    Hi, Gang.

    I hope that all is well. Recently, I finished migrating to a CentOS 7.4 system and then did an in-place upgrade to use the CloudLinux kernel. Since that time, various Munin graphs have values as nan, i.e., "not a number". The graphs with these values are as follows:

    Firewall Throughput
    Netstat
    VMstat
    Swap in/out

    The Munin version from the WHM 68.0.30 installed is 2.0.30-1.cp1162.

    Does anybody have any idea how I can restore these graphs to their former glory?

    Edited to Update: I uninstalled Munin and nuked /var/lib/munin, then reinstalled Munin. This resulted in Exim and Munin processing updating normally.

    Not quite. Only Exim and Munin processing were corrected. The other graphs remain problematic:

    Firewall Throughput
    Netstat
    VMstat
    Swap in/out

    Hello,

    There's a CloudLinux forums thread on this topic at:

    Restrictions on Munin

    In that case, here's the response to the support ticket referenced by the user in that thread:

    Here's the updated URL to the CloudLinux document referenced on that thread:

    Thank you.

    Thanks, Michael. Unfortunately, this made no difference. It's rather curious. All other graphs update normally. Just those four outliers.

    Belay that. There was simply a longer delay than expected in repopulating those graphs. An hour later, all is working as I hoped.

    Super! Many thanks for your help and patience, Michael.
