[mrtg] problem with router2 compact summary

[Steve Shipway]

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.
