Google Cadvisor is a great tool for monitoring Docker containers, but it only shows real-time data by default and does not store historical data. In order to store and display historical data, custom displays, you can integrate Cadvisor with Influxdb, Grafana, a foreign expert Brian Christner wrote an article "How to setup Docker monitoring", Describes the deployment method.Brian's approach is to manually r

for large-scale data processing, spark is a parallel, common batch processing engine. Workflows are defined in a similar and nostalgic-style mapreduce, but more capable than traditional Hadoop mapreduce. Apache Spark has its streaming API project, which allows continuous processing through short interval batches. Apache Spark itself does not require Hadoop operations. However, its data parallel pattern requires stable data optimization using a shared
extends the spark RDD API, allowing us to create a forward graph with any property that is bound to each node and edge. GRAPHX also provides a wide variety of operator diagram operators, as well as a library of common graph algorithms.Cluster Manager cluster managers at the bottom, spark can effectively scale from one compute node to hundreds of nodes. To achieve this goal while maximizing flexibility, spark can run on multiple cluster managers, incl
