[collectd] Tail plugin "missing" events

I think I understood the issue. The lines in the log appear 1000 times,
but most of them are the same, even the timestamp. So, there're really
up to 20 unique lines.

Is there any way to force collectd to count all the appearances and not
just the unique ones?


Thanks a lot

Subject: [collectd] Tail plugin "missing" events




I'm using the following configuration for my tail plugin:

Interval     10

ReadThreads  5


LoadPlugin load

LoadPlugin rrdtool

LoadPlugin syslog

LoadPlugin tail


<Plugin rrdtool>

  DataDir      "..."

  CacheTimeout  30

  CacheFlush    60





      RegEx    "listStudies userid:"

      DSType   "CounterInc"

      Type       "counter"

      Instance "listStudies"




After that, I'm issuing 1000 requests that should match the regular
expression, but RRD results only show at most up to 20 hits per sample.
It looks like the plugin is "missing" entries from the log file when
they come too quickly. Is there a workaround/solution for this problem
or I'm doing something wrong?


Thank you,
