Yes, getting a lot of the following messages: Jun 13 12:57:38 nfsen nfsen[14798]: Behind schedule Jun 13 13:03:37 nfsen nfsen[14798]: Behind schedule Jun 13 13:09:09 nfsen nfsen[14798]: Behind schedule
Post CPU upgrade, CPU usage is remaining under 20% on average but the nfdump process hits 100% pretty regularily The disks are SSD over NFS. I haven't seen anything telling in the iowait but seems the next best target. I may have to look into using the local storage over NFS-SSD but I think these are 15k disks :( Thanks for taking the time to assist! -----Original Message----- From: Jens Hektor [mailto:hek...@itc.rwth-aachen.de] Sent: Tuesday, 13 June 2017 12:34 PM To: nfsen-discuss@lists.sourceforge.net Subject: Re: [Nfsen-discuss] Stuttered Graphing in NFSEN Do you get any output from fgrep schedu /var/log/messages 30 kflows/s is quite a number. Are your disks fast enough? (SSD or something rotating?) Too me it looks familiar when my CPUs do not process the RRDs in time.
