Aerospike¶
Aerospike Namespace 性能指标展示，包括集群、空间下的内存使用情况、磁盘使用、对象数、读写速率等。
Aerospike Node 相关指标展示，包括 Node 集群、Node 状态、记录数、内存、磁盘指标等。
安装配置¶
前置条件¶
- Aerospike 已安装
示例 Aerospike 版本为 Linux 环境 6.0.0 (CentOS)，各个不同版本指标可能存在差异。
aerospike-prometheus-exporter 为官方研发的 Exporter ，方便快速接入监控 Aerospike。
指标采集¶
安装 exporter¶
官方下载&安装 exporter 地址 https://docs.aerospike.com/monitorstack/install/linux
wget https://www.aerospike.com/download/monitoring/aerospike-prometheus-exporter/latest/artifact/rpm -O aerospike-prometheus-exporter.tgz
tar -xvzf aerospike-prometheus-exporter.tgz
配置 exporter¶
配置文件地址 /etc/aerospike-prometheus-exporter/ape.toml，默认 metrics 端口为 9145，默认采集端口为 3000，默认情况下不需要调整配置文件。
