Hi all. I have a "simple" usage of the tail plugin, something like:
<File "/var/log/postgres/5432/postgresql" >
Instance "pg-average-response"
<Match>
Regex "\- some_database \- .*duration: ([0-9][0-9]*\.[0-9]\{3\})"
DSType "CounterAdd"
Type "gauge"
Instance "some_database"
</Match>
</File>
To catch the total queries served on that "some_database". After 2 or 3
"collectd restart" at, say 3 pm, 4 pm and 5pm im watching souspicious CPU
spikes at that moments, and the counters also raise a lot at that point. Im
thinking that maybe the tail plugin is reading the hole file again, which would
explain the CPU and counter behaviour.
Of course, that is not the desired way to behave. If i am correct, there is a
way to the 'tailf' thing without the re-reading stuff?
Thanks!
Gerardo
