prometheus 是否保证基础设施时序数据的持久化?
Does prometheus ensure persistency of time series data of infrastructure?
Prometheus 使用TSDB 数据库,它是内存数据库(用 GoLang 编写),它是临时存储,用于存储基础设施的时间序列指标。
Prometheus 应该提供时间序列指标,需要永久存储来存储信息。例如:CPU 主机上个月的指标。
prometheus如何处理时序数据的持久化(永久存储)?因为TSDB是内存数据库..
cortex storage与 TSDB 有何不同?
Prometheus TSDB 部分在内存中,部分在磁盘上。保留最近的数据 in-memory and backed up on-disk in WAL (write ahead log) segments, as it's the most frequently accessed. If the instance is shut down the in-memory data can be restored from the WAL. After a few hours the in-memory data is formally saved to the disk in the format of Blocks。因此,所有数据都会保留到其保留期限到期。
