Ceph block devices are thin-provisioned, resizable and store data striped over multiple OSDs in a Ceph cluster. Ceph block devices leverage RADOS capabilities such as snapshotting, replication and consistency. Ceph’s RADOS Block Devices (RBD) interact with OSDs using kernel modules or the librbd library.
The Ceph Filesystem (CephFS) is a POSIX-compliant filesystem that uses a Ceph Storage Cluster to store its data. The Ceph filesystem uses the same Ceph Storage Cluster system as Ceph Block Devices, Ceph Object Storage with its S3 and Swift APIs, or native bindings (librados).
Use Influxdb to as storage for Prometheus.
In this pos I will show you how to install Postgresql on difrent Linux distributions.
I prefer to use Naemon (a fork of nagos) with Influxdb as a storage for graphical data.
The Alertmanager handles alerts sent by client applications such as the Prometheus server.
Install node-exporter to provides detailed information about the system, including CPU, disk, and memory usage.
Prometheus is an open-source monitoring system with a built-in noSQL time-series database. It offers a multi-dimensional data model, a flexible query language, and diverse visualization possibilities. Prometheus collects metrics from http nedpoint. Most service dind’t have this endpoint so you need optional programs that generate additional metrics cald exporters.
