When we migrated this to ansible I missed that we didn't bring across the storage-aggregation.conf file. This has had the unfortunate effect of regressing the xFilesFactor set for every newly created graphite stat since the migration. This setting is a percentage (0-1 float) of how much of a "bucket" needs to be non-null to keep the value when rolling up changes. We want this to be zero due to the sporadic nature of data (see the original change I5f416e798e7abedfde776c9571b6fc8cea5f3a33). This only affected newly created statistics, as graphite doesn't modify this setting once it creates the whisper file. This probably helped us overlook this for so long, as longer-existing stats were operating correctly, but newer were dropping data when zoomed out. Restore this setting, and double-check it in testinfra for the future. For simplicity and to get this back to the prior state I will manually update the on-disk .wsp files to this when this change applies. Change-Id: I57873403c4ca9783b1851ba83bfba038f4b90715 |
