary

[Forthofer Russ]

I just changed to uselastupdate=yes and it did not seem to affect the problem. Do I need to wait for another polling cycle to know for sure if that corrects the issue?

I am running routers2 v2.19.   Is the value I used for the polling cycle affecting this? I am using 10 minute intervals.  Should I be using 5 minute intervals (or longer intervals)?

This could be the race condition between updates and viewing that can sometimes leave the last value as unknown.  Does this still happen with the 'uselastupdate=yes' option set in the routers2.conf?  Which version of routers2 are you using (the later versions should not have this issue)?

If your update occurs at 12:04:59 then any views between 12:00:00 and 12:04:59 will have the last data point as 'unknown' due to the normalisation effect.  Routers2 attempts to compensate for this but may not always get it correct.  The 'uselastupdate=yes' option get around this at the cost of having down devices show the live graphs based on their last 'up' time rather than the current time.

Subject: [mrtg] problem with router2 compact summary

I am trying to use the compact summary page using routers2.   I can see that it is working, because I SOMETIMES have data on the page.   And some routers appear to usually have data, while others seldom do.  MRTG appears to be collecting data correctly, because if I select the interface, and display the daily graph for that interface, I do have data.  But the compact summary shows 0's in  Last, Avg, and Max.   Any help would be greatly appreciated.
