Graphite only saves a week's data of a collectd custom exec plugin

Question

I only have a single retention configured in my storage-schemas.conf

[default_rentions]
pattern = .*
#retentions = 60s:7d,120s:31d,600s:365d,30m:9y
retentions = 15s:7d,5m:30d,15m:10y

All other collectd data is saved as expected, however any custom metric gathered via the Exec plugin is only saved for just a week.

collectd.conf config:

LoadPlugin exec

<Plugin exec>
    Exec "centos:centos" "/etc/collectd/site-benchmarks.pl"
</Plugin>

I've already tried forcefully manually resizing the existing whisper files using the retention times that I want it to be, but that didn't seem to fix the issue.

find ./ -type f -name '*.wsp' -exec whisper-resize.py --nobackup {} 15s:7d 5m:30d 15m:10y \;

I've also already tried removing the corresponding *.wsp files so that graphite builds them scratch, and that also didn't help. All new custom exec collected data is still only being saved for a week.

Anyone have any ideas on why only custom collectd exec plugin's data is saved with a retention of a week?

Update: I've even verified the updated retention configs have been applied to the whisper files. Example test wsp file whisper metadata output:

[centos@ip-172-16-16-124 apache-response-time]$ whisper-dump.py gauge-test.wsp

Answer 1

执行的脚本运行多长时间？

有可能点的提交速度比每15秒一次慢，导致丢失点数。如果没有足够的积分，碳将拒绝汇总数据。如果是这种情况，您可以降低xFilesFactor，它描述了聚合必须存在多少数据点。
