/.pnp-internal/runtime_invalid.rrd: illegal attempt to update using time

  • Hello,

    I am having a small issue with pnp4nagios (v. 0.6.25) on my Nagios (4.2.4) installation.

    I have quite a few messages like this in perfdata.log


    2017-03-22 11:44:01 [27398] [0] RRDs::update /var/lib/pnp4nagios/.pnp-internal/runtime_update.rrd 1489506252:1

    It is always some ".../.pnp-internal/runtime_*.rrd" and the "using time" is always 1489506252 where as "update time" changes.


    1489506252 translates to "Tue Mar 14 16:44:12 CET 2017" and that is the time of the last reboot.

    The graphs for "Internal Statistics" looks OK.


    Any suggestion on what is going on here?

  • I'm coming back to this issue once more.


    Looking at the log-file today I see the following:


    The timestamp 1497855974 corresponds to the time when process_perfdata.pl was started (in gearman mode) and the "last update time timestamp" is always about 2 minutes prior to the log-entry-time.

    This repeats on average about every 7 minutes and corresponds to a new child-process being spawned.

    Looking at the Graphs for "pnp-internal" everything looks OK.


    Any suggestions why this is happening?
