![]() This means that the commercial InfluxDB will be easier to scale horizontally,īut it also means that you have to manage the complexity of a distributed With storage and queries being handled by many nodes at once. The commercial InfluxDB offering is, by design, a distributed storage cluster The open source version of InfluxDB is similar. Storage for their core functionality: scraping, rule processing, and alerting. Prometheus servers run independently of each other and only rely on their local This is much more suitable to event logging than Prometheus'sĪppend-only file per time series approach.ĭescribes the differences between event logging and metrics recording. InfluxDB uses a variant of a log-structured merge tree for storage with a write ahead log, Strings, and millisecond resolution timestamps. Prometheus, by contrast, supports the float64 data type with limited support for Nanosecond resolution, and float64, int64, bool, and string data types. In addition, InfluxDB has a second level of labels calledįields, which are more limited in use. Like Prometheus, the InfluxDB data model has key-value pairs as labels, whichĪre called tags. The Prometheus Alertmanager additionally offers grouping, deduplication and More powerful query language for graphing and Rules, and the Alertmanager's notification functionality. Kapacitor’s scope is a combination of Prometheus recording rules, alerting InfluxDB offers continuous queries, which are equivalent to Prometheus The same scope differences as in the case of In combination they address the same problem space as Prometheus and the Scopeįor a fair comparison, we must also consider Still, there are significantĭifferences between Prometheus and InfluxDB, and both systems are geared Released almost a year after Prometheus development began, so we were unable toĬonsider it as an alternative at the time. With a commercial option for scaling and clustering. InfluxDB is an open-source time series database, Solution that can hold historical data long term, Graphite may be a better Prometheus offers a richer data model and query language, in addition to beingĮasier to run and integrate into your environment. ![]() PrometheusĪlso works well for many short-lived, frequently changing sets of time series. ![]() Samples are simply appended, old data may be kept arbitrarily long. Samples at arbitrary intervals as scrapes or rule evaluations occur. Prometheus also creates one local file per time series, but allows storing Time series is stored in a separate file, and new samples overwrite old ones RRD-style database that expects samples to arrive at regular intervals. Graphite stores time series data on local disk in the In Prometheus the same data could be encoded like this (assuming three api-server instances): api_server_http_requests_total -> 31 Response code 500 and the method POST to the /tracks endpoint wouldĬommonly be encoded like this in Graphite/StatsD: .500 -> 93 Instance as a dimension and being able to drill down into individualįor example, storing the number of HTTP requests to API servers with the This allows easy filtering, grouping, and matching by theseįurther, especially when Graphite is used in combination withĪggregated data over all monitored instances, rather than preserving the Prometheus encodes dimensions explicitly as key-value pairs, called labels, attached Names consist of dot-separated components which implicitly encode dimensions, ![]() However, Prometheus's metadata model is richer: while Graphite metric Graphite stores numeric samples for named time series, much like Prometheusĭoes. Should exist, what time series patterns mean trouble, etc.), and actively tries It has knowledge about what the world should look like (which endpoints Prometheus is a full monitoring and trending system that includes built-in andĪctive scraping, storing, querying, graphing, and alerting based on time seriesĭata.
