OVs_NON_WELL_BEHAVED is not an error condition but an indication that these daemons can stay up independently of the core daemons like ovwdb, pmd, and trapd.  The ones you cite will always be OVs_NON_WELL_BEHAVED, as will others like nvpagerd.

You high ovwdb CPU rate on the other hand is not good.  Is your cache size properly adjusted?  Do "ovobjprint -S" and see what you object count is.  Then make certain that your cache size on ovwdb is at least 20% greater.  Otherwise the daemon will spend a lot of time allocating and reallocating storage to hold your object database in memory.

And you really should plan to move to a supported level of the code.  7.1.1 has not been supported ever since 7.1.3 came out over two years ago.  The current maintenance level on 7.1.3 is FixPack2, which means that you are 5 version of the code downlevel so far.  FixPack3 for 7.1.3 is in the works now.


But none of these things has anything to do with your problem.  graphing is done by xnmgraph on data collected by snmpCollect.

I am not an expert in this area but I do know that data will not graph if there are gaps in the data, and I'll bet that if you look in the snmpCollect log you will find lots of errors, producing those gaps.  Collections get deferred if an error occurs, which produces those gaps.  Offhand, I would guess that you cannot successfully poll 200 routers for data in 3 minutes.   If you quadruple the number of devices to collect from,  I'd suspect you have to more than quadruple the collection interval.  


Anybody else?

RE: [nv-l] graph and deamon problems





Hi to all,
 
It has been some days now that the grapher stopped to display the BandwidthUtilIn and BandwidthUtilOut (from MIB Data Collection) for the interfaces of the routers selected. Even though I can see that the data is collected for all the routers. I have changed the time interval from 1 min to 3 min but no effect. I should also mention that I was collecting data for about 50 routers without problems and the last month that number was increased to 200. I noticed also the following things which I don’t know if they are related. Two deamons trapgend and mgragentd even though running are OVs_NON_WELL_BEHAVED. The last thing is that the process running the ovwdb takes about 99 to 100% of CPU continuously.
 
Any Ideas?
